• two sql queries in one place

  - by Luke

  <?php $results = mysql_query("SELECT * FROM ".TBL_SUB_RESULTS."

• fire jquery .animate oninput only once

  - by luke

  http://jsfiddle.net/nFFuD/ I'm trying to animate the search field in this example using jquery, making it move to the top of it's containing div oninput. I was originally using scriptaculous effect.move to do this, but I couldn't make the event only fire once, so if someone kept typing after the first keystroke, the effect would stop and start again from it's current position in the animation for each additional keystroke, which is stupid. I'm new to new to using jquery so please, take it easy if I'm not making very much sense.

• Looping through with dates

  - by Luke

  I have created a fixture generator for football/ soccer games... $totalRounds = $teams - 1; $matchesPerRound = $teams / 2; $rounds = array(); $roundDates = array(); $curTime = time(); for ($i = 1; $i <= $totalRounds; $i++) { $rounds[$i] = array(); $numDays = $i * 4; $roundDates[$i] = strtotime("+".$numDays." days",$curTime); } foreach($roundDates as $time) { for ($round = 0; $round < $totalRounds; $round++) { for ($match = 0; $match < $matchesPerRound; $match++) { $home = ($round + $match) % ($teams - 1); $away = ($teams - 1 - $match + $round) % ($teams - 1); // Last team stays in the same place while the others // rotate around it. if ($match == 0) { $away = $teams - 1; } $rounds[$round][$match] = "$user[$home]~$team[$home]@$user[$away]~$team[$away]~$time"; } } } In the code, for $i = 1, i thought that if you want the first date 4 days from now, the i must be 1, so 1 * 4 = 4. If i was 0, 0 * 4 equals 0. I assume this is correct thinking? Anyway the main question is, trying to generate the dates isn't working. When i created a fixture list for 4 users home and away, I got 12 fixtures. 10 of these had the same date on them, and the other 2 didnt have a date. Can anyone help me with this? Thanks

• How do I replace "this" in Java with something that works.

  - by Luke Alderton

  I'm looking to get the showGUI() method work, the compiler says "this" is not a static variable and cannot be referenced from a static context, what would I use to replace "this"? I've tried test.main (test being the package it's in). The reason I'm using the static method showGUI() is because I need the method to be called from another static method, as well as the startup() method. Below are my two main classes. public class Main extends SingleFrameApplication { @Override protected void startup() { showGUI(); } @Override protected void configureWindow(java.awt.Window root) { } public static Main getApplication() { return Application.getInstance(Main.class); } public static void main(String[] args) { launch(Main.class, args); } public static void showGUI() { show(new GUI(this)); } } public class GUI extends FrameView { public GUI(SingleFrameApplication app) { super(app); initComponents(); } private void initComponents() { //all the GUI stuff is somehow defined here } }

• Syntax problem when checking for a file

  - by Luke

  This piece of code has previously worked but I have C&P it to a new place and for some reason, it now won't work! <? $user_image = '/images/users/' . $_SESSION['id'] . 'a.jpg'; if (file_exists(realpath(dirname(__FILE__) . $user_image))) { echo '<img src="'.$user_image.'" alt="" />'; } else { echo '<img src="/images/users/small.jpg" alt="" />'; } ?> As you can see, I am checking for a file, if exists, showing it, if not, showing a placeholder. The $_SESSION['id'] variable does exist and is being used elsewhere within the script. Any ideas what the problem is? Thanks

• Zend Framework 2 without MVC

  - by Luke

  I'm currently using Zend Framework 2 for all my web tier development using the MVC module that's shipped with the framework. However, I want to implement my business logic in a separate layer, call it the business tier which is a non HTTP layer and expose it through AMQP, and I'd like to reuse my knowledge of PHP for implementing this. Since there is a lot of "stuff" that I need in this business layer such as configuration, a service manager, database access, etc, etc, I'd like to use all the goodies shipped with Zend Framework 2 for this. Are there any examples or tutorials out there on how to build a Zend Framework 2 application that is not build for the web tier and doesn't require the MVC module?

• What is a .NET application domain?

  - by Luke

  In particular, what are the implications of running code in two different application domains? How is data normally passed across the application domain boundary? Is it the same as passing data across the process boundary? I'm curious to know more about this abstraction and what it is useful for. EDIT: Good existing coverage of the AppDomain class in general at http://stackoverflow.com/questions/622516/i-dont-understand-appdomains

• Use AJAX to check for a new message

  - by Luke

  Quite simply, I need to alert the end user when they have a new private message. From a combination of research and other opinion, I realise I need to use AJAX for this. The mysql query would be SELECT id FROM tbl_messages WHERE to_viewed = 1 So when someone sends a message, I want an alert to popup on the screen to inform the user without a page reload. I have absolutely no idea what I am doing, but know what I want. Really need help with this, AJAX is definitely something I want to improve as it opens up greater possibilities! Thanks

• Second query to SQLite (on iPhone) errors.

  - by Luke

  Hi all, On the iPhone, I am developing a class for a cart that connects directly to a database. To view the cart, all items can be pulled from the database, however, it seems that removing them doesn't work. It is surprising to me because the error occurs during connection to the database, except not the second time I connect even after the DB has been closed. #import "CartDB.h" #import "CartItem.h" @implementation CartDB @synthesize database, databasePath; - (NSMutableArray *) getAllItems { NSMutableArray *items = [[NSMutableArray alloc] init]; if([self openDatabase]) { const char *sqlStatement = "SELECT * FROM items;"; sqlite3_stmt *compiledStatement; if(sqlite3_prepare_v2(cartDatabase, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { while(sqlite3_step(compiledStatement) == SQLITE_ROW) { int rowId = sqlite3_column_int(compiledStatement, 0); int productId = sqlite3_column_int(compiledStatement, 1); NSString *features = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; int quantity = sqlite3_column_int(compiledStatement, 3); CartItem *cartItem = [[CartItem alloc] initWithRowId:rowId productId:productId features:features quantity:quantity]; [items addObject:cartItem]; [cartItem release]; } } sqlite3_finalize(compiledStatement); } [self closeDatabase]; return items; } - (BOOL) removeCartItem:(CartItem *)item { sqlite3_stmt *deleteStatement; [self openDatabase]; const char *sql = "DELETE FROM items WHERE id = ?"; if(sqlite3_prepare_v2(cartDatabase, sql, -1, &deleteStatement, NULL) != SQLITE_OK) { return NO; } sqlite3_bind_int(deleteStatement, 1, item.rowId); if(SQLITE_DONE != sqlite3_step(deleteStatement)) { sqlite3_reset(deleteStatement); [self closeDatabase]; return NO; } else { sqlite3_reset(deleteStatement); [self closeDatabase]; return YES; } } - (BOOL) openDatabase { if(sqlite3_open([databasePath UTF8String], &cartDatabase) == SQLITE_OK) { return YES; } else { return NO; } } - (void) closeDatabase { sqlite3_close(cartDatabase); } The error occurs on the line where the connection is opened in openDatabase. Any ideas? Need to flush something? Something gets autoreleased? I really can't figure it out. --Edit-- The error that I receive is GDB: Program received signal "EXC_BAD_ACCESS". --Edit-- I ended up just connecting in the init and closing in the free methods, which might not be the proper way, but that's another question altogether so it's effectively persistent instead of connecting multiple times. Still would be nice to know what was up with this for future reference.

• They may block off Howard Street—but Oracle OpenWorld is a two-way street.

  - by Oracle Accelerate for Midsize Companies

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 by Jim Lein, Sr. Director, Oracle Accelerate for Midsize Companies “Engineered to Inform and Inspire”—that’s the theme of Oracle OpenWorld 2012. In early October, tens of thousands of attendees will descend on the streets of San Francisco because they share one thing in common: the desire to learn more about Oracle. You might think that’s the way we, Oracle employees, look at this event—as just another opportunity for attendees to learn about what we do. But it’s really a two way street. Every year I’m amazed by how informed and inspired I am by our customers and their companies. Midsize companies buy Oracle to grow. As part of the Oracle Accelerate for Midsize Companies team I get to talk with our partners and business leaders at growing companies almost every day, usually via phone. Oracle OpenWorld presents the perfect opportunity to meet some of them in person, in an informal setting, and in one of the most beautiful cities in the world. The stories our customers tell me about their businesses provide vivid examples of how they have overcome the challenges of managing increasingly complex global operations and growing during uncertain economic conditions. It’s no secret that my favorite session at Oracle OpenWorld (besides Larry Ellison’s keynotes and the Customer Appreciation Event, of course) is the Oracle Accelerate Customer Panel. This year we’re featuring executives from three companies who deployed Oracle ERP rapidly to support their company’s growth: Chris Powell, VP and Corporate Controller of Beats by Dr. Dre, a California based designer and manufacturer of premium headphones (sorry, no free samples), Iñaki Zuazo, CIO of Industrias Juno, a building materials provider based in Spain, Kamran Moosa, Project Coordinator for Spartan Engineering, a provider of engineering and construction support services for an LPG storage project in Texas, and That’s a pretty diverse lineup and it will be interesting to hear the perspectives of both IT and financial project stakeholders. The session, “Oracle Accelerate Customer Case Studies: Rapid Deployment of Oracle Applications”, is at 3:30 pm on Wednesday, October 3, in the Concert room at the Palace Hotel. Oracle loves our hometown of San Francisco and it’s a great place to host Oracle OpenWorld. It’s now San Francisco’s largest conference and the city closes off Howard Street to better accommodate the attendees. Some Bay Area commuters may be inconvenienced for a few days by this closure but the conference brings about $100 million into the local economy. Now that’s a two-way street.

• Focus on Social Relationship Management at Oracle OpenWorld

Today, we’re going to focus on Social Relationship Management at Oracle OpenWorld.?Social networking is touching all businesses today.  Customers are speaking about your brand right now on social media sites. Your employees are speaking to one another on social media sites. In an Oracle survey, 40% of consumers factor in Facebook recommendations when making purchasing decisions. Despite the rise of social networking, 70% of marketers report having little understanding of social media conversations happening around their brand. Oracle has invested in technologies that will help companies leverage social media technologies for their enterprise. Our suite of social products is collectively known as Social Relationship Management. Customers are using Social Relationship Management to get analytics to social media conversations around their brand, manage multiple social media channels while keeping their brand consistent, optimize internal workflows and processes, and create better customer relationships and experiences. In this example, using Social Relationship Management, a high-end national grocery chain is able to see that “Coconut Water” is trending in San Francisco. They are now able to send a $2-off coconut water coupon to shoppers who have checked into their San Francisco locations. This promotion further drives sales of coconut water in San Francisco. In another example, using Social Relationship Management, a technology company creates multiple Facebook pages and runs campaigns on them. These social campaigns are now integrated and tracked as another marketing channel in Oracle Fusion CRM. The technology company can now track and respond to a particular customer as he moves across multiple channels – without having to restart the conversation each time the customer contacts the company. Furthermore, the technology company can see in one interface what marketing channels – including social – is performing best for each promotion. Besides being a Software-as-a-Service solution, social is also a Platform-as-a-Service solution. The benefit here is that customers can extend the functionality of our social applications to suit their particular needs or create their own social application from scratch. During the Social Developer track, developers are learning how to use Java and other industry-standard programming languages to plug in social functionality to enterprise applications. To see how Social Relationship Management can help your business build better relationships and experience with customers, visit us on the web at oracle.com/social. There are a lot more social-oriented sessions left at OpenWorld. To view a schedule of the upcoming social-oriented sessions, go here.

• JavaOne Latin America 2012 Trip Report

  - by reza_rahman

  JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. The conference was a resounding success with a great vibe, excellent technical content and numerous world class speakers. Some notable local and international speakers included Bruno Souza, Yara Senger, Mattias Karlsson, Vinicius Senger, Heather Vancura, Tori Wieldt, Arun Gupta, Jim Weaver, Stephen Chin, Simon Ritter and Henrik Stahl. Topics covered included the JCP/JUGs, Java SE 7, HTML 5/WebSocket, CDI, Java EE 6, Java EE 7, JSF 2.2, JMS 2, JAX-RS 2, Arquillian and JavaFX. Bruno Borges and I manned the GlassFish booth at the Java Pavilion on Tuesday and Webnesday. The booth traffic was decent and not too hectic. We met a number of GlassFish adopters including perhaps one of the largest GlassFish deployments in Brazil as well as some folks migrating to Java EE from Spring. We invited them to share their stories with us. We also talked with some key members of the local Java community. Tuesday evening we had the GlassFish party at the Tribeca Pub. The party was definitely a hit and we could have used a larger venue (this was the first time we had the GlassFish party in Brazil). Along with GlassFish enthusiasts, a number of Java community leaders were there. We met some of the same folks again at the JUG leader's party on Wednesday evening. On Thursday Arun Gupta, Bruno Borges and I ran a hands-on-lab on JAX-RS, WebSocket and Server-Sent Events (SSE) titled "Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket". This is the same Java EE 7 lab run at JavaOne San Francisco. The lab provides developers a first hand glipse of how an HTML 5 powered Java EE application might look like. We had an overflow crowd for the lab (at one point we had about twenty people standing) and the lab went very well. The slides for the lab are here: Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket from Reza Rahman The actual contents for the lab is available here. Give me a shout if you need help getting it up and running. I gave two solo talks following the lab. The first was on JMS 2 titled "What’s New in Java Message Service 2". This was essentially the same talk given by JMS 2 specification lead Nigel Deakin at JavaOne San Francisco. I talked about the JMS 2 simplified API, JMSContext injection, delivery delays, asynchronous send, JMS resource definition in Java EE 7, standardized configuration for JMS MDBs in EJB 3.2, mandatory JCA pluggability and the like. The session went very well, there was good Q & A and someone even told me this was the best session of the conference! The slides for the talk are here: What’s New in Java Message Service 2 from Reza Rahman My last talk for the conference was on JAX-RS 2 in the keynote hall. Titled "JAX-RS 2: New and Noteworthy in the RESTful Web Services API" this was basically the same talk given by the specification leads Santiago Pericas-Geertsen and Marek Potociar at JavaOne San Francisco. I talked about the JAX-RS 2 client API, asyncronous processing, filters/interceptors, hypermedia support, server-side content negotiation and the like. The talk went very well and I got a few very kind complements afterwards. The slides for the talk are here: JAX-RS 2: New and Noteworthy in the RESTful Web Services API from Reza Rahman On a more personal note, Sao Paulo has always had a special place in my heart as the incubating city for Sepultura and Soulfy -- two of my most favorite heavy metal musical groups of all time! Consequently, the city has a perpertually alive and kicking metal scene pretty much any given day of the week. This time I got to check out a solid performance by local metal gig Republica at the legendary Manifesto Bar. I also wanted to see a Dio Tribute at the Blackmore but ran out of time and energy... Overall I enjoyed the conference/Sao Paulo and look forward to going to Brazil again next year!

• Is there an "embedded DBMS" to support multiple writer applications (processes) on the same db files

  - by Amir Moghimi

  I need to know if there is any embedded DBMS (preferably in Java and not necessarily relational) which supports multiple writer applications (processes) on the same set of db files. BerkeleyDB supports multiple readers but just one writer. I need multiple writers and multiple readers. UPDATE: It is not a multiple connection issue. I mean I do not need multiple connections to a running DBMS application (process) to write data. I need multiple DBMS applications (processes) to commit on the same storage files. HSQLDB, H2, JavaDB (Derby) and MongoDB do not support this feature. I think that there may be some File System limitations that prohibit this. If so, is there a File System that allows multiple writers on a single file? Use Case: The use case is a high-throughput clustered system that intends to store its high-volume business log entries into a SAN storage. Storing business logs in separate files for each server does not fit because query and indexing capabilities are needed on the whole biz logs. Because "a SAN typically is its own network of storage devices that are generally not accessible through the regular network by regular devices", I want to use SAN network bandwidth for logging while cluster LAN bandwidth is being used for other server to server and client to server communications.

• JSON and Microformats

  - by Tauren

  I'm looking for opinions on whether microformats should be used to name JSON elements. For instance, there is a microformat for physical addresses, that looks like this: <div class="adr"> <div class="street-address">665 3rd St.</div> <div class="extended-address">Suite 207</div> <span class="locality">San Francisco</span>, <span class="region">CA</span> <span class="postal-code">94107</span> <div class="country-name">U.S.A.</div> </div> There is a document available on using JSON and Microformats. The information above could be represented as JSON data like this: "adr": { "street-address":"665 3rd St.", "extended-address":"Suite 207", "locality":"San Fransicso", "region":"CA", "postal-code":"94107", "country-name":"U.S.A." }, The issue I have with this is that I'd like my JSON data to be as lightweight as possible, but still human readable. While still supporting international addresses, I would prefer something like this: "address": { "street":"665 3rd St.", "extended":"Suite 207", "locality":"San Fransicso", "region":"CA", "code":"94107", "country":"U.S.A." }, If I'm designing a new JSON API right now, does it make sense to use microformats from the start? Or should I not really worry about it? Is there some other standard that is more specific to JSON that I should look at?

• Relational vs. Dimensional Databases, what's the difference?

  - by grautur

  I'm trying to learn about OLAP and data warehousing, and I'm confused about the difference between relational and dimensional modeling. Is dimensional modeling basically relational modeling, but allowing for redundant/un-normalized data? For example, let's say I have historical sales data on (product, city, # sales). I understand that the following would be a relational point-of-view: Product | City | # Sales Apples, San Francisco, 400 Apples, Boston, 700 Apples, Seattle, 600 Oranges, San Francisco, 550 Oranges, Boston, 500 Oranges, Seattle, 600 While the following is a more dimensional point-of-view: Product | San Francisco | Boston | Seattle Apples, 400, 700, 600 Oranges, 550, 500, 600 But it seems like both points of view would nonetheless be implemented in an identical star schema: Fact table: Product ID, Region ID, # Sales Product dimension: Product ID, Product Name City dimension: City ID, City Name And it's not until you start adding some additional details to each dimension that the differences start popping up. For instance, if you wanted to track regions as well, a relational database would tend to have a separate region table, in order to keep everything normalized: City dimension: City ID, City Name, Region ID Region dimension: Region ID, Region Name, Region Manager, # Regional Stores While a dimensional database would allow for denormalization to keep the region data inside the city dimension, in order to make it easier to slice the data: City dimension: City ID, City Name, Region Name, Region Manager, # Regional Stores Is this correct?

• Excel VBA Macro for Pivot Table with Dynamic Data Range

  - by John Ziebro

  CODE IS WORKING! THANKS FOR THE HELP! I am attempting to create a dynamic pivot table that will work on data that varies in the number of rows. Currently, I have 28,300 rows, but this may change daily. Example of data format as follows: Case Number Branch Driver 1342 NYC Bob 4532 PHL Jim 7391 CIN John 8251 SAN John 7211 SAN Mary 9121 CLE John 7424 CIN John Example of finished table: Driver NYC PHL CIN SAN CLE Bob 1 0 0 0 0 Jim 0 1 0 0 0 John 0 0 2 1 1 Mary 0 0 0 1 0 Code as follows: Sub CreateSummaryReportUsingPivot() ' Use a Pivot Table to create a static summary report ' with model going down the rows and regions across Dim WSD As Worksheet Dim PTCache As PivotCache Dim PT As PivotTable Dim PRange As Range Dim FinalRow As Long Dim FinalCol As Long Set WSD = Worksheets("PivotTable") 'Name active worksheet as "PivotTable" ActiveSheet.Name = "PivotTable" ' Delete any prior pivot tables For Each PT In WSD.PivotTables PT.TableRange2.Clear Next PT ' Define input area and set up a Pivot Cache FinalRow = WSD.Cells(Application.Rows.Count, 1).End(xlUp).Row FinalCol = WSD.Cells(1, Application.Columns.Count). _ End(xlToLeft).Column Set PRange = WSD.Cells(1, 1).Resize(FinalRow, FinalCol) Set PTCache = ActiveWorkbook.PivotCaches.Add(SourceType:= _ xlDatabase, SourceData:=PRange) ' Create the Pivot Table from the Pivot Cache Set PT = PTCache.CreatePivotTable(TableDestination:=WSD. _ Cells(2, FinalCol + 2), TableName:="PivotTable1") ' Turn off updating while building the table PT.ManualUpdate = True ' Set up the row fields PT.AddFields RowFields:="Driver", ColumnFields:="Branch" ' Set up the data fields With PT.PivotFields("Case Number") .Orientation = xlDataField .Function = xlCount .Position = 1 End With With PT .ColumnGrand = False .RowGrand = False .NullString = "0" End With ' Calc the pivot table PT.ManualUpdate = False PT.ManualUpdate = True End Sub

• Creating Emulated iSCSI Target in a Lab/Testing Environment using Windows Server 2008 R2

  - by Brian McCleary

  We have a single server running Windows Server 2008 with Hyper-V installed running 5 virtual machines. I have purchased a second DELL R805 Server so that we can create a fail-over cluster to our current R805 that is currently in production. Right now, our R805 connects via iSCSI to a MD3000i iSCSI SAN. Before we try to roll out the second server and clustering to our production environment, I want to be able to test and "play with" the clustering features in our lab before rolling it out. The problem is that I don't want to spend a couple thousand dollars on another iSCSI SAN server just for testing. I already have two servers in my lab that are installed with Windows Server 2008 R2 64bit (one is the R805 and another spare desktop that was laying around) and with the Hyper-V roll enabled that should be ready to test with, but I don't have an iSCSI target to use as the Cluster Shared Volume. Is there anyway to install, either on a Hyper-V image or on a external spare computer that we have some sort of emulated iSCSI target? In our lab, we obviously don't need a real SAN, just something that we can test out how to setup the clustering properly outside of our production environment. Any advise is appreciated. FYI - I have read Jose Barret's blog on WUDSS at http://blogs.technet.com/josebda/archive/2008/01/07/installing-the-evaluation-version-of-wudss-2003-refresh-and-the-microsoft-iscsi-software-target-version-3-1-on-a-vm.aspx, but it seems awfully complex. I'm hoping for an easier solution.

• Thoughts on ODTUG Kscope12

  - by thatjeffsmith

  The rodeo rocked! This wasn’t my first rodeo, and it wasn’t my first Kscope, but it was probably my favorite one. What is Kscope? It’s the annual conference for the Oracle Development Tools User Group. 1,000+ attendees from 20+ countries with an average Jeff Klout score of 65. I just made that metric and score up, but this conference attracts the best and brightest in the Oracle database space. I’m not just talking about the speakers either. The attendees are all top notch. They actively participate in sessions, make an effort to get to know their fellow conference mates, and often turn into volunteers and speakers. Developers that enjoy unit testing, understand the importance of modeling your data, and are eager to understand the Oracle CBO – these are traits that describe the ‘average’ ODTUG developer. 2012′s event was held in San Antonio. Yes, it was very hot. But this might have been the nicest Marriott property I’ve ever visited, and I’ve stayed at some nice ones in Hawaii and St. Thomas. They had free WiFi everywhere – the rooms, the Conference Center, the lobby, bars, everywhere. And it worked. The after hours events were very fun. I embarrassed myself several times, but that’s OK. The rodeo was an awesome event and the Thirsty Games experience was something I hope does not make it onto YouTube or Facebook — talking to you Chet Justice. I finally got to meet and spend some time with some folks I’ve always wanted to get to know better, @timothyjgorman, @alexgorbachev, @lj_dobson, @dschleis, @kentGraziano, @chriscmuir, @GaloBalda, @patch72, and many, many more! I even made some new friends thanks to the Mentor program and @carol_finn. 2013′s event will be in New Orleans. If you haven’t joined ODTUG or haven’t made it to Kscope, go ahead and mark your calendars. I had 3 presentations this year. Sunday’s was not a good performance, and I want to apologize to anyone who was there and was hoping for more. My Tips and Debugging sessions on Monday and Tuesday were more to my liking, and I enjoyed them as a presenter. I hope you enjoyed them as an attendee. I understand that my slidedecks were corrupted on the ODTUG site, and I’m working with the coordinator now to get those fixed ASAP. Apparently the 2 most well-received Tips was the /*CSV*/ formatting hint and recalling your previous SQL history via the keyboard. I’ll be doing a follow-up webinar with ODTUG in a few weeks for those members that weren’t able to see my Tips and Debugger sessions in San Antonio. I’ll be sure to post details on that here when I have the details. My next scheduled conference is Oracle Open World, and I may have a couple of shows after that to round out 2012.

• Four Easy Ways to Save a Rocky CRM Relationship

  - by Divya Malik

   Today, I am pleased to introduce our guest blogger Luke Christianson. Luke is  an Application Sales rep based out of Minneapolis, MN.  You can find him on LinkedIn and follow him on Twitter. In any relationship, sooner or later, the excitement fades away.  The honeymoon period gives way to the old routines you had, before you committed to each other and you eventually begin doing things apart from one another.  I’m not talking about a marriage…  Well, I guess I am.Commitment to a CRM tool and building a deep and lasting relationship is not much different than the basics of a traditional love story.  After your controlled CRM pilot program, and maybe the National Sales Meeting where you couldn’t escape those three wonderful letters, CRM, you will soon find that if you haven’t designed an environment where it’s going to enable your reps to make more money, the relationship is doomed.   . If you’re currently in a dysfunctional CRM relationship, here are 4 simple tips to re-engaging users and getting that spark back. Shadow a Sales Rep:   Chances are you can find out exactly what is preventing your sales reps from using the application by simply watching how they go about their day.  Sales reps are driven by money, not by additional administrative duties.  Your system needs to be setup so that they can get the information they need quickly, facilitate making key updates and run their business out of one easy-to-use application.  Increase your sales team’s productivity by 5% automatically:    Cancel the weekly forecast calls with your reps and require them update their opportunities in CRM.  Something else that I’ve seen work extremely well, is when you do Monthly or Quarterly reviews, do not let your sales reps bring anything into the room with them; no spreadsheets, notebooks, or computers.  Everything they need to tell you should be able to be put into CRM and fully accessible by the Sales Manager at any time.  Tool time:      Make sure the tools that you have selected meet both your short-term goals and your long term goals.   You need tools that can adapt like your business does.  You probably can’t wait two months for an update to a picklist value or for the addition of a simple workflow rule.  Do you feel the tools that are in place can create the experience you want for your users? and finally, if all else fails... Keep It Simple, Stupid:     Do you really need to require 15 fields to create an Opportunity?  Do you need to clutter the interface with different reports that don’t add daily value?  Most CRM systems on the market today are flexible enough today that your admin could clean up most of the unnecessary interface ‘noise’ in a few hours.  If they're not, see #3. Every strong relationship can be tedious at times, you’ll fight and eventually make amends, you may even threaten to upgrade to a newer model…  But be patient and think about what you want to achieve and you’ll find a partner for life.

• Create a unique ID by fuzzy matching of names (via agrep using R)

  - by tbrambor

  Using R, I am trying match on people's names in a dataset structured by year and city. Due to some spelling mistakes, exact matching is not possible, so I am trying to use agrep() to fuzzy match names. A sample chunk of the dataset is structured as follows: df <- data.frame(matrix( c("1200013","1200013","1200013","1200013","1200013","1200013","1200013","1200013", "1996","1996","1996","1996","2000","2000","2004","2004","AGUSTINHO FORTUNATO FILHO","ANTONIO PEREIRA NETO","FERNANDO JOSE DA COSTA","PAULO CEZAR FERREIRA DE ARAUJO","PAULO CESAR FERREIRA DE ARAUJO","SEBASTIAO BOCALOM RODRIGUES","JOAO DE ALMEIDA","PAULO CESAR FERREIRA DE ARAUJO"), ncol=3,dimnames=list(seq(1:8),c("citycode","year","candidate")) )) The neat version: citycode year candidate 1 1200013 1996 AGUSTINHO FORTUNATO FILHO 2 1200013 1996 ANTONIO PEREIRA NETO 3 1200013 1996 FERNANDO JOSE DA COSTA 4 1200013 1996 PAULO CEZAR FERREIRA DE ARAUJO 5 1200013 2000 PAULO CESAR FERREIRA DE ARAUJO 6 1200013 2000 SEBASTIAO BOCALOM RODRIGUES 7 1200013 2004 JOAO DE ALMEIDA 8 1200013 2004 PAULO CESAR FERREIRA DE ARAUJO I'd like to check in each city separately, whether there are candidates appearing in several years. E.g. in the example, PAULO CEZAR FERREIRA DE ARAUJO PAULO CESAR FERREIRA DE ARAUJO appears twice (with a spelling mistake). Each candidate across the entire data set should be assigned a unique numeric candidate ID. The dataset is fairly large (5500 cities, approx. 100K entries) so a somewhat efficient coding would be helpful. Any suggestions as to how to implement this?
