  • How to connect to a legacy Informix database?

    - by ivo
    I have to connect my app to a customer's Informix 7.2 legacy database. From what I was able to find out, in theory there should be a database service running on port 50000. The problem is that I cannot find any database service in the Operative System. So far I'm only able to use dbaccess and perform queries from the command line. I would like to use a database driver (such as http://code.google.com/p/ibm-db/) so my app can connect and query the database using a cursor, but since I cannot find any database service, apparently I can't... Am I missing something here? Are there options I'm not considering? Is it possible to have an Informix database in which the only interface is dbaccess?

  • Installing SharePoint 2010 on a dev machine with an external database

    - by Dan Revell
    I've been following Microsoft's guide for installing a dev environment on Windows 7: http://msdn.microsoft.com/en-us/library/ee554869.aspx In order for it to not run like a dog I've created a SQL Server 2008 instance on our database server specifically for this dev machine. The article does mention that you might be wanting to use an external database in regard to making sure the database cumulative update is installed. It doesn't make any other mention of configuring it to use a external database. I was hoping that the configuration wizard would then prompt about which database to use but annoyingly it just set-up the configuration database locally. How do I go about installing SharePoint on a dev environment with an external database, and will I need to reformat this machine and do it all again?

  • How to use multiple database adapter to query involving tables from different databases?

    - by understack
    I've 2 databases, which are set up as mentioned here. How can I write a SQL query which involves database_1.table_1 and database_2.table_1 ? E.g. consider this query $sql = "SELECT distinct database_1.users.id, database_1.users.name FROM database_1.users, database_2.sales WHERE database_2.sales.user_id = database_1.users.id"; How this query could be written using multiple db adapter? Edit I'm using 2 databases, because this way I can change actual database names in application.ini. Is there any other way I can change database names without changing sql queries?

  • How to synchronize two DataBase Schemas Oracle 10G?

    - by gnash-85
    Hi Masters, Good Day, I am new and very naive to Oracle DB. I am using Oracle 10G. Let me explain to you. I have one source database named ( DB1) and Target Database named (DB2). I have 2 schema's named dbs1 and dbs2 in the source database (DB1). I have exported both the database schemas in Source Database (DB1) and imported it successfully into the Target Database (DB2). Now I face a challenge in synchronizing these database schemas every time from Source DB (DB1) to Target DB (DB2). Can anyone please help in letting me know how can achieve this synchronization? It would a great help. Thanks Nash

  • SQL Server 2008 EF 4 - limiting database records returned using permissions?

    - by Chuck
    In our database all tables are linked back to a single table. This table has a bit column to limit whether the record is displayed. Currently the records are filtered on the code side of the website. Is there any way to set up permission so that userA would never see any record in the database where that common bit column was set to true? We are using SQL Server 2008. Alternatively we are also using entity framework 4.0 in .net 4 (in c#) if you have any ideas how it might be accomplished there? Thanks for your feedback.

  • Inheriting database connection in PHP OOP

    - by vrode
    My abstract class Database is made for database interaction and any child of this class (UserDatabase, ActionDatabase, EventDatabase) inherits its database connection which is defined as static. `abstract class Database { static $connection = mysql_connect( ); } class UserDatabase extends Database { ... public function __construct( ) { $connection ? "connected" : "not connected"; $this-table = "users"; mysql_query( "FROM " . $this-table . " SELECT *" ); } } ` Does that mean, that my database connection is only set up and stored in memory once and passed on to subclasses as reference without being replicated for each instance? Is this how you would implement you OOP-correct database interface?

  • Best approach to creating a database driven Java website?

    - by Craig Whitley
    I'm fairly new to programming and new to java, but I'd like to jump in the deep end with a little database driven website project. I've read quite a lot about requirements in the 'real world' requesting experience with Spring and Hibernate, so I have those installed on netbeans and a project created (if I hit run I get the default spring page). Now I just need a little guidance as to where to start designing my app (please tell me if I'm getting in a bit too over my head for a beginner!). Should I start off with my classes? - create all my classes as they map to my database tables and decide which attributes and methods each will require? Can anyone suggest any good books for maybe.. making a java based website from scratch (i.e. from design right through to deployment) that might be useful for a beginner? Any help appreciated thanks.

  • How can I get Weblogic to connect to a RedBrick database?

    - by Scott
    I am trying to get Weblogic 9.2.3 to talk to a legacy RedBrick database and am having trouble. I have the redbrick.jar file from the software installation and have added to my APP_RUNTIME_CLASSPATH and my MANIFEST_CLASSPATH. This is my jConnect template line: <url>jdbc:rbw:protocol:${DB_LT_SERVER}:${DB_LT_PORT}/${DB_LT_NAME}</url> <driver-name>redbrick.jdbc.RBWDriver</driver-name> (Variables get replaced with good values during build.) When starting up I get this error: weblogic.common.ResourceException: Unknown Data Source jConnectLT weblogic.common.resourcepool.ResourceSystemException: Cannot load driver class: redbrick.jdbc.RBWDriver Do I have to do more to make Weblogic see the RedBrick database? Thanks for any tips or pointers.

  • Entity Framework Create Database & Tables At Runtime

    - by dhsto
    I created some tables in an .edmx file and have been generating the database by selecting "Generate Database From Model" and manually executing an .edmx.sql file on the database to build the tables. Now, however, I am creating a setup dialog that allows the user to connect the program up to their own database. I thought running context.CreateDatabase would be good enough to create the database, along with the tables, but the tables are not created. What is the preferred method for creating the database and tables when the user specifies their own server and database to use, when originally starting with a model?

  • Database/NoSQL - Lowest latecy way to retreive the following data...

    - by Nickb
    I have a real estate application and a "house" contains the following information: house: - house_id - address - city - state - zip - price - sqft - bedrooms - bathrooms - geo_latitude - geo_longitude I need to perform an EXTREMELY fast (low latency) retrieval of all homes within a geo-coordinate box. Something like the SQL below (if I were to use a database): SELECT * from houses WHERE latitude IS BETWEEN xxx AND yyy AND longitude IS BETWEEN www AND zzz Question: What would be the quickest way for me to store this information so that I can perform the fastest retrieval of data based on latitude & longitude? (e.g. database, NoSQL, memcache, etc)?

  • We failed trying database per custom installation. Plan to recover?

    - by Fedyashev Nikita
    There is a web application which is in production mode for 3 years or so by now. Historically, because of different reasons there was made a decision to use database-per customer installation. Now we came across the fact that now deployments are very slow. Should we ever consider moving all the databases back to single one to reduce environment complexity? Or is it too risky idea? The problem I see now is that it's very hard to merge these databases with saving referential integrity(primary keys of different database' tables can not be obviously differentiated). Databases are not that much big, so we don't have much benefits of reduced load by having multiple databases.

  • How to design a database schema for storing text in multiple languages?

    - by stach
    We have a PostgreSQL database. And we have several tables which need to keep certain data in several languages (the list of possible languages is thankfully system-wide defined). For example lets start with: create table blah (id serial, foo text, bar text); Now, let's make it multilingual. How about: create table blah (id serial, foo_en text, foo_de text, foo_jp text, bar_en text, bar_de text, bar_jp text); That would be good for full-text search in Postgres. Just add a tsvector column for each language. But is it optimal? Maybe we should use another table to keep the translations? Like: create table texts (id serial, colspec text, obj_id int, language text, data text); Maybe, just maybe, we should use something else - something out of the SQL world? Any help is appreciated.

  • How to count number of occurences for all different values in database column?

    - by drasto
    I have a Postgre database that has say 10 columns. The fifth column is called column5. There are 100 rows in the database and possible values of column5 are c5value1, c5value2, c5value3...c5value29, c5value30. I would like to print out a table that shows how many times each value occurs. So the table would look like this: Value(of column5) number of occurrences of the value c5value1 1 c5value2 5 c5value3 3 c5value4 9 c5value5 1 c5value6 1 . . . . . . What is the command that does that? Thanks for help

  • Best way for an external (remote) graphics designer to style ASP.NET MVC 4 app?

    - by Tom K
    My customer has his own graphics designer he wants to use to style his web application we're building in ASP.NET MVC 4. Our solution is in Bitbucket, but if he can't run it what choices do we have? I doubt he uses Visual Studio 2012. One idea is for us to publish to our solution to a file system, send it to him, have him create a local IIS website on his machine (assuming he isn't using a Mac). Mocking data or pointing to a test SQL in Azure isn't a problem. Then he can make changes to .css and .cshtml files. Will this even work? The point is that he needs to be able to test his changes. I know he can modify the views and just check-in. But he needs to deliver a working design. So it seems inefficient. The graphics designer will have access to our test site so he can see how it works, what data we have and fields. Another idea is for him to build a static mock site using just HTML/CSS. Later I'd integrate his styles into customer's solution, split his html into partial views which we use and add Razor syntax. Again, we'd like to leverage graphics designer for all of this. Is there a best practice documented around this subject? How do other teams deal with this situation?

  • Question about API and Web application code sharing

    - by opendd
    This is a design question. I have a multi part application with several user types. There is a user client for the patient that interacts with a web service. There is an API evolving behind the web service that will be exposed to institutional "users" and an interface for clinicians, researchers and admin types. The patient UI is Flex. The clinician/admin portion of the application is RoR. The API is RoR/rack based. The web service component is Java WS. All components access the same data source. These components are deployed as separate components to their own subdomains. This decision was made to allow for scaling the components individually as needed. Initially, the decision was made to split the code for the RoR Web application from the RoR API. This decision was made in the interests of security and keeping the components focused on specific tasks. Over the course of time, there is necessarily going to be overlap and I am second guessing my decision to keep the code totally separate. I am noticing code being lifted from the admin side being lifted, modified and used in the API. This being the case, I have been considering merging the Ruby based repositories. I am interested in ideas and insight on this situation along with the reasoning behind your thoughts. Thanks.

  • Do you need all that data?

    - by BuckWoody
    I read an amazing post over on ars technica (link: http://arstechnica.com/science/news/2010/03/the-software-brains-behind-the-particle-colliders.ars?utm_source=rss&utm_medium=rss&utm_campaign=rss) abvout the LHC, or as they are also known, the "particle colliders". Beyond just the pure scientific geek awesomeness, these instruments have the potential to collect more data than you can (or possibly should) store. Actually, this problem has a lot in common with a BI system. There's so much granular detail available in the source systems that a designer has to decide how, and how much, to roll up the data. Whenver you do that, you lose fidelity, but in many cases that's OK. Take, for example, your car's speedometer. You don't actually need to track each and every point of speed as it happens. You only need to know that you're hovering around the speed limit at a certain point in time. Since this is the way that humans percieve data, is there some lesson we should take in the design of data "flows" - and what implications does this have for new technologies like StreamInsight?

  • Game Components, Game Managers and Object Properties

    - by George Duckett
    I'm trying to get my head around component based entity design. My first step was to create various components that could be added to an object. For every component type i had a manager, which would call every component's update function, passing in things like keyboard state etc. as required. The next thing i did was remove the object, and just have each component with an Id. So an object is defined by components having the same Ids. Now, i'm thinking that i don't need a manager for all my components, for example i have a SizeComponent, which just has a Size property). As a result the SizeComponent doesn't have an update method, and the manager's update method does nothing. My first thought was to have an ObjectProperty class which components could query, instead of having them as properties of components. So an object would have a number of ObjectProperty and ObjectComponent. Components would have update logic that queries the object for properties. The manager would manage calling the component's update method. This seems like over-engineering to me, but i don't think i can get rid of the components, because i need a way for the managers to know what objects need what component logic to run (otherwise i'd just remove the component completely and push its update logic into the manager). Is this (having ObjectProperty, ObjectComponent and ComponentManager classes) over-engineering? What would be a good alternative?

  • Cost to licence characters or ships for a game

    - by Michael Jasper
    I am producing a game pitch document for a university game design class, and I am looking for examples of licencing cost for using characters or ships from other IP holders in a game. For example: cost of using an X-Wing in a game, licencing from Lucas cost of using the Enterprise in a game, licencing from Paramount cost of using the Space Shuttle (if any), licencing from Nasa EDIT The closest information I can find is from an article about Nights of the Old Republic, but isn't nearly specific enough for my needs: What Kotick means by Lucas being the principal beneficiary of the success of The Old Republic is that there are most likely clauses in the license agreement that give percentages, points, or another denomination of revenue out to Lucas and his people just for the Star Wars name, and that amount is presumed to be a great deal of money. Kotick is saying that because the cost of the license is so prohibitive, as he has personally had experience with in his position as CEO of Activision Blizzard, that EA will not be able to be profitable because of the hemorrhaging of money to the licensor. EDIT 2 Another vague source stating that FOX uses a "five-figure rule" (assuming between $10,000 - $99,000) It seems FOX, like most studios, will not license individuals to create new works based upon their products. They will only commission individuals of their choosing if they elect to branch out into expanded product lines related to those licenses. Alternately, they are open to making the licencing available to large corporations with access to global markets, but only if those corporations agree to what Ms Friedman called a "five-figure guarantee". Presumably this means that the corporation seeking the licensing must agree to pay a 5-figure sum for that license, and be confident that their product will sell enough volume to recoup that fee, and to produce sufficient profits to make the acquisition worth their while. Thank you!
