  • Friday tips #2

    - by Chris Kawalek
    Welcome to our second Friday tips blog! You can ask us questions using the hash tag #AskOracleVirtualization on Twitter and we'll do our best to answer them. Today we've got a VDI related question on linked clones: Question: I want to use linked clones with Oracle Virtual Desktop Infrastructure. What are my options? Answer by John Renko, Consulting Developer, Oracle: First, linked clones are available with the Oracle VirtualBox hypervisor only. Second, your choice of storage will affect the rest of your architecture. If you are using a SAN presenting ISCSI LUNS, you can have linked clones with a Oracle Enterprise Linux based hypervisor running VirtualBox. OEL will use OCFS2 to allow VirtualBox to create the linked clones. Because of the OCFS2 requirement, a Solaris based VirtualBox hypervisor will not be able to support linked clones on remote ISCSI storage. If you using the local storage option on your hypervisors, you will have linked clones with Solaris or Linux based hypervisors running VirtualBox. In all cases, Oracle Virtual Desktop Infrastructure makes the right selection for creating clones - sparse or linked - behind the scenes. Plan your architecture accordingly if you want to ensure you have the higher performing linked clones.

  • Is there really anything to gain with complex design? [duplicate]

    - by SB2055
    This question already has an answer here: What is enterprise software, exactly? 8 answers I've been working for a consulting firm for some time, with clients of various sizes, and I've seen web applications ranging in complexity from really simple: MVC Service Layer EF DB To really complex: MVC UoW DI / IoC Repository Service UI Tests Unit Tests Integration Tests But on both ends of the spectrum, the quality requirements are about the same. In simple projects, new devs / consultants can hop on, make changes, and contribute immediately, without having to wade through 6 layers of abstraction to understand what's going on, or risking misunderstanding some complex abstraction and costing down the line. In all cases, there was never a need to actually make code swappable or reusable - and the tests were never actually maintained past the first iteration because requirements changed, it was too time-consuming, deadlines, business pressure, etc etc. So if - in the end - testing and interfaces aren't used rapid development (read: cost-savings) is a priority the project's requirements will be changing a lot while in development ...would it be wrong to recommend a super-simple architecture, even to solve a complex problem, for an enterprise client? Is it complexity that defines enterprise solutions, or is it the reliability, # concurrent users, ease-of-maintenance, or all of the above? I know this is a very vague question, and any answer wouldn't apply to all cases, but I'm interested in hearing from devs / consultants that have been in the business for a while and that have worked with these varying degrees of complexity, to hear if the cool-but-expensive abstractions are worth the overall cost, at least while the project is in development.

  • Ubuntu Tools for recovering data from damaged USB Flash Drive ~ 10 Gb

    - by PREDA LUCIAN
    I have technical issues with my USB Flash Drive - JetFlash®V15 (TS16GJFV15) It's very critical situation because I can not see the data from it and I should get a way to recover them ASAP. So, in general, I have connected Non-stop that USB Flash Disk at my laptop. Was appear Power surges and when I was coming back, I saw that problem with it. Details regarding JetFlash®V15 (in present): - when I connect it on USP slot, the led is working intermittent and later on remain with constant light. - if I inspect the computer drivers, I found "Generic USB Flash Disk" (when the stick it's connected). - if I inspect "Properties", I can see next details: --- Type: unknown (application/octet-stream) --- Size: unknown --- Volume: unknown --- Accessed: unknown --- Modified: unknown I inspected that stick on 2 different computers (as well in different different USB Ports) and was the same problem, I can not see the content. I was checking with Windows 7 and Ubuntu 10.04 OS, but without success. With both OS was working before this issue. I'll appreciate an answer which will solve the problem, not an answer which will certify the problem. What I have to do, to recover the information form it (nearly 10 Gb)? I'm looking forward to be guided from a technical expert.

  • Use of list-unsubscribe to improve inbox delivery

    - by Jeffrey Simon
    To overcome email being classified as spam by Gmail, Google recommends a number of steps, which we have implemented (namely SPF, DKIM, and Precedence: bulk). One additional measure they recommend at https://support.google.com/mail/bin/answer.py?hl=en&answer=81126#authentication reads as follows: Because Gmail can help users automatically unsubscribe from your email, we strongly recommend the following: Provide a 'List-Unsubscribe' header which points to an email address where the user can unsubscribe easily from future mailings (Note: This is not a substitute method for unsubscribing). Documentation for List-Unsubscribe is found at http://www.list-unsubscribe.com/. From this documentation I expect a button to be provided by a supported mail client. I have tested the 'List-Unsubscribe' header and it does not appear to provide the button. I have tested in both Gmail and OS X Mail. I tested with an http address and with both an email address and an http address. The format of the header is as follows: List-Unsubscribe: <mailto:[email protected]>, <http://domain.com/member/unsubscribe/[email protected]?id=12345N> No button appears in any test. My questions: How widely is List-Unsubscribe supported? Should a button be appearing somewhere, or does something else have to be present? I have seen a comment that even if the button is not present, services like Gmail, Yahoo, Hotmail/Windows Live would give higher regard to email having the header. Thus it might be worthwhile for this aspect alone. Please note that our standard email footer already contacts instructions and a link to allow unsubscribing from our email. Finally, is it worth while to implement this header? (That is, any downsides?)

  • Share text message on selected media

    - by Siddharth
    I want to share text data on player selected social media. Basically I want to implement functionality like following link represent for android. Send Text Content I want to give user a choice for sharing on Twitter, Facebook, Messaging, Gmail etc. Above link give proper guidance for my question. Here is code that work on android Intent sendIntent = new Intent(); sendIntent.setAction(Intent.ACTION_SEND); sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send."); sendIntent.setType("text/plain"); startActivity(sendIntent);Intent sendIntent = new Intent(); sendIntent.setAction(Intent.ACTION_SEND); sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send."); sendIntent.setType("text/plain"); startActivity(sendIntent); I don't know same functionality implementation in Unity. Basically at present I am targeting two platform for my game Android iOS I found answer for Android platform but I can't able to get answer of iOS platform. Share text message on selected media - Unity Forum Now I think my question is clear to all of you. So please help me to solve it.

  • What is the best way to exploit multicores when making multithread games?

    - by Keeper
    Many people suggest to write a program, and then start optimizing it. But I think that when it's coming to multithreading with multicore, a little think ahead is required. I've read about using threads, and experienced it myself during some courses at the university (still a student). The big question is simple, but a bit abstract: What thread related steps in game design do I need to take, before implementation? Now trying to be more specific. Let's say, as an example, that I'm making a small board game (like Monopoly) that I want to be multithreaded. My goal Is that this multithreaded game will exploit the best of the multicore system, lets say 4-6 cores (like in i7 processors). My answer to this question at the moment is, one thread for each of these four basic components: GUI User Input / Output AI (computer rival) Other game related calculations (like shortest path from A to B, or level up status change) I'm not an expert (yet!), and I'm sure there are better answers out there. Any suggestion, answer, different approach will be helpful. Some thoughts: Maybe splitting the main database is a good way.. (or total disaster.. )

  • How to convince non-programmer his notions about computers are wrong?

    - by Suma
    Recently I came across a question about 64b on SuperUser for which the accepted answer seemed like a complete nonsense to me. I made two comments pointing out obvious mistakes. To my perplexion, the comments had an effect of the poster of the answer being alienated. I have no idea how could I convince him he is wrong, as he does not seem to understand the basics of the problem. He seems to be mixing concepts like bus size and address size - see the pearl sentence "it will allow you to address all of your RAM because your processor is reading from your RAM in 64 bit words.". The poster asks me to provide proves of my claim by quoting a respectable source, but I have no idea where to find such source, as I doubt anything I would consider relevant would be relevant for him (it would be probably too technical). I think this instance can serve as an illustration of communication problems between programmers and users (and to certain extent even to any expert vs. non-expert communication). How should a programmer handle a communication like this, so that is does not become a useless quarrel?

  • How are objects modelled in a functional programming language?

    - by Giorgio
    In an answer to this question (written by Pete) there are some considerations about OOP versus FP. In particular, it is suggested that FP languages are not very suitable for modelling (persistent) objects that have an identity and a mutable state. I was wondering if this is true or, in other words, how one would model objects in a functional programming language. From my basic knowledge of Haskell I thought that one could use monads in some way, but I really do not know enough on this topic to come up with a clear answer. So, how are entities with an identity and a mutable persistent state normally modelled in a functional language? EDIT Here are some further details to clarify what I have in mind. Take a typical Java application in which I can (1) read a record from a database table into a Java object, (2) modify the object in different ways, (3) save the modified object to the database. How would this be implemented e.g. in Haskell? I would initially read the record into a record value (defined by a data definition), perform different transformations by applying functions to this initial value (each intermediate value is a new, modified copy of the original record) and then write the final record value to the database. Is this all there is to it? How can I ensure that at each moment in time only one copy of the record is valid / accessible? One does not want to have different immutable values representing different snapshots of the same object to be accessible at the same time.

  • Eliminating zero-length files

    - by RhZ
    I have been having multiple crashes recently. 4-5 last night within a few hours. I posted about it before, and got an answer but not sure how to proceed. The messages in my logs right before the crash are multiple complaints about valid eCryptfs headers. But the chron might not be related, I don't think I saw that in previous crashes: xxx-desktop kernel: [ 1112.274474] Valid eCryptfs headers not found in file header region or xattr region, inode 32376924 xxx-desktop CRON[4212]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) So I was sent to an answer providing this script: for i in find $(mount | grep " on $HOME type ecryptfs" | awk '{print $1}') -size 0c; do if ! fuser -v $i; then rm -f $i fi done I did find some zero byte files, not in the exactly right place (a folder called .private as I remember), but I need to fix this, its too bad right now. So I need to delete any of them that are not in use. I am a little too clueless, can someone walk me through executing this script? I don't know how.

  • How to avoid "DO YOU HAZ TEH CODEZ" situations?

    - by volothamp
    I have a strange situation at work, where a colleague of mine often asks me and other co-workers for working code. I would like to help him, but this constant request of trivial snippets interrupts my thoughts and sometimes makes it hard to concentrate. Plus, I have the impression (...) that this requests are generated by lack of competence, more than by laziness. In fact, he often asks things pretending to know the answer, since when I solve the problem he usually says things like "Sure", "Yes, that's what I thought", giving me the impression that my answer isn't worth it. How can I solve this embarrassing situation? Should I show more explicitly in front of other colleagues his lack of knowledge (by saying things like: "do it yourself if you can, please") or continue giving him what he wants? I think that he should aggregate all his answers in one, so that I can give him a portion of my time and he can work all by himself on his things. There is no hierarchy in the team, I must say we both have a similar seniority of five years, more or less. For the same reason I believe I cannot report to management, since trivial questions are often ignored. I discussed with other two members and they agree with me: in fact he often ask things cycling through colleagues.

  • In an online questionnaire, what is a best way to design a database for keeping track of users all attempts?

    - by user1990525
    We have a web app where users can take online exams. Exam admin will create a questionnaire. A questionnaire can have many Questions. Each question is a multiple choice question (MCQ). Lets say an admin creates a questionnaire with 10 questions. Users attempt those questions. Now, unlike real exams users can attempt single questionnaire multiple times. And we have to keep track of his all attempts. e.g. User_id Questionnaire_id question_id answer attempt_date attempt_no 1 1 1 a 1 June 2013 1 1 1 2 b 1 June 2013 1 1 1 1 c 2 June 2013 2 1 1 2 d 2 June 2013 2 Now it can also happen that after user has attempted same questionnare twice, admin can delete a question from same questionnaire, but users attempt history should still have reference to that so that user can see his that question in his attempt history in spite of admin deleting that question. If user now attempts this changed questionnaire he should see only 1 question. User_id Questionnaire_id question_id answer attempt_date attempt_no 1 1 1 a 3 June 2013 3 Also, after this user modified some part of question, users attempt history should show question before modification while any new attempt should show modified question. How do we manage this at the database level? My first gut feeling was that, For deletes, do not do physical delete, just make a question inactive so that history can still keep track of users attempt. For modifications, create versions for questions and each new attempt refres to latest version of each question and history keeping reference to version of question at attempt time.

  • Finding maximum number of congruent numbers

    - by Stefan Czarnecki
    Let's say we have a multiset (set with possible duplicates) of integers. We would like to find the size of the largest subset of the multiset such that all numbers in the subset are congruent to each other modulo some m 1. For example: 1 4 7 7 8 10 for m = 2 the subsets are: (1, 7, 7) and (4, 8, 10), both having size 3. for m = 3 the subsets are: (1, 4, 7, 7, 10) and (8), the larger set of size 5. for m = 4 the subsets are: (1), (4, 8), (7, 7), (10), the largest set of size 2. At this moment it is evident that the best answer is 5 for m = 3. Given m we can find the size of the largest subset in linear time. Because the answer is always equal or larger than half of the size of the set, it is enough to check for values of m upto median of the set. Also I noticed it is necessary to check for only prime values of m. However if values in the set are large the algorithm is still rather slow. Does anyone have any ideas how to improve it?

  • Reasons behind polymorphism related behaviour in java

    - by Shades88
    I read this code somewhere class Foo { public int a; public Foo() { a = 3; } public void addFive() { a += 5; } public int getA() { System.out.println("we are here in base class!"); return a; } } public class Polymorphism extends Foo{ public int a; public Poylmorphism() { a = 5; } public void addFive() { System.out.println("we are here !" + a); a += 5; } public int getA() { System.out.println("we are here in sub class!"); return a; } public static void main(String [] main) { Foo f = new Polymorphism(); f.addFive(); System.out.println(f.getA()); // SOP 1 System.out.println(f.a); // SOP 2 } } For SOP1 we get answer 10 and for SOP2 we get answer 3. Reason for this is that you can't override variables whereas you can do so for methods. This happens because type of the reference variable is checked when a variable is accessed and type of the object is checked when a method is accessed. But I am wondering, just why is it that way? Can anyone explain me what is the reason for this behaviour

  • Advice and resources on collaborative environments

    - by Tjaart
    I need some advice on collaborative software environments. More specifically, I am looking for books and reference materials that can aid me in understanding team and code structures and the interactions thereof. In other words books, blogs or white papers explaining: Different strategies for structuring teams that share common code between each other but have distinct individual functions? To summarise my question I would like to know what would be a good source of knowledge if I were to set up teams in an organisation that shared code but each unit still remained autonomous. I have done some research on this subject and explored: code review tools, distributed VCS, continuous integration tools, Unit testing automation. The tough part about implementing these tools are to determine where a good place would be to start, which tools are low hanging fruit, which tools or methods provide higher success rates. If someone asks me about code quality reference I point them to Code Complete. I am looking for an equivalent guide on software team structures and tools to make this equation work better. I realise that this question is quite vague but it arose as "we need to share code between teams without breaking each others stuff and causing management headaches and reams of red tape" The answer is definitely not simple and requires changes on many levels, hence the question. If the question is too vague please vote to close or delete. I would accept any good starting point as an answer.

  • What happens when you close an Adsense account?

    - by rakibtg
    I need to change my payee name, I have asked in Google Adsense product forum one of top contributor replied me: "You will have to close the account & apply again with using your real payee name. That's why they specifically state that the payee name needs to match the full name on your bank account." https://support.google.com/adsense/answer/47333?hl=en This makes sense, but got few question because the support page do not have sufficient content to help me. My questions are: What happens when you close your Adsense account? If I apply again, then what will be the process to re-gain my account? I mean should I have to apply for a website again, then Adsense team will review and approve that? Is there any chance to disapprove my account? What about current check? I have two check in my hand. So, is Google will send those check again to me with my new payee name? Anyone experienced this problem? I have asked it on Google Forum but got no answer!

  • Seek first to understand, then to be understood

    - by BuckWoody
    One of the most important (and most difficult) lessons for a technical professional to learn is to not jump to the solution. Perhaps you’ve done this, or had it happen to you. As the person you’re “listening” to is speaking, your mind is performing a B-Tree lookup on possible solutions, and when the final node of the B-Tree in your mind is reached, you blurt out the “only” solution there is to the problem, whether they are done or not. There are two issues here – both of them fatal if you don’t factor them in. First, your B-Tree may not be complete, or correct. That of course leads to an incorrect response, which blows your credibility. People will not trust you if this happens often. The second danger is that the person may modify their entire problem with a single word or phrase. I once had a client explain a detailed problem to me – and I just KNEW the answer. Then they said at the end “well, that’s what it used to do, anyway. Now it doesn’t do that anymore.” Which of course negated my entire solution – happily I had kept my mouth shut until they finished. So practice listening, rather than waiting for your turn to speak. Let the person finish, let them get the concept out, give them your full attention. They’ll appreciate the courtesy, you’ll look more intelligent, and you both may find the right answer to the problem.

  • How to match responses from a server with their corresponding requests? [closed]

    - by Deele
    There is a server that responds to requests on a socket. The client has functions to emit requests and functions to handle responses from the server. The problem is that the request sending function and the response handling function are two unrelated functions. Given a server response X, how can I know whether it's a response to request X or some other request Y? I would like to make a construct that would ensure that response X is definitely the answer to request X and also to make a function requestX() that returns response X and not some other response Y. This question is mostly about the general programming approach and not about any specific language construct. Preferably, though, the answer would involve Ruby, TCP sockets, and PHP. My code so far: require 'socket' class TheConnection def initialize(config) @config = config end def send(s) toConsole("--> #{s}") @conn.send "#{s}\n", 0 end def connect() # Connect to the server begin @conn = TCPSocket.open(@config['server'], @config['port']) rescue Interrupt rescue Exception => detail toConsole('Exception: ' + detail.message()) print detail.backtrace.join('\n') retry end end def getSpecificAnswer(input) send "GET #{input}" end def handle_server_input(s) case s.strip when /^Hello. (.*)$/i toConsole "[ Server says hello ]" send "Hello to you too! #{$1}" else toConsole(s) end end def main_loop() while true ready = select([@conn, $stdin], nil, nil, nil) next if !ready for s in ready[0] if s == $stdin then return if $stdin.eof s = $stdin.gets send s elsif s == @conn then return if @conn.eof s = @conn.gets handle_server_input(s) end end end end def toConsole(msg) t = Time.new puts t.strftime("[%H:%M:%S]") + ' ' + msg end end @config = Hash[ 'server'=>'test.server.com', 'port'=>'2020' ] $conn = TheConnection.new(@config) $conn.connect() $conn.getSpecificAnswer('itemsX') begin $conn.main_loop() rescue Interrupt rescue Exception => detail $conn.toConsole('Exception: ' + detail.message()) print detail.backtrace.join('\n') retry end

  • How to work with processes?

    - by Viesturs
    I have seen similar questions here, but I didn't get my answer. Maybe it's because I am new to all this and just don't understand. I want my app to work mostly as an indicator. And if user would start it again it would check if it is already running, if it is then give all the input data to that process and quit. So first I need to check if it is running. I saw the answer where you can make a file witch when the program starts and then check if it exists... But what if someone would delete it? Can't I just ask the OS if there is process named "myApp" or something? The next thing I don't really get is how to communicate with the process. How do I give it the input data and what is it going to do with it? Does it work just like starting a new app, through the main() method? I am trying to create this using Quickly. So it would be nice if you can give me some python examples or link to something like that.

  • One sentence descriptions of the various common software licenses?

    - by Rich
    Instead of having to read entire documentation and sift through all the legalese, can someone outline the more common licenses in language that is short and sweet and gets right to the point? Specifically, I'm using a 3rd party control that uses the Apache 2.0 license. My intention is to use this in a proprietary application that I am building for a corporation's use (not resold, but I'm being paid for my work). Does this mean I can or cannot use this control? Does it mean that I must maintain copyright/license information in my code? Does it mean that I must mention copyright/license information in a clearly visible location in the app? EDIT In response to an answer below with a link to an article by Jeff Atwood, the Apache license is described as follows: Apache License Open Permissive 9 Requires derivative works to provide notification of any licensed or proprietary code in a common location. Does this notification need to be in a "common location" in my source code or a common location visible within the app? What if this were a non GUI app (I'm assuming that could very well be my answer)? Thanks for the responses!!!

  • Git for beginners: The definitive practical guide

    - by Adam Davis
    Ok, after seeing this post by PJ Hyett, I have decided to skip to the end and go with git. So what I need is a beginners practical guide to git. "Beginner" being defined as someone who knows how to handle their compiler, understands to some level what a makefile is, and has touched source control without understanding it very well. "Practical" being defined as this person doesn't want to get into great detail regarding what git is doing in the background, and doesn't even care (or know) that it's distributed. Your answers might hint at the possibilities, but try to aim for the beginner that wants to keep a 'main' repository on a 'server' which is backed up and secure, and treat their local repository as merely a 'client' resource. Procedural note: PLEASE pick one and only one of the below topics and answer it clearly and concisely in any given answer. Don't try to jam a bunch of information into one answer. Don't just link to other resources - cut and paste with attribution if copyright allows, otherwise learn it and explain it in your own words (ie, don't make people leave this page to learn a task). Please comment on, or edit, an already existing answer unless your explanation is very different and you think the community is better served with a different explanation rather than altering the existing explanation. So: Installation/Setup How to install git How do you set up git? Try to cover linux, windows, mac, think 'client/server' mindset. Setup GIT Server with Msysgit on Windows How do you create a new project/repository? How do you configure it to ignore files (.obj, .user, etc) that are not really part of the codebase?

  • How does this decorator make a call to the 'register' method?

    - by BryanWheelock
    I'm trying to understand what is going on in the decorator @not_authenticated. The next step in the TraceRoute is to the method 'register' which is also located in django_authopenid/views.py which I just don't understand because I don't see anywhere that register is even mentioned in signin() How is the method 'register' called? def not_authenticated(func): """ decorator that redirect user to next page if he is already logged.""" def decorated(request, *args, **kwargs): if request.user.is_authenticated(): next = request.GET.get("next", "/") return HttpResponseRedirect(next) return func(request, *args, **kwargs) return decorated @not_authenticated def signin(request,newquestion=False,newanswer=False): """ signin page.

  • Survey Data Model - How to avoid EAV and excessive denormalization?

    - by AlexDPC
    Hi everyone, My database skills are mediocre at best and I have to design a data model for survey data. I have spent some thoughts on this and right now I feel that I am stuck between some kind of EAV model and a design involving hundreds of tables, each with hundreds of columns (and thousands of records). There must be a better way to do this and I hope that the wise folks on this forum can help me. I have already searched various forums, but I couldn't really find a solution. If it has already been given elsewhere, please excuse me and provide me with a link so I can read it up. Some assumptions about the data I have to deal with: Each survey consists of 1 to n questionnaires Each questionnaire consists of 100-2,000 questions (please ignore that 2,000 questions really sound like a lot to answer...) Questions can be of various types: multiple-choice, free text, a number (like age, income, percentages, ...) Each survey involves 10-200 countries (These are not the respondents. The respondents are actually people in the countries.) Depending on the type of questionnaire, each questionnaire is answered by 100-20,000 respondents per country. A country can adapt the questionnaires for a survey, i.e. add, remove or edit questions The data for one country is gathered in a separate database in that country. There is no possibility for online integration from the start. The data for all countries has to be integrated later. This means for example, if a country has deleted a question, that data must somehow be derived from what they sent in order to achieve a uniform design across all countries I will have to write the integration and cleaning software, which will need to work with every country's data In the end the data needs to be exported to flat files, one rectangular grid per country and questionnaire. I have already discussed this topic with people from various backgrounds and have not come to a good solution yet. I mainly got two kinds of opinions. The domain experts, who are used to working with flat files (spreadsheet-style) for data processing and analysis vote for a denormalized structure with loads of tables and columns as I described above (1 table per country and questionnaire). This sounds terrible to me, because I learned that wide tables are to be avoided, it will be annoying to determine which columns are actually in a table when working with it, the database will become cluttered with hundreds of tables (or I even need to set up multiple databases, each with a similar yet a bit differetn design), etc. O-O-programmers vote for a strongly "normalized" design, which would effectively lead to a central table containing all the answers from all respondents to all questions. This table would either need to contain a column of type sql_variant type or multiple answer columns with different types to store answers of different types (multiple choice, free text, ..). The former would essentially be a EAV model. I tend to follow Joe Celko here, who strongly discourages its use (he calls it OTLT or "One True Lookup Table"). The latter would imply that each row would contain null cells for the not applicable types by design. Another alternative I could think of would be to create one table per answer type, i.e., one for multiple-choice questions, one for free text questions, etc.. That's not so generic, it would lead to a lot of union joins, I think and I would have to add a table if a new answer type is invented. Sorry for boring you with all this text and thank you for your input! Cheers, Alex PS: I asked the same question here: http://www.eggheadcafe.com/community/aspnet/13/10242616/survey-data-model--how-to-avoid-eav-and-excessive-denormalization.aspx
