If you need any more eyes for testing I would love to help.

Re: [U2] Friendfeed and U2 EDA similarities
So, no-one is actually doing active development and clever things with EDA? I was just wondering since UniVerse now has EDA, someone must be doing something wonderful with it besides ticking boxes in a tender document? Or is it a secret-squirrel VAR thing? :) Cheers, djm David Jordan wrote: The main benefit for EDA is to be able to tell clients that your application runs on Oracle, DB2, SQL Server, etc. The question is, how much of the Database needs to be put on the external database to satisfy a customer's expectation.

Re: [U2] Friendfeed and U2 EDA similarities
IIRC, the company that asked for it was losing sales to competitors for their app based purely on name-brand and needed to store data on DB2 for a customer. DB abstraction is a good thing. Would be cool if we had a real ORM, but as we have seen, instead of using industry practices, we have yet another very specialized tool. I think it works well, but I would be wary of MSV data when expecting live updates.

Re: [U2] Friendfeed and U2 EDA similarities
The main benefit for EDA is to be able to tell clients that your application runs on Oracle, DB2, SQL Server, etc. At the end of the day the customer may just run U2, but it enables a VAR to meet a criteria. Tender documents might require that products have to run on Oracle that would have denied U2 applications the opportunity. Termenos has sold their pick application on Oracle. As a banking system, customers feel more comfortable with Oracle as a database, so why loose the sale when you can say I run on Oracle. The question is, how much of the Database needs to be put on the external database to satisfy a customer's expectation. Do you just transport information for enquiry/data warehouse data or do you transfer the whole transaction database. One are to be aware is that most pick applications are pessimistic locking and SQL databases prefer optimistic locking for performance. It would usually require U2 to the only application updating the database.

[U2] Friendfeed and U2 EDA similarities
Found an small interesting article about how the web site friendfeed store their data within MySQL rather than using a non-sql database. The method is very, very similar to the U2 EDA. If anyone is interested in this EDA technique - http://bret.appspot.com/entry/how-friendfeed-uses-mysql or my article - http://mvdbs.com/2011/02/17/friendfeed-and-eda/ Cheers, djm - Learn and Do Excel and Share http://mvdbs.com http://mvdbs.com -- View this message in context: http://old.nabble.com/Friendfeed-and-U2-EDA-similarities-tp30953121p30953121.html Sent from the U2 - Users mailing list archive at Nabble.com. ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
