View 2 RepliesIn my asp.net application im using Oracle client. In the connection string, we specify the 3 basic attributes: data source, User Id, and Password. We are using connection pooling. Our data resides in 2 different Oracle schemas. Most of the requests are for data from both Schema1 and Schema2.
Is it possible that the connections are implicitly tied to a schema1 or schema2?

I have asp.net2005 on my system with sql server.
My Application uses two SQL databses, one for membership/roles (ASPNETDB.MDF) the other for my data. When deploying to a server do I have to use two connection strings, one for each database? I am using the publish to provider wizard with VWD 2008 to replicate the databases on Sqlserver 2008 (Windows server 2008 R2). I have my data connection working fine, I am just trying to get mebership and roles working.
View 3 RepliesI am supposed to develop an enterprise-class ASP.NET Web Application that connects to multiple databases. For example when the web form loads, I should populate different ASP.NET controls (GridView, DataPager, TextBox, DropdownList etc) from multiple databases (SQL Server, Oracle, DB2, SAP Server etc) and also, edit the data in the controls and save the data to the respective databases on button submit.
Should I use Web Service or WCF for data integration, if so is there a limit on the size of the data?
What should be the architecture considering the application should be scalable and easy to maintain?
Is the "asp.net - oracle" a good solution for web applications?

I'm using oracle for my asp.net website. In website I have 3 different roles. Now do I need to create as many diff users in oracle as roles?
Someone in team insisted on having as many users in oracle. But then unnecessarily i have to maintain multiple connection strings in app.
like, I have manager/ team leader/ user roles.
Now the team member insists on having 3 users in oracle. then in DAL i've to check role and use corresponding connection string.
This is not very big app, but in all 12-15 aspx pages and some 10 table in oracle to be used only on intranet.
what is best practice for this?
