This is an Oracle Data Layer class for connecting to Oracle Database from a .NET application

Oracle Data Provider for .NET (ODP.NET) is an implementation of a data providerfor the Oracle database.ODP.NET uses Oracle native APIs to offer fast and reliable access to Oracle data andfeatures from any .NET application. ODP.NET also uses and inherits classes andinterfaces available in the Microsoft .NET Framework Class Library.based on Oracle Data Provider.NET.

This C# class file contains two classes OracleDataAcess and OracleDataAccessParameterCache. We can easily manage the application Business layer by using this class. Here I give the sample code of the implementation of DataLayer in the Business Layer.

OracleParameter[] oraParam = new OracleParameter[2];

oraParam[0] = new OracleParameter("CustomerID", "100");
oraParam[1] = new OracleParameter("ResultCursor", OracleDbType.RefCursor);

oraParam[1].Direction = ParameterDirection.Output;

DataSet ObjDS =  OracleDataAccess.ExecuteDataset(connectionString, 
                 "Pr_GetCustomerDetails",oraParam );

Hi prasad,
Sorry for delay to send the reply for your comment, becs I was not here for last few months.
You can change the namespace with your application name like
"namespace Paragon.DataAccess" with
"namespace yoursolutionname.DataAccess"
And you should need to download and install ODP.Net from Oracle website, this is exclusively for free.
Once you installed the ODP.Net, you should give reference of Oracle.DataAccess library to your application. In your application layer, you give the reference of this datalayer and imports this namespace in your required pages
thanks and regards
