- Data Points: The Enterprise Library Data Access Application Block, Part 3
E nterprise applications can have a wide variety of data update requirements. Sometimes you need to save multiple rows of changes at once within a single transaction. Other times, the user must be allowed to enter multiple rows of data, send them to the database in a batch; and if a row or two fails, only the rows that succeeded should be committed and remain committed.
John Papa – October 2005

John Papa – November 2004
- Data Points: Handling Data Concurrency Using ADO.NET, Part 2
Enterprise development has been moving towards a discon-nected model in recent years and ADO. NET development is no exception. While the disconnected model of the ADO. NET DataSet offers great flexibility, that adaptability also means looser control over data updates than you get with a connected data access model.
John Papa – October 2004
- Data Points: Handling Data Concurrency Using ADO.NET
One of the key features of the ADO. NET DataSet is that it can be a self-contained and disconnected data store. It can contain the schema and data from several rowsets in DataTable objects as well as information about how to relate the DataTable objects—all in memory.

John Papa – May 2003
- Data Points: Expressions in ADO.NET
Managing relations in a database became a whole lot easier with ADO. NET. Instead of returning a single rowset to a data store, you can return a series of rowsets and relate them within a DataSet. There are numerous advantages to using related DataTables in ADO.
John Papa – January 2003
- Data Points: DataRelations in ADO.NET
One of the biggest differences between traditional ADO and ADO. NET is that the rowsets stored within ADO. NET can be truly relational. For example, a DataSet can store one DataTable containing customers and another DataTable containing the customers’ orders.

- Taming the Stateless Beast: Managing Session State Across Servers on a Web Farm
Running a Web farm means managing session state across servers. Since session state can’t be shared across a Web farm with Internet Information Services 5.0, a custom solution is required. One such solution using a tool called the session manager is described here. The article begins with a description of the SQL Server database used to store state information, the stored procedures used to update it, and the retrieval of session data. ASP code drives the session manager tool and the COM and COM+ components that run the stored procedures.
