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.

SQL Server™ 2000 includes several XML features that let you transform relational rowsets into hierarchical XML documents, read XML documents, and bulk load data via XML. For example, you can pass an XML document to a stored procedure, join the XML to some tables and return a rowset, or even modify data in the database.

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.

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.

As you move forward with your use of ADO. NET, you'll need to know how to approach situations that you previously learned to handle in ADO and now have to tackle with ADO. NET. Just as n-tiered solutions developed using Visual Basic®, C++, and ASP often rely on ADO for their data access needs, Windows® Forms, Web Forms, and Web services rely on ADO.

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.

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.

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.
