Week 3: At a Glance

for RuBoard

After learning about the two major components of ADO.NET during the last two weeks, you should now be ready to apply what you've learned in the context of multi- tier application development during this final week.

The first five days of this week focus on the design and implementation of multi-tier applications using ADO.NET. The week begins with a short introduction and overview of multi-tier development, and moves on to discuss techniques that you can apply in the presentation, business, and data services tiers on Days 16 and 17. On Day 18, the focus shifts slightly to the implementation of a data factory class that can be used internally in the data services tier to provide both .NET Data Provider and database independence. Day 19 presents a discussion of using ADO.NET in conjunction with XML Web Services.

Day 20 provides some performance and scalability tips in addition to techniques for interoperating with ADO 2.x Recordset objects. The week and this book conclude with a discussion of some future directions that ADO.NET and data access will likely take.
