LINQ for VB 2005

Posted by IDM under Database, Dot NET

Book Description
Are you ready for the future of data access in .NET?

At the Microsoft Professional Developers Conference (PDC) 2005, Microsoft previewed a new technology, Language-Integrated Query (LINQ). It captured a lot of attention because it addressed the fundamental issue of merging object-oriented applications with relational data. The LINQ Project team demonstrated how to use LINQ to query a variety of data sources, such as a SQL Server database, an XML file, and an array, and how to manage the data using an object-oriented approach.

In Foundation Flex for Developers, Sas and Koen assume that you’ve got the basics of Flex down already, and explores in detail how to create professional data-centric Flex 2 and Flex 3 applications.

Cost-Based Oracle Fundamentals

Posted by IDM under Database

Book Description
The question, “Why isn’t Oracle using my index?” must be one of the most popular (or perhaps unpopular) questions ever asked on the Oracle help forums. You’ve picked exactly the right columns, you’ve got them in the ideal order, you’ve computed statistics, you’ve checked for null columns&emdash;and the optimizer flatly refuses to use your index unless you hint it. What could possibly be going wrong?

If you’ve suffered the frustration of watching the optimizer do something completely bizarre when the best execution plan is totally obvious, or spent hours or days trying to make the optimizer do what you want it to do, then this is the book you need. You’ll come to know how the optimizer “thinks,” understand why it makes mistakes, and recognize the data patterns that make it go awry. With this information at your fingertips, you will save an enormous amount of time on designing and trouble-shooting your SQL.
