Oracle Performance Tuning for 10gR2, Second Edition

Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25% performance increase.

Gavin Powell shows that the central theme of Oracle10gR2 Performance Tuning is four-fold: denormalize data models to fit applications; tune SQL code according to both the data model and the application in relation to scalability; create a well-proportioned physical architecture at the time of initial Oracle installation; and most important, mix skill sets to obtain the best results.

Data warehousing with MySQL, a free and popular database, has never been made easier with this step-by-step tutorial on building dimensional data warehouses.

The topic combination of VB .NET and ADO.NET is unbeatable. VB .NET is the most popular language in which to code. And, every developer needs to understand ADO.NET to allow data to be accessed from a Web site. In this book Developers will be shown numerouse code examples that will illustr4ate how to program database driven applications within the .NET Framework. The book is aimed at both established and new VB Developers. Important topics covered include: Visual Studio development environment, ASP.NET applications, Windows Forms application, using VB .NET with ADO.NET, complex queries, security, COM interop., and application deployment.

This book is for the serious developer, whether corporate or independent, who wants to create database applications using Visual Basic .NET. If you are looking for a primer on .NET or even a beginner book for Visual Basic .NET, then you would be wise to pick up another book to give you the basics on those topics. This book focuses on the topic I love best: database development.

Current Visual Basic developers will get quite a bit out of this book. Although you will find that much of Visual Basic .NET looks familiar, the language has grown up quite a bit and even gets more of the respect it deserves since we can now use the Visual Basic we know and love in Web Forms as well as Windows Forms. Those who are familiar with ADO will appreciate the samples that show how to use ADO.NET. Hopefully, even hard-core Visual Basic developers will appreciate the chapter on wrapping up some of the ADO.NET data access into classes for simplified coding.
