Pro ODP.NET for Oracle Database 11g

This book is a comprehensive and easy-to-understand guide for using the Oracle Data Provider (ODP) version 11g on the .NET Framework. It also outlines the core GoF (Gang of Four) design patterns and coding techniques employed to build and deploy high-impact mission-critical applications using advanced Oracle database features through the ODP.NET provider.

The book details the features of the ODP.NET provider in two main sections: "Basic," covering the basics and mechanisms for data access via ODP.NET; and "Advanced,' covering advanced Oracle features such as globalization, savepoints, distributed transactions and how to call them via ODP.NET, advanced queueing (AQ), and promotable transactions. It takes you from the ground up through different implementation scenarios via a rich collection of C# code samples.

It outlines database security and performance optimization tricks and techniques on ODP.NET that conform to best practices and adaptable design. Different GoF design patterns are highlighted for different types of ODP.NET usage scenarios with consideration of performance and security.

It provides a comprehensive guide to the synergistic integration of Oracle and Microsoft technologies such as the Oracle Developer Tools for Visual Studio (11.1.0.7.10). It also details how programmers can make use of ODT to streamline the creation of robust ODP.NET applications from within the Visual Studio environment.

Résumé
In this chapter, you've taken a look at some of the various ways you can use to connect to an Oracle database via ODP.NET: TNS connections Connections without using TNSNames.ora Oracle's EZConnect You've also seen how you can use various connection string parameters to implement connection pooling, integrated Windows authentication, and connections with special privileges. Last, we covered the basic groundwork on TAF and its limitations and how you can ultimately enable it in your application. In the next chapter, you will take a step further and write code to transact with the Oracle database. 67 C H A P T E R 4 Retrieving and Manipulating Data with ODP.NET I was once told during a technical workshop filled with geeky programmers that an enterprise application is only as strong as its data tier. The programmers loved catchy phrases like that. I'm not sure how true that rings, but I can definitely agree with the most of them that if you don't know your database well enough, you're going to build underperforming routines that the remaining 70 percent of your application will unfortunately be based on.
