Firebird .NET Data Provider is an ADO.NET data provider for Firebird. Firebird .NET Data Provider is written in C# and provides a high-performance native implementation of the Firebird API. It also includes an implementation of the Firebird Services API and Firebird array datatype support.

Firebird is a relational database offering many ANSI SQL standard features that runs on Linux, Windows, and a variety of Unix platforms. Firebird offers excellent concurrency, high performance, and powerful language support for stored procedures and triggers. It has been used in production systems, under a variety of names since 1981.

Firebird is a commercially independent project of C and C++ programmers, technical advisors and supporters developing and enhancing a multi-platform relational database management system based on the source code released by Inprise Corp (now known as Borland Software Corp) on 25 July, 2000 under the InterBase Public License v.1.0

iBATIS project provides a very simple and flexible means of moving data between your Java and .NET objects and a relationaldatabase. Use the full power of real SQL without a single line of JDBC or ADO.NET code!

The Data Mapper framework (a.k.a. SQL Maps) will help to significantly reduce the amount of Java and .NET code that is normally neededto access a relational database. This framework maps classes to SQL statements using a very simple XML descriptor. Simplicity is the biggest advantage of iBATIS over other frameworks and object relational mapping tools.

To use iBATIS you need only be familiar with your own application domain objects (basic JavaBeans or .NET classes), XML, and SQL. There is very little else to learn. There is no complex scheme required to join tables or execute complex queries. Using iBATIS you have the full power of real SQL at your fingertips. The iBATIS Data Mapper framework can map nearly any database to any object model and is very tolerant of legacy designs, or even bad designs. This is all achieved without special database tables, peer objects or code generation.

iBATIS Data Access Objects

iBATIS Data Access Objects is an abstraction layer that hides the details of your persistence solution and provides a common API to therest of your application.
When developing robust Java and .NET applications, it is often a good idea to isolate the specifics of your persistence implementationbehind a common API. Data Access Objects allow you to create simple components that provide access to your data withoutrevealing the specifics of the implementation to the rest of your application.

Using DAOs you can allow your application tobe dynamically configured to use different persistence mechanisms. If you have a complex application with a number of differentdatabases and persistence approaches involved, DAOs can help you create a consistent API for the rest of your application.

For Java users, the Data Access Objects framework is bundled as part of the iBATIS Database Layer, which includes the SQL Maps Framework. Although packaged together, the DAO Framework is completely independent and can be used without SQL Maps. .NET users can download the DataAccess framework seperately from the DataMapper framework.

C# School Ebook is a 330 page ebook that covers the .NET framework and the C# language. Starting with the basics of the language, it goes on to cover object oriented programming techniques and a wide range of C# languages features including interfaces, exceptions and delegates.

Later chapters cover practical topics including database access with ADO.NET, building Windows forms applications, multi-threading and asynchronous I/O. The final chapter covers new features in C# 2.0, including generics.
