Product Description
It is nearly impossible today to write enterprise software withoutthe use of one or more relational databases. Granted, there are caseswhen the data is transient and not stored in a database, but for themost part, software needs to consume and manipulate data in a database.It sounds easy, but there are hundreds of ways to connect softwaresystems to databases and thousands of people who think they have theskeleton key for data access layers. Pro LINQ Object Relational Mapping in C# 2008 explains an efficient, repeatable way to apply industry design patterns to build scalable object–oriented data access layers.
Object relational mapping (OR/M) has been a gray area in Microsoftdevelopment for many years. It’s not that Microsoft language developersdon’t understand OR/M; in fact, the opposite is true, as is exemplifiedby the glut of third–party .NET OR/M tools on the market. The strugglehas come more from the lack of native tools with the object–orientedand object persistence capacity to effectively work in this arena. Withthe inception of .NET, Microsoft overcame the first obstacle bydeveloping an object–oriented environment and framework. The secondobstacle, the native object persistence layer, is only now beingrealized with the introduction of Language Integrated Query (LINQ) andLINQ’s children, the Language Integrated Query for Relational Databases(LINQ to SQL) and the Language Integrated Query for the ADO.NET EntityFramework (LINQ to Entities). The gray area no longer exists, and the.NET developers of the world finally have the native tools required tobuild modular, reusable data access layers.
What you’ll learnThe powerful advantages that OR/M can bring to your codeThe native tools that are now available within Visual Studio 2008 for OR/MHow to build scalable object–oriented data access layers that take advantage of OR/M’s flexibilityHow LINQ fits into this picture, together with the advantages and disadvantages that it can bringHow the concepts work in the real world by examining a fully workedand detailed case study, created with an architecture than can beeasily applied to a wide range of other situationsWho is this book for?This book is intended for Microsoft .NET developers who are using orevaluating Microsoft Visual Studio 2008 to build data–awareapplications, and it will provide patterns and resources that can beused to build enterprise class software.
