MOC 10265, Developing Data Access Solutions with Microsoft Visual Studio 2010

Goals

• Evaluate a variety of business cases, and then select an appropriate combination of data access technologies and tools most appropriate to each case. Describe the roles of Entity Framework, WCF Data Services, and ADO.NET for building and maintaining applications. Use LINQ on top of these technologies to improve productivity and the quality of their applications.
• Learn to use the tools provided with the Entity Framework to map the conceptual model used by the business logic of an application to the logical data model provided by a database.
• Learn to query an Entity Data Model (EDM) by using common methods such as LINQ to Entities, Entity SQL, and the classes in the EntityClient namespace.
• Learn to perform data modification tasks on data in an EDM.
• Learn to explain the function of the Object Services model implemented by the Entity Framework and the support provided by the Object Services API for addressing the issues faced by enterprise applications that have to handle multiple concurrent users simultaneously accessing the same data .
• Learn to describe best practices for designing and building a scalable, optimized data access layer by using Object Services.
• Learn to customize and extend entities with their own business logic and use advanced mappings to shape the data model to their business and application requirements.
• Learn to reuse existing business classes in a data access layer built by using the Entity Framework.
• Learn to address the architectural issues that can arise when building an n-tier enterprise application by using the Entity Framework.
• Learn to build extensible solutions that can update data in an n-tier enterprise application by using the Entity Framework.
• Learn to access offline data or data that that has limited availability in client applications.
• Learn to design, develop, and consume a simple WCF Data Service.
• Learn to use WCF Data Services to update and delete data and to handle multi-user concerns.
• Learn to develop high performance, scalable ADO.NET applications that can query and update data.
• Learn to explain how LINQ to SQL enables development against a logical model which abstracts the low-level details of querying ADO.NET tables and result sets.
