Lessons

  • Handling Concurrency in the Entity Framework
  • Transactional Support in the Entity Framework

Lab: Handling Multi-User Scenarios by Using Object Services

  • Handling Concurrency of Rewards Claimed Data

This module explains best practices for designing and building a scalable, optimized data access layer by using Object Services. The module introduces several techniques that can be used to optimize the performance of queries that execute against the conceptual model.

Lessons

  • The Stages of Query Execution
  • Change Tracking and Object Materialization
  • Using Compiled Queries

Module 7: Customizing Entities and Building Custom Entity Classes
This module describes how to customize and extend entities with your own business logic.

Lessons

  • Overriding Generated Classes
  • Using Templates to Customize Entities
  • Creating and Using Custom Entity Classes

Lab: Customizing Entities and Building Custom Entity Classes

  • Using a Template to Add Custom Functionality to Entity Classes
  • Creating Custom Entity Classes

Module 8: Using POCO Classes with the Entity Framework
This module introduces the ways in which you can define custom entity classes in your Entity Framework application. By default, Microsoft Visual Studio generates a set of entity classes for you from the Entity Data Model (EDM). Instead of these generated classes, you may want to use an existing set of "plain old" CLR objects (POCO) business classes in your application You can also extend the generated entity classes to add custom business functionality to your entity objects.

Lessons

  • Requirements for POCO Classes
  • POCO Classes and Lazy Loading
  • POCO Classes and Change Tracking
  • Extending Entity Types

Lab : Using POCO Classes with the Entity Framework

  • Using POCO Classes
  • Extending Your POCO Classes

Module 9: Building an N-Tier Solution by Using the Entity Framework
This module explains how to address the architectural issues that can arise when building an N-Tier enterprise application by using the Entity Framework.

Lessons

  • Designing an N-Tier Solution
  • Defining Operations and Implementing Data Transport Structures
  • Protecting Data and Operations

Lab: Building an N-Tier Solution by Using the Entity Framework

  • Creating the Contacts and Orders Data Access Tier
  • Protecting Data Access Operations

Module 10: Handling Updates in an N-Tier Solution by Using the Entity Framework
This module describes how you can handle data modifications in an n-tier solution. The module describes the different strategies for handling modifications that you should use for the different alternative formats for transporting data between tiers: data transfer objects (DTOs), self-tracking entities (STEs), and simple entities (SEs). The module also describes how to manage the exceptions that can occur during the data modification process.

Lessons

  • Tracking Entities and Persisting Changes
  • Managing Exceptions in an N-Tier Solution

  • Using the Sync Framework

Lab: Building Occasionally Connected Solutions

  • Modifying the Orders Application to Use Offline XML Data
  • Modifying the Orders Application to Synchronize Locally Cached Data

Module 12: Querying Data by Using WCF Data Services
Windows Communication Foundation (WCF) Data Services enable you to create highly flexible data services that can be used to provide access to data across the Internet or a corporate network. You can access these services by using REST-style URIs, and they can be easily consumed by a wide variety of applications. As WCF Data Services are build on top of standard Internet protocols such as HTTP and the Atom Publishing Protocol, they are an ideal choice for delivering data to AJAX applications and Rich Interactive Applications built using technologies such as Microsoft Silverlight.

  • Preventing Unauthorized Updates and Improving Performance
  • Using WCF Data Services with Nonrelational Data

Module 14: Using ADO.NET
ADO.NET is a highly flexible framework for building applications that require access to data held in a data source. This module introduces ADO.NET and explains how you can use it to develop scalable, high-performance, data-driven applications.

  • Retrieving and Modifying Data by Using ADO.NET Commands
  • Retrieving and Modifying Data by Using DataSets
  • Managing Transactions and Concurrency in Multiuser Scenarios

Lab: Using ADO.NET

  • Using ADO.NET to Retrieve Read-Only Information Quickly and Perform Simple Data Modifications
  • Developing the Product List Web Application
  • Enabling Data Modifications

Module 15: Using LINQ to SQL
ADO.NET provides a mechanism that enables you to build applications that can query and maintain data that is held in a variety of sources in a database-agnostic manner. However, building applications by using ADO.NET requires that you are familiar with the Structured Query Language (SQL) language and features of the database management system that you are connecting to. Language-Integrated Query (LINQ) to SQL provides a higher-level abstraction for managing data that is held in a Microsoft SQL Server database, and is an ideal stepping stone for migrating ADO.NET applications toward the ADO.NET Entity Framework. This module introduces LINQ to SQL and explains how you can use it to abstract the low-level details of ADO.NET queries by developing against a logical data model.
