- Assign appropriate data access technologies to common data access scenarios.
This module introduces the concepts of data modeling, and in particular, Entity
Data Models (EDMs). It explains how you can use EDMs to decouple the conceptual
data structure in your applications from the logical data structure in the data
store.

This module explains how to query an entity data model by using common methods
such as LINQ to Entities, Entity SQL, and the classes in the EntityClient namespace.

This module introduces the concurrency model that the Entity Framework uses
to address the issues faced by applications that must support multiple users who
access the same data simultaneously. It also describes how the Entity Framework
can make use of transactions to ensure data integrity.
Lessons

After completing this module, students will be able to:
- Describe the optimistic concurrency model that the Entity Framework uses.
- Manage transactions in applications that use the Entity Framework.
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
- Using Design-Time Generated Entity Framework Views
- Monitoring Performance
- Performing Asynchronous Data Modifications
- Improving the Performance of Query Operations
- Improving the Performance of Update Operations
After completing this module, students will be able to:
- Explain how the Entity Framework executes queries.
- Understand the impact of tracking and object materialization on query performance.
- Describe how to use compiled queries.
- Describe how to use design-time generated views.
- Describe how to monitor query performance.
- Describe how to perform asynchronous data modifications.
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
- Using a Template to Add Custom Functionality to Entity Classes
- Creating Custom Entity Classes
After completing this module, students will be able to:
- Use partial classes and methods to add business logic to generated code.
- Create and use templates to customize code generation.
- Modify existing business classes to take advantage of entity functionality.
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
- Using POCO Classes
- Extending Your POCO Classes
After completing this module, students will be able to:
- List the requirements that their POCO classes must meet.
- Create POCO entities that support automatic lazy loading.
- Create POCO entities that support automatic change tracking.
- Describe the options for using interfaces and inheritance to create custom entity objects.
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
- Creating the Contacts and Orders Data Access Tier
- Protecting Data Access Operations
After completing this module, students will be able to:
- Describe the issues and strategies that are relevant to building n-tier applications.
- Understand the key components that they must create in order to implement an n-tier application.
- Describe how to protect operations and data in an n-tier application.
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

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.
Lessons
- Retrieving and Modifying Data by Using ADO.NET Commands
- Retrieving and Modifying Data by Using DataSets
- Managing Transactions and Concurrency in Multiuser Scenarios
- Using ADO.NET to Retrieve Read-Only Information Quickly and Perform Simple Data Modifications

- Enabling Data Modifications
After completing this module, students will be able to:
- Retrieve and update data by using ADO.NET commands and stored procedures.
- Retrieve and update data by using DataSet objects.
- Implement transactions and handle concurrency exceptions.
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.

- Design a logical data model by using LINQ to SQL.
- Manage performance by using LINQ to SQL, and handle concurrency.
