Further you will learn about Mapping Entities and Database structure here you will see how to create mapping between objects and database structures, how to define tables and columns. You will learn the specifics or SQL Server types and how to map them to .NET Types. You will define all possible types of relationships for your database model. Next you will dive into Querying data you will learn the basics of Linq then you will start with simple queries, advance to aggregations and projection techniques. You will see how to obtain object graphs and talk about performance. Next you will learn Manipulating data, you will learn how to create, read, update and delete data, commonly referred to as CRUD operations.
