Introduction
This chapter demonstrates about the LINQ overview. While working with the different technologies user can get the problems when querying the data because user need to have the more knowledge about the technologies. Following are the concepts covered in this chapter.
- Types of LINQ
- Architecture of LINQ
- Advantages of LINQ
Description
In order to get the data access from different technologies user need to use the LINQ which can get access from the different technologies. Following are the some types of LINQ are listed below.
- LINQ - SQL
- LINQ - XML
- LINQ - Datasets
- LINQ - Entities
- LINQ - Objects
Description
LINQ Consist of the 3 layered architecture in which first most layer is the language extension and last layer i.e bottom layer have the data sources to implement IEnumerable<T> or IQuerable<T> generic interfaces. The below figure demonstrates about the architecture of the LINQ.
Description
LINQ have the many advantages because of its expressiveness which enables user to express declarative and some more advantages are listed below.
- Programmer burden will decrease.
- No need to learn different Query Languages.
- Rapid Application Development(RAD) facilities are provided.
- Execution of the queries will be fastest. Because Queries are executed in the front end application only.
- Built in Security will be provided.
Points
- LINQ is a 3 layered architecture.
- LINQ maintain more accurate queries.
- LINQ is more secured.
