Linq to Objects supported Joining Data
AbstractJoins have been studied as a key operations in multiple application domains. This paper focuses on the study of joins as a first-class LINQ operators and their implementation as integrated component of the query processing. The join methods provided in the LINQ perform inner join, left outer join, and cross join. Our goal is to provide join operations, similar to SQL statements in the databases. We describe an efficient implementation of the following join operators: inner join, left outer join, right inner join, full outer join, left excluding join, right excluding join, full outer excluding join, and cross join. A simple example is used to present the potentialities of LINQ technology to solve the problem with the object-relational mapping.
