ADO.NET, ADO.NET Entity Framework and LINQ

ADO.NET is the standard data access library built in .NET Framework used by developers to access and modify data stored in relational database systems, call stored procedures and access non-relational data sources like XML.

LINQ (Language Integrated Query) is extension to C# and other .NET languages that adds native querying syntax directly into the language and thus simplifies querying data and dramatically reduces the amount of code.

ADO.NET Entity Framework is new paradigm for developing database applications. It allows developers to focus on data through an object model instead of through a logical/relational data model. It abstracts the logical database structure using a conceptual layer, a mapping layer, and a logical layer and provides support for LINQ to simplify querying.

Java Persistence API and Hibernate

Java Persistence API (JPA) is a Java framework based on the concept of object-relational mapping (ORM) that allows developers to manage relational data in Java SE and Java EE platforms. JPA defines persistent entities as lightweight Java classes that are mapped to the database tables. Entities typically have relationships with other entities, and these relationships can be specified directly in the entity class by using annotations, or in a separate XML descriptor. Once the mapping between classes and tables is defined, the persistent entities can be loaded, modified, persisted, deleted and queried by simple API.

Hibernate is a powerful, high performance object/relational persistence framework, very popular among the Java developer community. By concept it is very similar to JPA and provides mapping objects to tables, querying and manipulating persistent objects.

Teams

Three teams take part in the event:

  • ­The .NET Team (Branimir Giurov, Stefan Dobrev, Deyan Varchev, Galin Iliev and Dimiter Kapitanov) – stands up for ADO.NET Entity Framework and LINQ
  • ­The Java Team (Miroslav Nachev, Martin Valkanov, Peter Milev, Svetoslav Kapralov and Vesko Arnaudov) – stands up for Java Persistence API and Hibernate
  • The Referees Team (Svetlin Nakov, Nikolay Todorov and Stanimir Boychev) – technologically neutral, moderate the discussion
