EntityDAC is an ORM for Delphi with LINQ support. It provides a powerful framework that allows performing object-relational mapping of database objects to Delphi classes with full support for encapsulation, inheritance, polymorphism and other OOP features. AdvantagesDatabase-First, Model-First & Code-First developmentThere are several approaches to database application development. Database-First – a database is developed first, then a data model and application classes are generated on the basis of the existing database. Model-First – a data model is developed first in a model developer tool, then a database and application classes are generated by this model. Code-First – in this case, application classes are the original source, on the basis of which a database can be generated, as well as a model, if necessary. When developing applications using EntityDAC, you will be able to use all the three ways. Visual ORM Model Designer with Code generationEntity Developer allows you to create and edit ORM models visually, without typing a line of XML code or manual describing class attributes in Delphi code. It supports creation of all kinds of mapping, such as table splitting, mapping entity to several tables, complex types, inheritance hierarchies, etc. Code generation is very flexible due to using T4-like templates, allowing virtually anything you may want for code generation, and you may even create your own templates for other programming languages. LINQ queriesUsing ORM when developing your applications must not only accelerate development of the application itself, but also unify the application code and make applications independent of the specifics and syntax of the SQL database for which it is developed, that will allow to support multiple databases in your application with no effort. Therefore, Language Integrated Query (LINQ) is used in EntityDAC as a query language. Using LINQ also significantly simplifies writing and further support of queries, since, at this, the Code completion Delphi engine is used when typing LINQ keywords, class names, their attributes, etc. And in the same way, LINQ queries syntax check is performed at the stage of application compilation.
