LINQ

Devart presented EntityDAC at this year’s Coderage XII conference

Posted by on November 14th, 2017

Devart was pleased to participate in the annual online conference for Delphi developers – Coderage XII organized by the Embarcadero company and held on November 7-9, 2017.

During the session, we presented the solution how using ORM for Delphi – EntityDAC can simplify and speed-up the application development process. In our presentation, we used real samples, as well as other Devart products (UniDAC, dbForge Studio for Oracle) to clearly demonstrate this.

What is LINQ for Delphi in EntityDAC?

Posted by on October 15th, 2014

The main idea of EntityDAC, as well as any ORM for RAD Studio, is to free the programmer from having to implement a business-logic, and the logic of database interaction separately in the application source code. When writing code, programmer abstracts himself from specifics of a DBMS and operates the database entities using structures of his “native” programming language. (more…)

Using Oracle and MS SQL Server in Entity Framework applications simultaneously

Posted by on January 13th, 2011

Some of our users that are working with Entity Framework need to combine Oracle and Microsoft SQL Server in one application. Entity Framework is a powerful ORM with cross-database possibilities, so there is nothing extraordinary in this task.

However, there is a set of pitfalls and difficulties that are not obvious at first glance.

One of our users, Paul Reynolds, has made a series of posts based on his experience for multiple database support in EF:

LinqConnect and ORMBattle.NET

Posted by on August 13th, 2010

ORMBattle.NET has recently updated their results of testing various .NET Framework ORMs and added LinqConnect to their lists. LinqConnect demonstrates one of the best results it their tests.

ORMBattle.NET is an open-source project for ORM comparison, supported by a development team from X-tensive.com. This project contains a set of tests for feature-oriented comparison, but it is more focused on the performance tests (CRUD operation performance, object materialization, etc.).

LinqConnect development team agrees with most of the tests. The results on the whole are reliable enough to consider them when choosing ORM framework.

We already are studying the situations where LinqConnect showed bad results and working on performance improvement.
