  • Telerik Data Access was the only solution providing real transparent persistence and a rich set of ORM functionality combined with high performance and tight integration into Visual Studio. It saved us 60% of development time and reduced the lines of code needed for data access by 99%.

  • Telerik Data Access is phenomenal - maybe even revolutionary. It has saved me hundreds of development hours. I now no longer maintain any data access layer code. Data Access seamlessly integrates my most complex object models with SQL Server with no manual intervention. I enthusiastically recommend it for any scenario requiring persistence.

  • Since I started using Telerik Data Access, my productivity has increased, and also the value for the client. Now, I've started a development business and I'm considering buying a license for DevCraft Complete. Telerik has exceptional tools for development!
