Map your objects to your relational data. Vanatec OpenAccess has been designed for bridging the gap between object-oriented programming and relational data management and access based on the .NET framework. Tightly integrated into Microsoft Visual Studio, OpenAccess saves 30% coding efforts and provides Object Relational mapping (O/R mapping, O/RM, ORM) features like transparent persistence, reverse mapping, database independence and disconnected data support. The only limitation of the Vanatec OpenAccess Express is the restriction of supported database to Microsoft SQL Server 2005 Express, Oracle Express and MySQL running on the local machine. Vanatec OpenAccess Express allows free, fully functional Object-relational Mapping with free Database editions.

Object-relational Mapping for .NET

The usual DataSet in .NET applications creates problems for developers who want to use the full power of object-oriented programming to solve their business problems. Using business objects to organize the behavior they are calling on a proven approach.

However this architectural approach is difficult to reconcile with DataSet’s rigid row and column structure. Instead of DataSet, use Vanatec’s object-relational mapping to transparently map between your business objects and your relational tables.

With Vanatec OpenAccess, you’ll find all of the O/R mapping essentials built right in: transparent persistence, database flexibility and database independence, reverse mapping, disconnected data support. And most importantly, it separates the storage details from your object model, simplifying your code and boosting productivity.

Transparent Persistence
Vanatec OpenAccess is an object-relational mapping persistence framework that offers transparent persistence through post-compilation code enhancement. As such, adding persistence functionality is non-intrusive to the object model. Custom attributes are used to assign attributes to classes. With custom attributes classes can be declared as persistent, and for example indexes can be defined for class fields. With Vanatec OpenAccess, classes do not have to inherit from a specific base class or implement a specific interface to be persistent. Vanatec OpenAccess does not put any restrictions on the object model and supports inheritance, interfaces and .NET Framework collections.

Database Flexibility & Database Independence
You don’t live in a vacuum, and neither will your .NET application. Using Vanatec OpenAccess, your application easily runs with various database branches, various table layouts, or even various database technologies. Only one single file needs to be edited.

Connecting your .NET application to different databases is easy in part because Vanatec OpenAccess separates the storage details from your object model. That simplifies your code and boosts productivity on the one hand. On the other, it means more flexibility: Working with various databases, changes in the table layout or data model don‘t cause changes in the object model and vice versa.

Reverse Mapping with Legacy Databases
Vanatec OpenAccess detects your existing legacy data model the moment you connect it, creates object models, and even lets you edit the object model exactly how you want it.

The reverse mapping experience begins the minute you connect your Visual Studio project to the legacy database using the Reverse Mapping wizard. Like magic, Vanatec OpenAccess recognizes the data model and creates an object model. Then you can start developing your new .NET application.

Disconnected Data Support
Whether you’re thinking of mobile devices, Web applications, or replications, you need disconnected data management you can count on anywhere, anytime. In these cases, it isn’t possible to maintain a database connection for the duration of a transaction. For this situation, Vanatec OpenAccess offers ObjectContainer. It frees objects from databases and uses optimistic transactions. It tracks which objects have been changed or are new. A callback lets you resolve any conflict.

Tight Integration with Microsoft Visual Studio
Using Vanatec OpenAccess is easy in part because you can continue using the same application you already know - Microsoft Visual Studio. And when it comes to data access, simply choose OpenAccess in the Visual Studio menu. Fully integrated into Visual Studio, Vanatec OpenAccess takes action on the data access and it gives you the programming productivity you need to develop sophisticated applications in no time.
