One-Stop Object-Relational Solution
Tutorial Details:
As everyone knows software applications require to be updating and enhancing with respect to the changes in user requirements from time to time, thus software development has to be able to anticipate for changes in order to meet the user's requirements in the long run. Even if there is a very simple change required to be made for a database application, the developers still find it a tedious job to ensure the consistence among the database schema, application and the persistence layer. The changing requirements of a database application and/or its schema could generate a huge load of repetitive work for the developers, if they are still using the conventional manual database mapping procedures between the SQL, programming language and object database connectors such as OCDC and JDBC.
DB Visual ARCHITECT (DB-VA) provides an alternative way to develop the database application. DB-VA not only empowers software developers the visual modeling capability for performing logical and physical data designs, but also automates the synchronization process among persistent code, object model, data model and relational database by mapping, which in turn significantly reduces the risks of developing the persistence layer manually and increases the developers' productivity.
Generate Complete Persistent Model by drawing Class Diagram
DB-VA offers software developers a visual modeling environment to model the pure object oriented systems by using the class diagram with the latest UML 2.0 notation. We need to face the reality that our object oriented applications need to be interfaced with a widely used relational database. Based on the object model defined in the class diagram, DB-VA supports the generation of persistent model together with a persistence layer. You can use the generated persistent model to access and manipulate the database instead of using SQL statements through object database connects such as ODBC and JDBC. Through visual data modeling, developers can significantly shortens the development time and increases productivity for database applications development. Furthermore the pure object oriented application architecture will not be distorted by the mapping between OO and relational database paradigms.
