jdbc trial software / shareware for linux

DB Visual ARCHITECT (DB-VA) offers software developers an excellent solution for database applications development. DB Visual ARCHITECT is an Object-Relational Mapping tool which provides an easy-to-use environment bridging between object model, data model and relational database.
DB-VA not only empowers you the visual modeling capability for performing both logical and physical data design, but also automates the roundtrip mapping between object model and data model.
Developers save enormous amounts of time using DB-VA to manage the coding of SQL and JDBC transparently with Plain Old Java Objects (POJO), as DB Visual ARCHITECT empowers software designers to perform roundtrip engineering of a relational database into a Class Diagram, and to an Entity Relationship Diagram and vise versa. Likewise designers can also create a database from entity relational models or class models visually on the fly.
DB-VA also generates a cost-effective, reliable, scalable and high-performance object to relational mapping layer. The generated mapping layer includes the support of transaction, cache and other optimized features. DB-VA increases the productivity and significantly reduces the risks of developing the relational mapping layer manually.
Main features:
Automate the Mapping Between Java Objects to RDBMS Tables
DB Visual ARCHITECT helps mapping between Java objects to relational database. This act not only preserves the data, but also the state, foreign/primary key mapping, difference in data type and business logic. Developers are no longer necessary to handle those tedious tasks.
Re-engineering Application Based on Legacy Database
DB Visual ARCHITECT allows you to reverse database (DB Reverse) tables through JDBC into UML models. You can form Class Diagram from the reversed models and redesign the legacy database without pain.
Multiple Database Support
DB Visual ARCHITECT promote easy migration between databases by enabling the same set of ORM Java objects to serve different databases. Besides, the tool help transforming proprietary data-type into one that suit the default database which is specified by user.
Well Proven Visual Modeling Technology
DB Visual ARCHITECT inherits the visual modeling environment from Visual Paradigm for UML, a well-known UML CASE Tool that provides intuitive inline editing for both Class Diagram and ERD. This truly what-you-see-is-what-you-get diagram editing facility reduces the effort and time in design the system.
Enhancements:
- Branch and tag capabilities were added to the VP Teamwork Server, including Subversion and CVS repository integration.
- This allows different modeling projects to be run in parallel while keeping the release quality project stable in the trunk.
- There were also a number of enhancements for various other features.

- Performance Evaluation - Offers a number of procedures for accessing the return and risk adjusted return (Treynors Measure, Sharpes Ratio).
- GUI Bundle - we bundle a suite of graphical user interface JavaBean components allowing the developer to plug-in a wide range of GUI functionality (including charts/graphs) into their client applications.
- JDBC Mediator - A J2SE Component which mediates between a J2SE component, its J2SE Clients and the Database server. The JDBC Mediator J2SE classes are a convenient way of enhancing all financial and mathematical specific methods with JDBC-based functionality. Check the jdbc subpackage of every J2SE class for JavaDocs documentation.
- Web Application Example - A Java WAR file which contains a JSP example that makes use of the functionality provided by our J2SE Component.
- Synthetic JDBC - The JDBC functionality provided by the Web Application example included within this package. This Web Application is an example of how to make a JSP client using our J2SE Component while manually implementing the JDBC code. The JSP Application applies J2SE methods to certain rows from the database and lists the output in HTML format.
