Web Database Objects

Web Database Objects (WDO) is an automation technology for rapid development of Web enabled online transaction processing applications based on Java and Oracle. The key benefits of WDO are: 1) a dramatically shortened development cycle and time-to-market with no compromise to functionality or performance; 2) dramatic reductions in development cost; and 3) dramatic reductions in cost of ownership and operations costs.

WDO provides the following capabilities:

1) automation based on a high level XML vocabulary;

2) an effective elimination of the Object Relational mapping problem; and

3) targeted specifically for the Web.

Due to the use of the high level XML vocabulary, very little Java or database coding is required by application developers. Productivity improvements of 20 to 1 and greater can be achieved. WDO eliminates the Object Relational mapping problem by adopting a unique approach based on the Proxy design pattern. WDO's transaction and concurrency control models are specifically developed for the stateless Web environment. WDO provides comprehensive and automatic mechanisms for rendering the state of objects in XML to facilitate Web personalization and enterprise data interchange.

By using WDO, project risk is virtually eliminated owing to the partitioning of skill sets between Java and database developers. The framework-based approach of WDO "future proofs" applications from changing requirements and database upgrades, and allows isolated and unconstrained tuning of the database design and SQL code and utilization of new database features. A low cost of ownership is achieved with WDO due to the short development cycle and the scalability of the developed applications and the WDO run time infrastructure. WDO enables the development of applications that have an ample performance safety margin and therefore ensures that there are no initial surprises and that future unanticipated performance requirements (e.g., those encountered with an Application Service Provider model) will be met.
