Re: Servlet and Oracle WebDB

Title: RE: Servlet and Oracle WebDB

You have to understand the model for developing for WebDB.  WebDB is a 4GL tool.  It does not allow much room for component customization.  Also, any component customization that you do has to be done in PL/SQL (yes, you can write stored procedures in Java, but you would still need to wrap them in PL/SQL).  If you are willing to do your development in PL/SQL and do not mind the severe limitations of a browser-based 4GL like WebDB, then it will probably be very useful for you.

 

Also, WebDB is not 3-tier, it is client-server.  It runs entirely in the database with just a mini HTTP adaptor running the middle.  However, all of your presentation logic AND application logic resides COMPLETELY in the database.  The design of WebDB is for rapid development of simple applications totally bound to Oracle relational data.  It was originally developed by Oracle consultants to aid them in developing browser applications for Oracle.  If you do not mind the limitations of WebDB, and your applications are not that complex, it might work well for you.

 

Otherwise, start investigating Oracle Application Server 4.08 and the new JDeveloper 2.0.  Oracle AppServer is n-tier and has a very robust, scalable architecture that is not completely dependent on the database like WebDB.  WebDB is completely dependent on the power of your database server.  If you have enough processes to allocate to running WebDB along with anything else Oracle that you do, then it might work for you.  Just realize it is limited, and you better really like PL/SQL.

 

Later,

Chris

Cezar,
I don't think they support for anyother Database but  currently we need to use  Oracle as our database.
I need to find is there any drawback for using Oracle Web DB instead of Servlet??
