....in software architecture [8] and reconfiguration of software architectures [1] 12] as discovered by this author, there is not much research towards web to database architectures. The Zelig project introduces a schema that can be coupled with HTML to control various CGI based database executables [13]. The main difference is that the Zelig project appears to tightly couple the interface with the database by hard coding entire query strings in the HTML documents. The CRS architecture extends this approach by incorporating intelligent query building knowledge in the middle level components. The ....

....by data miner applications. In general a lightweight database is equally accessible to client or server side processing, which means that processing may occur wherever is most efficient or most convenient. Related Work Integrated Relational Databases As mentioned above, several authors (e.g. [Varela94]) have reported integrating database engines to WWW. A typical example is a site s telephone directory, which is accessed using a CGI script interfacing to a relational database engine such as Ingres. We see the present work as being complementary to these efforts. A lightweight database will ....

....the interface maintanence. Whenever the interface needs to be changed, the source code will have to be modified and recompiled. One approach to solve this problem is to separate the interface displays and data operations from the source code. This topic has been addressed by a number of researcher [10] and several prototype systems are available in the public domain, such as GSQL, available at http: www.ncsa.uiuc.edu SDG People jason pub gsql starthere.html and WDB, at http: arch http.hq.eso.org brasmus wdb These systems allow application developers freedom to define the Web forms and ....

....transmission back to the user. The page is virtual in the sense that it has been created in response to the request rather than simply being retrieved (figure 1) although from the user s perspective it appears that a page has been retrieved as usual. Most gateways are thus transparent to the user[7]. This is both a strength and a weakness: it allows users to access seamlessly other information sources through WWW, but may provide only limited access to the underlying RDBMS by permitting only limited number of pre defined (and invisible) queries. Moreover it enforces a division of work ....
