Web applications for accessing and maintaining large amounts of structured data, typically stored as records in a database management system, are called “data-intensive Web applications” (DIWA applications). In this work, the content requirements for each page of the application are specified through a view, denominated Navigation Context View (VCN). We consider that VCN’s data are stored in a relational database, which does already exist, or, otherwise, must be specifically designed for the application.
In this work we propose a process for generating and maintaining VCNs for DIWA applications. One advantage of our approach is that the implementation and maintenance of the VCNs can be done in an automatic way based on the VCNs’ conceptual specifications. We consider that the VCNs can be implemented either as object views or as XML views.
