A system and method to program computers directly from a Web Browser, by cascading sets of retrieval, computation and update requirement specifications to facilitate repetition, decision and execution control logics, without using query, procedural and programming languages. This method provides database product independent Web based access of databases on the Internet with the following capabilities: creating a database dictionary/directory for describing existing or new databases, tables, columns, and data values; creating new databases; searching the directory by keywords to establish entry points to the directory; browsing the directory upward or downward by the user from the entry points to identify information of interest; creating retrieval, computation and update requirement specifications during the directory browsing process; saving, restoring the requirement specifications by name and submitting the requirement specifications to be executed by the computing engine; cascading previously saved requirement specifications as components and sub-components to create newly named requirement specification which can itself be saved or executed. |
