Techniques, systems, apparatus and computer-program products are disclosed for developing a web-hosted shared database system with improved user interface and reduced programming. In one aspect, using a web application development framework includes declaratively specifying a web application's pages using page configurations. The framework can automatically coordinate page state with the state of a database server and an applications server, so that the specified page is first rendered and then one or more portions of the page can be updated in response to a server data change, Also, programs that are executed when a request is issued are declaratively specified using program configurations. Either or both of the page configurations and the program configurations can be implemented by access to a unified application state virtual database. Further, the unified application state virtual database can include the persistent database of the application and transient memory-based data, such as session and page data.

Web application development framework

Techniques, apparatuses, and systems for application design and application data flow analysis. Techniques, apparatuses, and systems can include providing a design interface to create an application with different user groups and access rights, the design interface operable to specify an action to include to a page of the application, where the action, when invoked, modifies the application state; receiving an action specification that describes an access rights modification that results from an invocation of the action during an execution of the application, where the access rights modification indicates an enabling or disabling of one or more access rights of a user; and generating application specification queries and commands to enforce access rights based on the access rights modification.

Application design and data flow analysis

In general, a technique or mechanism is provided to efficiently transfer data of a distributed file system to a parallel database management system using an algorithm that avoids or reduces sending of blocks of files across computer nodes on which the parallel database management system is implemented.
