Abstract: Improvements in the creation, maintenance and management of web based information are provided. A development environment conducive to separation of tasks and data, works in combination with the means to present views of changed information for approval to users. Data from file systems and database systems can be combined to create a rich source of material for users, while changes to such material can be effectively controlled and released for production.

Abstract: Embodiments of the present invention is directed to a data structure in conformance with a database schema for accessing and managing content managed data and to a system, a method and a computer program product for creating the database schema. According to one embodiment of the invention, a method for creating a database schema for accessing and managing content managed data comprising the steps of: creating a base schema; creating a write schema; and creating a read schema; the database schema used by a business logic application to access and manipulate the content managed data in the database. Embodiment of the present invention manages changes to the data using the write schema and the read schema rather than by using a modified base schema.

Abstract: A data processing system-implemented method, system and article of manufacture for differential schema migration. A differential schema migration system can include a schema extractor configured both to extract a contemporary schema and corresponding contemporary data from a first connected database and also to generate an intermediately formatted form of the contemporary schema and corresponding contemporary data. The system also can include a schema update user interface configured to facilitate applying changes to the intermediately formatted form of the contemporary schema and corresponding contemporary data. Finally, the system can include a schema differential migrator configured to apply changes to a second connected database based upon a comparison of an extracted schema and corresponding data from the second connected database, and a changed version of the intermediately formatted form of the contemporary schema and corresponding contemporary data.

Abstract: An information handling system comprises an input for receiving a spreadsheet application in static HTML form; a compiler for compiling the spreadsheet application to produce a generic XML document; an interpreter for interpreting the XML document to produce a browser-specific hypertext document representing the spreadsheet; and an output for serving the hypertext document to a client.

Abstract: A computer system defines a set of electronic catalogs. The catalogs each have an associated contract and each user of the catalogs is associated with a contract. The set of catalogs is represented as a graph. Nodes in the graph represent contracts, catalogs, categories, products and prices. Edges in the graph are labelled with a catalog identifier or a contract identifier. The graph is traversed to display data to the user. The traversal of the graph by a given user is constrained so that the user's contract and catalog matches the edge labelling of the traversal.
