Abstract: PROBLEM TO BE SOLVED: To obtain consistency on another system including a transaction manager by deciding how alterations of basic data affect the values of one or more hybrid objects. SOLUTION: A client 90 communicates a request to a server 100 through a network 95. The server 100 maintains and uses a cache 2 to improve performance and decreases the CPU time complying with the request of the client 90. At least part of the basic data which can or can not be cached is discriminated. At least part of the basic data is mapped to one or more hybrid objects having single or multiple data dependency on at least part of the basic data. Thus, it can be decided how modifications of the basic data affect the values of one or more hybrid objects.

Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for generating a complicated web page for improving the flexibility and performance of web page design in comparison with a conventional method for processing the entire web page as a single logic entity. SOLUTION: This method for constructing and disclosing plural objects is provided with a step for providing plural fractions, a step for constructing an object from the plural fractions, a step for delaying the disclosure of at least one object containing at least one fraction belonging to a first class to examine contents and a step for disclosing at least one object containing at least one fraction belonging to a second class without examining contents.

Abstract: A determination can be made of how changes to underlying data affect the value of objects. Examples of applications include: caching dynamic Web pages; client-server applications whereby a server sending objects (which are changing all the time) to multiple clients can track which versions are sent to which clients and how obsolete the versions are; and any situation where it is necessary to maintain and uniquely identify several versions of objects, update obsolete objects, quantitatively assess how different two versions of the same object are, and/or maintain consistency among a set of objects. A directed graph, called an object dependence graph, may be used to represent the data dependencies between objects. Another aspect is constructing and maintaining objects to associate changes in remote data with cached objects. If data in a remote data source changes, database change notifications are used to "trigger" a dynamic rebuild of associated objects. Thus, obsolete objects can be dynamically replaced with fresh objects. The objects can be complex objects, such as dynamic Web pages or compound-complex objects, and the data can be underlying data in a database. The update can include either: storing a new version of the object in the cache; or deleting an object from the cache. Caches on multiple servers can also be synchronized with the data in a single common database. Updated information, whether new pages or delete orders, can be broadcast to a set of server nodes, permitting many systems to simultaneously benefit from the advantages of prefetching and providing a high degree of scaleability.

Abstract: Procedure has the following steps: supply of at least one web page fragment, determination of an order of web page or object assembly based on a relation (hypertext link) between the object and the fragment and construction of a number of web pages or objects based on the order of object or web page assembly and on any included relations (hypertext links). The invention also relates to software for ensuring all the object and fragment links are up to date. An Independent claim is made for a system for continuous updating and publication of web pages.
