摘要： A system for identifying a parameter in a version of a data entity created at a specific time, wherein at a first time the version is an active version and at a second time the version is a previous version, the system comprising: a database for storing the plurality of versions of the data entity as they are created; a cache for storing the first active version of the data entity; wherein when a new version of the data entity is created by updating at least one parameter of the data entity, a new active version replaces the first active version stored in a cache and the first active version becomes a previous version stored in the cache; and wherein the new active version includes a list of the or each previous version of the data entity with an associated time at which the version was an active version, such that by identifying the version of the data entity which was active at the specific time the parameter is determined.

摘要： A method and a system for maintaining coherence of cache contents in a multi-tiered architecture of servers are described. This includes a front tier of satellite servers, each operating a local cache, and a middle tier of central servers each operating a central cache. Central servers interface with databases through database servers to retrieve the data elements used to construct objects and store them in central caches. Once constructed, objects are attributed a time-to-live (TTL) and stored in central caches then, forwarded to the satellite servers where they are stored in local caches before being delivered to the software applications that have requested them. They are invalidated when outdated and reconstructed from a central server from where they are forwarded to all central caches and to the local caches where they are needed.

摘要： The invention relates to a system for reserving travel products, comprising a central computer system which is used to process user requests. Moreover, the central computer system, which can be accessed from at least one user terminal, comprises means for calculating sales price information relating to travel products and for returning said information to the user. According to the invention, the reservation system comprises: a database containing determination rules which are used to associate each travel tariff with a tariff group; and a search engine which is used to search for products that meet the criteria entered as part of a user request and the associated tariffs. The search engine communicates with the database in order to access the aforementioned determination rules and to apply same to the travel products that meet the input criteria, such as to return and display a response at the user terminal, which contains information relating to the products that meet the input criteria, said information being sorted according to tariff group. The invention also relates to a processing method for the reservation system. The invention is suitable for computer reservation systems that search for low fares.
