Embodiment Construction

[0088] The following detailed description of the invention refers to the accompanying drawings. While this description includes exemplary embodiments, other embodiments are possible, and modifications can be made to the described embodiments without departing from the spirit and scope of the invention.

[0089] figure 1 A data storage system 100 according to the invention is described wherein a software application 10 is independently interfacing with a database system 20 on the one hand and a cache system on the other hand which is also referred to as a cache and includes one or more cache node 30 .

[0090] It is worth noting here that the database cache system of the present invention described later is primarily ad hoc in that the entire database content can eventually be transferred to a set of cache nodes which act as a front-end process protecting all read traffic layer, otherwise the read traffic would reach the database system 20, thus drastically improving the perf...

Abstract

A method and a system of storing data by a software application are described. In a data storage system comprising one or more database systems and at least one cache node the software application interfaces independently the one or more database systems on a first dedicated interface, and the at least one cache node on a second dedicated interface. The method and system are characterized in that: each read query of the data storage system by the software application is first solely issued to the plurality of cache nodes which returns the queried data if available. If not available, the software application receives a miss that triggers a fetch of the queried data from the one or more database systems. Upon having retrieved the queried data, the software application adds the queried data to at least one cache node. The method and system are further characterized in that each writing of the one or more database systems by the software application is also concurrently performed in the at least one cache node. Hence, population of the at least one cache node is quickly done at each missed read query of the at least one cache node and at each write query of the data storage system.

Description

technical field [0001] The present invention relates generally to data management systems of the type used by large providers of goods and services to track their overall product supply and availability levels, and more particularly to a system that allows advanced queries issued by remote users of data stores Replied with no delay or with very short delay, without affecting the completion of the transaction, which is constantly updated due to the management of the data store. Background technique [0002] In all interconnected worlds, all large providers of goods and services have now established large database systems which maintain the characteristics, specifications and costs of their product and service offerings. Operating under the control of a database management system (DBMS), the content is simultaneously accessible to all online clients, possibly from all over the world. Online customers are thus provided with an opportunity to query databases and overall busines...
