Database caching

Database caching is a process included in the design of computer applications which generate web pages on-demand (dynamically) by accessing backend databases.
When these applications are deployed on multi-tier environments that involve browser-based clients, web application servers and backend databases, middle-tier database caching is used to achieve high scalability and performance.
In a <a href="/facts/Three_tier_architecture/cUTM2sU9">three tier architecture</a>, the <a href="/facts/Application_software/YQuj7Kog">application software</a> tier and <a href="/facts/Computer_data_storage/wPHKFpdx">data storage</a> tier can be in different hosts. Throughput of an application can be limited by the <a href="/facts/Computer_network/3w5RM99p">network</a> speed. This limitation can be minimized by having the <a href="/facts/Database/VYcpkevb">database</a> at the application tier. Because commercial database software makes extensive use of system resources, it is not always practical to have the application and the <a href="/facts/Database/VYcpkevb">database</a> at the same host. In this case, a more light-weight database application can be used to cache data from the commercial <a href="/facts/Database_management_system/VYcpkevb">database management system</a>.
