An information server is an integrated software platform consisting of a set of core functional modules that enables organizations to integrate data from disparate sources and deliver trusted and complete information, at the time it is required and in the format it is needed. Similar to how an application server is a software engine that delivers applications to client computers, an information server delivers consistent information to consuming applications, business processes and portals. Example: (voaaya.com ) ==Architecture overview== An information server application can be considered in three logical tiers: a platform foundation, a layer of information oriented services, and a series of optional modules.() Viewed in this construct, an information server looks like this: Optional components : *Understand — data profiling and metadata creation to understand the content, quality, and structure of information as it resides in source systems : *Cleanse – data quality procedures to eliminate duplicate information, match common records, standardize formats and survive the best information forward : *Transform – extract, transform and load (ETL) information from any data source (structured, unstructured, mainframe or application) to another : *Deliver – data federation capabilities to view and manipulate data from a collection of resources as if they were a single resource while retaining their autonomy and integrity. Services layer : *Parallel processing : *Metadata management : *Administration and reporting : *Service deployment (for SOA utilization) : *Connectivity Platform foundation : *Application server : *Relational database When fully leveraged on a single platform, the optional components and shared platform services clearly differentiate an information server from other traditional data integration technologies due to its holistic approach to information integration. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Information server」の詳細全文を読む スポンサード リンク
