Editing Enterprise information system

{{short description|Type of information system}}
An '''Enterprise Information System''' ('''EIS''') is any kind of [[information system]] which improves the functions of enterprise business processes by integration. This means typically offering high quality of service, dealing with large volumes of [[data]] and capable of supporting some large and possibly complex [[organization]] or enterprise. An EIS must be able to be used by all parts and all levels of an enterprise.<ref name="eidvtai" />

The word ''enterprise'' can have various connotations. Frequently the term is used only to refer to very large organizations such as multi-national companies or public-sector organizations. However, the term may be used to mean virtually anything, by virtue of it having become a corporate-speak [[buzzword]].{{Citation needed|date=June 2016}}

==Purpose==
Enterprise information systems provide a technology platform that enables organizations to [[Enterprise integration|integrate]] and coordinate their [[business processes]] on a robust foundation. An EIS is currently used in conjunction with [[customer relationship management]] and [[supply chain management]] to automate business processes.<ref name="eidvtai" />  An enterprise information system provides a single system that is central to the organization that ensures information can be shared across all functional levels and management [[hierarchies]].

An EIS can be used to increase business [[productivity]] and reduce service cycles, [[product development]] cycles and marketing life cycles.<ref name="eidvtai">{{cite book |title=Enterprise Information Systems: Contemporary Trends and Issues |last=Olson |first=David L. |author2=Subodh Kesharwani |year=2010 |publisher=World Scientific |isbn=978-9814273169 |pages=2, 13–16 |url=https://books.google.com/books?id=-AwDAp7Fe2UC |access-date=20 August 2013}}</ref>  It may be used to amalgamate existing applications. Other outcomes include higher [[operational efficiency]] and cost savings.<ref name="eidvtai" />

Financial value is not usually a direct outcome from the implementation of an enterprise information system.<ref name="eiscmta">{{cite book |title=Enterprise Information Systems: Concepts, Methodologies, Tools and Applications |author=Information Resources Management Association |year=2010 |publisher=Idea Group Inc |isbn=978-1616928537 |pages=38, 43 |url=https://books.google.com/books?id=hpc6-SfS2scC |access-date=20 August 2013}}</ref>

==Design stage==
At the design stage the main characteristic of EIS efficiency evaluation is the probability of timely delivery of various messages such as command, service, etc.<ref>{{cite journal |trans-title=Efficiency Evaluation of Enterprise Information Systems with Non-uniform Load |language=ru |url=http://ntv.ifmo.ru/en/article/13881/ocenka_harakteristik_funkcionirovaniya_korporativnyhinformacionnyh_sistem_s_neodnorodnoy_nagruzkoy.htm |author1=Kalinin I.V. |author2=Maharevs E. |author3=Muravyeva-Vitkovskaya L.A. |title=Efficiency evaluation of enterprise information systems with nonuniform load |journal=Scientific and Technical Journal of Information Technologies, Mechanics and Optics |volume=15 |issue=5 |pages=863–868 |year=2015 |doi=10.17586/2226-1494-2015-15-5-863-868|doi-access=free }}</ref>

==Information systems==
{{main|Information systems}}
Enterprise systems create a standard [[data structure]] and are invaluable in eliminating the problem of information fragmentation caused by multiple information systems within an organization. An EIS differentiates itself from [[legacy system]]s in that it is self-transactional, self-helping and adaptable to general and specialist conditions.<ref name="eidvtai" /> Unlike an enterprise information system, legacy systems are limited to department-wide communications.<ref name="eiscmta" />

A typical enterprise information system would be housed in one or more [[data center]]s, would run [[enterprise software]], and could include applications that typically cross organizational borders such as [[content management systems]].
