ArcSDE (Spatial Database Engine) is a server-software sub-system (produced and marketed by Esri) that aims to enable the usage of Relational Database Management Systems for spatial data. The spatial data may then be used as part of a geodatabase. == History == Geographic Technologies Incorporated (GTI) in Australia originally designed the database software, named Spatial DataBase Engine (SDBE). Development shifted to Salamanca Software Pvt Ltd., which developed the first production version. SDBE originally used the InterBase DBMS. The president of Esri, Jack Dangermond, announced SDE at the GIS'95 conference in Vancouver, British Columbia, and Esri purchased Salamanca Software in 1996. Esri rebranded the software as "ArcSDE" to follow the naming convention of other products. ArcSDE grew to meet the need of users of geographic data for robust multi-user editing, storage and access of extremely large geospatial databases. ArcSDE supports the Esri geodatabase implementation. The product began as stand-alone software: Esri integrated it into ArcGIS version 9.2.〔 〕〔 (【引用サイトリンク】 title = Geodatabase (web page), ArcSDE Technology (subtitle) ) 〕 In 2013 ESRI announced plans to deprecate the ArcSDE command line tools and the ArcSDE application server following the forthcoming release of ArcGIS 10.2.〔 〕 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「ArcSDE」の詳細全文を読む スポンサード リンク
