The Integration of ArcInfo and ArcSDE: A True Enterprise GIS Solution
Over the past several years, Esri has been developing and offering SDE software technology for enabling spatial data management within standard DBMS technology.
This technology has been popular within both the GIS and IT/IS communities because it provides very fast access to very large spatial databases for a large number of users, at the same time maintaining the spatial data using standard DBMS technology. Initially, Esri offered SDE as an independent spatial database server primarily focused on storage and retrieval of spatial features inside a DBMS. Most users who initially acquired SDE deployed it as a tool to serve spatial data to mission critical applications. This enabled widespread multiuser access in an open environment that fully integrated standard DBMS technology.
With the release of ArcInfo 8, Esri has reengineered and integrated the SDE technology to be an integral part of ArcInfo. What this means is that ArcInfo users will have an open and integrated gateway solution between their GIS applications and any DBMS.
ArcInfo 8 is fully integrated with DBMS technology; this means better data management for GIS users and offers
ArcInfo 8 uses the DBMS to directly manage spatial data using any of the three OGC standards (i.e., normalized tables, binary objects, as well as spatial types). Esri has worked closely with each DBMS vendor to ensure that ArcInfo 8 takes advantage of the best DBMS and object-relational technology solutions provided by each DBMS company. This includes advanced support for the Oracle8i Spatial extension provided by Oracle. Esri also supports solutions for Microsoft's SQL Server, Informix, and IBM's DB2.
ArcInfo 8 and DBMS Integration
Esri is committed to directly and openly support the best solutions provided by each DBMS vendor for spatial data management. We will work closely with these companies to ensure that our GIS solutions take full advantage of new DBMS advances as they are added.
Version 8 integrates ArcInfo with any DBMS using the ArcSDE multi-user/multi-DBMS gateway.
ArcSDE 8 openly supports an efficient gateway between all Esri software products (ArcInfo, ArcView GIS, MapObjects, ArcExplorer, and ArcIMS) and spatial data managed in any supported DBMS.
ArcInfo 8 introduces several key integration technologies in ArcInfo and ArcSDE:
Existing SDE Users
Existing SDE users will automatically be given a copy of ArcInfo 8 as part of their ArcSDE 8 upgrade package. This will include the full functionality of SDE and a full copy of ArcInfo for managing geodatabases.
Why Did Esri Integrate ArcInfo and SDE?
For ArcInfo users, this allows GIS data sets to be better managed using standard DBMS technology. The results will provide better multiuser GIS environments. For SDE users there are also substantial benefits. The last six years of experience have shown us that SDE users (people spatially enabling their DBMS) typically need GIS functionality to create, load, and manage their spatial data. They also need mapping and spatial applications to use this data. It is not enough to simply provide a technology to load, index, and serve spatial data. ArcInfo will also provide a valuable GIS toolbox for Oracle Spatial users.
By integrating GIS with DBMS, Esri is providing a complete solution including
We believe that a DBMS is very important for managing the data of a GIS, and a GIS is needed to create and manage the spatial data maintained in any spatially enabled DBMS. ArcInfo 8 is the world's leading GIS technology for creating, converting, manipulating, and using geospatial data. This, integrated with standard DBMS software, will bring the GIS and IT worlds together.
