00005 <p>The Feature Data Objects (FDO) API provides access to data in a
00006 data store. A provider is a specific implementation of the FDO API
00007 that provides access to data in a particular data store. The FDO
00008 Provider for ESRI ArcSDE provides FDO with access to an ArcSDE-based data store
00009 (that is, with an underlying, supported Oracle or SQL Server
00010 database).
00011 </p>
00012
00013 <p>You can connect via ArcSDE to an underlying Oracle or SQL Server database.
00014 You can insert, select, update, and delete feature data in existing ArcSDE
00015 schemas. However, you cannot create or modify an ArcSDE schema.
00016 </p>
00017
00018 <p>To work with ArcSDE, you must install ArcSDE 9.1 and a supported data source,
00019 such as Oracle 9<i>i</i>, in the network. The host machine running AutoCAD Map
00020 3D, for example, must also have the required DLLs (three dynamically linked
00021 libraries, sde91.dll, sg91.dll, and pe91.dll) and the PATH environment variable
00022 must reference the local folder containing these DLLs. To accomplish this, you
00023 can install an ArcGIS 9.1 Desktop application or the ArcSDE SDK. For more
00024 information about ArcGIS 9.1 Desktop applications and the ArcSDE SDK, refer to
00025 the ESRI documentation.
00026 </p>
00027
00028 <p>Furthermore, AutoCAD Map 3D uses facilities provided by ArcSDE for long
00029 transaction versioning and persistent locking. (ArcSDE supports one or the
00030 other, but not both, on the same class). ProductName uses the standard
00031 ArcSDE API and ArcSDE-supported storage on both the Oracle and SQL Server
00032 platforms. AutoCAD Map 3D does not use FDO metadata for ArcSDE schemait uses
00033 existing metadata only.
00034 </p>
00035
00036 <p>If ArcSDE encounters curved segments, it converts them to a series of line
00037 segments that approximate the original arc segment (an approximation of the
00038 original geometry).
