API Reference | OSGeo FDO Provider for ArcSDE |
00001 /*! \mainpage Introduction 00002 <div class="mainpage"> 00003 <!-- This is the index.html page that the user first sees. --> 00004 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 schema—it 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). 00039 </p> 00040 00041 <p> 00042 For more information, see <i>The Essential FDO</i> (FET_TheEssentialFDO.pdf) 00043 and the <i>FDO Developer's Guide</i> (FDG_FDODevGuide.pdf). 00044 </p> 00045 00046 <br> 00047 </div> 00048 */ 00049 00050 00051 00052
