    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 ODBC provides FDO with access to an ODBC-based data store.
    00009 </p>
    00010 <p>The FDO Provider for ODBC can access simple x, y, z
    00011 feature objects that can run in a multi-platform
    00012 environment, including Windows, Linux, and UNIX.
    00013 </p>
    00014
    00015 <p>The FDO Provider for ODBC has the following characteristics:
    00016 </p>
    00017 <ul>
    00018   <li> The FDO Provider for ODBC supports the definition of one or more
    00019     feature classes in terms of any relational database table that
    00020     contains an X, Y, and optionally, Z columns.</li>
    00021   <li> Metadata--that maps the table name, and X, Y, and optionally, Z
    00022     columns to a feature class--is maintained outside the
    00023     database in a configuration file. This information, in
    00024     conjunction with the table structure in the database,
    00025     provides the definition of the feature class.</li>
    00026   <li> The x, y, and z locations of objects are stored in
    00027     separate properties in the primary object definition of a
    00028     feature, but are accessible through a single class
    00029     property ‘Geometry’.</li>
    00030 <li> Read-only access is provided to pre-existing data defined and
    00031     populated through 3rd party applications (that is, FDO
    00032     Provider for ODBC will not be responsible for defining the
    00033     physical schema of the data store nor for populating the object
    00034     data).</li>
    00035 <li> The schema configuration of the data store is
    00036     provided to the FDO Provider for ODBC through an optional XML
    00037     file containing the Geographic Markup Language (GML)
    00038     definition of the schema that maps ‘tables’ and ‘columns’ in
    00039     the data store to feature classes and property mappings in
    00040     the FDO data model.</li>
    00041 </ul>
    00042 \note
    00043 Microsoft Excel (must have at least one named range; do not use DATABASE
    00044 or other reserved words as a range name)
    00045
    00046 <p>For more information about setting up an ODBC data store in AutoCAD Map 3D
    00047 2008 and configuring Excel for database ranges, see the 'Managing Data' topic
    00048 in the <i>AutoCAD Map 3D User's Guide</i> (acmap.chm).
    00049 </p>
    00050
    00051 <p>For ODBC, only a point geometry (X, Y, and optionally, Z columns define a
    00052 point) is supported. The default column names are X, Y, and Z, but when you pick
    00053 the columns to represent these, you override the defaults. In AutoCAD Map 3D
    00054 2008, this information is stored in the map file itself, so if you go through
    00055 the same process in another map, you will need to override the settings again
    00056 in the same way.
    00057 </p>
    00058
    00059 <p>There is no spatial indexing. Object locations are stored in separate
    00060 properties in the object definition.
    00061 <p>
    00062
    00063 <p>The existing schema is used, and you cannot add, change, or delete it, nor
    00064 can you add FDO metadata to the data store.
    00065 </p>
    00066
    00067 <p>When you set up a Data Source Name for your ODBC data store (by adding a DSN
    00068 in Windows), you will need to specify certain configuration options, depending
    00069 on the type of ODBC data store you use. The connection information (Login ID
    00070 and password) you enter here is used only for defining the DSN, and not at
    00071 connection time with the ODBC provider.
    00072 </p>

    00075 For MySQL, make sure you have installed the MySQL driver from MyODBC 3.51.
