ArcCatalog is a geobase administration application within ESRI's ArcGIS suite whose primary role is to maintain geospatial data and the corresponding metadata. ArcCatalog provides an integrated and unified view of all the data files, databases, and ArcGIS documents, integrating information that exists in many forms, including relational databases, files, ArcGIS documents, and remote GIS web services. In ArcGIS 10, ArcCatalog is folded into ArcMap - the mapping and analysis application. Users have several choices of how metadata is displayed and metadata editing is easily performed as the Federal Geographic Data Committee (FGDC) metadata requirements are enforced in the application. Metadata is stored in an XML file that 'stays' with the geospatial dataset. ArcCatalog also allows users to connect to other geospatial data servers, create address locators, and create connections to other databases (ODBC) and spatial databases (SDE).
