Function Description
supports creating three types of datasources: File Database, Database Datasource and EMS Datasource. The default coordinate system for new datasources is GCS_China_2000. You can modify the epsgCode in <DefaultPrjCoordSys epsgCode="4490"/> at Product Package/configuration folder/Desktop.Parameter.xml to customize your default coordinate system. For characteristics and application scenarios of different datasource types, please refer to Datasource Overview.
Feature Entry
- File Tab -> New Button -> Select Datasource Type
- Start Tab -> Datasource Group -> File Dropdown -> Select New File Datasource, New Memory Datasource or Create Datasource from Template
- Start Tab -> Datasource Group -> Database Dropdown -> New Database Datasource
- Workspace Manager Panel -> Datasource Node Context Menu -> Select New Datasource Type

New datasource supports password setting. When opening password-protected datasources in workspace, password input is required. If a password-protected datasource has been opened and saved in workspace, no password is needed when reopening the workspace.
Steps
New File Datasource
Access the feature entry mentioned above via New -> Create File Database. In the dialog box, set the save path, filename and file type to create corresponding file database. Available file types include *.udb or *.udbx.
New Folder Data Source
Through Workspace Manager Panel -> Datasource Node Context Menu -> New Folder Data Source. In the dialog box, set the save path and filename. Currently FileGDB is the only supported file type for folder-type datasources.
New Database Datasource
Currently supports creating various database datasources including SQLPlus, Oracle Plus, Oracle Spatial, PostgreSQL, PostGIS, Yukon, MySQL, POLARDBGanos, GaussDB 200, DMPlus, KingBase, HighGoDB, SHENTONG, Vastbase, Yashan, etc.
Creating some datasource types requires local client configuration. Parameter descriptions, configurations and precautions for different database types are consistent with Open Database Datasource.

- When creating PostGIS database datasource: You can either specify an existing PostgreSQL database name to create datasource, or specify a new database name - the system will first create corresponding PostgreSQL database then create datasource. Only one PostGIS database datasource can be created per PostgreSQL database.
- One Oracle database user can only correspond to one datasource. If the user already has existing datasource, new datasource cannot be created through this user. Please manually create new user in Oracle first.
Create Datasource from Template
Create a datasource identical to template datasource (equivalent to copying template datasource). The new datasource maintains same dataset quantity, names and types as template, but only retains table structures with zero records (empty datasets without objects).
The application currently provides two templates: National Geographic Census and Basic Geographic Information Topographic Element Classification. Users can also specify other datasources in workspace as templates.
