The data management module enables you to conveniently create, store, manage, and protect various types of data, especially spatial data. Through comprehensive and flexible management of workspaces, data sources, datasets, mosaic datasets, etc., it ensures the secure and efficient utilization of all types of GIS data in SuperMap applications. This chapter includes the following content:

• Data Organizational Structure: Introduces the data organizational structure, including workspaces, data sources, maps, layouts, scenes, etc.
• Manage Workspace: Supports operations such as opening, saving, saving as, and deleting different types of workspaces. Provides user-friendly management tools, including catalog manager and workspace view.
• Data Source Management: A data source is a medium for storing spatial data. Depending on the engine type, data sources are categorized into file databases, database data sources, and web data sources. In addition to basic operations like Create, Open, Delete, data source management also includes operations such as Copy, Compact, Sort, etc.
• Dataset Management: Supports management of datasets in various geographic formats, such as point, line, polygon, text, 3D point, 3D line, 3D polygon, attribute datasets, etc. You can New, Open, Delete, Copy, Rename datasets, and set the Encode Type for datasets.
• Spatial Index: Supports four types: q-tree index, R-tree index, mapsheet index, and dynamic index. You can create a spatial index for a dataset, rebuild an existing spatial index, and perform other management operations.
• Image Pyramids Manager: Supports building pyramids for raster image datasets, deleting existing image pyramids, or viewing image pyramid information.
• Manage Mosaic Dataset: Supports building mosaic datasets to manage massive image data.
• Manage Streaming Data: Supports configuring streaming data services, sending and receiving real-time stream data.
• Manage Data Version: Supports registering data versions in PostGIS and Yukon databases to enable multi-user editing of the same data. It also supports data synchronization, automatic archiving, and adding and viewing data information at specific times.
• Cloud Storage: Supports viewing and loading image data from object storage services in cloud storage. It also supports storing the results of generated tiles in cloud storage.
• Database User Management: Supports creating users and roles for PostGIS and Yukon data sources, and granting edit permissions on data sources/datasets to users or roles.
• Database Transaction: Supports managing database transactions for PostGIS databases to ensure data integrity.
