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, datasources, datasets, mosaic datasets, and more, it ensures the secure and efficient use of all types of GIS data in SuperMap applications. This chapter includes the following content:

• Data Organization Structure: Introduces the data organization structure of , including workspaces, datasources, maps, layouts, scenes, and more.
• Manage Workspace: Supports operations for opening, saving, saving as, and deleting different types of workspaces. Provides easy-to-use management tools, including the Catalog Manager and Workspace View.
• Datasource Management: A datasource is a medium for storing spatial data. Based on different engine types, datasources are classified into file databases, database datasources, and web datasources. Datasource management includes basic operations such as Create, Open, and Delete, as well as operations like Copy, Compact, and Sort.
• Dataset Management: Supports managing datasets in various geographic formats, such as points, lines, regions, texts, 3D points, 3D lines, 3D regions, and attribute datasets. You can New, Open, Delete, Copy, and Rename datasets, as well as set the Encode Type of datasets.
• Spatial Index: Supports four types of indexes: 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 to send and receive real-time stream data.
• Manage Data Version: Supports registering data versions in PostGIS and Yukon databases to enable multiple users to edit the same data simultaneously. It also supports data synchronization, automatic archiving, and adding and viewing data information at specific points in time.
• Cloud Storage: Supports viewing and loading image data from object storage services in cloud storage. It also supports storing generated tile results in cloud storage.
• SuperMap iServer Server Management: Supports connecting to SuperMap iServer servers, browsing service directories based on user permissions, and loading available services as workspace datasources.
• Database User Management: Supports creating users and roles for PostGIS and Yukon datasources, and granting users or roles editing permissions on datasources/datasets.
• Database Transaction: Supports database transaction management for PostGIS databases to ensure data integrity.
