1. Fully support Spatial Info storage platform
SuperMap SDX + fully supports the current mainstream commercial relational database platforms, in addition to supporting the top four Oracle, MS SQL Server, PostgreSQL, and MySQL in the global market. It also supports the domestic DM3 (Damon Database), Kingbase (Kingbase Database), Ali PolarDB, etc. With independent intellectual property rights; it can also directly access the Web services provided by WFS, WMS, WCS, etc; SuperMap's UDB and UDBX are also supported.
SuperMap SDX + provides full support for these Spatial Info storage platforms, providing fully transparent access for clients. SuperMap SDX + encapsulates the access interfaces of these database platforms in a consistent way, so users do not need to care about what kind of server hardware platform and operating system platform these data are running on, and do not need to know the type of background database, the type of server and the type of operating system, they can store and manage the data according to a unified interface. It greatly simplifies the configuration, development and application of Spatial Data database.
2. Fully support various spatial Object Types
SuperMap SDX + provides comprehensive support for spatial Object Type, which not only supports traditional spatial objects of point, line and surface types, Also supports Text (TEXT), Compound (CAD), Network, Route, TIN, DEM, Video, Complex data models such as Grid Data (GRID) and Image Data (Image).
3. Adopt advanced Spatial Index technology
Index technology is a key technology of Spatial Data database engine, which directly affects the efficiency of Spatial Data access and query. SuperMap SDX + provides R-tree Index, Q-tree Index, Dynamic Index (multi-level grid index) and Mapsheet Index (three-level index), giving full play to the advantages of each index. It improves the efficiency of data access and query, and meets the needs of Get Data when massive images and vector Spatial Data are stored together.
4. File caching technology
File caching is an intelligent distributed storage solution provided by SuperMap SDX + to balance network and server loads and improve the overall performance of applications. After the file cache is enabled, when the program accesses the data stored in the Spatial Database or the network, it will first check whether there is a Newest Version of the corresponding data in the local cache database. If there is no corresponding Cache Data or the Cache Data is not the Newest Version, The data is read from the server side and the local Cache Data is updated, so that the local Cache Data can be directly read during the next access; If the local cache already has the Newest Version of the corresponding data, it is not necessary to request the data from the server through the network, but to read the local Cache Data directly to complete the display or analysis function. With this Solution, the database server load and network load can be significantly reduced, thereby significantly improving the overall performance of the Application.
5. Support data lossy/lossless compression
SuperMap SDX + supports lossless compression and lossy compression for both vector and Raster Data, and can intelligently determine the compression Parameters according to the characteristics of Spatial Data, without the need for users to make tedious settings. The operation steps are simplified on the basis of ensuring high compression ratio and time performance.
