The Spatial Data Engine is an implementation method of the spatial database management system. That is, a layer of spatial database engine is added to the conventional database management system, in order to obtain space data storage and management capabilities beyond the features of the conventional database management system. The Spatial Data Engine provides an open interface between users and data in different types of spatial databases.ProgramAnd the middleware technology between the database management system. GIS customers of different manufacturers can submit their own data to large relational DBMS through the Spatial Data Engine for unified management by DBMS. Similarly, you can also use the spatial data engine to obtain data of other types of GIS from the relational DBMS and convert it into a method that can be used by the customer.
Supermap sdx + is a space engine technology of Supermap. It provides a general access mechanism to access data stored in different data engines. Supermap sdx + is an important component of the Supermap GIS software data model. It adopts advanced spatial data storage technology, Spatial Indexing Technology, and data query technology, the integrated spatial data engine technology includes space-attribute data integration, vector-raster data integration, and space information-service information integration, it is an ideal choice for large GIS projects, small and medium-sized projects, or desktop applications.
Data is the soul of GIS. data storage and access performance affect the performance of the whole GIS application. Therefore, the functional integrity and performance of spatial data engines directly affect the functional integrity and operational efficiency of GIS applications. Supermap sdx + spatial data engine runs stably, features are mature, and performance is superior. It can store the spatial geometric object data and attribute data of GIS in multiple data engines, including a variety of large relational databases and file-type data sources, which can efficiently index, maintain, append, update, and delete data, it can query attributes and space based on Attribute conditions or spatial location conditions, and provides advanced functions such as long transactions, version, time series, and Topology maintenance.
for the above description, Supermap SDK + is essentially a storage and query mechanism between the data required by the user and the Data Engine that cannot be accessed. By defining a complete set of schemas, you can define interoperability and access methods between different data formats. This allows you to store, access, and manage data between users and data engines.
