Instructions for Use

Datasource (Datasource) is used to store spatial data, any operation on spatial data needs to open or create a data source. Users can create a suitable data source according to the purpose of the data, and save different spatial data in the data source, which is convenient for unified management and operation of the data. Datasources are mainly divided into the following two categories:

• File data source Store spatial data and attribute data directly into files, and support new data sources of type udb and udbx. File-type data sources display faster maps in the case of small data volumes, and data migration is more convenient.

• Database data source Store the data source in the database. Currently, it supports the creation of Dameng Database, Hangao Database, Huawei Cloud Database PostgreSQL, Kongtian Database, Renda Jincang, Shenzhou General Database, Yugong Spatial Database, Elasticsearch, OraclePlus, OracleSpatial, SQLPlus, SQLSpatial , PostgreSQL, MySQL, PostGIS and MongoDB and more than ten kinds of database-type data sources. The creation of some data source types requires local client configuration, and different database types have different parameter settings. For parameter descriptions, parameter settings, and precautions, please refer to "Opening a Database Data Source". Database-type data sources are often used for data storage with a large amount of data, which is convenient for data management and access, and supports concurrent operations for easy modification and data synchronization.
