Through the iterativeDataset tool, the datasets of the data source can be processed in batches, thereby saving the time required for repeated operations and improving the processing efficiency.
Dataset (Dataset) is the basic data set type used by iObjects Java, and it is the smallest unit of GIS data organization. The tool supports docking with multiple data sources,currently supported：
| Parameter Name | Default Value | Parameter Definition | Parameter Type |
|---|---|---|---|
| Open Data Source | Open the connection information for the data source，Use '--key=value' to set，Multiple values are separated by ' ' spaces. Ways to open a data source include： 1.Open file data source（udb/udbx)： C:/test.udbx OR： --server=C:/test.udbx --dbtype=udbx --alias=sichaun 2.Open the PostGIS database： --providerType=jdbc --host=172.16.16.9 --database=test --user=postgres --passwd=supermap --dbtype=PGGIS 3.Open the PostgreSQL database： --providerType=jdbc --host=192.168.113.7 --database=test --user=postgres --passwd=supermap --dbtype=POSTGRESQL 4.Open the SQLPlus database: --providerType=jdbc --host=192.168.17.21 --database=test --user=sa --passwd=map --dbtype=SQLPLUS 5.Open the OracleSpatial database： --providerType=jdbc --host=192.168.17.21:1521/orcl --user=testosp --passwd=testosp --dbtype=ORACLESPATIAL 6.Open the MySQL database： --providerType=jdbc --host=192.168.17.21:3306 --database=test --user=user --passwd=map --dbtype=MYSQL Open the MongoDB database： --providerType=jdbc --host=192.168.17.31:27017 --database=lijt_mg --dbtype=MONGODB |
