+## DolphinScheduler Datasource SPI main design
+
+#### How do I use data sources?
+
+The data source center supports PostgreSQL, hive / impala, spark, Clickhouse
and sqlserver data sources by default.
+
+If MySQL and Oracle data sources are used, the corresponding driver package
needs to be placed in the plug-in installation directory
+
+#### How to use development environment?
+
+Note: **${VERSION}** needs to be manually modified according to the current
version.
+
+First you need to execute the `mvn -U install -Dmaven.test.skip=true` to
install the plugin for generating the plugin JAR of the registry. The directory
is:
dolphinscheduler-dist/target/dolphinscheduler-dist-${VERSION}/lib/plugin/task
(The version number will follow the change of the main version number)
+
+Executing this command will generate all plugins provided by default for all
modules.
+
+Next, configure the plugin directory in
(dolphinscheduler-server/src/main/resources/worker.properties)
+
+```
+datasource.plugin.dir
=./dolphinscheduler-dist/target/dolphinscheduler-dist-${VERSION}/lib/plugin/datasource
+```
+
+The following configurations can be used for local development debugging, for
example:
+
+```
+maven.local.repository=/Users/localRepository
+datasource.plugin.binding=./dolphinscheduler-datasource-plugin/dolphinscheduler-datasource-sqlserver/pom.xml
+```
+
