The dimension table feature allows you to create MaxCompute tables, import local data to MaxCompute tables, and edit MaxCompute tables in a visualized manner.
- To create a MaxCompute table in DataAnalysis, you must be an administrator, an owner, or a developer of a DataWorks workspace. For more information, see Add workspace members.
- For a MaxCompute table that is created by using the dimension table feature, all fields in the MaxCompute table are of the STRING type. If you need to use fields of other data types, execute Data Definition Language (DDL) statements to create a MaxCompute table on the DataStudio page. For more information, see the "Create a table" section in the Table-level operations topic.
