Database Model

The database model will be generated when we read data from the database. The database model is similar to the lineage model and it contains extra db info.

The object under the server block is same as Dbobjs in lineage model. Check Dbobjs to understand more about this field. Apart from the server block, check following table for more details:

Field name	Description
createTime	database model export time, usually it can be the time you execute the exportation
createdBy	name of the export tool sqlflow-ingester v1.1.8 for example
physicalInstance	your server address, 106.54.xx.xx for example
errorMessages	errors during the exporting
