   Figure 5 Functions
   
   • Model Design Process: The selected processes are automatically executed progressively when a table created in an ER or dimension model is published and suspended. You are advised to select all the options.
     • Create tables: After a table publishing application is approved in DataArts Architecture, the system creates a physical table in the corresponding data source. When a table is deleted, the system deletes the corresponding physical table.
     • Synchronize technical assets: After a table in ER Modeling or Dimensional Modeling is published, the table is synchronized to the DataArts Catalog module as a technical asset, and the tag is synchronized to the corresponding technical asset.
       

       To enable Synchronize Technical Assets, you must create a data asset collection task for the database to which the table belongs in DataArts Catalog. Otherwise, the technical asset synchronization will fail.

     • Synchronize logical assets: The system synchronizes logical models to DataArts Catalog as logical assets. After that, the system tags the logical assets accordingly.
     • Associate assets: Associate logical assets with technical assets. After the logical assets and technical assets are synchronized, you can view the associated technical or logical asset when viewing the details of a logical or technical asset on the DataArts Catalog page. This function requires that the table information contains the data source information.
     • Create data quality jobs: After a table in ER Modeling or Dimensional Modeling is published and approved, the system automatically creates a quality job in the DataArts Quality module of DataArts Studio for a table that is associated with a data standard (including the data length or allowed value) or associated with a quality rule.
     • Create data development jobs: After a summary table is published, the system generates an E2E data development job.
     • Publish DataArts DataService APIs: After a summary table is published, a DataArts DataService API is automatically generated. This function takes effect only DataArts DataService supports data connections of the summary table.
     • Insert data: After a lookup table is published, values in the table are automatically written to the dimensional table.
   • Model Suspension Process: Select whether to delete technical assets, logical assets, data quality jobs, and data development jobs when suspending the job.
   • Data Table Update Mode: If a table in DataArts Architecture is modified after being published, you can choose whether to update the table in the database and how to update the table. By default, the table is not updated. However, you can set the update operation in the configuration center as required. To be more specific, configure the corresponding update statements in the DDL templates.
     • No update: The system does not update tables in a database.
     • DDL-based update: The system updates tables in the database based on the DDL update template configured in DDL Templates. The underlying data warehouse engine determines whether the update is successful. Different types of data warehouses support different table update modes. If the data warehouse does not support table update operations on the DataArts Architecture page, the tables in the database may be inconsistent with those in DataArts Architecture. For example, table fields cannot be deleted when DLI tables are updated. If table fields are deleted from the tables in DataArts Architecture, the corresponding table fields cannot be deleted from the database.

       If the offline database supports the syntax for updating the table architecture, you can configure the syntax in the DDL template. Then, the update operation can be performed. Otherwise, update the table by rebuilding it.

     • Drop and create: The system deletes an existing table in a database and then creates a table. This option ensures that the tables in the database are the same as those in DataArts Architecture. However, since the table is deleted first, you are advised to select this option only in the development and design phase or test phase. After the product is brought online, you are not advised to select this option.
   • Case Insensitive During Technical Assets Synch: When a table, whose type is the same as the data connection, is published, the data connection name is case insensitive during technology asset synchronization. If the name is the same as an existing one, the connection exists.
   • Physical Table Synchronize Logical Assets: If Synchronize logical assets is selected and no logical asset is available, you can disable this option to prevent physical tables from overwriting logical tables which have the same names as them. In this case, physical tables will only be associated with, but not synchronized to logical assets. If no logical asset is found, the association fails and an error is reported.
   • Use New UI to Deliver Business Table Mappings: This function is enabled by default. The mapping function of the new version supports operations such as join. You are advised to use the mapping function of the new version.
   • Auto Aggregate Summary Tables: When publishing a derivative or compound metric, the system automatically generates a summary table. A statistical dimension corresponds to a summary table. You can click the Automatic Aggregation tab on the summary table page to view the automatically generated summary tables.
   • Data Standard Allows Duplicate Names: This function is disabled by default. If it is enabled, duplicate data standard names are allowed.
   • Auto Directory Creation During Data Standard Import: This function is enabled by default.
   • Enable Public Layer: If this option is enabled, the current workspace can be converted into a public workspace. The lookup tables and data standards of the public workspace are shared with all common workspaces. In a common workspace, you can query or reference the lookup tables and data standards of the public workspace, but cannot add, modify, or delete them.
     

     • After the current workspace is converted to a public workspace, it cannot be rolled back to a common workspace, and no other common workspaces can be converted to a public workspace. Exercise caution when selecting your public workspace.
     • You cannot query, reference, or operate the data of a common workspace from a public workspace.
   • Time-limited Generation Using Dynamic Expressions: If you enable this function, dynamic time expressions will be used; otherwise, the default static time expressions will be used. The dynamic expression automatically updates the generated time, while the static expression does not. For example, if the current month is September and a static expression is used, data generated for the last 30 days is the data in August. Even when the current month changes to October, data generated for the last 30 days is still the data in August. However, if a dynamic expression is used, data generated for the last 30 days will automatically change to the data in September if the current month has changed to October. The following figure shows an example time function using a dynamic expression.
     Figure 6 Dynamic expression
     
     

     If you enable this function for the first time, you need to reset the derivative metrics in the DDL template. If you have made any change to the DDL template, back up the template before resetting it. Resetting the template will overwrite any change that has been made. After the template is reset, you must make the changes again.

   • Parallel Queried Tables on Information Architecture: The default value is 1. Currently, you cannot change the value.
   • Concurrently Insertable Lines of Data: The value determines the number of lines of the dimensional table into which data of the lookup table is inserted. If the lookup table contains a large amount of data, the data may fail to be inserted into the dimensional table. In this case, you can reduce the value of this parameter.
   • Lookup Table-based Quality Rule: Select a value from the drop-down list box. If the data volume of the lookup table is small, select Enumerated value verification; otherwise, select Field value consistency verification.
     

     You can select Field value consistency verification only if the database contains a lookup table. The following lookup tables are contained in the database:

     • Lookup tables obtained by database reversion
     • Lookup tables published during dimension creation
   • Naming Rule for Dimension Fields Referenced by the Summary Table: Set the naming rule for a summary table during creation, editing, import, and generation. Select Dimension table name_Dimension attribute name or Dimension attribute name.
   • Exported File Type: Two options are available: xlsx and et. Logical models, physical models, dimensions (dimension tables), fact tables, summary tables, and other data can be exported in both formats.
   • Generate DataArts DataService APIs: Two options are available: Table API and Metric APIs.

Model Settings

You can perform the following operations during subject design and model design on the Model Settings page.

• Add the subject alias, table model alias, and field alias.
• Set the default table code prefix for dimension tables, fact tables, and summary tables.
• Add custom fields to a table.
• Add custom fields to an attribute.

Figure 7 Model Settings tab page
