This table lists major enhancements made to Teradata Meta Data Services Release 15.00 features. The enhancements include support for Teradata Database 15.0 features and Teradata Meta Data Services-specific improvements.
| Supported Feature | Description |
|---|---|
| JSON Data Type | JSON is a UDT-based Teradata data type. It can be used wherever other data types are allowed – table and view columns, macro parameters, etc. MDS 15.00 does not extract values from JSON columns, or track JSON object references in the MDS repository. |
| UDT Cast, Transform, Ordering Operations | A UDT cast operation converts a UDT value to another data type. A UDT transform operation is used to convert the UDT data between the database format and the application program’s internal format. A UDT ordering operation is used to sort the UDT values. |
| Teradata Table Functions | Table functions are UDFs that return a table with columns and rows as the output result. Rather than returning something simple like an integer or a character string, the function returns a fully formed table that can be iterated through. |
| Partitioned Primary Index | Partitioning means rows with the same range of values for one or more columns are stored in the same block(s). It can be defined for a table or a join index, on a primary index (PPI) or column group. MDS 15.00 supports PPI and not column partitioning. |
| MERGE INTO Transformation Information | BTEQ Reader will search for transformation-type SQL found in a given BTEQ script file, and produce an XML file, in CWM XML/XMI format, which contains the tables and columns from both the "source" and "target" database schema found in the BTEQ script. |
| Repository Explorer Impact Analysis | Identify invalid references, view to base table mappings, column to view mappings, objects that reference a table, intermediate views, etc. |
| Multi-keyword Business Search | The Business Search in Repository Explorer provides a new option for multi-keyword search. The user can now search for multiple keywords at once. |
| Object Lookup by ID | Repository Explorer provides look up of an object by specifying the object ID. |
