What's New in Version 19.1

Adds support for multiple Oracle 12c and later features

ER/Studio Data Architect 19.1 includes support for the following features in Oracle 12c and later:

·        External tables. External tables allow Oracle to query data stored outside of the database in flat files. Use the Table Editor option to designate an external table and gain access to the External Table Properties dialog for further definition of the table. For more information about this feature, see Defining Table Storage: Oracle 12c and Later Storage Options.

·        Saving varchar size units as BYTE or CHAR for physical models. For more information about this feature, see Defining Model Options for the Selected Model and Generating a Physical Data Model.

·        Subpartitioning by RANGE. Range partitioning distributes data based on a given range, as in time intervals and allows you to easily add new data while purging older data. For more information about this feature, see Subpartition Editor.

·        Identity columns. Identity columns allow you to auto-increment values each time you add a row. You can set only those columns having a Data Type of Number as identity columns, and you may have only one Identity column per table. For more information about this feature, see Creating and Editing Columns: Datatype tab.

Adds support for multiple Oracle 11g and later features

ER/Studio Data Architect 19.1 includes support for the following features in Oracle 11g and later:

·        Interval partitioning. Interval partitioning automatically partitions a database at specified intervals when new data added to the table exceeds all of the specified range partitions to avoid insert failures. Use the Partition tab of the Table Editor to set what interval is in use. For more information on this feature, see Partitioning a Table: Table Partition Options for Oracle.

·        Reference partitioning. Reference partitioning allows you to partition two tables that are related based on an existing parent-child relationship. You can manage partition keys and types on the Partition tab of the Table Editor. For more information on this feature, see Partitioning a Table: Table Partition Options for Oracle.

What's New in Version 19.0.1

Supports additional features for SQL Server Temporal Tables

ER/Studio Data Architect 19.0.1 includes additional support for SQL Server Temporal Tables, allowing users to designate in-memory tables and have Data Architect check whether the columns are suitable as not all datatypes are supported for in-memory. For more information about this feature, see Microsoft SQL Server Table Storage Options.

Allows users to switch between open files

This release includes the addition of the Switch Windows button in the Diagram ribbon. This button allows the user to switch and view each of the different open files.

Adds the Universal Mappings button to the Repository ribbon

The new Universal Mappings button on the Repository ribbon allows users to create links between objects across models, which are visible in the Where Used tab of Objects and in Team Server Core.

Adds the Diagram Properties button to the Model ribbon

The new Diagram Properties button on the Model ribbon allows users to easily set properties for the diagram file.

Adds quotation marks to the Field Names when generating the database JSON

New options allow users to select how the plain JSON output is generated from MongoDB-specific content. For more information about this feature, see MongoDB JSON Generation.

What's New in Version 19.0

Supports Azure Active Directory Password authentication method

Release Notes

Important Release Advisory


To ensure compatibility with ER/Studio Repository synchronization, this version of ER/Studio Data Architect requires ER/Studio Repository (Team Server) version 19.1 or later for all Repository operations.

ER/Studio Portal is no longer supported by ER/Studio Data Architect. Most functionality formerly provided by ER/Studio Portal is now provided by ER/Studio Team Server. Users that formerly used the Repository tab to browse the portal can use a Web browser instead.

License Enforcement

When working with the Repository, all users must use the same license type. ER/Studio now enforces this by marking the Repository as an Enterprise Team Edition Repository when a user with an Enterprise Team Edition license logs in. Subsequent log in attempts by users with a non-Team Edition license will not be allowed
