Thank you for using ER/Studio Data Architect, previously known as ER/Studio, the award-winning data modeling application for logical and physical database design and construction. ER/Studio Data Architect's (ER/Studio DA) powerful, multi-level design environment addresses the everyday needs of database administrators, developers and data architects who build and maintain large, complex database applications.
ER/Studio Data Architect's progressive interface and processes have been logically organized to effectively address the ease-of-use issues that have plagued data modeling tools for the past decade. The application facilitates your ability to create, understand and manage the mission-critical database designs within an enterprise. It offers strong logical design capabilities, bidirectional synchronization of logical and physical designs, automatic database construction, accurate reverse engineering of databases, and powerful HTML-based documentation and reporting facilities. Before you use ER/Studio, please read the information below.
Important Installation Notes
- To install ER/Studio Data Architect on Windows 11, 10, 8.1, or 7, you must have administrative privileges. Once you have installed ER/Studio DA, you can then log in as a standard or limited user and use the application without having administrative privileges.
- In order to run ER/Studio DA, you must provide valid licensing information.
- When you install ER/Studio DA, certain files and directories that were previously stored under the Program Files folder are now by default installed to system-specified application data directories.
- During installation, the following directories are created:
- For Datatype Mapping Editor files, which is also the default location for user-generated Datatype Mapping files:
- C:\ProgramData\IDERA\ERStudioDA_XXXX\DatatypeMapping
- For Automation Handler files, which is also the default location for sample macros:
- C:\ProgramData\IDERA\ERStudioDA_XXXX\Macros
- For sample model files, for which a shortcut is generated in the ER/Studio DA program group:
- C:\ProgramData\IDERA\ERStudioDA_XXXX\Sample Models
- When the application is run for the first time, the following directories are created by ER/Studio DA:
- Directories used by the Repository client to transfer files to and from the Repository server:
- C:\Users\<user>\AppData\Roaming\IDERA\ERStudio\RepoIn
- C:\Users\<user>\AppData\Roaming\IDERA\ERStudio\RepoOut
- Default directory for Report files:
- C:\Users\<user>\AppData\Roaming\IDERA\ERStudio\Report
- Default directory for SQL scripts:
- C:\Users\<user>\AppData\Roaming\IDERA\ERStudio\SQLCode
- Default directory for Quicklaunch files:
- C:\Users\<user>\AppData\Roaming\IDERA\ERStudio\XML
- Default Save location for new diagrams:
- C:ProgramData\IDERA\ERStudioDA_XXXX\Sample Models
Important Release Advisory
Note regarding installing on Windows
In some situations, background tasks may cause the installation to appear as though it has stopped, even though the progress on the setup window is indicating 100%. In these instances there may be a popup message indicating that a restart is required to finish installation. However, that message may be hidden behind the setup window. Try pressing ALT + TAB to bring the message to the foreground and answer to restart your computer and finish the installation.
Ensure Repository Sync
To ensure compatibility with ER/Studio Repository synchronization, this version of ER/Studio Data Architect requires ER/Studio Repository version 19.1 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 who 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 are not allowed.
