ExtendSim databases for internal data storage
Overwriting an existing database
When one database is imported into a database with the same name, but- tons allow you to choose how the import should be handled. If the original database had more tables than the imported one, a new button (Overwrite and Delete), removes the extra tables.
The command Database > Export
Database is only active when an
ExtendSim database window is
active. This command exports the
entire ExtendSim database into a
text file. You do this so you can
import the database into another
model, send the database to another
user, or to prepare a database text file for use by the ExtendSim DB Add-In for Excel (dis- cussed on page 760). To export only specific tables from a database, see the Export Selected Tables command, discussed below. To enable this command, bring a database window to the front, as described under Database menu, above.
☞ Exported databases can only be imported to ExtendSim or to the ExtendSim DB Add-In for Excel.
Managing database tables and using tabs
Tabs are useful for organizing tables by cate- gory. The All Tables tab will always contain a list of all of a database’s tables in its table list pane. You can also list some of those tables in other tabs. The database window must be in structure mode to add a tab. To create the tab, either double-click the blank area of the tab bar (that is, to the right of the All Tables tab) or give the command Database > New Data- base Tab. Clone a table to the new tab by selecting the table in the tables pane and giv- ing the command Database > Clone Selected Tables to Tab. In the dialog that appears, select a tab to clone the table to.

Overwriting an existing database
Import and append tables into the current database by giving the command Database > Import Tables when a database’s window is open. This imports a database text file of tables from an ExtendSim or SDI Industry database.
Export selected tables by using the Database > Export Selected Tables command. The tables can be exported as text files from one ExtendSim database to a different ExtendSim database.
To show/hide tables in the tables pane, unselect the table in the list of tables in any tab in the database window.
