AnyLogic database

Each AnyLogic model now has a built-in fully integrated database to read input data and write simulation output. Export the database with the model, it is as portable and cross-platform as the model itself. 

With the new database, you can:

Database can contain tables and views. Both tables and views can be grouped into groups of tables.

You can easily import the database into your AnyLogic project from external database or spreadsheet. Alternatively, you can create empty database tables and enter data manually. 

Properties

General

Size – The label displays the size of the database on disk.

Create or import a table... – Click this link to create a new database table, or import data into the DB from the external database.

Back up database... * – Click this link to create a backup copy of the database. AnyLogic saves the backup copy in TAR.GZ file format. Having backed up the database, you will be able to revert all changes in the database you are working with, by restoring the backed up database (see the property below). 

Restore database... * –  Click this link to restore the database from the backup file. Restoring the database you replace your current database with the reserve copy you have previously created using the Backup database command (see above). The restored database gets reverted to the state it was when you backed it up.

Delete database * – Click this link to completely delete the database.

Use COMPACT for database shutdown * – If selected, on the database shutdown the DB data will be saved onto the disk in optimized way, saving the disk space. However, if the database is huge, shutdowns in COMPACT mode will take the significant time. If the option is not selected, data is saved as is, which produces quick DB shutdowns, but does not care about the DB size on the disk. 

* - The option is available only if the database is not empty.

Import

This properties section is visible if this database contains tables that were imported from an external database. You can set up the data synchronization and update data in the imported tables after making some modifications in the external database.

Autoupdate imported tables on model startup – If selected, data in all imported tables will be automatically updated from the external database on each startup of this model.

Update tables data – Click this link to update data in all imported tables from the external database.

Input data sources – Contains a list of all external files that source data for the imported AnyLogic database tables. If the source file is located outside of the model folder, an absolute path is displayed. If the file is located in the model folder, only the name of the file is displayed.
