Fields like the region, country and city names are brought from the related tables, walking through the relationships. The Regions– Countries– Locations chain allows you to group or filter by the geographic location of his/her department.ĮmpDetailsView is a database view, that uses denormalized data for the employees. The Jobs– JobHistory branch allows you to drill-down into the log of an employee based on his/her work history in time, and the occupied positions. The central Departments– Employees relationship reminds us of the old scott/tiger schema ( scott schema/user name, with tiger password), which inspired our own Employees sample. HR implements the small database of a Human Resources department. An asterisk means data is optional in that field. Unlike the previous image, the next Model Xtractor diagram shows all HR tables with full column descriptions, including their specific physical data type. To use it, you’ll have to enable the HR user/schema first.
HR schema is the main example database in the Oracle distribution.
Be aware that large remote databases, with many tables and large numbers of records, may take a while for this update. When data changes, the row count and the estimate size are not automatically updated, so you’ll have to do it manually again, if needed.

To count or re-count the number of rows, and estimate the total stored size, click on the Tables node, select all table items from the Objects list, and call Update Row Count. The inventory section holds also thousands of films, with their list of actors. You can group and filter customers per country or city. Most data is concentrated in the payment and rental tables. A fourth area lists the database views, in collapsed form. We separated the tables into three different areas: Customer Data, Inventory and Billing. All our diagrams will use Crow’s Foot‘s notation here (default is a Model Xtractor simplified notation, with ERwin’s IDEF1X as third option). While MySQL Workbench can create some nice-looking database diagrams, here is one with Model Xtractor. Another port of sakila in PostgreSQL is Pagila. The dvdrentalexample database from PostgreSQL is actually sakila.

This implements the back-end database of a fictional medium-sized store selling movie DVDs. Main sample database in MySQL or MariaDB is sakila.
