At this point, we have two possibilities: we can start adding tables to our physical schema using the add table icon, or we can start an EER Diagram and add all the tables there. Creating our Tablesīack to our initial example we have to rename the default schema by double clicking the name. The diagram will contain only two tables, but those two tables will also be included in the schema, together with the previous five. For example, we can have a schema with five tables defined, and then create a new diagram to define two more tables using the visual editor. We can use an EER diagram to define the whole database, or just small parts. EER models can be complex, but MySQL Workbench uses only a subset of all possible graphical elements, because the purpose of this diagram (in this tool) is to have every element mapped to the physical schema. EER diagrams are just a way to model the data and the relationships between data using standard symbols. EER stands for Extended (or Enhanced) Entity-Relationship>. They will be listed as databases within the MySQL server host when using SHOW DATABASES. EER diagrams are just a way to model the data and the relationships between data using standard symbols' 'EER stands for Extended (or Enhanced) Entity-Relationship. If we generate the SQL script, we will have two separate CREATE DATABASE statements - actually we will have CREATE SCHEMA which is just a synonym. For example, in the next screen, we have two schema tabs: We can have several schemas for the same database model in the same way we can have several databases in a MySQL server. It is, in fact, a visual way to define our schema. Every object added in the graphical model also shows up in the physical schema. The physical schema contains all the necessary pieces to define the database: tables, columns, types, indexes, constraints, etc. The next section explains these concepts and how they are related. Having the separate sections for Physical Schemata and EER Diagrams, and the possibility to include several Schemas in one database model may be confusing. The catalog on the right will show every element in our schema, and allow us to drag and drop elements to diagrams if needed. A database model can have several different schemas. We can rename it and use it as our DB schema. When we create a new database model, it contains the default mydb schema. In the data modeling part of the home screen, we click ’Create new EER Model’, and the following screen appears:

One subject may be taught in many classesĪt this point, we have all the information we need to meet the star of this show.

At one particular day and hour, there may be several classes.

One class may have several hours (in a week).

One subject can be taught by many teachers.

When drawing our diagram, we will need to know the relationships between these groups of data as well so we better think about that now! For our little project, we have decided that we need to store the following information: Suppose a group of teachers want to offer online classes for several subjects, using Skype or any other video conferencing software.

To learn how to use MySQL Workbench, we’ll use a very simple database for online classes as an example. Note: this tutorial is based on the Community OSS Edition version 5.2 (5.2.16), currently in beta release at the time of the writing (April 2010). The commercial edition adds some extra functionalities, such as schema and model validation or documentation generation. It’s fully functional, and is the one we’ll be using in this article. The community edition is Open Source and GPL licensed, as you’d expect. There are two different editions: the Community OSS Edition and the commercial Standard Edition.

MySQL Workbench is available for Windows, Linux and Mac OSX. In this tutorial, we’ll focus on the Data Modeling aspect to create a database from scratch, and then have just a quick look at the SQL editor to execute our generated SQL script and create the database within MySQL. Graphic interface to start/stop servers, create user accounts, edit configuration files, etc. Database Administration: Replaces MySQL administrator.Data Modeling: Complete visual database design and modeling.Allows the user to connect to an existing database and edit and execute SQL queries. SQL Development: Replaces MySQL query browser.MySQL Workbench is a powerful tool developed by MySQL with three primary areas of functionality: Specifically, we’ll review how to use MySQL Workbench, a cross-platform, visual database design tool.

In today’s tutorial, you’ll learn how to use a visual database modeling utility to draw a database diagram and automatically generate SQL.
