  • Use the reverse engineering function to create a logical and physical model by extracting information from an existing data source.
  • Example: Search smith , will return results smith and adamsmith.
  • We normally build a physical database from the ER diagram — this is called forward engineering.
  • By visualizing a database schema in ERD , you can re-edit it and patch changes back to the database, or you can produce a data specification that acts as a reference for programmers who need to access the database.

We normally build a physical database from the ER diagram — this is called forward engineering. But there are times when you want to do the opposite — create diagram from existing database schema. This task is called reverse engineering , as you first have working tool and you create model from it. Since reverse engineering is converting live database schema into model , we need to understand how models work in MySQL Workbench. Models are a separate entity from the databases you are connected to and are stored locally on your disk.

Schema is a grouping of database objects - tables, views and routines. It is the same as schema in MySQL database or other databases. By default each model has empty mydb schema. You don't need it and it can be deleted. Model can hold multiple ERD diagrams.

Diagram can contain elements tables, views, etc. To reverse engineer database go to menu Database and choose Reverse Engineer Provide connection details to your database and click Next.

Wait for the connection and click Next again. When successfully connected wizard will show you list of available schemas on the server. Select the ones you want to reverse engineer. Wait for the schemas being read and continue with Next.

On next screen you have an option to select object types and filter specific objects. Let's ignore it and import all objects. Wait for reverse engineering to take place and when done continue with Next. Final screen shows you a summary of the import. Close with Finish. Piotr Kononow Table of Contents:.

What is Reverse Engineering? ER diagrams are a useful tool for understanding and modeling and design of databases. Physical Schemas Schema is a grouping of database objects - tables, views and routines.

Diagrams Model can hold multiple ERD diagrams. Reverse engineering To reverse engineer database go to menu Database and choose Reverse Engineer Results: the model When the process ends with success you get a new model see above for more details with: physical schemas with database objects imported from the database default ER diagram with all the tables and views from all imported schemas What next?

Once you have model from physical database you can use it in various ways: Print diagram and share it with colleagues Put on a wall and look at it while drinking coffee Apply changes and push them to the database forward engineering Use it for better and quicker reporting Analyze it before applying any changes to the database.

Reverse Engineering ERD from Database

Visual Paradigm supports reverse engineering ERD from existing database. By visualizing a database schema in ERD, you can re-edit it and patch changes back to the database, or you can produce a data specification that acts as a reference for programmers who need to access the database. Besides, Visual Paradigm automates object-relational mapping, object model can thus be generated from the data model produced by reverse engineered. Database design and engineering Chapter 3. This opens the Database to Data Model window.

The Data to Data Model window In the Database to Data Model window, set the language, which is the method to use in connecting to your database. By selecting C , adapter file will be used. If you are uncertain about this option, just leave it unchanged. Select the Result, which is the post-action of database reversal.

Here is a list of available options: Result Description Popup entities tree You will be presented a window with reversed entities listed. You can form ERD s manually by dragging and dropping entities from that window onto diagram s.

Form a new diagram with the reversed entities Automatically create an ERD and place all the reversed entities in it. Make sure you are clear about the amount of entities that will be reversed and the complexity of diagram that will be formed. Having too many entities on one diagram may result in a poor database design that is hard to read and maintain.

Again, make sure the amount of entities to be reversed and the complexity of diagram is under your control. Do not form diagram with the reversed entities Just produce entities without visualizing them with any ERD. You can visualize them later on if you want to. List of available results of database reversal Sometimes, you may just want to reverse engineer stored procedures or triggers.

If that's the case, uncheck Reverse Table. Synonym is an alternative name for objects such as tables, view, etc. If you are going to reverse an Oracle database, you can optionally check Include synonyms to reverse synonyms as entities.

By checking Group stored procedures and triggers in one shape , we will create at most one stored procedures shape and one triggers shape to hold all the reversed procedures and triggers. When unchecked, one procedures shape will be created for each procedure being reversed. You can also place the reversed entities into a dedicated model by clicking Click Next.

Configure the database connection and click Next. Make your choice and click Next. Skip this step if you aren't prompted to select schema. Select schema By default, all database tables in the specified database or schema will be reversed. Select tables to be reversed Preview the entities that will be created and click Finish to execute the reversal. Preview the entities to be created When finished, you can optionally form an ERD from the reversed entities.
