If you have a serious business and a large client base, you will probably need database design services. These companies use database design tools like database design software.

What type of database design tools and database design software are database designers and developers using when seeking to create and maintain database structures effectively.

The most important features they would seek would be:
- editable forms, scriptable objectives
- support for different databases
- reverse engineering
- user-friendly GUI and modeless dialogs
- undo/redo
- conversion from a logical to a physical world
- generation of RIF and HTML documentation
- model merge/model update
- generation of Alter scripts
- entity relationship diagrams.

What are entity relationship diagrams with respect to database design software?

If an ER Diagram is graphically well-arranged it is easy to create as well as maintain the database structure. In the models, all the:
- entities
- domains
- attributes
- foreign keys
- primary keys
- constraints
- descriptions
- indexes
- relationships
- notes
- other logical and physical data
will be ordered transparently. While you crate a model there will be a perfect view of all the elements of the database.

You need to choose database design software that supports
- procedures
- functions
- views
- triggers
- packages
- object types
- object type bodies
- package bodies
- synonyms and sequences
- etc.

How do you reverse database structures that already exist?

The process of reverse engineering will extract the:
- entities
- relationships
- attributes
- triggers
- indexes
- procedures
- other objects
of the database – depending on the specific database.

Depending on the database design software, not all databases support all features. However, a good database design software should be able to work with different databases as well as being able to use different communication methods.

The benefits of reverse engineering
- You can create very detailed RIF and HTML documentation. You can create documentation of a database structure that exists already.
- It’s possible to redraw the structure of the database.
- You can put the model into the inner version manager.
- You can regenerate new SQL scripts.
