10 Best Data Modeling Tools To Manage Complex Designs

Explore the Best open source free and online Data Modeling Tools along with their Features:

What is Data Modeling?

Data modeling is the process of applying the techniques and methodologies to the data (data requirements) in order to convert it in a useful form. The process converts complex software design into a simple easy to understand diagram with the data flow.

In simple terms, whatever data we have, in order to store that data in a database, we have to convert it into a certain form (i.e. data model needs to be created). Thus Data Modeling tools will allow you to draw diagrams as it is easy to connect and understand data diagrammatically.

data modeling tools

Data modeling tools help us to create a database structure from these diagrams. Hence it becomes easier to connect data and form a perfect data structure as per our requirement.

Different tools support different operating systems and most of the data modelers support Windows operating system. While a few support Mac and Linux. Also, different tools support different databases.

These tools offer features like the creation of data structure from diagrams, forward & reverse engineering, import & export facility, documentation, support for multiple databases, reporting, etc. Some tools can be used online as well.

Some data model tools can be integrated with big data platforms like MongoDB or Hadoop Hive. These tools can also be called as big data modeling tools. An example of such a tool is ER/Studio.

Data modeling in the warehouse is nothing but using the data models to design the database conceptually, logically, and physically. Similarly, they are used for creating relational tables, primary & foreign keys, and stored procedures.

Logical and Physical models: Physical model, in simple terms, is the real design of the database as per the requirements based on the logical modeling. The selection of the right data modeling tool depends on mandatory features, database support, operating system support, and price of the tool.
