Data Modelling Tools Data modeling is the first step of data analysis. Data modeling is used to understand data more clearly. It helps the modeler to understand all the fields of data and classify them into various groups. It makes it easier to interpret and transform data before executing any complex analysis. Without data modeling, it is very hard to design any further steps for data analysis.”
Data modeling is a method of creating a data model for the data to be stored in a database. It conceptually represents data objects, the associations between different data objects, and the rules.
Data design tools help you to create a database structure from diagrams, and thereby it becomes easier to form a perfect data structure as per your need.
1. Edraw Max’s Database Model Diagram
Edraw Max’s Database Model Diagram is among the best and quickest free and open source tools to create a Database Model Diagram.
It comes with rich, neat, and pre-made shapes that make it easy to complete jobs. The drag-and-drop feature makes the tool user-friendly. The shapes are vector-based, which makes it possible to redesign them. The modeling tool comes with a bunch of advanced and automated functions that make customization easy. This free tool has some paid packages as well for users who want more.
Edraw Max has several entity relationship shapes, view, relationship, entity, parent to category, category to child, category, dynamic connector, strong entity, line connector, strong relationship, attribute, weak relationship, etc.
2. Visual Paradigm
Visual Paradigm comes with a drag-and-drop editor that makes it easy to build apps.
With this tool, you will be able to export the database from Entity Relationship Diagram (ERD). New users can count on the REST API for designing purposes. In case you have trouble, you can count on the brilliant wizard that provides step-by-step instructions on how to make a database.
One of the highlights of this data modeling tool is the collaboration feature that allows team members to work on a project simultaneously.
With Visual Paradigm, you will be able to build reports. Plus, unlike some other tools out there, it works on almost all operating systems including Linux, macOS, and Windows.
3. SPSS Amos
You might be surprised to see IBM SPSS on this list. After all, it is best known as a powerful structural equation modeling tool designed to help during the research process by extending standard multivariate analysis methods such as regression, correlation, variance, and factor analysis.
However, very few people know that SPSS Amos doubles as a data modeling tool. Amos offers intuitive drag-and-drop functionality. Marketed as a paid tool, it’s available for free for most students who can get access to it via university.
There’s PSPP for those who want a free, open source version of the app.
4. isee systems
This powerful tool charts, diagrams, and makes use of animations to help learners discover relationships between a variety of variables.
The drag-and-drop functionality makes it fun to use. This tool can handle sensitivity, simulation, and time series models.
While it’s a paid tool, you can get your hands on a free trial to know more about how it works.
5. ER/Studio
