21 Best Data Modeling Tools In 2020


At present, data has become the new currency in the business world. With the increased data churning, the adoption of data modeling tools has also increased. Every organization is adopting data-driven decision making in their business operations. Every action online generates data, from browsing through google, scrolling down Instagram feed, to purchasing groceries online, and this data is beneficial for businesses in understanding user patterns. These data points are collected by organizations and are stored in a database for using them to generate insights that are helpful to make smarter business decisions.

The data sets collected by organizations are converted into data models. Data modeling is the process of creating data models for the collected data sets in order to store them in databases. Conceptually, data modeling represents the data objectives, the connection between various data objectives, and the rules. Data modeling is successfully executed with the help of data modeling tools.

Data modeling tools help data science professionals visually present the databases in graphs and diagrams. This process allows business owners and stakeholders to understand the business processes and clarify business needs and requirements.
