Data modeling is defined as the central step in software engineering that involves evaluating all the data dependencies for the application, explicitly explaining (typically through visualizations) how the data be used by the software, and defining data objects that will be stored in a database for later use.
How Data Modeling Works?
Data modeling is the process of making a visual representation of all or part of an information system to show how different data points and organizational structures are linked. The goal is to explain the different types of data that are used and stored in the system, how different types of data are connected, how data can be grouped and organized, and what its formats and features are.
When making data models, business needs are taken into account. Rules and requirements are designed with the help of feedback from business stakeholders before they are added to the design of a new system or changed during an iteration of an existing one.
A data model is similar to a flowchart since it visually represents how data entities are related, their various attributes, and the nature of the data entities themselves.
Thanks to data models, data management and analytics teams can discover mistakes in development plans and describe the data requirements for apps, even before any code is created. As an alternative, data models can be produced by efforts to extract them from current systems through reverse engineering.
Data modeling is a crucial IT discipline for any organization. When building an app, it depicts 360-degree data dependencies and preempts bottlenecks. It helps maintain data-driven cloud services like e-commerce and provides better user experiences. It also keeps enterprise data repositories up-to-date so that you can extract the most valuable insights. By knowing the different types of data models, data modeling techniques, and best practices, one can unlock its full potential.
Data Modelling is very usefully implemeted in Apache AGE and AGE Viewer project:
