It is a conceptual representation of Data objects, associations between different data objects, and the rules. Data modeling helps visualize data and enforces business rules, regulatory compliances, and government policies on the data. Data Modeling ensures consistency in naming conventions, default values, semantics, and security while ensuring the quality of the data. Data Modeling tools are the software applications that help you to create database structures from diagrams, and thereby it becomes easier to form a perfect data structure as per your need.
These tools allow users to create business-specific infographics, diagrams, data visualizations, and flowcharts. Skip to content. You should consider the following factors while selecting a database modeling tool: User Interface and Navigation Scalability Functionalities offered Visualization and reporting features Integration with other tools Pricing Support Customizations Collaboration features.

That is why it is used to define and analyse data requirements that are essential for supporting the business processes which is a part of the information systems of companies.
The process, therefore, requires the close and active collaboration of professional data modellers, stakeholders as well as prospective users of the information system.
From requirements of data to creation of actual database, three different types data models are produced. Initially, the data requirements are recorded as a conceptual data model which is basically a set of technology independent specifications that are used to talk about the initial requirements of data.
Post this, the conceptual model is converted into a logical data model that documents the structure of data, which is then implemented into databases. Multiple logical data models maybe be needed to implement a single conceptual data model. The last step involves the transformation of logical data model into a physical data model.
In this model, data is organised into data and creates accounts for access, performance and storage details. This means that data modelling defines data elements as well as the structure and relationships between the elements. Used to model data in a systematic and proper manner, data modelling techniques helps companies to manage data as a valuable resource. It, therefore, goes without saying that data modelling standards are essential requirements for companies that conduct projects, where data has to be analysed and defined in a particular manner.
This post highlights some of the important data modelling tools that go a long way in help making data modelling a successful and effective endeavour for various brands and organisations. A free and open-source visual modelling and design tool, Archi is used to create models and modelling sketches.
Initially funded by Jisc between , Archi was a part of the national project that helped to support a programme of the Enterprise Architecture in the higher education sector of the United Kingdom. This data modelling tool supports the ArchiMate 2. The 2. By supporting modelling, visualization, analysis and documentation of enterprise architecture from multiple viewpoints and with multiple views, BiZZdesign Architecture also supports automatic data collection along with data import from office applications.
This data modelling tool intends to offer clients a high-value enterprise architecture data modelling tool that can be controlled by business management. In addition, it was recognised as a notable enterprise architecture tool by Garter and Forrester in Another software tool for is, CA ERwin Data modeling is used for developing custom made information system including data charts and databases for transactional systems, besides data requirement analysis and database design.
Based upon the IDEF1X method, this tool also supports diagrams displayed with information engineering notation. Drag and drop the shapes and you can even redesign them because they are vector-based. It is the easiest-to-use drawing software. This tool integrates database design and creation, modeling, maintenance, and maintenance in a seamless environment.
The interface is extremely user-friendly. DBDesigner is a powerful open-source data modeling tool that can create a visual model for any database. Open ModelSphere is an open-source business process and open source data modeling tools. It supports English and French user interfaces.
It can be used for complex conceptual and logical data modeling as well as physical design database modeling. It is now a highly professional tool, supported by an extensive community of software engineers and architects.
