A data model represents the collection of data stored in a database. Data modelling reduces the complexities of a database design and organises data for various users. Learning about some tools to model data can help you create effective models for analysing large amounts of data. In this article, we learn what data modelling tools are and explore some popular ones to help you model and analyse data effectively.

What Are Data Modelling Tools?

Data modelling is a labour-intensive and time-consuming process, but by using data modelling tools, analysts can quickly and efficiently model data. These tools allow analysts to ensure that all the databases represent the data objects accurately. An efficient tool can help the data analyst to design databases that are less likely to experience failures and are quick to execute. An excellent tool also ensures non-redundancy, reusability, stability and flexibility of data.

14 Data modelling tools with their features

Here are some popular tools to help you model data efficiently:

ER/Studio

ER/Studio allows you to model data and turn it into implementable designs. Constructing, tracking and sharing data models is easy with this tool. Analysing data and reducing redundancies in datasets is a strong feature of the ER/Studio. You can integrate it with Git, an open-source distributed control system. It offers logical and physical modelling and helps you develop enterprise data models along with representing business concepts documentation of attributes and relationships. Process model creation, process validation, round-trip database support and data lineage visibility are some of its advanced features.

DbSchema

From schema management to schema documentation, with DbSchema, you can document complex databases easily. Organising tables in multiple layouts and adding comments make the data modelling process efficient. It works with both Structured Query Language (SQL) and non-SQL databases. Its SQL editor, which offers syntax highlighting, text auto-completion, execution of queries and scripts and a graphical execution plan, also defines its robust performance. It also allows the analysis of old and unprocessed data with the help of data uploads from spreadsheet files.

erwin Data Modeler

Finding, visualising, designing, deploying and standardising enterprise data assets are some tasks that you can perform easily with erwin Data Modeler. The tool efficiently manages data, metadata and big data. It allows you to generate data models and database designs automatically, which adds to the efficiency of data modelling and minimises the scope of errors. It is a cost-effective data modelling solution, which features automation and standardisation of data definitions and structures. With forward engineering and reverse engineering of database code and model exchange, it offers a robust enterprise database management experience.

pgModeler

pgModeler's intuitive interface makes the process of creating and editing a database model simple. In this open-source tool, you can even change and redistribute the source code. It allows you to use the plug-in development interface and develop your own extension for the tool. With it, you can export your models to an SQL script, a PNG image, an SVG file or directly to a PostgreSQL server. With its reverse engineering process, creating models based on existing databases is also easy. Its ability to restore work also defines its efficiency, in case you accidentally quit the program.

HeidiSQL

HeidiSQL is a free data modelling tool with which you can create and edit tables, views, stored routines, triggers and scheduled events. It allows you to connect to multiple servers in a single window. MariaDB, PostgreSQL, MySQL and SQLite are some of the database systems the software supports. You can export data from one server or a database directly to another server or a database. Its vast export options for table rows include comma-separated values (CSV), HyperText Markup Language (HTML), Extensible Markup Language (XML), SQL, LaTeX, Wiki Markup and PHP Array.

DeZign for Databases

Visualising the structure of a database plays a crucial role in understanding it better. With DeZign for Databases, you can not only visualise database structures but also reverse engineer existing databases for their easy modification, documentation, analysation and optimisation. This program utilises entity relationship diagrams (ERDs) and enables you to graphically design a database. Offering a display of model information at various levels, this data modelling tool helps you communicate model information abstractly. Its pan and zoom functionality also adds to the ease of use. Some of its advanced features include many-to-many relationships and inheritance.

Archi

Used by enterprise architects, the Archi modelling toolkit is a cost-effective program that supports the description and architecture analysis and visualisation across business domains. Refining a model with properties defined by users and colouring diagrams with your own colour scheme make this program intuitive. It offers a Hint View feature that helps you understand a specific element. Its Visualiser option displays the elements of a model and its relationships with other model elements using a radial-tree graphic. This cross-platform tool offers a Sketch View to help you quickly illustrate your ideas.

Whatagraph

With the help of Whatagraph, you can aggregate data from several sources alongside creating visual representations of their data models. The tool's easy-to-use and editable drag-and-drop interface help non-technical users to create effective data models and determine meaningful conclusions. You can also integrate Whatagraph with several external data sources, like analytics tools, social media platforms and e-commerce portals.

ERBuilder Data Modeler

If you are looking for a data modelling tool to graphically design databases, then ERBuilder Data Modeler is an efficient tool to do so. It uses entity-relationship (ER) diagrams and produces the most popular SQL databases automatically. By visualising the structures of physical models in this tool, you can better understand databases and create new tables along with modifying, analysing and optimising solutions. With this tool, you can list all the tables in a database, navigate from one table to another quickly and create ER diagrams in an interactive manner.

SqlDBM

A cloud-based tool for data modelling, SqlDBM allows you to develop your database from any browser. This program incorporates database rules and objects, like database keys, schemas, indexes, column constraints and relationships. Creating conceptual, logical and physical entity-relationship diagrams (ERDs) is easy with SqlDBM. It also allows you to visualise an existing database and use reverse engineering to graphically represent them. With this tool for data modelling, you can easily identify, develop and standardise data assets across several domains of an organisation.

RapidMiner

Frequently used by both beginners in the field of data modelling and experienced data scientists, RapidMiner allows you to analyse highly complex data efficiently. For beginners, the tool offers a wide variety of tutorials and pre-set case templates. With these, they can easily build their data models and assess results. Data scientists can use the tool's native algorithms and functions to efficiently work with data, and the tool also supports software integration with R and Python programming languages.

Toad Data Modeler

Toad Data Modeler is a helpful tool for you to visualise the structures of databases. Using this tool, you can better understand existing databases and relationships. The tool offers options to easily create logical and physical data models along with reverse engineer functionality to view existing database structures as diagrams. You can even migrate data structures across database platforms and generate in-depth hyperlinked reports on existing database structures in multiple formats, like HTML and Portable Document Format (PDF). This may be a great tool for small and medium-sized companies, wanting to use data to improve their operations.
