Top 10 Database Design / Modeling Tools in 2021

Top 10 Database Design / Modeling Tools in 2021

Data modeling involves establishing a model for the data that will be kept in a database. Data modeling aids in the organization of data and clarifies what data is required. A conceptual model is built, and data relationships are established with this tool.

In addition, it aids in the visual depiction of data and enforces corporate standards and government laws on the data. To assist the business processes in companies, data modeling identifies and evaluates the data requirements.

Besides representing data items, it also represents connections between data objects and rules.

A company or application’s data model is never complete. It is more accurate to think of it as a document that will evolve as the business changes. Techniques such as data modeling are used to provide additional information about a product or service.

As the name suggests, it involves drawing a relationship chart for information that will be kept in a database. Thinking about the main data pieces that need to be saved and retrieved and how they need to be grouped highly helps, doesn’t it?

What are the benefits of data modeling

Why do you need data modeling, now that you know the definition of the words Data Modelling and Data Models? When designing our final year project right before graduation, one way to avoid howlers would be to avoid them. The following are the core reasons why data modeling is needed in a more formal way:

  • A data model aids in the efficient and optimal architecture of the database.
  • All the data items utilized in an information system must be accurately understood and accounted for.
  • A data model outlines the tables that must be included in a database, as well as the primary keys and foreign keys, as well as the many constraints and tests that must be in place for the database.
  • This guarantees there are no duplicate values in the table(s) as well as constant access to essential data. Database tables are not left with blank values, therefore avoiding the repetition of data.
  • If you have a detailed data model, you’ll know exactly what your database will look like when it’s finished.
  • To scale up an application for wider use in more complex and sophisticated business scenarios, one might resort to a data model for guidance.

Later difficulties

Having seen why data modeling is so important, let’s look at some of the difficulties that still exist even after a data model has been implemented, as well as some of the challenges that arise after a data modeling effort has been completed.

  • Modelers frequently focus on data objects while modeling data in a modeling tool. And physical data stored in these objects may be missed.
  • As a result, data modeling is a time-consuming procedure that requires subject expertise.
  • Changes to a data model, no matter how little, will need changes to the database as a whole. This compromises the availability and performance of the system, resulting in a large downtime of the application.

Before building a database for an application, data modeling is essential, but it comes with its own set of problems that must be considered while developing a data model for an application. Even professionals in the area find data modeling to be a tiresome task, but there are methods to make it easier.

One of these is by using data modeling tools available on the market. This part will examine the data modeling tools accessible to us in further detail.

Top 10 data modeling tools

1. Erwin Data Modeler

Erwin Data Modeler

It’s been around for around 30 years. The fact that Erwin understands data and data modeling is enough for us to recommend it. In addition to defining the data architecture, this tool guarantees continuous integration with databases such as MySQL and PostgreSQL to view your data and make the most of it.

  • Comparison tools that are robust
  • Multiple versions are available to meet the unique demands of the customer.
  • Detailed visualizations with metadata

Erwin offers a variety of variants, each with its own distinctive features. Model creation and deployment are included in the basic edition. Data may be seen using the navigator, which is a read-only version of the application. For collaborative work, the workshop edition is a repository-based solution based on GitHub. The NoSQL version is the most specialized tool, as its name implies.

It is possible to compare various databases or versions using both the regular version and the workshop version’s comparison features.

Pricing: $299 a month or $2,999 a year for the standard edition of the program. The workshop edition costs $449 a month or $4,499 a year.

2. DbSchema


Database builder and management DbSchema supports SQL, NoSQL, and Cloud databases.

DbSchema, for example, offers:

  • Bug fixes and platform updates are performed on a regular basis (every 2 or 3 months)
  • SVN, Mercurial, and CVS are all supported in addition to GIT.
  • A random data generator is built-in to the application.

DbSchema, on the other hand, does not provide adequate information about the fields and does not offer version control capabilities. The tool is also said to be less trustworthy than other tools by its users.

Individual users can purchase a permanent license for $127, starting at $63 for one user (for academic purposes). On request, evaluation licenses can be obtained.

3. ER/Studio


It has both the positives and negatives, like Erwin. This software is known for its strong feature set, which is the result of decades of advancements. However, ER/Studio struggles to stay up with emerging technology.

  • Mindset centered on business is essential.
  • Integration of Git with tools for merging and comparing code
  • Engineers with forward and reverse capabilities

To make it easy to use, the Git integration uses SSIS and SSRS standards to make it contemporary and effective. A key goal of ER/design Studio was to bridge the gap between business and developers so that you can procure the most out of your data.

You may utilize ER/Studio whether you already have data or are beginning from scratch. Additionally, the tool will assist you in reducing redundancy. Generally, costs are negotiable but start at $1470.40 per user (workstation).

4. HeidiSQL


A free and open-source tool for modeling physical layers of data, HeidiSQL was created to be easy to use. HeidiSQL is the most popular MySQL and MariaDB tool in the world since it is free. HeidiSQL is capable of connecting to many databases simultaneously.

SQL Server, MySql, and PostgreSQL are all available!

There are no distinguishing qualities that set it apart from its competitors who are using proprietary software. In spite of these shortcomings, customers report no harmful consequences and just a restart.

Costs: None

5. ERBuilder


It is the goal of the ERBuilder Data Modeler to make data modeling accessible to developers. A conceptual or logical layer of data modeling cannot use it.

  • Reverse and Forward engineering of databases
  • Easy to utilize visual data modeler
  • Data exploration

ERBuilder, on the other hand, lacks facilities for collaborative work and versioning management. A significant point in its favor is, however, the comprehensive and easy-to-use graphical user interface. Users of ERBuilder will enjoy the ease of navigating between tables and the automated creation of comprehensive diagrams with the press of a button.

Prices range from a free edition to a $49 subscription plan to a $99 permanent model.

Navicat Data Modeler

With a highly appealing user interface, Navicat Data Modeler is both cheap and capable as a data modeling tool. Navicat, on the other hand, appears to be a cutting-edge data modeling tool.

Erwin and ER/Studio are examples of expensive data modeling tools.

  • Physical and Conceptual as well as Logical modeling
  • Reverse engineering tools
  • Navicat Cloud

There are fewer features in Navicat than in Erwin and ER/Studio. However, some users have complained about the absence of field explanations in Navicat.

Users of Windows, macOS, and iOS devices can use the Navicat cloud to synchronize connection settings, query results, and model data.

Pricing: Starting at 22.99 per month, depending on the length of the contract.

7. Archi – Open Source ArchiMate Modelling

Archi - Open Source ArchiMate Modelling
