Best data modelling tools

Data is fast becoming one of the most valuable assets at the disposal of any organisation, regardless of sector, and is proving crucial to keeping operations running smoothly. To make the most of the data that’s gathered, however, businesses must ensure they’re using the right tools to gain genuine insights that will improve the quality of decision-making.

Data modelling platforms are one of the most important services in any business’ arsenal as they wrestle with the volumes of information they gather day by day. This type of software works to turn mountains of facts and figures, devoid of any meaning, into meaningful trends and patterns with relevance. They process data and regurgitate it as information that’s easy to understand and digestible, with the aim that these insights will, in turn, feed decision-making to improve long-term business performance.

There are various options available - each differing in purpose and scope - although all modelling tools are normally applied in the form of a broader database management system. These platforms also handle specific data variants carefully to ensure that correct processes are built with only the most relevant pieces of data. They may also produce reports for key individuals across the wider businesses, in the best-suited format.

Essentially, data modelling platforms are designed to increase the speed by which a business can master all the data it processes. However, there are minor differences between the most popular pieces of software on the market. We’ve compiled a list of the most widely-used tools that businesses can use and the key differences between them.

Lucidchart allows data to be modelled visually and collaboratively. It's a pretty flexible web-based programme and allows for a whole range of different models to be created, including system design, brainstorming, project management and more. There are plenty of templates and libraries available to make your datasets look professional with little effort.


How to maximise the value of your data and apps with IaaS

Free yourself from infrastructure complexity


Lucidchart is also well-priced, making it a very competitive alternative to SmartDraw. There are, however, different levels of licence - free, Basic, Pro and Team, each offering different usage limits, depending on how many users will need access and how often you need to create models. For example, the Basic account offers unlimited shapes and documents, with 100MB storage, while the Team offers access to multiple users and team management, plus import and export from Microsoft Visio and AI features.

It uses a simple drag and drop interface that makes it an effective solution for the majority of use cases. Re-sizing objects is a breeze and moving objects around comes as second nature, making for a very intuitive user experience.

The only drawback of Lucidchart is that it's only available for use via a web interface rather than a desktop application, making it a little clunky and reliant on a web connection to function.
