Azimutt features and specs

  • User-Friendly Interface
    Azimutt offers a clean and intuitive user interface, making it easy to navigate and use for both technical and non-technical users.
  • Visualization of Database Schema
    The tool provides effective visualization options for database schemas, enabling users to better understand and manage complex databases.
  • Collaborative Features
    Azimutt supports collaboration, allowing multiple users to work together on the same database project, enhancing teamwork and productivity.
  • No Installation Required
    As a web-based application, it does not require any installation or setup, making it convenient to access from any device with internet connectivity.

Possible disadvantages of Azimutt

  • Limited Offline Functionality
    Being a web-based application, Azimutt has limited offline functionality, which can be a drawback for users requiring non-internet access.
  • Potential Performance Issues
    Performance might be affected when dealing with very large databases or complex schema visualizations, depending on browser and internet speed.
  • Dependency on Internet Connectivity
    As an online tool, users must have reliable internet access to use Azimutt, which might be a limitation in areas with poor connectivity.

PostgreSQL Exercises features and specs

  • Free and accessible
    PostgreSQL Exercises is completely free to use with no registration required, making it highly accessible to anyone who wants to practice SQL skills without any financial barrier.
  • Interactive practice environment
    The site provides a built-in SQL query editor where users can write and execute queries directly in the browser against a real database, getting immediate feedback on their results.
  • Progressive difficulty
    Exercises are well-organized into categories (basic, joins, aggregation, date, string, recursive) and progress from simple to complex, allowing learners to build their skills incrementally.
  • Realistic dataset
    The site uses a realistic country club management scenario with interconnected tables, giving learners practice with a coherent and relatable data model rather than abstract or disconnected examples.
  • Detailed solutions and explanations
    Each exercise comes with a detailed expected result set and a thorough explanation of the solution, helping learners understand not just what the answer is but why it works.

Possible disadvantages of PostgreSQL Exercises

  • Limited dataset scope
    The entire site relies on a single small dataset (a country club with members, facilities, and bookings), which limits exposure to diverse data modeling patterns and real-world complexity.
  • No user progress tracking
    Since there is no account system or registration, the site does not track user progress, making it difficult for learners to pick up where they left off or monitor their improvement over time.
  • PostgreSQL-specific syntax
    The exercises focus specifically on PostgreSQL syntax and features, which may not directly translate to other database systems like MySQL, SQL Server, or Oracle, potentially limiting transferability of learned skills.
  • Outdated design and interface
    The website has a dated visual design and user interface that lacks modern UX features such as syntax highlighting, auto-completion, or responsive mobile support, making it less pleasant to use compared to newer platforms.
  • Limited number of exercises
    The total number of exercises is relatively small compared to other competitive programming or SQL practice platforms, meaning advanced users may quickly exhaust the available problems.

Questions & Answers

As answered by people managing Azimutt and PostgreSQL Exercises.

How would you describe the primary audience of your product?

Azimutt's answer

Azimutt is mainly targeted at developers working with databases, allowing them to easily explore and understand them by either importing the schema or connecting to a live instance.

As it's quite easy to use, we have seen other profile such as product owners, engineering managers and even CFOs using it to better understand the product they build or extract meaningful data on their own ^^

What's the story behind your product?

Azimutt's answer

Early 2021 I joined Doctolib, a health startup very successful in France, and discovered their big Ruby on Rails monolith backed by a large PostgreSQL database with more than 700 business tables (more then 1300 in total). As an architect I worked with several teams and needed to understand their models but neither Ruby, Rails or the structure.sql were very helpful for such a big app. So I looked for a tool but they all failed with such a large database, so after a few month and tens of tools tested, I decided to build my own: Azimutt. Now it has evolved a lot and we are still very active to enable new usages every months. I believe it's a solid product and quite unique ❤️

Which are the primary technologies used for building your product?

Azimutt's answer

From development languages, Azimutt is built with Elm/TypeScript for the frontend, Elixir/Phoenix for the backend and PostgreSQL/S3 as storage.

What makes your product unique?

Azimutt's answer

It's the only ERD able to handle databases with many tables (>1000) nicely thanks to unique features:

  • layouts to see only the relevant tables (not all are useful for everyone)
  • smart search everywhere

It's also very unique in the sense it's made to explore and understand real world databases, from development to production with larges features:

  • database design with an intuitive DSL
  • database documentation, on any table, column or layout (markdown text and tags)
  • database analysis to make sure best practices are in place
  • innovative data exploration

Thousands of developers already love it, give it a try, we have several samples you can try right away!

Why should a person choose your product over its competitors?

Azimutt's answer

Azimutt is the all-in-one app to explore real world databases. If you look for very specialized features some competitors may be more suited, but if you want a versatile app to explore and understand your database, we believe no competitor come close to us.

  • if you have more than 50 tables, there is no match, you should be amazed by Azimutt features built for large databases
  • if you want to mix data exploration and schema exploration, it's also very unique
  • if you care about open source, visit our GitHub

Who are some of the biggest customers of your product?

Azimutt's answer

Azimutt is used at Doctolib (3000 people company) and some other french scale ups I can't disclose yet.

  • pgAdmin Generate ERD stuck on load
    A couple of options here: - From a database. Generate ERD by connecting to your database directly. I've used this as a quick way to generate a diagram from my local or even QA DB (not prod DB for obvious security reasons). - From a schema dump file. Take a pg dump and then generate an ERD from the dump file. There are ERD tools like dbdaddy.dev and azimutt.app that support these options. Source: over 3 years ago
