Your Database Is the Foundation Everything Else Depends On
You can rebuild a frontend in a few weeks. You can swap a framework with enough effort. But your database — the structure, the relationships, the years of accumulated business data — is the one part of a system that is genuinely hard to change once it is established. A poorly designed data model creates problems that compound with every feature added on top of it. Slow queries, data inconsistencies, painful migrations, and reporting that requires workarounds instead of simple queries. The database is where shortcuts cost the most, because they are the hardest to undo.
We work with two database systems — PostgreSQL and MySQL — and we choose between them based on what the project actually needs. PostgreSQL is our primary database for new builds. Its support for advanced data types, JSON columns, full-text search, complex querying, and transactional integrity makes it the stronger choice for custom software where the data model is non-trivial. MySQL is widely deployed across WordPress sites and legacy systems, and we maintain deep expertise in it because many projects involve working with existing MySQL databases rather than starting fresh.
Both systems are relational databases at their core, and good database design matters more than which engine runs it. We focus on data modelling — getting the tables, relationships, indexes, and constraints right from the start — because the data model is the part of a system that most directly determines long-term maintainability. A well-modelled database makes features easier to build, queries faster to run, migrations safer to execute, and reports easier to produce. A poorly modelled one creates friction in every part of the application that touches data — which is every part.
Our own products demonstrate the depth of our database expertise. The Client Dashboard runs on a dual-database architecture: PostgreSQL for the primary application data and a separate database for lead and contact data. The Beacon product suite manages shared authentication, cross-product entitlements, and subscription billing across seven products, all backed by database structures we designed and maintain. We write SQL directly for complex queries and reporting, not just through ORM abstractions — because understanding the database at the query level is what separates applications that perform well from applications that need apologetic loading spinners.
What We Cover
- PostgreSQL — our primary database for new applications. Used across our own platforms and most client builds. Advanced querying, JSON support, full-text search, and reliability under complex workloads make it the right choice for systems with non-trivial data models. When the data is the core of the application, PostgreSQL handles it properly.
- MySQL — widely deployed and thoroughly understood. Used in WordPress environments, legacy systems, and projects where MySQL is already established and migration would add risk without adding value. We maintain and optimise MySQL databases that have been running for years across numerous client environments.
How Databases Connect to the Rest of the Stack
Databases sit beneath everything else in the technology stack. The Frameworks section covers Laravel and the other application frameworks that interact with these databases. The Programming Languages section covers SQL alongside the other languages we use. And the Infrastructure section covers where the databases are hosted and managed in production.
If you are planning a data migration — moving data from a legacy database, consolidating multiple data sources, or switching database engines — the Legacy Systems section covers migration strategies, and How to Plan a Data Migration provides the planning framework.
Where to Start
If you are starting a new project, PostgreSQL is likely the right choice — it handles complex data models better and gives you more capability as the system grows. If you have an existing MySQL database or a WordPress-based system, MySQL is where to look. If you are unsure, database selection is one of the decisions we help clients make during the planning phase — get in touch and we will advise based on your specific situation.
