MySQL database design for systems that have to stay correct

MySQL is a relational database and it is the database behind most of our ERP and POS systems. In a business system the database is not an implementation detail — it is the record. If the data model is wrong, no amount of good interface code will save the project.

How we approach schema design

• Model the business, not the screens — tables follow how the company operates: branches, warehouses, customers, and document relationships. Changing the interface should never require restructuring the data.
• Transactions for money and stock — a sale, its stock deduction, and its ledger entry commit together or not at all. This prevents impossible states like negative stock or unbalanced accounts.
• Constraints in the database — uniqueness and referential rules enforced by the database rather than only by application code.
• Indexes matched to real queries — we index for what the system actually queries, instead of indexing everything and slowing writes down.
• Safe migrations — schema changes are versioned, reversible, and rehearsed on a copy of production data first.
• Adequate backups — automated backups with a tested restore. A backup never restored is a hope, not a plan.

When a database needs replacing

MySQL is the right choice for the vast majority of the systems we build, and it handles very large volumes when designed and indexed properly. We will tell you when the answer is better indexing rather than a more fashionable database.
