Veelgestelde vragen
Can you speed up slow queries in an existing database?
es. I read the execution plans with EXPLAIN, fix indexes, rewrite joins and subqueries, and adjust the schema where it is the real cause. You get each query's timing before and after.
What do you need from me to start?
A short description of what the system stores (customers, orders, bookings...), the queries or reports that matter most, your database engine if one is already chosen, and any existing schema or dump. If you have none of that, a list of the screens or features is enough to begin.
MySQL or MongoDB: which should I use?
It depends on your data. Relational data with strict consistency (payments, inventory, bookings) usually belongs in MySQL. Flexible, nested or fast-changing documents can suit MongoDB. I recommend one with reasons before any work starts, and sometimes it is both plus Redis.
