Old Delphi systems with Paradox or BDE often appear at first glance to be purely a database matter. In practice, however, reports, forms, permissions, local special tables and processes that have evolved over years are tied to them.
A migration to MariaDB or another modern database is worthwhile when data consistency, multi-user operation, deployment and extensibility need to be made viable again. Crucial is not only the technical target server but the controlled transfer of the existing logic.
We therefore treat tables, indexes, SQL paths, character sets, transactions and historically grown special cases as a cohesive modernization package. Only in this way does a database change become a technical foundation for further steps such as REST, services or portals.
Especially for long-used applications, a phased approach is often more economical than a Big Bang. Precisely planning these interim stages cleanly is ultimately what makes the difference between a successful migration and hectic follow-up work in operations.
