Database Administration
For PHP developers, roles requiring database administration (DBA) skills involve managing, maintaining, and optimizing the databases that power their applications. While larger companies have dedicated DBAs, in many agile or smaller teams, developers are expected to handle these responsibilities. This includes ensuring the database is performant, secure, and reliable, directly impacting the overall application's health.
Typical DBA Tasks for a PHP Developer
Common database administration tasks include designing scalable database schemas, implementing and managing migrations, and optimizing slow queries by adding appropriate indexes. Developers may also be responsible for managing user roles and permissions, configuring database servers, monitoring performance, and setting up automated backup and recovery plans. This skill set is especially valuable in DevOps and full-stack environments where developers have end-to-end ownership of their features.
