Databases
Database courses on SQL, data modelling, PostgreSQL, Oracle and Redis. Compare topics, levels and practical focus, then enquire about training.
Databases include courses on queries, data models, administration and performance of relational and in-memory storage systems. The topics suit analysts, developers, database administrators and specialists who want to analyse data themselves. As an entry point, use “SQL & databases”. If you design structures, choose “Relational data modelling”. For operations and monitoring, there is “Administering and monitoring PostgreSQL”. Decide by task: query, design or operate. Product names such as PostgreSQL, Oracle or Redis refer to technologies and imply no partnership. Prerequisites, scope and dates are confirmed on enquiry.
