Προγραμματισμός Βάσης Δεδομένων Jobs

Database programming falls into three categories: maintenance, data processing and programming. The programming portion is the creation of bespoke database for an application that allows for the application to interact with it. The bulk of work for a database programmer however, is the maintenance. Troubleshooting issues, recovering data and providing technical support provide a continuous employment for database professionals.

Processing the data is the importing, organizing and translating of data into the database. The programmer will write scripts to this effect, and perform daily checks on the database. This provides feedback in terms of any maintenance that is required.
