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.Hire Database Programmers

I am having problems with displaying data generated from API calls. To talk you through the user journey of the app see below. (attached is a schema and one of the tables and an error message). I have an array of `orders` objects across some tables, filtered by `tracker_status` (not started, in progress etc). It contains number id values (i.e. foreign keys) for other objects (e.g. (task => == order.work_task_id ).name). I think the current architecture is causing problems to provide the name, and possibly causing memory leak.
