Programiranje podatkovnih baz 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.

    Visualization of shareholding data. 6 dni left
    VERIFICIRAN/A

    I store data in the DB on Users that hold shares and/or directorships in companies. Based on the shareholding data in the database (who owns which shares and how much), a visualization is created. In most cases it's very simple, just a single relationship between a single person and a single company; the owner then owns 100% of the shares of that company (entity); however, sometimes there may also be a holding company in the middle. So a person holds shares in the holding company, and that holding company then owns shares in multiple operating companies. In some extreme cases there will be very complex relationships. There is existing software to visualize this. I believe Neo4J / Neo5J is one of those, but maybe there is also open-source / free software out there that can be used. ...

    Development of a mobile application similar to the Brazilian "Ifood". I need it to work perfectly from the first version. The difference from the application mentioned above is that this application will have small customizations made by users. User moderation should be possible. Finally, the application will have to have hosting large enough for users to have their own pages (such as Facebook's markeplace or Brazilian "Ifood"). OBS. I have a prototype made by me in "Figma" program/software it should serve as an inspiration for both the graphics and the flow control).
