Database Programming Jobs

Database Programming is an essential software development skill that processes data and stores it in a database. Database Programmers store and handle databases, create, maintain and update them so that data is organized, secure, and easily retrievable when needed. Database programming relies on the manipulation of an underlying language, like SQL, through coding structure and automation of rules to ensure accuracy and enforce consistency.

Whether you’re in need of organizing a complex amount of data, validating data changes, or writing to multiple databases at once, a Database Programmer can be your best asset when it comes to optimizing and automating your current system.

Here's some projects that our expert Database Programmer made real:

  • Data Management - whether it’s relocating large files from one server to another or editing large chunks of data.
  • Seamless User Experience – extending automations for a better end user experience with less manual labor.
  • Security – tying all transactions for protection from cyber threats and potential malicious activities.
  • API Connections – Pulling real-time data with API calls to update various databases with the most updated information.
  • Optimization – Configuring underlying structures such as indexing algorithms that can be modified over time to match user demand.

Database programmers are highly specialized software engineers with expert knowledge in both backend development and databases themselves. They rely on a combination of inherently acquired knowledge through technical education or career experience to make sure data processing is secure, accurate, fast and consistent. With help from a Database Programmer, clients can easily optimize their systems so they are able to access information quickly while still keeping their businesses secure and up-to-date.

As a result, working with a Database Programmer on Freelancer.com is ideal for those who need real-time solutions tailored to match their unique needs without compromising security or efficiency. No matter the complexity of your business’s needs and your data requirements, our freelancers are experienced in setting up the perfect custom-made solution for you. Post your project now and get started on your business’s journey today!

    I need some help with a data model I created in Power Pivot. I have 2 data sets: one is Sales and the other is Stock. I have added both data sets to my data model and am now trying to create a pivot which pulls data from both tables. My Sales table pulls the data perfectly but the Stock table does not. Some context... When I pulled the data into the data model I added a column which I called DataModelLink. This created a 1 (Sales) to many (Stock) relationship between the two tables. As an example, I tried to pull the data of one particular style which had one line in the Sales table but 2 lines in the Stock table. For this reason, my Pivot is only reading one of two of the lines on the Stock data table. I am happy to share the data model as it is only sample data.
