In this article, we’ll explore more about the main responsibilities of database developers, salary expectations and market trends. We’ll also look into tips and strategies to identify top-tier database professionals for those hiring managers looking to expand their teams. 

What is a Database Developer?

A database developer is a specialized IT professional responsible for designing, creating, and managing databases. Their role involves structuring data in efficient ways, writing code to build and maintain these databases, and ensuring data security and integrity. 

The role of database developers has gained relevancy over time, suggesting an exponential growth in global data creation and usage. For instance, according to Zippia, the projected growth rate for database developers is 21% from 2018 to 2028. 

9 Top Skills to Look for In Database Developers

When looking for database development essentials, there are a few skills that are a must-have. Whether you want to hire Database experts or looking to become one, these 9 skills are key for effective database development and management: 

  1. SQL Proficiency – SQL programming skills are a priority to look for in database developers. For starters, developers use SQL (Structured Query Language) to interact with the database, including querying, updating and managing data. Being proficient in SQL is what allows developers to retrieve and manipulate data stored in relational databases. 
  2. Database Design – Database developers need to be skilled in conceptualizing and implementing the structure of a database. For this, they need a deep understanding of how to best organize data and define tables, columns, data types, and relationships between tables. 
  3. Database Administration – As a database developer, you need to understand how to manage and maintain the health of the database. This means creating and setting up databases, monitoring and optimizing performance, ensuring data accuracy and integrity, implementing security measures and managing user access. 
  4. Data Modeling – Data modeling techniques involve creating a visualization of the data and its relationships within a database. It consists of defining how data is connected and how it will be stored and accessed. 
  5. ETL (Extract, Transform, Load) – ETL processes are fundamental in data warehousing and business intelligence. They involve extracting data from different sources, transforming it into a suitable format, and loading it into a database or data warehouse. This skill is important for ensuring data consistency, accuracy and readiness for analysis. 
  6. Backup and Recovery – Developers need to be skilled in creating strategies and implementing procedures for data backup and disaster recovery. This includes regular data backups, testing backups for reliability, and developing recovery plans to restore data in case of loss or corruption, ensuring business continuity. 
  7. Data Security – This skill involves understanding and implementing measures to protect data from unauthorized access, theft, and corruption. It includes developing security policies, conducting security assessments, and monitoring database activities to identify potential security risks.
  8. ERP and Business Knowledge – As a database developer, you need to understand how database systems support business processes and enterprise resource planning (ERP) systems. It involves comprehending business workflows, data integration, and how various business systems interact with the database, which is crucial for aligning database design with business objectives.
  9. Soft Skills – Besides technical skills, as you’ll also work collaboratively with teams, you need to have soft skills that include project management, problem-solving abilities, effective communication and attention to detail. 

Educational Pathways for Aspiring Database Developers

In most cases, to become a database developer, you start by having a Bachelor’s degree in computer science, software engineering or a related field. 

For a junior-level database role, a Bachelor’s degree may be enough. But for higher-level roles, you can consider taking a Master’s degree or getting specialized database developer certifications that include Computer Science, Data Science or Database Management. 

One minor note is that it’s not an obligation to have bachelor’s studies to become a database developer. There are many database developer training courses that have strong foundations and can help you land jobs. Let’s explore some of these:
