Want to become a database development or database management system (DBMS) wizard? Learn about what a database developer does and the skills needed to reach the level of DBMS wizard.
What Does a Database Developer Do on a Day-to-Day Basis?
Database developers work in the IT department and are responsible for the development and maintenance of databases. The database developer will often analyze current database procedures in order to develop solutions to streamline inefficient coding. This involves monitoring, troubleshooting, and debugging databases to solve performance issues.
The tasks of DBMS wizard include:
- Developing database solutions that meet business requirements
- Documenting work of operational responsibilities
- Supporting database services in the design, delivery, and operation of database solutions
Many database developers use SQL to create databases. SQL enables applications to access the data in a database management system (DBMS).

Structured Query Language is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). SQL is used to communicate with a database.
According to ANSI (American National Standards Institute), it is the standard language for relational database management systems. SQL statements are used to perform tasks such as update data on a database or retrieve data from a database. Some common relational database management systems (DBMS) that use SQL are Oracle, Sybase, Microsoft SQL Server, and Access.

A database management system (DBMS) is software that controls the storage, organization, and retrieval of data. Typically, a DBMS has the following elements:
Kernel Code – the code that manages memory and storage for the DBMS.
Repository of Metadata – a read-only collection of database tables and views containing reference information about the database, its structures, and its users.
Query Language – SQL enables applications to access the data.
What Does a SQL Database Developer Do on a Day-to-Day Basis?
SQL database developers are responsible for the development, modification, and organization of databases. SQL database developers provide guidance in design, implementation, and maintenance of data systems. SQL database developers are in charge of implementing and controlling security procedures to protect data from damage, loss, or theft. The SQL database developer needs to be able to troubleshoot problems and come up with solutions.
The tasks of a SQL database developer include:
- Testing and documenting software
- Analyzing requirements and transforming them into technical designs
- Writing, modifying, and debugging software
- Designing and developing application components
What Are the Skills Needed to Reach DBMS Wizard Status?
Analytical Skills – A database developer must be able to monitor a database system’s performance to determine when action is needed. The database developer must be able to evaluate complex information that comes from a variety of sources.
Communication Skills – Most database administrators work on teams and must be able to communicate effectively with developers, managers, and other workers.
Detail Oriented – Working with databases requires an understanding of complex systems in which a minor error can cause major problems.
Logical Thinking – Database developers must make sense of data and organize it in a meaningful pattern so that it is easily retrievable.
Problem Solving Skills – When problems with a database arise, developers must be able to troubleshoot and correct problems.
