Along with the roadmap, please continue reading the article below. We also delve into the concept, job description, and requirements.
A SQL developer (also known as SQL programmer) is an expert in information technology.
Their primary duties are designing, creating, and maintaining websites or information systems using the SQL structured query language.
This language is quite popular in data systems thanks to its function of cleaning, retrieving, and organizing the information it stores. You can find them on websites, organizational packages, or apps.
SQL developers must also know various structural query languages such as PostgreSQL, Oracle, SQL Server, SQLite, and MySQL.
These professionals have meticulous attention to detail and strong logical thinking. As a result, they will easily solve difficult information problems at work.
They also need a background in programming. Sometimes, these experts even have to teach SQL coding to colleagues.
SQL developers build, develop, and manage enterprise data systems based on SQL.
Their working time in a week is 40 hours and working hours are the same as office hours. This job can both work at the office and allows working from home.
Some of the key tasks these professionals need to take on daily include:
The first responsibility of SQL programmers is to write SELECT queries of varying degrees of complexity.
Most of the commands you put out will be extremely simple. However, some unexpected situations still arise, and you need to deal with them.
Sometimes, experts will have to race against time and try to write a workable SELECT query. After each work, you will accumulate more practical experience.
These queries are extremely important because their outputs influence the organization’s business decisions.
Depending on the location and size of the business you’re working for, you’ll likely spend some time programming stored functions, procedures, and triggers.
The reason is that this information is stored in the form of a database. During execution, you also need to use a combination of SQL statements such as INSERT, SELECT, DELETE, and UPDATE.
In addition, database specialists occasionally change and update organizational information systems.
This action can include creating relationships and inserting or deleting tables.
After learning about the functions and daily work of a SQL developer, it’s time to learn about the roadmap of this career.
Careers related to information technology often give preference to candidates with a bachelor’s degree. SQL development is no exception.
You should earn a degree related to information systems or computer science.
These training programs will provide you with computer networking and programming knowledge.
In addition, they also support you with the basics of database management. It is one of the top recruitment criteria.
Some classes that you should focus on as much as possible include:
- Calculus and Algebra.
- Algorithm design.
- Computer Algorithms.
- Computer organization.

Once you have the basics, you need to apply them to solve real-world problems. These experiences will help your resume stand out in the job market.
You can find internship opportunities through your university, as some majors offer those options.
Also, try to research the organizations you want to work for to understand the recruitment requirements. You’ll be more likely to get hired when you develop the right skills for the organization.
Because you will be spending most of your time working with databases, it is helpful to have additional knowledge in this area.
You don’t have to go to college, but you can save time by enrolling in online courses or short-term boot camps. Some notable topics include:

With tech-related careers, you must accumulate as much practical experience as possible.
Start with a simple personal project based on a topic that interests you, like movies or music. Then create, query, and design the information associated with them.
If possible, reach out to friends and family to help them with small projects. As a result, you will have more knowledge to beautify your portfolio and impress the business.
Having professional experience will help you enjoy higher benefits and salaries. You should also hone your knowledge of Java, C, or C# to communicate with other departments.

- Microsoft Certified Professional Developer (MCPD)
- Data Management and Analytics from Microsoft Certified Systems Engineer.
- Oracle PL/SQL Developer Certified Associate.
You will need to pass the training center exams to receive the certificate.
One helpful tip is to focus on digging into one specific area. Having only a basic understanding of many information environments will limit your opportunities.
Besides professional knowledge, SQL programmers also need to equip soft skills to work more effectively.
You will not work alone. There will be many departments working together to establish digital transformation within an organization.
Multiple departments will need each other’s information to complete the information system. People will be able to ask for your help or ask related questions.

In addition, you should also learn how to write notes and reports in a way that is easy to understand and concise.
To become successful in this field, you will need to focus on acquiring the following skills:
Information systems can be used as a layered architecture layer. Its effect is to develop services by separating interfaces and business logic.
So, it makes the information processing process much simpler and cleaner.
Many professionals use this information to design physical and logical relational database models.
As a SQL programmer, you will definitely need to know this language. It allows you to access and control information systems.
By using table variables and temporary tables, experts can create complex queries. As a result, they can design and deliver dynamic reporting solutions using hosted services.
Another name for this platform is Transact-SQL. It extends the SQL query language with more utilities and executable statements.
By using complex commands, experts can filter information from legacy systems.
Microsoft created Microsoft SSIS as an ETL tool. Thanks to this tool, you can integrate, store information into a single source, and perform cleaning.
These applications allow professionals to deploy and develop business solutions for various organization departments.
Professionals need to have excellent analytical skills to listen to and analyze customer needs. As a result, they can design the software according to their needs.
