Why obtain an SQL certification?
The answer lies in the tangible value it adds to your professional profile. An SQL certification not only validates your technical knowledge but also demonstrates your commitment to continually developing your skills. A certification can set you apart from other candidates, and it can also offer a significant advantage during salary negotiations.
What are the different SQL certifications available?
There are various SQL certifications available, depending on your research and skill level. Here are the main recognized certifications:

Choosing the right SQL certification
It can be challenging to determine which one best suits your needs and career aspirations. To make an informed choice, it’s important to consider several key factors, such as your career goals, current skill level, and available resources.
Career goals
Identify the field you wish to evolve in. For example, if you aim for a career in data science, a certification like “SQL for Data Science” might be more relevant. In contrast, if you aspire to become a database administrator, a certification specific to MySQL or PostgreSQL would be more appropriate.
Some certifications are more recognized than others in specific sectors. Naturally, Oracle certifications are highly valued in companies using Oracle databases, while Microsoft certifications are better suited to Azure environments.
Skill level
Ensure you choose a certification that matches your current skill level (not all certifications require the same level of expertise).
Also, check the prerequisites for each certification. Some may require prior experience or specific knowledge, which could influence your choice.
