What is SQL (Structured Query Language)?

SQL can be defined as a standardized language used by database administrators when managing relational databases or performing different operations on the data in those databases.

It was created over four decades ago and has grown in popularity over the years. It is also used by developers when writing scripts for data integration and data analysts for running analytical queries.

Taking an SQL Training Course

Every developer wants to be conversant with SQL. Fortunately, you can easily gain access to a course today. For instance, those based in London can learn and master SQL to confidently manipulate and query data by taking SQL certification courses.

Taking such courses allows you to perform different operations on data, among them;

• Deleting, updating, and adding rows of data.
• Modifying database indexes and table structures.
• Getting information subsets from database systems. You can use this information for things like transactional processing and analytics among others.

Why is SQL Still So Important?

Simplicity

SQL is one of the easiest programming languages we have today. Within a few days, a beginner can learn the basic functions that they need to return data and run queries.

If you look at some non-technical roles such as product management, marketing, and some executive roles, you will realize that they need a basic understanding of SQL.

Understanding SQL deeply might take a significant amount of time. However, any person can learn the basics easily and within a short time frame.

Thoroughly Tested

SQL has been around for over four decades, meaning that it has been used in different types of applications. It has played a central role in global applications as well as pre-web offline applications.

SQL has, therefore, gone through vigorous tests over the years. It has also become the better option when it comes to database management. SQL has remained unshaken even after running for many hours in production. 

Developers want a database management system that helps them avoid common database security vulnerabilities. This is important especially when running applications where failure can be catastrophic. SQL has proven itself.

Community and Knowledge

When something remains relevant for a long time, people and communities tend to gain a lot of knowledge about it. This applies to SQL.

The past four decades have seen increased development of SQL knowledge in different forms such as thriving communities and documentation.

This knowledge and active community will make SQL remain relevant for a long time. This is because, with the extensive documentation and active communities, developers and companies are going to keep gravitating towards SQL.

Interoperability and Open-Source

SQL is not completely interoperable. This is because vendors such as MS SQL Server and Oracle (News - Alert) use a different syntax. They do not follow the same standards.

Fortunately, the SQL syntax is the most popular and slightly varies from that of the other vendors. This means that you can modify SQL and use it with other database management systems.

However, you need to be careful when doing this. It is not an ideal situation and you should follow the best practices when writing your SQL queries.

In addition, SQL is open-source. You do not have to subscribe to any paid options or struggle when looking for documentation. This makes it highly accessible.

Ubiquity

Almost every other developer either uses SQL or has used it at some point in their development life. This makes the technology ubiquitous.

Some people might argue that this is a bad thing. However, with the communities and knowledge bases discussed above, as well as its simplicity, SQL has become common knowledge.

This has ensured that SQL skills are easily transferred from one industry or company to another, ensuring that there is readily available talent. In turn, this fuels community growth and knowledge creation.

In conclusion, SQL has remained relevant for over four decades. With the number of applications it is running today, we are going to see it around for even a longer time. It is, therefore, important to take SQL certification courses to grow with it.
