When going through some of the popular job boards online, you could easily see SQL Developer is one of the most demanding jobs sought by companies. As we all know today, companies collect vast volumes of data and store it in their own databases. They want professionals with a good understanding of data who can keep it safe and secure.
Who is a SQL Developer?
So first, we will understand who is a SQL Developer?
A SQL Developer is a person who is accountable in creating and managing huge data sets of a company. In other terms, SQL Developer is a person who can develop SQL databases as well as write and test code.
Let's understand this with the help of an example. Let's say we want to search for a particular product on the Amazon website. And Amazon has stored all its data about products in a database. Now we will write the product name in the search bar. And when we click on the search button, it will run a SQL query that fetches all the information about the product and displays us on the website. So this is the basic task done by a SQL Developer.
Responsibility of a SQL Developer
Now, we will understand the responsibilities are for SQL Developer. All Databases have a structure and logic behind how data is stored and retrieved.
Well, SQL Developer designs the database accordingly. For businesses that is called database modeling. After the database is created and deployed, it's the SQL developer who is responsible for fixing the general issues of the database.
SQL Developer should be well versed with Structured Query Language to create optimised SQL queries, and refine the existing ones to extract information from the database.
SQL developers run several diagnostic tests to keep a check on the server and the database. In order to understand how to organize company's data.
SQL developers must communicate with technical and non technical persons from the business and SQL Developer also gathers client requirements and identifies the features that the database owner responds to.
As data is an asset to a company SQL developers Backup and Restore data for the client. They also perform tasks like data management and data migration. That is, if a company has stored all its data on a local storage, and now it puts its data to be stored in a cloud storage. So the safe transmission of the data from local storage to cloud storage is known as data migration. And that is done by the SQL developers.
After knowing the responsibilities now, I should look for the skill set required to be a good SQL Developer.
Once you have a good knowledge of SQL commands, functions, joins and procedures.
Let's have a look at a few commands such as create, drop, alter, and truncate, these commands come under data Definition Language. We also have insert, update and delete commands. These commands come under data manipulation language, we have grant and revoke commands. These commands come under data control language, we also have commit rollback and savepoint commands. These come under transaction control language.
These are the basic commands a SQL Developer should be familiar with.
And a SQL Developer may have a little command on any one programming language. You don't have to be experts in programming. All you need is how to interface between the application and your database.
For example, if you are using MySQL and your web application is based on PHP, then you should know how to connect your application to the database and how to issue queries, how to fetch results, and then how to display it to the users.
One should have a good understanding of various database management systems such as
- MySQL,
- Microsoft Access,
- Oracle,
- Postgresql database,
- FoxPro,
- sequel lite,
- IBM DB to LibreOffice Base,
- Maria DB and
- Microsoft SQL Server.
One should know integration of databases with data visualization software such as Power BI And W, which has businesses to make better decisions and give you an add on as a SQL Developer, one should develop critical thinking and problem solving skills to create optimised queries.
Now we'll see how SQL Developer is compensated in both the United States and India.
In the United States, SQL developers grow an average salary of dollar 72,282 per annum.
In India, the average salary of a SQL Developer is four lakh rupees 49,532.
Now we'll see how a person can become a good SQL Developer. for that.
One should have a good command on Structured Query Language and know how to interact with database management systems and can issue queries to get the desired result.
Earning industry recognized SQL Developer certifications such as Microsoft Certified Professional developer, mcpd, or Oracle PL SQL Developer Certified Associate, which usually require a passing score on an exam, and it's important to accumulate as much practical experience as possible. Start by designing, creating and querying small databases connected with your hobbies and interests.
For example, your favorite music videos or your personal finances. This will enable you to gain experience, test your knowledge and build your project portfolio, which will be highly beneficial when you start applying for the first full time position.
Now we will see some major companies deactivating SQL developers. First we have the multinational Financial Services Corporation, American Express, followed by the multinational professional services network, Ernst and Young. We also have the messaging company WhatsApp. Then we have the e-commerce giant Amazon, as well as the technology and computer solutions company Dell.
Finally, in our list of companies, we have the multinational technology company Google.
With that we have come to the end of this session. I hope it was exciting and informative. If you liked it, please let us know in the comment section below.
