SQL developer job responsibilities

The role of an SQL developer is to develop and manage SQL databases by planning, developing, and maintaining the databases. SQL developers use structured query language (SQL) to create and modify database tables using CRUD SQL commands. CRUD is an acronym for create, read, update, delete and refers to the four operations developers perform on database tables to manipulate the data. 

As an SQL developer, you'll optimize database performance, create complex functions and stored procedures, analyze queries, develop security protocols, and resolve problems. They may design database architecture, write complex queries for applications and business intelligence reporting, or create dashboards.

Some queries and application functionality can be simple, such as a command to pull up all records related to a specific customer in an e-commerce database. Code can also be complex, involving multiple tables linked via a web of interconnected relationships, such in supply chain enterprise resource planning (ERP).

SQL developers’ code allows users to interact with the information stored in databases, access metrics that show key business insights and provide decision support to the organization.

Proficiency in SQL

The first, and most apparent SQL developer competency, is proficiency in SQL (Structured Query Language). SQL is the programming language used to interface with databases.

Database management

Besides knowing the language, SQL developers need to be familiar with one of the major database management systems. These include MySQL, Microsoft SQL Server, and PostgreSQL.

MySQL

MySQL is currently the most popular open-source database management system. Michael Widenius, who cofounded MySQL AB, (which is now part of Oracle), with David Axmark in 1995, developed MySQL. It runs on multiple platforms—including Windows and Linux— and can support small and large databases.

PostgreSQL

PostgreSQL is another open-source relational database management system available on all major platforms (and some minor ones) and is supported in various cloud computing environments.

Microsoft SQL Server

Microsoft SQL Server is a popular relational database management system developed by Microsoft Inc., which runs on Windows servers. Like MySQL, SQL Server has a variety of versions, each supporting different features and scales of data. Microsoft also offers Azure SQL Database as a cloud-based service. 

SQL Server is particularly popular in corporate environments. Job advertisements frequently list SSIS, SSRS, or SSAS SQL Server experience as essential criteria for application.

You don’t need to be an expert in all these areas before becoming an SQL developer, but it helps to have a good grasp of at least a few of these tools and resources.

Integrating databases with business intelligence software

Business intelligence software is the umbrella term for applications that help companies analyze data. SQL developers often help connect databases with business intelligence software packages, like Power BI and Tableau.

It might be an SQL developer’s responsibility to modify the database schema to ensure that external applications can access data or even to build a new database from scratch to meet the needs of a business case.


What Can SQL do?

Notes:

We use sql to make software according to your needs.

For example, people in the medical field are creating better ways to communicate things. Not only medical, we do it in all fields.
