![]() SQL developers should have strong programming fundamentals, including experience with one or more programming languages such as Java.NET, C++, Python, or Ruby on Rails. They may also develop processes to import data from external sources and migrate databases when moving to new technology, such as onto cloud database systems. They are usually responsible for cataloging and organizing data into tables, specifying data types, primary and foreign keys, and other constraints. Database design and managementīefore writing programs, SQL developers must design a database. You can also add filters, charts, and other visualizations on top of this data–which means you’ll need to learn how to write queries to use them effectively. Pivot tables extract and arrange data into neat categories and subcategories for quick analysis. If you’re working with data in Excel and want to summarize it using pivot tables, you’ll need to know how to write SQL code. ![]() 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. SQL developers often help connect databases with business intelligence software packages, like Power BI and Tableau. Integrating databases with business intelligence softwareīusiness intelligence software is the umbrella term for applications that help companies analyze data. 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. SSAS (SQL Server Analysis Services): Microsoft's tool for building OLAP cubes, which are useful for business intelligence applications SSRS (SQL Server Reporting Services): Microsoft's reporting tool for SQL Server databases, which is useful for creating reports SSIS (SQL Server Integration Services): Microsoft's tool for ETL processes, which is loading data from one database to another Job advertisements frequently list SSIS, SSRS, or SSAS SQL Server experience as essential criteria for application. SQL Server is particularly popular in corporate environments. Microsoft also offers Azure SQL Database as a cloud-based service. Like MySQL, SQL Server has a variety of versions, each supporting different features and scales of data. Microsoft SQL Server is a popular relational database management system developed by Microsoft Inc., which runs on Windows servers. 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. It runs on multiple platforms-including Windows and Linux- and can support small and large databases. Michael Widenius, who cofounded MySQL AB, (which is now part of Oracle), with David Axmark in 1995, developed MySQL. MySQL is currently the most popular open-source database management system. These include MySQL, Microsoft SQL Server, and PostgreSQL. Database managementīesides knowing the language, SQL developers need to be familiar with one of the major database management systems. SQL is the programming language used to interface with databases. The first, and most apparent SQL developer competency, is proficiency in SQL (Structured Query Language). These skills are necessary to thrive in an SQL developer role. SQL developers must possess a combination of workplace and technical skills. 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. Code can also be complex, involving multiple tables linked via a web of interconnected relationships, such in supply chain enterprise resource planning (ERP). 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. They may design database architecture, write complex queries for applications and business intelligence reporting, or create dashboards. CRUD is an acronym for create, read, update, delete and refers to the four operations developers perform on database tables to manipulate the data.Īs an SQL developer, you'll optimize database performance, create complex functions and stored procedures, analyze queries, develop security protocols, and resolve problems. SQL developers use structured query language (SQL) to create and modify database tables using CRUD SQL commands. The role of an SQL developer is to develop and manage SQL databases by planning, developing, and maintaining the databases.
