What is SQL?
SQL (Structured Query Language) is the most common programming language used in database management systems across the globe. We offer beginning to advanced SQL training to meet a variety of database management needs. Whether your goals are to understand the essentials of the SQL language and querying data or to create and maintain your own highly efficient database, we have a course and an expert instructor to meet your needs. SQL students learn how to turn complex data sets into actionable insights using techniques including writing queries to sort and filter data, using math functions and logic statements to target specific data, using data conversion functions to maximize report readability, and incorporating advanced functions to establish and maintain efficient database management procedures.
Why Learn SQL
SQL is the most common programming language for interacting with databases, and as more companies move to the cloud, SQL skills are becoming more critical. SQL skills are beneficial for both developers and business analysts as developers are often tasked with building or connect databases and analysts are often tasked with analyzing data from databases. From the business analyst side, SQL can increase your marketability and get you ready for a variety of jobs, and it is relatively easy to learn. SQL, as compared to Python, is easy to learn, and with a couple of short lessons, you'll be able to do most data analysis projects required of you.
Topics in SQL
Starting off in SQL, you'll want to build a foundational understanding of what relational databases are and how they work. This knowledge underscores the importance of SQL to interact with relational databases. Then you'll move into actually interacting with databases by writing SQL queries. For example, in just one line of SQL "code", you can extract all rows in a table that meet certain criteria.
Once you have the basics down you'll learn to work with grouping and mathematical functions, as well as joins which allow you to connect multiple tables on a join key. After a couple of days of training, you'll be a SQL pro and you'll see just how powerful a couple of lines of SQL code can be to perform common data analysis tasks.
