What Can You Do with SQL Skills?
Because SQL is all about accessing data from relational databases, SQL skills will allow you to do just that, as well as handle large amounts of data, perform data analyses, and store back-end data. Here are some of the more common uses for SQL and what skills you’ll need to know to join the workforce.
Data Science and Analytics
Data science and analytics rely on SQL. In data analytics, Data Analysts visualize the data and interpret the visualizations to help facilitate data-driven decision-making. In data science, Data Scientists organize data and develop machine learning algorithms to build predictive models, focusing on building, cleaning, and organizing large datasets. SQL plays a major role in both data science and data analytics, allowing data professionals to access data and prepare it to be manipulated. Without SQL, there is no clear path forward to accessing, maintaining, organizing, and manipulating the data stored in relational databases.
Database Management
Database management covers the way data is stored, organized, and maintained in a database. The goal of database management is to keep data secure and easily accessible to those who need it. With SQL, Database Managers can communicate with a database to create and modify tables, update records, and retrieve information. SQL is a key component of database management and makes it possible to work with large datasets to make the work of Data Scientists, Data Analysts, and other data professionals easier.
Web Development
Web development is concerned with all of the technological processes that go into building and maintaining a website. One of the many web development tools is SQL. Web development is often divided into three areas: front-end, back-end, and full-stack. SQL is a tool for back-end development and full-stack development. Both Back-End Developers and Front-End Developers use SQL to manage the server side of websites and web applications to ensure that everything runs properly.
Software Engineering
Society is relying more heavily on computer-driven processes than ever before. Software engineering is what powers the processes and creates the programs and applications users have come to depend on. Software Engineers use programming languages like SQL and others to develop software and web applications. Software engineering is behind the development of applications like Spotify, Netflix, and Pandora, all of which use SQL to access databases and provide the content users expect to experience.
How to Decide Which SQL Class is Right for You
One of the hardest parts of learning SQL is choosing the right class for you. With SQL being one of the simplest languages to learn, you can expect a class dedicated solely to SQL to be less than one week long, but there will be courses that include SQL that can span several weeks to a couple of months. Beyond scheduling, you’ll also want to consider a few other key factors when making your choice, including the course’s content, the learning format, your budget, and course reviews. A little research in these categories will make your choice easier, whether you’re completely new to SQL or have had some experience, allowing you to manage your expectations and prepare yourself for learning SQL.
Course Content
Consider what it is you want to learn and compare it to the course’s learning objectives. While there are several versions of SQL, like NoSQL and MySQL, you don’t want to end up in one of these courses when you’re looking for basic SQL or vice versa. Think about why you’re learning SQL and how you want to apply your knowledge. Are you looking to increase your tech skills? Are you looking to break into a new profession? Answering these types of questions can help you decide whether or not a course’s content is going to help you achieve your learning objectives and get you where you’re trying to go. Reviewing the course description and syllabus is the best way to understand how useful a particular SQL course will be to you. You’ll also want to notice whether or not it is a beginner-friendly course or one that has prerequisites.
Live Online vs. On-Demand
There are several learning formats, and live online and on-demand are two of the main options. There are advantages and disadvantages to each that you will need to consider. Both options allow you to take an SQL course wherever you are, but on-demand classes do not have a schedule. They allow you to learn at your own pace and schedule, starting, stopping, pausing, and rewinding as you need. These courses are best suited to those who have hectic or irregular schedules. Live online learning, alternatively, requires that students meet at the same time from their respective locations. Live online SQL classes are great for those who can’t commute to class, but still want to have more of a traditional learning experience that comes with in-person classes.
Live online classes allow you to interact with the instructor and your classmates in real-time, while many on-demand courses do not have this ability. Some on-demand courses will schedule live Q-and-A sessions or have live discussion boards for learners. Live online classes also offer real-time feedback, an invaluable quality that can help avoid extreme frustration and provide support with challenging concepts or reassurance. When taking an on-demand class, you’ll have to wait for feedback, which may slow you down to some degree. On-demand classes also tend to be more cost-efficient than live online courses.
Budget and Schedule
The cost of an SQL class is perhaps the deciding factor for many students. Having a budget in mind helps you narrow down your choices so you can make a more thorough comparison and choose the best class for you. Because SQL is such an easy programming language to learn and the classes tend to be short, the price tag isn’t usually too steep. But if you want to enroll in a certificate program or bootcamp that covers SQL and other data-related topics, you should expect a significantly higher price tag.
Scheduling, like cost, can make or break an SQL class. There are several scheduling options available, and each will suit different needs. A part-time schedule is great for students who have busy lives, are working professionals, and those who prefer to learn at a slower pace. Full-time scheduling can be a little intense because it packs a lot of information into a short span. If you can take off the time it takes to complete a full-time program and you’re eager to get into the workforce, this may be the better option for you. You’ll also find SQL classes that run during evenings or on the weekends.
Reviews
Don’t underestimate the power of reviews. While positive reviews are great, it is often helpful to also critically read negative reviews. Consider whether or not the complaints are due to facility or student error, how their issue was resolved or went unnoticed, and how the facility responded to the negative review. Don’t just look for reviews on the training center’s website. No center wants to showcase negative opinions of their business. Spend a little time combing the Internet to learn what reviews didn’t make it onto the training center’s site. This can help you see a more objective picture of what it is like to attend a class there. You’ll get a good sense of what the instructors and staff are like and how well students are supported in reaching their goals.
