SQL : Solve real-world data problems with SQL Queries Course Description
SQL stands for Structured Query Language. SQL lets you access and manipulate databases.
SQL became a standard of the American National Standards Institute (ANSI) in 1986 and became a standard of the International Organization for Standardization (ISO) in 1987. In addition to the SQL standard, most SQL database programs have their own proprietary extensions! ! . SQL is a standard language used to store, manipulate, and retrieve data in a database. The world of computer technology is changing very fast, and databases are no exception.
The latest data-related buzzwords are data lakes, data science, Internet of Things (IOT), data disputes, machine learning, etc. It’s no longer big data, cloud data, ETL, data analysis, dashboards, business intelligence, etc. But… what basic skills do you need to use these new database technologies? SQL! Almost everything related to data requires SQL.
Database systems have existed since the 1970s and are widely used in all businesses and organizations. And to use these databases at a less basic level, you need to understand and write SQL. And unlike other technologies and programming languages (which change very frequently), SQL is more stable. Once you learn it, this is a skill you can use for life. To truly absorb and apply your learning, you must solve real-world problems. Presenting and solving SQL problems will help you understand and remember concepts and principles, which is unique.
Learning how to analyze data problems, break them down into basic knowledge, and come up with elegant and readable SQL solutions requires practice and experience. In most cases, this level of practice and experience only comes from working with large data sets in the real world for many years. However, through the well-designed set of questions in this course, you can develop skills comparable to those years of experience. And these skills will help you get the job you want.
SQL practice questions will teach you how to “think” in SQL, how to analyze data problems, how to discover basic principles, and how to work for solutions you are proud of. It contains challenging questions that can hone your ability to write high-quality SQL code. Through SQL Practice Problems, you can gain experience in solving some of the most common challenges in data, as well as the best and most useful techniques to solve these problems. You are faced with data analysis and report-oriented challenges designed to help you.
Through introductory, intermediate and advanced SQL Select statements, and “learning by doing” techniques. The problem is business oriented and uses an order database. Solve problems and absorb the techniques introduced-this will provide you with the skills and experience needed to solve real data problems.
