Much of the world’s data resides in databases. SQL (or Structured Query Language) is a powerful language that is used for communicating with and extracting data from databases.
Working knowledge of databases and SQL is a must if you want to become a data scientist. No prior knowledge of databases, SQL, Python, or programming is required.
The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. It is also intended to get you started with performing SQL access in a data science environment.
The emphasis in this course is on hands-on and practical learning. As such, you will work with real databases, real data science tools, and real-world datasets. You will create a database instance in the cloud. Through a series of hands-on labs, you will practice building and running SQL queries.
A Database Management System (DBMS) is software designed to store, retrieve, define, and manage data in a database, it handles the storage, retrieval, and updating of data in a computer system. It serves as an interface between the end-user and the database and manages the data, database engine, and database to facilitate the organization and manipulation of data. A DBMS will define rules and manipulate the data format, field names, record structure, and file structure itself.
Database management systems differ in how information is internally organized. Internal organization affects how quickly and flexibly information can be obtained. Most databases contain multiple tables, which may each include several different fields. For example, a company database may include tables for products, employees, and financial records. Where databases are more complex they are often developed using formal design and modelling techniques.
The database management system (DBMS) is the software that interacts with end-users, applications, and the database itself to capture and analyze the data. The DBMS software additionally includes the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a “database system”. Often the term “database” is also used to refer to any of the DBMS, the database system or an application associated with the database.
