Introduction to SQL and Database Systems
Here, we will introduce SQL (Structured Query Language) and the concept of database systems. If you’re interested in pursuing a career in data management, consider undergoing comprehensive Data Science Training to gain a deeper understanding of SQL and its applications.
SQL is a powerful language used for managing and manipulating relational databases. It allows users to create, modify, and retrieve data from databases. Database systems are software applications that enable the storage and retrieval of data in a structured manner.
Relational Database Management System (RDBMS)
What is an RDBMS?
RDBMS is a type of database management system that organizes data into tables with predefined relationships between them.
Key Features of RDBMS
RDBMS offers several essential features, including data integrity, ACID properties (Atomicity, Consistency, Isolation, Durability), and support for complex queries.
Examples of Popular RDBMS
Some of the well-known RDBMS systems include MySQL, PostgreSQL, Oracle Database, and SQL Server.
NoSQL Databases: Breaking the Relational Boundaries
In this section, we will explore the concept of NoSQL databases and how they differ from traditional SQL databases. For those interested in advanced data management techniques, consider exploring the Best Data Science Course offerings to expand your knowledge.
