Introduction to Database Management Systems (DBMS)

DBMS is a system for storing, managing, and retrieving data.
Data and Information are different: Data is raw facts, while Information is processed data with context.
Examples of data include names, quantities, dollar amounts, and characteristics of students and courses (Name, Age, Level, Gender, Title, Cost, Hours, Type).
Examples of information include lists of students, male students, and the number of optional courses.

Types of Data

Raw data comes in various formats: numbers, strings, text files, audio, and video.
Structured data is organized in a predefined format, like spreadsheets (rows and columns).
Semi-structured data has some organizational structure, but not as rigorous as fully structured data, like a spreadsheet with partially missing data.
Unstructured data lacks a predefined format and is challenging to store and manage; examples include text documents and images.

How to Store Data

Databases offer structured ways to store information.
Relational databases store data in related tables, making data retrieval efficient.
Structured data is easily stored in databases, but some data may be unstructured and difficult to organize.

Case Study

A database is needed to store student information, including courses, grades, and instructors.
A suitable solution needs to be designed to manage this data.
