Study Notes
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.
