Tables
A table is a rectangular array of elements, where each element represents a specific value. It is commonly used to organize and display data in a structured format.
Key features of tables:
Rows and Columns: A table is typically organized into rows and columns. Each row represents a different record, and each column represents a specific attribute or field of that record.
Elements: Each cell in the table contains a single piece of data.
Data types: Tables can contain different data types, such as numbers, strings, and dates.
Relationship to arrays: A table can be considered an array of elements, where each row in the table represents an element in the array.
Purpose: Tables are used for various purposes, including:
Data storage: They allow us to store and access data in a structured format.
Data analysis: They can be used to analyze data by grouping and summarizing information.
Data communication: They can be used to communicate data between different systems.
Examples:
A table of students' information, such as name, age, address, and marks, could be used to store and access student data.
A table of sales data could be used to analyze trends and identify patterns.
