Databases & Data Storage
Table
Definition
In a relational database, a table is a collection of related data held in a structured format within a database. It consists of columns and rows.
Why It Matters
Tables are the fundamental organizational structure in a relational database. They provide a simple and intuitive way to represent and store structured data.
Contextual Example
A `Users` table in a database would have columns like `UserID`, `FirstName`, `LastName`, and `Email`. Each row in the table would represent a single, unique user.
Common Misunderstandings
- A table is analogous to a spreadsheet, but with much stricter rules about the data types allowed in each column.
- The structure of a table, including its columns and their data types, is called its "schema".
