# TABLES
|
|
|
|
A database, often referred to as a schema in a relational context, is an organized collection of structured data. It's the persistence layer for your application, essential for storing and managing information that outlasts application processes.
|
|
|
|
Think of it as a reliable system ensuring data validity and enforcing relationships without requiring excessive application-level checks.
|
|
|
|
## Tables and Columns
|
|
|
|
The fundamental unit of a database is the table. Tables organize data into rows and columns, similar in concept to a spreadsheet but with enforced structure and data types.
|
|
|
|
Each column within a table holds a specific type of data (e.g., text, numbers, dates), defining the structure for every entry.
|
|
|
|
Consider a simple task management application. Key information would reside in distinct tables:
|
|
|
|
* **Users:** Stores user-specific data. Columns might include `username`, `name`, and `active` status.
|
|
* **Tasks:** Contains task details. Relevant columns could be `task_name`, `status`, `due_date`, and `priority`.
|
|
|
|
The `Users` table structure illustrates this:
|
|
|
|
| id | username | name | active |
|

## Table Structure Summary
|
|
|
|
* The table is defined by four columns: `id`, `username`, `name`, and `active`.
|
|
* Each row represents a distinct record, with three entries (users) shown here.
|
|
* The `id` column serves as the unique identifier for each record, typically configured for automatic incrementing.
