What is a database structure?

Understanding Database Structure

Definition:

• Foundation of Data Organization: The framework or arrangement that dictates how data is stored, managed, and accessed within a database system.
• Hierarchical Arrangement: Establishes the layout, organization, and relationships among different data elements.

Components of Database Structure:

1. Tables:

   • Fundamental Elements: Where data is stored in rows and columns.
   • Represent Entities: Each table typically represents an entity (e.g., customer, product) or a relationship between entities.

2. Columns (Attributes):

   • Data Fields: Represent specific types of information within a table.
   • Characteristics: Define the type of data each column holds (e.g., name, age, date).

3. Rows (Records/Tuples):

   • Individual Entries: Contain specific instances of data.
   • Collection of Values: Corresponding to attributes/columns.

4. Keys:

   • Unique Identifiers: Ensure distinctiveness within the database.
   • Primary Key: Uniquely identifies each row in a table.
   • Foreign Key: Establishes relationships between tables.

Importance of Database Structure:

• Data Integrity: Ensures accuracy, consistency, and reliability of stored information.
• Efficient Data Retrieval: Facilitates quick and precise retrieval of relevant data.
• Optimized Performance: Structuring data properly contributes to faster query processing and system performance.
