Sequential Codes: These are numeric or alphanumeric codes assigned in a specific sequence, often used for tracking and organization.
Example: Invoice numbers in a billing system (001, 002, 003).
Advantage: Easy to generate, simple to understand, and efficient for chronological organization.
Block Codes: Codes grouped into specific ranges or categories for better organization.
Example: 100-199 for electronics, 200-299 for furniture, etc.
Advantage: Simplifies data categorization and makes retrieval easier.
Both systems improve data management, with sequential codes focusing on order and block codes on classification.
