Study Notes

Relational Databases

  • Store and provide access to related data points
  • Based on the relational model, representing data in tables
  • Advantages:
    • Enforce data integrity through constraints like primary keys, foreign keys, and unique constraints
    • Allow for complex and flexible queries using SQL
    • Can handle large amounts of data and scale horizontally or vertically
    • Offer robust security features like user authentication, authorization, and encryption

Enterprise Resource Planning (ERP)

  • Integrate an organization's information into one overall system
  • ERP modules:
