Study Notes
Introduction to Databases
- A database is an organised collection of logically related data; this provides the ability to interact with data and extract information and knowledge.
Data - Information - Knowledge - Wisdom
- Data is a collection of facts, numbers, audio clips, and images.
- Information is data with relevance and purpose.
- Knowledge is information placed in context based on facts and meanings, making it actionable.
- Wisdom is the understanding or necessary knowledge for effective decision-making, extracted from related data.
The Evolution of Databases - Manual Filing System
- Manual filing systems use an organised collection of documents in separate files.
- Files are logically related, and may be held in locked filing cabinets in different locations.
- Data can be manipulated, accessed, deleted, and updated.
- Data can be searched within the system, with first entry and indexing systems.
- This system works if there are a small number of entries, or a large number of entries, but it is used primarily for storage and retrieval.
