Data modeling and Databases

• A database should be designed to store all data relevant to the business and provide quick access and easy modification.
• When building a database you must consider the following
1. content: what data should be collected and at what cost?
2. access: what data should be provided to which users and when?
3. logical structure: how should data be arranged so it makes sense to the given user
4. physical organization: where should data be physically located?
