can you make ER Diagram with Crow`s foot method about library system. The rule: 1. A member can borrow more than one book at a time 2. A member can have more than one phone number 3. A book can have more than one author 4. All book registration, member and borrowing processes can only be done/served by officers 5. Data for books, members and officers are stored with a unique id, so no id is the same.
Concepts in Designing Database
A database design is the process of data organization based on a database model. The process deals with identifying what data should be stored in a database and how data elements relate to each other.
Entity Relationship Diagram
Complex real-world applications call for large volumes of data. Therefore, it is necessary to build a great database to store data safely and coherently. The ER data model aids in the process of database design. It helps outline the structure of an organization’s database by understanding the real-world interactions of objects related to the data. For example, if a school is tasked to store student information, then analyzing the correlation between the students, subjects, and teachers would help identify how the data needs to be stored.
