A crow's feet diagram, commonly used in the field of data modeling, is a type of entity-relationship diagram (ERD) that visually represents the relational structure of database systems. It employs a specific notation—resembling crow's feet, hence the name—to indicate the cardinality of relationships between entities, such as one-to-one, one-to-many, or many-to-many. This diagrammatic approach helps database designers and engineers conceptualize, communicate, and document database schemas, allowing for a clearer understanding of how data entities relate to one another, which is crucial for the efficient planning, implementation, and maintenance of database systems.

The objective highlights the indispensable role of databases in supporting the infrastructure of modern daily life, from online transactions and search engines to course catalogs, emphasizing our reliance on them for various aspects of daily living. It underscores the importance of proper design, implementation, and management of databases, especially in the context of the expanding Internet of Things and the growth of online transactions, pointing out that these areas offer numerous employment opportunities. The project discussed aims to guide readers through the processes involved in the design, development, and implementation of a relational database, underlining the critical nature of databases in our increasingly digital world.
Therefore my objective was to "Design a database system using ER diagrams and normalization. Create the database in a Relational Database Management System using SQL and create queries to retrieve data from the database."
