- [Narrator] Now that we have a…pretty comprehensive list of data elements…that we need to store, it's time to…start organizing them into the…structures that we'll need to go in the database.…By doing so, we're going to start building…what's called a data model.…A data model is a graphical representation…of the elements that make up…the overall database's design.…It's the construction blueprint…that we've been working towards.…The data model will also help us…visualize the tables, fields, and…the relationships that will allow the database…to both store and retrieve information very efficiently.…Tables represent the various types of…entities that we want to keep track of in the database.…
And records or rows in those tables…hold information about a single person,…place, thing, or event.…In order to discover the tables that we need to create.…We need to take a close look at the…field list that we generated in the last chapter…and start organizing them into…logical groupings of entities or subjects.…As you start to scan through the fields…
Adam Wilbert covers the basics of relational database design, regardless of whether you use Access, FileMaker, Open Office, or SQL Server. Learn how to prevent data anomalies, gather requirements to plan your design, and develop a conceptual data model—translating your ideas into components like tables, relationships, queries, and views. Plus, learn about logical design considerations that can help you construct a database that is easy to maintain.
