Relational databases - 🧠ANSWER ✔✔A database in which data is divided
into tables, which are kind of like spreadsheets. Each table has just one
subject, such as customers (one table) or products (another table).
Records and fields - 🧠ANSWER ✔✔Storage for the discrete data in a table.
Rows (or records) store each unique data point, such as the name of a
customer. Columns (or fields) isolate the information being captured about
each data point into the smallest possible unit—first name might be one
column and last name might be another.
Primary key - 🧠ANSWER ✔✔A value that ensures each record is unique.
For example, there might be two customers with the same name, Elizabeth
Andersen. But one of the Elizabeth Andersen records has the number 12
as its primary key and the other has a primary key of 58.
