Database definitions
1. Field: In database systems, fields are the smallest units of information you can access.
Record: Records are composed of fields, each of which contains one item of information.
File: Almost all information stored in a computer. Must be in a file. There are different types of files: data files, text files, program files, directory files and so on.
Query: In the method, the system presents a blank record and lets you specify the fields and values that define the query.
Database: Traditional databases are organised by field, records and files.
Report: A formatted and organized presentation of data.
DBMS: A collection of programs that enables you to store, modify, and extract information from a database(Database Management system).
Data dictionary: a file that defines the basic organization of a database.
Data type: we can usually do this through -, %, : and $. This indicates the datatypes.

They are all in categories e.g most recently played. The most important one we use everyday, GOOGLEEE.
