Data Type Report for ICT320 Database Programming Task 2, 2017

This document presents a data type report for a database programming task, likely related to the creation of a database for a car rental company ('CurRENT CarRENTals'). It outlines the data types (e.g., INT, VARCHAR, CHAR, DECIMAL, ENUM, DATE, TIMESTAMP) and descriptions for various fields within several tables, including Customer, Accessory, Insurance, Penalty, VehicleType, FuelType, Discount, PayType, Vehicle, Rental, RentAccessory, RentalCharge and Sale. The report specifies the purpose and constraints of each field, such as maximum lengths for integers and variable-length strings, fixed lengths for characters, and precision for decimal values. The report also includes references to resources on functional dependency and relational database design, indicating an understanding of database normalization principles. The information is well-organized and provides a clear overview of the database schema and data type considerations.
