Data is literally everything that you read, watch or down/upload online. That means your emails, pictures, files, videos, music and Video Games. Anything that has a unit of measurement next to it (Kb, Mb, MB, Gb, GB, etc) is data, and will affect you in or way or another.
Data consists of raw facts and figures. When these raw facts and figures are processed by a computer, they become information.

1) Database is designed and built with data for a specific purpose. 2) We can perform the operations simply on database. 3) Database provides a logical relational b/w its record and data.
Computers work with a binary number system that consists of only two digits - zero and one. Inside the computer binary number is represented by an electrical pulse. One means a pulse of electricity and zero means no pulse. All the data entered into computers is first converted into the binary number system. One digit in binary number system is called bit and combination of eight bits is called byte. A byte is the basic unit that is used to represent the alphabetic, numeric and alphanumeric data. Data is represented inside a computer as a series of on and off pulses. Humans think of those pulses in terms of a binary-based numbering system. Data is the combination of characters, numbers and symbols collected for a specific purpose. Data is divided into three types; alphabetic data, numeric data and alphanumeric data. Numeric data consist of ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, two signs + and - and decimal point . There are different types of number system that are used to represent numeric data. These number systems are decimal number system, binary number system, octal number system and hexadecimal number system. Alphabetic data is used to represent 26 alphabetic. It consist of capital letters from A to Z, small letters from a to z and blank space. Alphabetic data is also called nonnumerical data. Alphanumeric data used to represent alphabetic data, numeric data, special character and symbols.
Radar systems usually use wavelengths and are associated with digital signal processing. They consist of a transmitter, antenna receiver, switch, data recorder, processor, and display. Radar systems are used to track things including weather.

It is qualitative data.
Relational database stores data in tables that consist of rows and columns. Each row represents a record and each column represents a field within that record. Relationships between tables are established through keys.
In general it is called alphanumeric.

A data warehouse architecture is similar to various relational database systems. What makes the best architecture is the organization of the warehouse itself and the data it consist of.
No. A table is the primary object used within a database to store data. A typical database will consist of many tables.
A unit of data size that consist of 8 bits is a byte (or octet in European countries).
