Data warehouse-

• an information system that contains historical and commutative data from one or more sources
• this is a relatively new science that involves studying, planning, and developing interactions between people (users) and computers
• it is a system software that manages computer hardware, software resources, and provides general services for computer programs
• The interface depends mainly on the number and variety of inputs and outputs, which are communication channels that allow users to interact with the computer through this interface.
• visual basis for computer interaction

A field -

• this is a piece of record with a single Data Fragment.
• this is a database optimized or designed for a virtualized environment
• this is a set of instructions and rules that will help you use the DBMS
• this is a systematic data set
• this is a relatively new science that involves studying, planning, and developing interactions between people (users) and computers

Database specification

• The data in the database is shared by different users and applications.
• Easier for a beginner to learn/use
• Not very good for novice users
• It can be much faster than typing on the keyboard
• Everything is correct

Database specification

• Data is organized and interconnected
• Very convenient (effective) when there is a limited number of options)
• Not very good for novice users
• It can be much faster than typing on the keyboard
• Everything is correct

Database specification

• Data is protected from unauthorized access.
• The user interface may be limited by screen space and the number of options available.
• Easier for a beginner to learn/use
• Very convenient (effective) when there is a limited number of options)
• No need to learn complex commands/language

Database specification

• The reliability and integrity of the data is also ensured in the database.

Advantages of the database

• improved data security
• Time is consumed in designing complex database systems
• Damage to database affects virtually all applications programs
• Considerable hardware and software start-up costs
• Extensive conversion costs in shifting from a file-based system to a database system
