Core Aspects of Computer Technology and Its Components Flashcards
What is Software?
a collection of computer programs and related data that provides the instructions for telling a computer what to do and how to do it.
What is Hardware?
Term for equipment that can be touched by hand.
For computer system, it is the one that make up how the computer will look like and it is what we are actually using.
State 3 Types of Software
System Software
Application Software
Programming Software
Peopleware

computer software and hardware systems.
Give examples of peopleware
Computer engineers, software engineers, information technology specialists, website designer, computer technicians
Dataware
Data Warehouse/Enterprise Data Warehouse
Central repository of data which is created by integrating data from multiple disparate sources.
Data Warehouse Architecture: Bottom Tier
consists of a data warehouse
server, usually a relational database system, which
collects, cleanses, and transforms data from multiple data sources through a process known as Extract, Transform, and Load (ETL) or a process known as Extract, Load, and
Transform (ELT).
Data Warehouse Architecture: Middle Tier
consists of an OLAP (i.e. online analytical processing) server which enables fast query speeds. Three types of OLAP models can be used in this tier, which are known as ROLAP, MOLAP and HOLAP. The type of OLAP model used is dependent on the type of database system that exists
Data Warehouse Architecture: Top Tier
end user interface or reporting tool, which enables end users to conduct ad-hoc data analysis on their business data
