1. System Software and Application Software
Application software
User-oriented computer programs that deal with user related
problems or tasks. Such as MS Word, MS Excel, ERP software,
mobile apps.
System software
• Operating system
Communicates with the hardware system, responsible for
resource allocation (allocation of the available memory or
computing time). Such as MS Windows, Mac OS X,
Windows Mobile, Android, iOS
• Other system software (Support software)
Helps develop, maintain or provide non-application-
specific performance. Such as editors, compilers, virus
scanners, firewalls, database management software.
2. Enterprise Application System
Application Systems
Definition: In the broader sense, the totality of all programs for a specific business
application or specialist area. This includes the application software and the
associated data.
What belongs to an enterprise application system?
Hardware: computer systems for end users as well as for central processing and
data organization,
input and output devices.
Software: operating systems, database systems, enterprise application software
Data and Databases: master data, modification data, stock data, and transaction
data
Networks: wired and wireless networks, routers, firewalls and other communication
systems such as VPN, DNS
Security Measures: Measures to protect data, systems, and users from security
threats.
3. Enterprise Application System Fields of Use
- Finance and accounting
