Types of Systems

Types of Systems

– Transaction processing systems (TPS) process data for routine business functions – sales, payroll, inventory, etc.

– Office automation systems (OAS) manage or organize information

• Includes MS Office applications, desktop publishing, scheduling, voice or email, video conferencing

Types of Systems

– Knowledge work systems (KWS) are used by various professionals to help them create new knowledge and share it with their organization or profession

– Management information systems (MIS) take input from TPS and helps analyze that data to make better decisions• Typically uses models of business processes or rules

– Decision support systems (DSS) are more customized systems to help make good decisions

Types of Systems

– Artificial intelligence (AI) refers to a set of techniques for creating complex systems, whether they perform mundane tasks or expert tasks• AI also includes natural language processing (NLP),

neural networks, and other approaches

– Knowledge-based systems (KBS) are AI systems that represent knowledge explicitly• Expert systems are the first KBS methodology;

they go beyond DSS to create new rules or select from existing rules to make their own decisions

• KBS may use statistical approaches to deal with uncertainty, or apply fuzzy set theory

Types of Systems

– Computer-supported collaborative work (CSCW) is a relatively new field to help groups of people work together on a project, whether in the same room or on different continents

• Group decision support systems (GDSS) is a subset of CSCW used to focus on group decision-making

– Executive support systems (ESS) help top management levels evaluate the overall status of an organization, often drawing from many TPS or MIS

Technologies

• All of these types of systems can be supported by various kinds of technology

– E-commerce has had a profound influence on the way businesses reach clients

• Nothing else has had global impact on marketing at such small cost

– Web-based systems are becoming universal

• From four computers in 1969, the Internet protocols have provided a common language for almost every computer, and many devices

Technologies

– Enterprise resource planning (ERP) systems are designed to integrate what were separate systems (manufacturing, payroll, logistics, etc.)

• SAP is a big local player

• Oracle just bought PeopleSoft

• JD Edwards is also in the field

– Wireless networks are common now

• Wireless LANs (WLANs), Bluetooth, or generic Wi-Fi (802.11g)

Technologies

– Smart Phone are increasingly common too

• Android, IOS, Win Phone, Blackberry, Palm, etc.

– Open source software has emerged in the last decade from a geek oddity to a significant force in the market

• GNU and Linux are big players

Technologies

Business Analyst

• A Business Analyst is someone who analyzes an organization or business domain (real or hypothetical) and documents its business or processes or systems, assessing the business model or its integration with technology.

There are at least four tiers of business analyst:• Strategic planning — to identify the organization's business

needs• Business model analysis — to define the organization's

policies and market approaches• Process design — to standardize the organization’s

workflows• Systems analysis — the interpretation of business rules and

requirements for technical systems (generally within IT)
