Name three key elements of an expert system and describe their purpose. (~50 words)
Knowledge Acquisition: Process of obtaining expert knowledge from human experts, documents
etc.
Knowledge Base: Contains the expert knowledge in a codified format, e.g., in the form of
inference rules.
Inference Engine: Logical framework that is used to execute a line of reasoning. Uses user input
and inference rules as input and provides a result (diagnosis, recommendation etc.) as output.
Can be viewed as the "brain" of the expert system.
Explanation Subsystem: Explains the reasoning that the system used to arrive at a decision, for
example, it may list the rules that were followed.
User Interface: Modules that the user interacts with. It is typically very user-friendly, thus
appropriate to use for a non-expert user.
Name two representative uses of an expert system:
Diagnose problem situations and prescribe treatments:
Diagnose and prescribe medical treatment for diseases
Diagnose mechanical problems with diesel engines (or computers, printers, airplanes, or cars...)
Locate faults in telephone cables
Help with oil drilling (detect when a drill bit gets stuck)
1|Page
,Fraud detection:
Help to detect signs of insider trading on the stock exchange and decide to open an
investigation
Help to detect accounting fraud and decide to perform an audit
Analyze proposed bank loans
Scheduling:
Help determine the optimal sequence of stops on a truck route.
Help determine manufacturing scheduling
Advice:
Help with setting and pursuing career goals
Help with managing pension benefits
Help with irrigation and fertilization decisions in agribusiness (e.g., peanut farming)
Help dealing with OSHA-regulations (e.g., asbestos situations)
Help with managing benefits for welfare recipients
Describe two important reasons to implement an enterprise resource planning (ERP) system.
(~50 words)
Data and application integration: ERP systems provide a common database that is used by a
(large) number of applications all throughout the enterprise. The main focus of the ERP-
applications is on transactions.
Business process reengineering/standardization: ERP systems typically include standard
business processes that reflect common industry practice. This can mean the need to change
business processes in parts or all of an organization.
Process automation: ERP systems may eliminate the need for manual processes that have relied
on paper in the past and instead provide an automated process bases on electronic forms.

List three important characteristics of an Enterprise Resource Planning (ERP) system (~25 words)
-Supports transaction processing
-Central database that can be used by many applications (integrated data)
-Supports multiple functional areas
-Complex system; expensive; implementation projects are lengthy and come with many risks
2|Page
, -Frequently require changes in business processes (industry standards) and/or customization of
the software
-Originated in manufacturing and production scheduling; today usually includes modules for
accounting, HR; newer installations also cover supply chain management and customer
relationship management
In extracting information from large data warehouses, a data mining tool may use which of the
following techniques?
decision trees
regression
rule induction
all of these*
What is a characteristic of a system with batch processing?
processing costs are typically lower than for online/real-time processin
Which of the following is the least typical characteristic of a modern executive information
system?
requires the user to have a solid technology background
A large vendor of ERP systems headquartered in Germany is called [blank].
SAP
Explain two benefits/goals of the Hadoop-approach to Big Data Management and Data
Warehousing. (~25 words)
Allows to include structured as well as all sorts of unstructured data from various sources, on
premises/inhouse and cloud-based.
Horizonally scalable and affordable because it's based on commodity hardware
Allows for massive parallel processing
Based on open source software components
Which of the following approaches to representing spatial data relies on dividing space into
small, equal-sized cells arranged in a grid?
raster-based GIS
