question
What are the different processes that are used to analyze patterns, trends, and relationships in data mining?
answer
The different types of processes that are used to analyze patterns, trends, and relationships are the goal seeking analysis, market basket analysis, text mining, forecasting, optimization, and what-if analysis. The market basket analysis looks for relationships to reveal customer behavior patterns as they purchase multiple items. Text mining on the other hand, is a variation of data mining, and refers to a discovery process in which unstructured text information is the source of business intelligence, rather than structured data. A what-if analysis builds a model that establishes relationships between many variables and then changes some of the variables to see how the others are affected. Goal seeking analysis is similar to what-if analysis, but in reverse. It is a process which allows the user to set a target value for a particular metric and tell the program which variable to change to try to reach the goal. Forecasting tools analyze historical and seasonal trends and then take into account existing and predicted business conditions to estimate some variable of interest, such as customer demand or projected revenue.

answer

question
Discuss how expert systems function and the challenges faced by developers in building it.
answer
An expert system mimics the reasoning of a human expert, drawing from a base of knowledge about a particular subject area to come to a decision or recommendation. To build an expert system, developers work with experienced and specialized professionals as they provide answers to questions and explain their reasoning processes. The output is fine-tuned continually as the experts contribute more knowledge to the base, refine the rules, and add additional questions. The process is challenging, often because experts don't quite know exactly how they reach their conclusions. Formally identifying the actual steps is harder than it appears, but the results can be quite dramatic and enormously useful for decision support.

question
What is an online analytical processing system and how does it work?
answer
Online analytical processing systems allow users to interactively retrieve meaningful information from data, examining it from many different perspectives and drilling down into specific groupings. The software allows users to "slice and dice" massive amounts of data stored in data warehouses to reveal significant patterns and trends. OLAP systems help spot suspicious activity as well. Medicare anti-fraud strike forces, for example, use such systems to detect unusual billing that might point to illegal scams. OLAP systems achieve their speed and their slice-and-dice capabilities by building multidimensional cubes. These are data structures that contain detailed data, and also aggregated values for the dimensions, metrics, and hierarchies the users need.

question
Discuss how dashboards, portals, and mashups support the decision making process.
answer
The IT dashboard is a graphical user interface that organizes and summarizes information vital to the user's role and the decisions that the user makes. Portals are gateways that provide access to a variety of relevant information from many different sources on one screen. They are content aggregators, making it easier for users to view and drill down into company dashboards, weather announcements, news, traffic reports, stock reports, to-do lists, e-mail, and discussion groups. A newer approach to aggregating content from multiple internal and external sources on customizable web pages is the mashup. This approach relies on Web 2.0 technologies and programming standards such as XML to blend content and updated feeds from various inside and outside sources in flexible ways.
question
________ refers to the ratio of visitors who complete an activity on a site divided by the total number of visitors.

question
What is forecasting and how does it work?
answer
Forecasting tools usually analyze historical and seasonal trends and then take into account existing and predicted business conditions to estimate some variable of interest, such as customer demand or projected revenue. Forecasting tomorrow's demand, next month's sales, or next year's stock price relies especially on statistical decision support tools. For example, forecasting will depict the relationship between the summer season and an increase in the sale revenue of ice cream.

question
What are the major differences between the key levels of decision making?
answer
Operational-level decision making requires detailed structured information about actual transactions by customers, so staff can follow up and track each transaction. However, at the tactical level, decision makers need more aggregated information, sorted and tallied in different ways, to monitor success and plan next steps. The business intelligence that executives need to make better decisions is often less structured in strategic levels than at the operational or even management level. Top-level executives certainly need summary and historical data from the company's own transactional systems and data warehouses. But they also need competitive business intelligence about their rivals, broader information about the industry landscape, and a forecast of overall economic and business conditions.

What is artificial intelligence and how is it an integral part of the decision support system?
answer
Artificial intelligence (AI) describes the capability of some machines that can mimic human intelligence, displaying characteristics such as learning, reasoning, judging, and drawing conclusions from incomplete information. For business, AI makes valuable contributions in areas such as financial monitoring and customer relationship management. AI is also valuable for fast-moving emergency situations when the volume of incoming data could overwhelm human decision makers. The human and robot together learn from one another, just as a human baby and parent learn from and adapt to each other's moods.

question
What are the three key types of decision making levels?
answer
Business intelligence supports three different types of decision making levels. These are primarily decisions made at the operational level, tactical level, and strategic level. Operational-level decisions involve routine transactions and direct interaction with customers. These decisions may involve unprogrammed decision making, but generally consist of programmed decisions. On the other hand, tactical-level decisions draw upon business intelligence to make mid-level decisions, the kind that may guide individual business units. Decisions about marketing plans, product development, membership drives, departmental budgets, and other initiatives are generally tactical. Decisions made at the strategic level have widespread effects throughout the organization and beyond, to suppliers, customers, and even the whole industry. Each decision could commit huge amounts of capital and people to major initiatives.
