AND PROBLEM IDENTIFICATIONClaryfingthe Research Question through Data and Exploration Dr. Myrza Rahmanita, SE, M.Sc
[ ]
The five types of external information and the factors for evaluating the value of a source and
its content.
The process of using exploratory research to understand the management dilemma and work through the stages of analysis necessary to formulate the research question (and, ultimately, investigative questions and measurement questions)
What is involved in internal data mining and how internal data-mining techniques differ from literature searches.

Data collection (1960s) “What was my average total revenue over the last five years?”
Computers, tapes, disks Retrospective, static data delivery
Data access (1980s) “What were unit sales in California last December?”
Relational databases (RDBMS), structured query language (SQL), ODBC
Retrospective, dynamic data delivery at record level
Data navigation (1990s) “What were unit sales in California last December? Drill down to Sacramento.”
Online analytic processing (OLAP), multidimensional databases, data warehouses
Retrospective, dynamic data delivery at multiple levels
Data mining (2000) “What’s likely to happen to Sacramento unit sales next month? Why?”
Advanced algorithms, multiprocessor computers, massive databases
Prospective, proactive information delivery
