- 3Big DataDatasets that are too large and complex for businesses’ existing systems to handle utilizing their traditional capabilities to capture, store, manage, and analyze these datasets.
- 4ClassificationA data approach that attempts to assign each unit in a population into a few categories potentially to help with predictions.
- 5ClusteringA data approach that attempts to divide individuals (like customers) into groups (or clusters) in a useful or meaningful way.
- 6Co-Occurrence GroupingA data approach that attempts to discover associations between individuals based on transactions involving them.
- 7Data AnalyticsThe process of evaluating data with the purpose of drawing conclusions to address business questions. Indeed, effective Data Analytics provides a way to search through large structured and unstructured data to identify unknown patterns or relationships.
- 8Data DictionaryCentralized repository of descriptions for all of the data attributes of the dataset.
- 9Data ReductionA data approach that attempts to reduce the amount of information that needs to be considered to focus on the most critical items (e.g., highest cost, highest risk, largest impact, etc.).
- 10Link PredictionA data approach that attempts to predict a relationship between two data items.
- 11Predictor (or Independent or Explanatory) VariableA variable that predicts or explains another variable, typically called a predictor or independent variable.
- 12ProfilingA data approach that attempts to characterize the “typical” behavior of an individual, group, or population by generating summary statistics about the data (including mean, standard deviations, etc.).
- 13RegressionA data approach that attempts to estimate or predict, for each unit, the numerical value of some variable using some type of statistical model.
- 14Response (or Dependent) VariableA variable that responds to, or is dependent on, another.
- 15Similarity MatchingA data approach that attempts to identify similar individuals based on data known about them.
- 16Structured DataData that are organized and reside in a fixed field with a record or a file. Such data are generally contained in a relational database or spreadsheet and are readily searchable by search algorithms.
- 17Unstructured DataData that do not adhere to a predefined data model in a tabular format.
