Business Intelligence Concepts

Flashcards based on lecture notes about business intelligence concepts, focusing on data hierarchy, data warehousing, OLAP types, exploration methods, and data processing techniques.

Business Intelligence

The process of analyzing data to help make informed business decisions.

Concept of Hierarchy

A structured representation showing the relationships between different concepts within a company.

Data Warehouse Design

The process of structuring data storage for effective retrieval and analysis.

Data Mart

OLAP

Online Analytical Processing, a computing method that allows for the analysis of data stored in data warehouses.

ROLAP

MOLAP

Multidimensional Online Analytical Processing, a type of OLAP that uses multidimensional data cubes.

HOLAP

Hybrid Online Analytical Processing, which combines ROLAP and MOLAP for improved performance.

Hypothesis Driven Exploration

An approach to data exploration where the user has a specific hypothesis that guides their analysis.

Discovery Driven Exploration

An exploratory approach that relies on data exceptions to guide the discovery of insights.

Data Processing

The collection and transformation of data to produce meaningful information.

Clustering

The process of grouping a set of objects in such a way that objects in the same group are more similar to each other than to those in other groups.

Data Cleaning

The process of identifying and correcting inaccuracies or inconsistencies in data.

Data Generalization

A process that abstracts detailed data into generalized forms for higher-level analysis.

Attribute-Oriented Induction

A method of data mining where generalization takes place based on analysis of attributes.

Aggregation

The process of summarizing data by grouping and computing metrics.
