Data Science
The process of uncovering patterns and trends in large datasets to support predictions and decisions.
Data Mining
A multidimensional visualisation tool used in spreadsheets to summarise and explore data.
Pivot Table
A computer program designed to mimic human problem-solving using “if–then” rules.
Expert System
Testing a system’s ability to handle large amounts of data to ensure performance, reliability, and accuracy under heavy data loads.
Volume Testing
Visual representations of how data moves through a system, showing inputs, processes, outputs, and data stores.
Data flow diagrams
A function that searches for a value in the leftmost column and returns a value in the same row from a specified column.
VLOOKUP
A statistical measure showing how strongly two variables are related
Correlation
Unique biological measurements or behavioral patterns that can be used to identify individuals
Biometrics
A visual representation of project tasks against time, often used to track progress.
Gantt Chart
Diagrams that show the sequence of processes, data flows, and decisions in a system using standardised symbols.
System flowcharts
The process of cleaning and transforming raw data into a usable format, removing errors, and resolving inconsistencies.
Data Wrangling
A visual interface that displays key metrics, trends, and data summaries in real time to support enterprise decision-making.
Dashboard
Computer-based system that can reason, learn, and act autonomously to achieve goals by adapting to changing environments and inputs.
Intelligent System
Creating a tangible, early version of a product or service to test and refine ideas before final development.
Prototyping
Graphical models that represent decisions by classifying or predicting outcomes through breaking down complex decisions into a series of simpler "if this, then that" rules.
Decision trees
A technique that reduces a large dataset into smaller, meaningful subsets by grouping rows based on common attributes.
Data Aggregation
A diagram used to display frequency distributions where values are grouped into ranges.
Histogram
Assists users in making informed decisions by analysing data, generating insights, and presenting actionable options.
Decision support systems
The process of checking that an enterprise system meets user requirements and performs its intended purpose correctly.
Validation
A visual sequence of sketches or images that outlines the order and flow of a system/narrative, used to plan structure and interactions before implementation.
Storyboard
High-speed, multi-dimensional analysis of large volumes of data to support business intelligence and decision-making
OLAP
A misrepresentation of data caused by distorted axes, misleading scales, or excluded context.
Data Visualisation Bias
Statistical method that models the relationship between a dependent variable and one or more independent variables by fitting a straight line to the data.
Linear Regression
The process of identifying potential problems in an enterprise project, assessing their likelihood and impact, and planning strategies to reduce or manage them.
Risk Analysis
Structured blueprint that defines how data is organized in a database, including tables, feilds and their relationships.
