A way to visualise a network
What is a network diagram?
This term describes software that can make decisions without human intervention
What is an intelligent system?
Nominal, Ordinal, Interval & Ratio Level
What are the four Levels of Measurement?
This type of approach involves users trialling a system, giving feedback, and then modifying the system based on that feedback
What is prototyping?
A line added to data to show direction over time
What is a trend line?
A graph representative of data flows between external entities and the system, without any form of database.
What is a level 0 DFD?
This subset of intelligent systems enables computers to “learn” patterns from data without being explicitly programmed
What is machine learning?
Large complex datasets that traditional processing software can't manage effectively
What is big data?
Hiring workers outside your home country to complete tasks at a lower cost while accessing more skills is known as this
What is offshore development (outsourcing)?
This occurs when results favour one group over another due to poor sampling
What is data bias (sampling bias)?
Shows project tasks as horizontal bars across a timeline. Used for scheduling, dependencies, and tracking project progress
What is a gantt chart?
Expert systems often use these structured rules to make decisions
What are if–then rules?
An advanced database that allows transparent information sharing, stores data in chronological blocks and prevents unauthorised transaction entries.
What is blockchain?
Tools such as system flowcharts, data flow diagrams, and decision trees are used in this stage to organise and plan a system
What is researching and planning?
This export format is lossless and good for high-quality images
What is PNG?
Diagram that maps decisions and possible outcomes using branches and nodes. Commonly used in predictive modelling and DSS.
What is a decision tree?
Machine learning systems require this type of data to improve performance
What is training data?
Data Swamps
This method of introducing a new system gradually, step by step, allows an organisation to transition without halting operations
What is phased implementation?
This limitation makes spreadsheets unsuitable for large-scale enterprise visualisation projects
What is poor scalability and limited customisation?
Visualises entities, attributes, and relationships in a database system. Used for designing structured databases and data warehouses
What is a Entity Relationship Diagram?
This field of AI focuses on enabling systems to interpret and understand human language
What is natural language processing (NLP)?
A backup that saves additions and alterations since the last full backup
What is a differential backup?
This type of testing checks whether the final system meets the client’s requirements and is ready for deployment
What is acceptance testing?
Unlike spreadsheets and static presentations, this type of tool allows real-time integration and decision-making support
What are business analytical services?
