- Information System
- Related: Management Information System, Data versus Information
An organised combination of people, hardware, software, data and procedures that collects, processes, stores and distributes information to support decision making, coordination and control in an organisation.
- Data versus Information
- Related: Information System, Information Quality
Data are raw, unorganised facts and figures with little meaning on their own; information is data that has been processed, filtered and contextualised so it becomes meaningful and useful to a decision maker.
- Information Quality
- Related: Data versus Information, Decision Making Levels
The degree to which information is accurate, timely, complete, relevant, concise and presented in a form the user can act upon. Poor quality information leads to poor decisions regardless of system sophistication.
- Management Information System
- Related: Information System, Decision Support System, Executive Information System
A computer-based system that converts internal transaction data into regular summary reports used by middle managers to monitor performance, compare actual results with plans and support structured decisions.
- Transaction Processing System
- Related: Batch Processing, Real-Time Processing
A system that captures and processes the routine, high-volume day-to-day transactions of an organisation, such as sales orders, payments and payroll, ensuring each transaction is recorded completely and accurately.

A tailored system for senior executives that presents high-level internal and external information through dashboards, trend indicators and drill-down facilities, emphasising ease of use over detailed transaction handling.
- Decision Making Levels
- Related: Management Information System, Information Quality
The classification of managerial work into strategic, tactical and operational levels, each needing different information characteristics: strategic needs summarised external and forward-looking data, operational needs detailed, frequent and internal data.
- Business Process
- Related: Business Process Reengineering, Value Chain
A set of logically related tasks performed to achieve a defined business outcome, such as order fulfilment or payroll, often crossing departmental boundaries and therefore a prime candidate for system support or redesign.
- Business Process Reengineering
- Related: Business Process, Change Management
The fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in cost, quality, speed and service, rather than incremental tweaking of existing procedures.
- Enterprise Resource Planning
- Related: Legacy System, Master Data, Business Process
Integrated software using a single shared database to support core processes such as finance, procurement, manufacturing, inventory and human resources, replacing disparate legacy systems with one consistent source of data.
- Legacy System
- Related: Enterprise Resource Planning, System Migration
An older application or platform still in productive use because it supports critical operations, often costly to maintain, poorly documented and difficult to integrate with newer technology.
- Systems Development Life Cycle
- Related: Feasibility Study, User Acceptance Testing, Waterfall Model
A structured project approach dividing system work into phases such as feasibility, requirements analysis, design, build, testing, implementation and review, each with defined deliverables and sign-off points.
- Feasibility Study
- Related: Systems Development Life Cycle, Cost-Benefit Analysis
An early assessment of whether a proposed system is technically achievable, economically justified, legally permissible and operationally acceptable, used to decide whether to commit further resources.
- Waterfall Model
- Related: Agile Development, Systems Development Life Cycle
A sequential development approach in which each phase is completed and approved before the next begins, offering clear control and documentation but limited flexibility when requirements change late.
- Agile Development
- Related: Waterfall Model, Prototyping
An iterative approach delivering working software in short increments with continuous user feedback, valuing adaptability to changing requirements over exhaustive up-front specification.
- Prototyping
- Related: Agile Development, User Acceptance Testing
Building a simplified working model of a system to clarify requirements and obtain user feedback early, after which the prototype may be refined, extended or discarded.
- User Acceptance Testing
- Related: Systems Development Life Cycle, Prototyping
Formal testing by intended users against agreed business scenarios to confirm the system performs required tasks correctly before it goes live and is accepted from the supplier.
- Changeover
- Related: System Migration, Change Management
The transition from an old system to a new one, carried out by direct, parallel, phased or pilot methods, each trading off risk, cost and disruption differently.
- Change Management
- Related: Changeover, Business Process Reengineering
The structured process of preparing people for, supporting them through and embedding organisational change, addressing communication, training, resistance and stakeholder engagement alongside technical delivery.
- Database
- Related: Relational Database, Database Management System, Primary Key
An organised collection of related data stored so that it can be accessed, managed and updated efficiently, usually under the control of a database management system.
- Database Management System
- Related: Database, Relational Database
Software that sits between users or applications and stored data, providing facilities for defining, storing, retrieving, updating, securing and backing up data, and controlling concurrent access.
- Relational Database
- Related: Primary Key, Foreign Key, Normalisation
A database in which data are held in tables of rows and columns and relationships are represented by shared key values rather than physical links, queried using structured query language.
- Primary Key
- Related: Foreign Key, Relational Database
A column or combination of columns whose value uniquely identifies each row in a table, must be unique and cannot be null, and is used to enforce entity integrity.
- Foreign Key
- Related: Primary Key, Referential Integrity
A column in one table whose values must match a primary key value in another table, used to create and enforce relationships and to maintain referential integrity between the tables.
- Referential Integrity
- Related: Foreign Key, Normalisation
A rule ensuring every foreign key value corresponds to an existing primary key value, preventing orphan records and keeping relationships between tables consistent when data are inserted, updated or deleted.
- Normalisation
- Related: Relational Database, Referential Integrity
The process of structuring tables to reduce redundant data and avoid insertion, update and deletion anomalies, typically by progressively ensuring each fact is stored once and depends only on the key.
- Structured Query Language
- Related: Relational Database, Database Management System
A standard declarative language for defining, manipulating and querying data in relational databases, including statements to select, insert, update, delete and control access.
- Data Warehouse
- Related: Data Mining, Dashboard, Master Data
A subject-oriented, integrated, time-variant store of data extracted from multiple operational systems, structured for querying and analysis rather than day-to-day transaction processing.
- Data Mining
- Related: Data Warehouse, Dashboard
The use of statistical and computational techniques to discover previously unknown patterns, correlations and trends in large data sets, supporting forecasting, segmentation and fraud detection.
- Master Data
- Related: Enterprise Resource Planning, Data Warehouse
The core, relatively stable reference data shared across systems and processes, such as customer, supplier, product and employee records, whose consistency is essential to reliable reporting.
- Dashboard
- Related: Executive Information System, Key Performance Indicator
A visual display consolidating key performance indicators, charts and alerts on a single screen so users can monitor status at a glance and drill into detail where needed.
- Key Performance Indicator
- Related: Dashboard, What-If Analysis
A quantifiable measure selected to track progress towards a critical business objective, defined with a clear formula, data source, target and reporting frequency.
- What-If Analysis
- Related: Decision Support System, Sensitivity Analysis
A modelling technique that changes one or more input assumptions to observe the effect on outcomes, allowing managers to compare alternative scenarios before committing to a decision.
- Sensitivity Analysis
- Related: What-If Analysis, Cost-Benefit Analysis
A technique that tests how much a result changes when a single input varies, identifying which assumptions most influence the outcome and therefore deserve closest monitoring.
- Cost-Benefit Analysis
- Related: Feasibility Study, Sensitivity Analysis
A structured comparison of the total expected costs of a project, including acquisition, implementation and running costs, against its expected tangible and intangible benefits, often using discounted cash flow.
- Batch Processing
- Related: Real-Time Processing, Transaction Processing System
A processing method in which transactions are accumulated over a period and processed together as a group, suited to high-volume routine work where immediate output is not required.
- Real-Time Processing
- Related: Batch Processing, Transaction Processing System
A processing method in which each transaction is handled immediately as it occurs, so that records and responses are current, essential where delay would cause error or loss.
- System Migration
- Related: Legacy System, Changeover
The planned transfer of data, functionality and users from an existing system to a replacement, requiring data cleansing, mapping, testing and rollback arrangements to control risk.
- Value Chain
- Related: Business Process, Business Process Reengineering
A model describing the sequence of primary and support activities through which an organisation creates value for customers, used to identify where information systems can add competitive advantage.
