This document discusses information systems and data gathering. It covers direct and indirect sources of data, how data is coded for storage and analysis, benefits and drawbacks of coding, and how the quality of the original data source impacts the quality of the resulting information through the concept of "garbage in, garbage out".
The document discusses data flow diagrams (DFDs) which are used during systems analysis to show how data moves through a system. A DFD diagrams processes, data stores, external entities and data flows. It provides examples of symbols used in DFDs including processes, data flows, data stores and sources/sinks. The document also discusses constructing DFDs at different levels, with level 1 diagrams showing more detail than the initial context level 0 diagram.

This document summarizes key UK legislation constraining the use of customer data and information technology, including the Data Protection Act of 1984/1998, Computer Misuse Act of 1990, and regulations around health and safety. It outlines principles of fair and lawful processing of personal data, requirements for data controllers to register and comply with subject access rights, and exemptions for certain data types and uses. Offenses related to hacking, viruses, copyright infringement and unauthorized access or modification of data and systems are also defined.
BTEC National in ICT: Unit 3 - MIS Features and Functionsmrcox
?
An information system has four main functions: input, storage, processing, and output. There is often a feedback loop so the system output can affect future input. An information system takes in detailed data through input, stores and processes it, and produces output information. The output can then provide feedback to users to influence future inputs into the system and analyses requested. Key elements that make up an information system include data, people, hardware, software, and telecommunications infrastructure.
BTEC National in ICT: Unit 3 - Operational Issuesmrcox

BTEC National in ICT: Unit 3 - Data Flow Diagrams Introductionmrcox
?
This document provides an overview of data flow diagrams (DFDs) and structured analysis. It defines DFDs as tools that model how information flows through a system and is processed. The document outlines the basic symbols used in DFDs, including external entities, data flows, data stores, and processes. It also explains how to draw context diagrams at the highest level and then refine them to more detailed lower levels through decomposition. The goal of DFDs is to hierarchically break down a system into independent, understandable components.
BTEC National in ICT: Unit 3 - Ethical Issuesmrcox
?
Many organizations have codes of practice that define acceptable uses of computing facilities, with the main use being to support the organization's purpose. These codes often permit limited personal use and ban threatening emails or spam. They also restrict access to inappropriate websites and control web server content, while protecting employees who report other users' misuse. Organizational policies state how information is treated, such as restricting access to authorized personnel only, and data ownership lies with the departments that produce it, not the IT department that sets up systems.
