What is information systems as a frame?Show answer
An information system is the people, data, processes and technology that work together to perform information processes. Across the course every system is described using the same five components: participants (people who carry out the processes), data and information, information processes, and information technology (the hardware and software). The seven information processes are the verbs that describe what the system actually does.
What is collecting?Show answer
Collecting is gathering data and entering it into the system. It covers deciding what data is needed, identifying the source, and capturing it. Capture methods include manual keying, barcode scanning, optical mark recognition, sensors and web forms. Good collection considers the accuracy and relevance of the data and avoids collecting more than is needed.
What is organising?Show answer
Organising arranges collected data into a form suitable for the other processes. This includes structuring data into records and fields, formatting it, coding it (for example storing a state as a short code), and sorting it. Organisation is what turns a messy pile of raw input into something a database or program can work with.
What is analysing?Show answer
Analysing interprets organised data to find meaning, patterns or relationships. It includes selecting relevant data, comparing it, and drawing conclusions. Querying a database, building a model, or running a what-if scenario in a spreadsheet are all analysis. Analysis is where raw data becomes useful information.
What is processing?Show answer
Processing manipulates data to create new data or to update what is stored. It includes calculations, editing, updating records, and transforming data from one form to another. When a payroll system multiplies hours by a pay rate, or a transaction system deducts stock, that is processing.
What is displaying?Show answer
Displaying presents information to people in a form they can understand and use. It includes screen output, printed reports, graphs, audio and video. Good display considers the audience and the purpose, choosing the format (table, chart, dashboard) that communicates most clearly.
