- 1dataunprocessed, unorganised and distinct facts or ideas.
- 2Informationprocessed, organised and value- added data. It can be paper-based (hard copy) or digital (soft copy).
- 3solutiona method for solving a problem. In information technology, the problem- solving methodology is a way of developing solutions.
- 4Relevant datathe desired purpose. To identify relevant data, you need to be able to assess the usability of the data and determine the characteristics of the targeted audience.
- 5Usable datathe properties of suitability, reliability, accuracy, timeliness and freedom from bias.
- 6Characteristics of audiencesare gender, special needs, culture, age, education level, status and location.
- 7data typea set of data with predefined characteristics. The most common data types are integer, floating point numbers, character and string.
- 8graphic representationpictorial diagram that shows the interdependencies between variables. Common types derived from numerical data are column charts, line charts, pie graphs, bar charts, area charts, scatter diagrams and bubble charts.
- 9Layout diagramsdetail the content of a
solution. They are a visual sketch of a graphic representation, and contain detailed descriptions of each element of the content. - 10spreadsheetmade up of worksheets (rows and columns).
- 11Spreadsheet formulasinclude conditional, lookup, date and time, financial, statistical, math, counting, conversion and text.
- 12Spreadsheet functionsinclude the ability to format data, sort and filter data, and perform mathematical, logical, financial, statistical and scientific functions and create charts and graphs.
- 13Design elementsare factors that influence
the appearance and effectiveness of graphic representations. These elements include proportion, orientation, clarity and consistency, colour and contrast, usability and accessibility, appropriateness and relevance. - 14Efficiencyis measured in terms of time, cost and effort. Spreadsheets include functions that enable a user to work quickly and
with less effort in order to produce graphic representations, thereby minimising cost. - 15Effectivenessrelates to how well a solution meets the specified need and fulfils the specified purpose. It is measured in terms of completeness, readability, attractiveness, clarity, accuracy, accessibility, timeliness, communication of message, relevance and reliability.
- 16Validationchecks that data input to a computer system is appropriate and reasonable.
- 17Manual validations performed by a person, not a computer, and includes proofreading and checking for illegal data types, for reasonableness, for correct spelling, to ensure that data falls within a correct ‘range’, or that any codes used are consistent and reasonable.
- 18Electronic validationis performed by a computer and includes range checking, existence checking, data-type checking and restricted data entry.
20 Validation alerts communicate to the user that the data entered does not adhere to the validation rules set. - 19formata way of presenting data, such as centring text or adding dollar signs to represent currency.
- 20conventionan accepted and standard way of formatting data.
- 21Testingperformed to ensure that the processes, functions and formulas of a solution operate and manipulate data as expected. A solution needs to be tested for its effectiveness.
