Data
The terms ‘data’ and ‘information’ are often used interchangeably but they do not mean the same thing.
The term ‘data’ refers to unprocessed facts or statistics that have no context.
Information

It is data that has been given context (meaning).

- Identify Potential Sources
- Source and Select Information
- Select the most appropriate tools
- Process and analyze data
- Record and store information
- Share results
Data Analysis Tools
- Data Tables (Databases are often split into tables to be easier to update, view and manipulate)
- Visualisation of Data(Visualising data (by producing a chart or graph of collected data for example) makes it easier for an audience to see trends and patterns.)
- Trend & Pattern Identification
- Data Cleaning (removing unnecessary data)
- GIS / Location Mapping (Using geographic data to any analysis. Location of staff to see production flow etc.)
Types of information systems
Open Systems
Closed Systems
Open information system
This type of system can interact with other information systems (e.g. another database) to exchange data, even from different platforms (types of computers).
Disadvantages: it is more at risk of data loss and/or hacking as it communicates with other systems.
Closed Information Systems
This type of system is private and cannot exchange data with other systems.
Access is limited but it is much more secure than an open system.
Management information systems
