Data sources
Data Sources

  • A data source is the place where data comes from originally

  • Direct data is data that has been gathered for the exact purpose its being used for.

  • Indirect data is derived from data originally collected for an entirely different purpose.


Direct data
Direct Data

  • Information collected is exactly what the organisation wants.

  • Organisations can be sure of the reliability of the data, because they specify what is needed.

  • Data can become a valuable commodity if re-sold as indirect data

  • The organisations collecting data must pay all the costs related to collecting it.


Example of direct data
Example of Direct Data

  • Suppose Omagh’s traffic light system is being upgraded. Before this , Road services require information such as how many cars use the road in question and at what times of day. If no one already has this information t must be collected. This data is collected specifically for Roads services in order to access traffic management. Therefore this is an example of direct data.


Indirect data
Indirect Data

  • The information available depends on what was originally collected.

  • Data coming from a third-party can contain much unnecessary material.

  • It can be difficult to know how reliable the original data was.

  • The organisation wanting data may pay only a fraction of the original cost of collecting it.


Example of indirect data
Example of Indirect Data

  • Census figures which are used by education authorities to plan how many teachers will be needed in schools in thr years ahead.
