If there is no clear specification for what data is of interest to an organisation, it will be far harder to ensure that the quality of data meets your organisation’s requirements. A data dictionary can help ensure that all relevant stakeholders understand the data required by an organisation and the meaning of that data. DPA are able to support you in developing an agreed data dictionary.

The concept of a data dictionary is relevant for both tangible and non-tangible assets, such as information on clients, financial data, etc. It must make clear what data needs to be captured, managed and made accessible to deliver the information requirements. A data dictionary is a recognised way to hold and manage the data requirements; it can also be known as data specification or data design.

Data quality processes are a key part of managing data, whilst a data dictionary does not deliver quality data on its own it is a fundamental start point in understanding the ‘What’ is required. A data dictionary may be used to hold the criteria that identifies whether data is fit-for-purpose.

The illustration below shows how a physical asset, in this case a fan, will have relationships with other objects and entities. The Data Dictionary will help to define valid relationships that should be recorded.

DPA have successfully run data dictionary creation projects for several large organisations including the implementation of governance processes to manage and control change over the dictionary content.
