The term `data' has a variety of meanings but in the context of this publication, it is simply information that an organisation, either has to, or wants to retain. Power network companies in particular maintain extensive databases of information, which are essential for the running of the company. Much of this information is originated during the construction process, and much is additionally held by contractors and manufacturers, for their own purposes. This chapter will review salient items of data which arise during power network construction, with a view to examining: 1.The purpose of data management 2.The range of data retained 3.Reasons for retaining the data 4. Data management procedural requirements. As such, both an absence of data or incorrect data can be a significant risk both to the well-being of the company, and the security of electricity supply.
