Although technically the term data refers to the streams of 1s and 0s that, when decoded, convey information in the form of words, letters and numbers, we often find ourselves using the term data to refer to the information contained within an electronic filing cabinet, a database. Big Data is a term that has fallen into misuse, with organisations claiming they use Big Data when they often just mean lots of data. If you are dealing with such large volumes of data that you cannot handle them through normal means, then you probably are working with Big Data. That is to say, if you are collecting and storing large and/ or expanding volumes of data from one or multiple sources that cannot be processed using your existing traditional data processing application software, then you are using Big Data. While we are dealing with the more confusing of the terms, we will introduce digital. In common use, the terms ‘data’ and ‘digital’ are muddled, but we will try to stick to data systems for a content-related context and digital systems for a hardware or infrastructure-related context. Data sits on digital systems, which follow the design principles laid out in a digital strategy. Data products and data services are easier to define, with a data service being the intangible version of a data product. Managing data falls in the realm of the data manager, although overall responsibility for all things data may lie with a chief data officer (CDO). The data manager has a close relationship with the data he or she manages, and a responsibility to make sure that the data quality and other characteristics of the data are fit for purpose with the organisational use of data. Data management tasks include putting in place the tools, frameworks, storage facilities, policies, practices, systems and so on to ensure that data is accessible and available in line with organisational requirements, as defined and stipulated by the data owners. Data stewards sound as though they might also be data managers, but their role is more focused on championing the correct use of data and protecting against unauthorised use. Ironically, the data stewards in an organisation generally spend more of their time with the people (data users) than the data itself.
