Businesses in the database activities category organise, manage and provide access to collections of information stored in digital databases. They may design database structures, convert paper or existing records into searchable formats, check and update data, and maintain systems so information can be retrieved, amended and backed up. Some specialise in particular types of information, while others provide general database management or data-processing services for organisations. Customers may use these businesses to build or maintain a database, combine information from different sources, create search tools and reports, or arrange secure storage and controlled access for users. Services can also include database hosting, routine maintenance, software configuration, data migration and technical support. Providers may supply access to information through a subscription or licence, subject to applicable data protection and intellectual property requirements.
