• REFERENCE PERIOD:  Period to which the information refers and which may be a specific day or a time interval (month, fiscal year, calendar year, among others).
• ENTERPRISE:  Legal entity (natural or legal person) that is an organisational unit producing goods or services, which benefits from a certain degree of autonomy in decision-making, especially for the allocation of its current resources. An enterprise carries out one or more activities at one or more locations.
• TECHNOLOGICAL PRODUCT INNOVATION:  The term "product" is used to refer to goods and services. Technological product innovation can be of two types: technologically new products and technologically improved products: a) A technologically new product is a product whose technological characteristics or intended use differ significantly from those of previously produced products. These innovations may involve radically new technologies, be based on new combinations of existing technologies, or result from the application of new knowledge; b) A technologically improved product is an existing product whose performance has been significantly extended or developed. A simple product can be improved (in terms of better performance or lower cost) by using components or materials with more advanced technical characteristics. A complex product, made up of an integrated set of technical sub-systems, can be improved through partial changes to one of the sub-systems.
