The origin and evolution of temporal models
The need to preserve individual states and limit them over time arose with the advent of the first database systems in the 1960s. Several ideas were brought forward for managing and modeling these types of data, with an emphasis on validity, but most of them were only treated theoretically. The main limitation was the technical support costs in terms of the hardware components, limiting the possibility of the further expansion of technical equipment.
A more significant shift occurred during the boom of relational database systems. They are based on entities and relationships, creating a data model separate from the physical hardware. The main features are integrity, individual rows being identified by primary keys, as well as the precise structure supervised by transaction support. Moreover, individual structures can be optimized using the process of data normalization to maintain efficiency and data quality. The data access itself is...
