There are both technical and business aspects of database technology to discuss here. The birth and the needs of a separate database system had both a business and technical reasons. Among the first official software standards, beyond programming languages, were different database standards of the 1960’s. The 1970’s saw the emergence of the relational model, and the mathematical and theoretical background here is both interesting and if not unique so at least uncommon.
The development of SQL databases during the late 1970’s and early 1980 changed the world of database systems completely, and together with other technology changes of those days, such as the emergence of standardized operation systems (most prominently Unix) and the Personal Computer, would transform the climate for compting completely.
As the storage capacities of even small computers grew, the potential and uses for databases grew. The PC oriented database systems, simple and working well on small PCs, largely disapperad as PCs became more powerful and above all networked.
The 1990 saw the emergence of the Internet, and again the means and needs for accessing data changed, as so did the database systems. Those years also saw data warehousing grow to something everyone could potentially use and benefit from.
Over many of these periods, SQL has managed to stay put longer than most other technologies. Something that grew out of mainframes 40 years ago is still with us. This is a fact that should also be debated. Are are we now, finally, seeing the end of SQL?
