Teradata was the first to announce a database that could handle 1TB of data. They developed a database that was built to work on a massively parallel scale and hence the high speeds in working with large volumes of data. Teradata was (for at least five years in succession) one of the fastest growing company at that time.
IBM published “Information Warehouse” framework as early as 1987 and hence can be regarded as the other pioneer of data warehousing.
Enterprise Data Warehousing has been the key trend in corporate computing in the 1990s and continues to be so today.
