Q:  

My company has finished the first phase of a data warehouse, with total size of about 100GB. The company then estimated that the warehouse would grow to about 3.75 terabytes of data, with the largest table being 100 million rows. After some research, the company identified the following RDBMS candidates for the task: NCR Teradata, Oracle 8i, IBM DB2. Can you make a recommendation or eliminate any candidates?
