2>History of Oracle:

Oracle was first developed in the late 1970s by Larry Ellison, Bob Miner, and Ed Oates. It was initially called Software Development Laboratories (SDL), but later renamed to Relational Software, Inc. (RSI) and then to Oracle Corporation in 1982. Since then, Oracle has become the world's leading DBMS, with a market share of over 30%.

3>Key Features of Oracle:

Oracle offers a range of features and functionalities that make it a powerful and versatile DBMS. Some of the key features include:
