Question: Michael Stone braker and Lawrence A. Rowe. "The Design of POSTGRES." Proc. ACM SIGMOD International Conference on Management of Data, Washington, D.C. (June 1986). The stated objectives of POSTGRES are:
1. To provide better support for complex objects
2. To provide user extendibility for data types, operators, and access methods
3. To provide active database facilities (averters and triggers) and inferencing support
4. To simplify the DBMS code for crash recovery
5. To produce a design that can take advantage of optical disks, multiple-processor workstations, and custom-designed VLSI chips
6. To make as few changes as possible (preferably none) to the relational model
