Question: Investigate any system that might be available to you. What programming language does that system support? Does it support a query language? If so, what is it? In your opinion, is it more or less powerful than conventional SQL? Does the system support versioning and configurations? If so, what is involved on the part of the user in managing versions and in interrogating version histories? Does the system support long or nested transactions? Does the system have any schema evolution capabilities? What does the catalog look like? How does the user interrogate the catalog? Is there any view support? If so, how extensive is it? (e.g., what about view updating?) How is missing information handled?
