Quiz Week 13 Object DMBS Team G38 Connor Ferris, Anand Rajan Example “Consider the challenge posed by an airborne warning and control system (AWACS) (Figure 1) that divides database processing between real-time, embedded in-memory database systems (IMDSs) residing in one or more data acquisition modules, and an enterprise-class application and DBMS that run on a high-powered server and are responsible for carrying out primary mission tasks such as surveillance, communication, and command and control” TL;DR -> AWACS uses DBMS to do cool stuff. Question 1 Which of the following requires object database technology? A. Storing employee picture on disk B. Retrieving an employee picture C. Retrieving and processing an employee picture together with simpler data C. Retrieving and processing an employee picture together with simpler data A and B could be accomplished with a hard drive and GIMP. Question 2 Which of the following supports object oriented concepts? A. SQL1 B. SQL2 C. SQL3 D. All of the above D. All of the above Question 3 Object in pure object oriented languages hide the implementation details, e.g. attributes and internal procedures, from external world. This properties is called: A. Abstraction B. Encapsulation C. Inheritance D. Polymorphism B. Encapsulation Question 4 Which of the object concepts are usually not implemented in today’s object relational DBMS because of the serious performance concerns? A. Data abstraction B. Encapsulation C. Inheritance D. Methods (i.e. procedures) D. Methods (i.e. procedures) Question 5 Which of the following do not apply to today’s object relational DBMS? A. Calls to functions that process media data are part of the database language B. Specialized storage structures are provided C. Reliability is of no concern D. Combined access to complex data and relational data is optimized C. Reliability is of no concern Discussion Question Which object DBMS architecture do you think will dominate in five years? Mannino says SQL:2008 or Oracle g11 and beyond following the object-relational approach.
