2. Multiple choice. Circle the correct (or the best) answer. Circle only one answer. Multiple circles will be considered as wrong answer. No explanation needed. No partial credit will be given. (i) Comparing RDB, OODB and ORDB, we have learned that (a) RDB provides simple data types, restricted query languages, and high protection. (b) Persistent programming language based OODB provides complex data types, advanced integrity constraints, and powerful query languages. (c) ORDB system provides complex data types, powerful query languages, and high protection. (d) All of these three: RDB, OODB and ORDB support multiple inheritance. (e) None of the above. (ii) Studying XML in a DBMS course is important because (a) Although XML may be dying, it is not dead yet. (b) XML is a more powerful markup language than HTML. (c) XML can encapsulate subelements to form objects, so it has the power of OODB. (d) XML is a good example of studying storage and manipulating semi-structured data, and facilitating data exchange in a networked environment. (e) None of the above. (iii) The following is true about RDB, ORDB and XML (a) Any data can be stored in an RDB can also be stored in an ORDB. (b) Any data can be stored in an RDB can also be stored as an XML document (although integrity constraints are lost). (c) Any data can be stored in an ORDB can also be stored as an XML document (although integrity constraints are lost). (d) All of above (a)(b)(c) are true. (e) None of (a)(b)(c) is true.
