Someone, anyone, please answer this question

| You want to implement OLPT in an e-commerce Business application. Which of the following is needed:
a.Object oriented database
b.XML
c.Relational database *******
d.Object Request Program
Here's what we know so far.
OLPT - On Line Transaction Process..... Handling real-time transactions such as those that stock exchanges and airline reservation systems require. Such systems require transaction management, extensive audit trails, routing, scheduling, and administration.
OK. Great. I say because the the question asks; "Which of the following is needed...for the business app????"....It needs a relational database.
Relational Database - A database or database management system (RDBMS) that organizes data and relations between the data in tables made up of columns and rows of data (Visual Basic refers to columns as fields, and rows as records). Relational databases enable the definition of data structures, storage and retrieval operations, and integrity constraints. Certain fields may be designated as keys, which means that searches for specific values of that field will use indexing to speed them up. Records in different tables may be linked if they have the same value in one particular field in each table.
OLPT is related to "transaction servers". That is how I found it on the web. Transaction Servers are related to "Relational Databases."
Types in "Relational Database" for a keyword search, and up pops OLPT.
Bottom line; is C the correct answer?
Just my two cents. This is not a question that would be answered by anyone other than a person who has his dreams in C++ code and lives and breaths database development.
Thanking you in advance.

| Phantom,
Good luck with your exam.
Just from my random notes, you may just find them useful.
1) URL consists of the protocol that is used to access the document and the domain name or IP address of the host that holds the document...
2) “Like other weak cryptosystems, DES and other encryption systems are exportable without key recovery, at the weak key lengths of 40 bits or less while robust encryption, such as the 128-bit IDEA algorithm used by the PGP security product, remains subject to export restrictions…”.
DES is in for international use, as there is the 40 bit version; but PGP is definitely out...
3) according to Sybex N+ Study Guide, “192.168.xxx.xxx is an address specified in rfc 1918 as being available for anyone who wants to use IP addressing in a private network, but does not want to connect to the Internet…”
4) ExamNotes claims "Browser safe palette" consists of 216 colors...
Why 216 and not 256 colors supported by GIF? Turn out it may have something to do with MAC---hence the ExamNotes comment, "These colors are displayed the same way in any browser on any OS platform". MAC,the OS is different from Windows when it comes to color...
5) From Examnotes: TIFF file format (Tag Image File Format) is normally used for graphic files that are black and white...To view the TIFF files on your browser you need to install a TIFF viewer plugin...
