b. How are events synchronization and data representation handled during a session of face-to-face conversation, such as when you speak to someone seated next to you?
Consider inter-human communications.
Event synchronization is effected using pauses, eye contact, gesture, or explicit words (“hello”,“your turn”, “I AM talking”).
A session is initiated when two persons come in contact, and one or both signal to each other his/her desire to converse (‘hello, how’s it going?’) The conversation takes turns between the participants. A change in turn may be signaled by a pause, eye contact, gesture, or explicit words (“what do you think?”). It is imprecise, however, as people do sometimes talk at the same time, or awkward pauses may occur in the midst of a conversation.
Data representation: a common language (possibly sign language) will have to be spoken, or a language translater will be needed. The sound is carried by air to all within earshot or sight of the speakers. Additionally, data can be encoded using body language, tone, facial expression, and gestures.

Which of the following is a more precise way to define the content of an XML document?

Consider the relational schema in Figure 3.6. Assume that the Web server delivers the contents of these relations using the following XML format: the name of the relation is the top-level element, each tuple is represented as a tuple element, and each relation attribute is represented as an empty element that has a value attribute. For instance, the Student relation would be represented as
follows:
Formulate the following queries using XQuery: a. Produce the list of all students who live on Main Street. b. Find every course whose CrsCode value does not match the Id of the department that o?ers the course. (For instance, the course IS315 in information systems might be o?ered by the Computer Science (CS) Department.) c. Create a list of all records from the Teaching relation that correspond to courses taught in the fall semester.
