STEPS TO DEVELOP A SEQUENCE DIAGRAM
1.Identify all objects and actors that are involved in a scenario. Use only actors identified in the use case diagram. Use only objects identified in the class diagram.
2.Based on the flow of activities, identify each message that will be required to carry out a scenario and identify the source of the message
a.Identify the object that needs the service
b.Identify the object that has access to the required input parameter.
c.Usually a one to many association in the class diagram, the object on the one side will create and send messages to the object on the many side.
3.Determine whether each message is always sent or is sent only on certain conditions.
4.Sequence the message correctly and attach them to the lifelines.
5.Add the formed syntax on message to describe conditions, message names, and passed parameters.
6.If desired, add the response messages and communications to make the sequence diagram complete.
ACTIVITY
Identify the 2 possible scenarios and develop a flow of events for each.
Quality Building Supply has two kinds of customers – contractors and the general public. When a contractor checks out materials, he or she takes them out to the contractor check out desk. The clerk scans in the items to be purchased. The system creates electronic ticket for the items. The system compares the total amount against the contractor's current credit limit, and if it is acceptable finalizes the sale. Once a month the system sends and invoice to the contractor and when payment comes in increases the credit limit back to the original value. The electronic ticket is maintained in the system and can be printed out at any time for the ff. 60 days. Some contractors ask for a printout, some will not. A sale to the general public is simply entered into a cash register. Payment can be a cash, check or credit card.
The clerk must enter the type of payment to ensure that the cash register balances at the end of the shift. For credit card payments, the system prints out a credit card voucher that the customer must sign.

Am I an IT Professional?
There are many issues with regards to the statement “Are IT Professionals, Professionals?” What is really the basis of calling one’s profession as professional? Well, there are many questions and thoughts that encompasses the issues on what we called “IT Professional” and I am also asking myself am I an IT professional?
When I was in college, in our Ethics and Professionalism subject, this is one of basic topic we’ve taken up. We based our discussions in the book Ethics in Information Technology Book by George Reynolds. In that book, we have read and allow me to quote it right now -The United States Code of Federal Regulations [29 CFR Sec. 541.3] defines a person “employed in a professional capacity" as one who meets these four criteria:
1. One's primary duties consist of the performance of work requiring knowledge of an advanced type in a field of science or learning customarily acquired by a prolonged course of specialized intellectual instruction and study or work.
2. One's instruction, study, or work is original and creative in character in recognized fields of artistic endeavor and the result of which depends primarily on the invention, imagination, or talent of the employee.
3. One's work requires the consistent exercise of discretion and judgment on its performance.
4. One's work is predominately intellectual and varied in character and is of such character that the output produced or the result accomplished cannot be standardized in relation to a given period of time.
Also, from the WIKIPEDIA the following information is gathered:
A 'true' professional must be proficient in all criteria for the field of work they are practising professionally in. Criteria include following:
1. Academic qualifications - a doctoral or law degree - i.e., university college/institute
2. Expert and specialised knowledge in field which one is practising professionally
3. Excellent manual/practical and literary skills in relation to profession
4. High quality work in (examples): creations, products, services, presentations, consultancy, primary/other research, administrative, marketing or other work endeavours
5. A high standard of professional ethics, behaviour and work activities while carrying out one's profession (as an employee, self-employed person, career, enterprise, business, company, or partnership/associate/colleague, etc.)
Basing on the mentioned criteria, I would answer the question Am I an Information Professional? Yes I am an IT Professional. My basis?
• I am academically qualified since I finished the degree of Bachelor of Science in Information Technology and with that I have acquired knowledge that helped me in my work right now.
• I have my own specialization and expertise that helps me to create an artistic endeavor in any field of work I am into. I am practicing and developing my specialization through the academe.
• It has been always my aim to do high quality of work in the services and endeavors undertaken. With that high quality of work I am keen that I am practicing right judgment for my work’s performance.
• I am aware and practicing the ethical guidelines in the academe where I belong to. I am trying to perform the duties and responsibilities of an instructor with the awareness of what is right and wrong.
These are all folks have a nice vacation.

I thought it's EASY but NO it never was..
Good morning guys... Today is Friday, January 30, 2009 and tomorrow is our class.. . Finished the assessment???? Well, I'm not yet done...
At first glance, the assessment seems to be easy(right???) There's a thought in my mind that OH... I've been to this application!... but when taking the assessment I realized it's kinda DIFFICULT..
What makes it difficult??? well, it's tricky, if you won't read instructions you won't be able to do the way the assessment has been programmed.. . as many people said," there are various ways in killing a cat"- (just like "copy" , you can use the menu bar or the toolbar or the Ctrl + C and etc.-but in the assessment you really need to do what is the one click way of performing a task). One wrong click has a big effect in the score....ohhhh! It would really take hours in taking one assessment... .
And what's my SCORE???? not so excellent, but it's a passing score.. But it's worth it.. this is what I can do.. .
Well, there are still so many things to learn in my journey!

...FUTURE :)
Hello everyone.. This is my first post! whewwww... I am li'l bit confused what to write..
"WONDERING WANDERER" this is my blog title.. you may wonder why.. hmmm.. It's simply because I am still in my journey with an unknown destination here on earth and as I walk along I have many questions that need answers.
In our present generation, we are beneficiaries or users of technology which makes possible the impossible of the last decades. Through IT we have reached this far-in our studies and in our career.. from year to year, the world of IT evolves.. What will be the future of IT??? Could there be a possibility that technology could help us predict our life's future.. ??? In that case, we could be aware when to die, where to go the next years and the possibility of choosing our own way instead of following what is predicted.. these are just few of the many questions I had...
Yes, my future is unknown, I am entrusting my life to the Master Creator, serving Him with joy and thanksgiving.. I still believe in the great power of the Almighty who holds my future and who knows my tomorrow. .
