Q1.

Create a website for a Bank which offers online Banking service to its registered customers. The website should be designed using logical divisions through

tags and an external CSS file. Every page of the website is divided into four divisions namely – Main, Cpyrt, Options and Data as displayed in the following figure:

Perform the following tasks for the website as given above:

[ Part (a) : 10 Marks + Part (b) : 05 Marks + Part (c) : 05 Marks + Part (d) : 20 Marks]

(a) Create four pages for the website viz Home, Account Balance, Transactions and Feedback; all the four pages should have same Main, Options and Cpyrt division but different Data division. The Options Division should provide links to the Home page as well as all the other three pages. All these four options should be available in all the web pages designed by you for this assignment. Thus, this Option division may be used for navigating among the four web pages. The Data Division of every page should be different. The information that should be displayed in Data Division of each of the pages is described below:

(i) The Home page should display the list of services available through these pages.

(ii) The Account Balance page should display a form for logging into the Database of the Bank.

(iii)The Transactions page should display the transactions of the account for which Balance has been shown.

(iv)The Feedback page should display another form having a text area field for writing the Feedback and a Button to submit the form.

(b) Create an external CSS that gives different background colour to each division. You may choose the format of other elements as per your choice. (c) Create a JavaScript program that generates an error message if Username field is left blank in the form for Account Balance page; or if the length of entered password in the password field is less than 4 characters . After displaying the error message, the login form should be displayed again.

(d) Implement the following using jsp program, servlets, java classes, database(s), etc. for the pages as described below:

(i) When a user presses Submit button after properly filling Username and password in the form in the Account Balance page, these details are checked in a database and in case such username and password are correct, the account number, account holder name and balance of the account are displayed on the screen. You may also create a cookie, if needed, to remember the account number for the given username and password (assuming each user has only one account).

(ii) On selection of Transactions option, all the transactions made (assume only Deposit and Withdrawal transaction) for the account number, as remembered in part (d)(i) above, is displayed in a tabular format.

(iii) When you press the Submit button of the Feedback Form, the information (account number from the cookie and entered text) should be stored in the database.

(iv)You must design a suitable database structure.

You may make suitable assumptions, if needed

Ignou solved assignment for BCS-055 Business Communication

This assignment has 8 questions. Answer all questions. Please go through the guidelines regarding assignments given in the Programme Guide for the format of presentation of assignment.

Q1. This passage is part of the speech that Oprah Winfrey (a famous American television personality, actress, and entrepreneur) gave at the convocation in Harvard University, USA. Read the passage carefully and answer the questions given below:

This is what I want to share. It doesn’t matter how far you might rise. At some point you are bound to stumble because if you’re constantly doing what we do, raising the bar. If you’re constantly pushing yourself higher and higher, the law of averages predicts that you will at some point fall. And when you do I want you to know this, remember this: there is no such thing as failure. Failure is just life trying to move us in another direction. Now when you’re down there in the hole, it looks like failure. And when you’re down in the hole, when that moment comes, it’s really okay to feel bad for a little while. Give yourself time to mourn what you think you may have lost but then here’s the key, learn from every mistake because every experience, encounter, and particularly your mistakes are there to teach you and force you into being more who you are. And then figure out what is the next right move. And the key to life is to develop an internal moral, emotional G.P.S. that can tell you which way to go. Because now and forever more when you Google yourself, your search results will read “Harvard, 2013”. And in a very competitive world that really is a calling card because I can tell you as one who employs a lot of people when I see “Harvard” I sit up a little straighter and say, “Where is he or she? Bring them in.” It’s an impressive calling card that can lead to even more impressive bullets in the years ahead: lawyer, senator, C.E.O., scientist, physicist, winners of Nobel and Pulitzer Prizes or late night talk show host.

But the challenge of life I have found is to build a résumé that doesn’t simply tell a story about what you want to be but it’s a story about who you want to be. It’s a résumé that doesn’t just tell a story about what you want to accomplish but why. A story that’s not just a collection of titles and positions but a story that’s really about your purpose. Because when you inevitably stumble and find yourself stuck in a hole, that is the story that will get you out. What is your true calling? What is your dharma? What is your purpose? For me that discovery came in 1994 when I interviewed a little girl who had decided to collect pocket money in order to help other people in need. She raised a thousand dollars all by herself and I thought, well if that little 9-year-old girl with a box and a big heart could do that, I wonder what I could do? So I asked for our viewers to take up their own change 14 collection and in one month, just from pennies and nickels and dimes, we raised more than three million dollars that we used to send one student from every State in the United States to college. That was the beginning of the Angel Network.

1a Why does Oprah feel that everyone no matter what their qualifications or competences will encounter failure? Pick out the line.

1b What should a student/person do when faced with failure?

1c What does the speaker mean by “And the key to life is to develop an internal moral, emotional G.P.S. that can tell you which way to go”?

1d What have the former Harvard graduates achieved according to the passage?

1e What is the “true” resume that the students should build in their lives?

1f What have you learnt from this passage and how would you implement it in your own life?

1g Give a title to the passage.

1h Use the following words/phrases from the passage in sentences of your own:

share, rise, stumble, raising the bar, the law of averages, down in the hole, challenge, accomplish, a big heart, wonder

Q2. Insert responses in the following conversation:

You: …………………………………………………….
