CS403 GDB Idea Solution

Just take the idea not copy paste

Question:-

When data is manipulated, the indexes have to be updated. This slows down data manipulation.

Answer:-

Search engine indexing collects, parses, and stores data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics, and computer science. An alternate name for the process in the context of search engines designed to find web pages on the Internet is Web indexing. So doing all this operation indexes have to be updated which causes slow manipulation. Because this operation causes the index to be modified and requires additional updating of each index on that table, SQ L has to internally maintain the “pointers” to the inserted rows in the actual data file, each index potentially adds an alternative access path for a query for the optimizer to consider, which increases the compilation time.

Dear students,

A Graded Discussion Board for 'E-Commerce (IT430)' will be opened on Monday 31 January, 2011and it will be closed on Tuesday 01 February, 2011.

Discussion Topic

From consumers' point of view trust and satisfaction are two most important aspects of E-Commerce. In your opinion, which factors can be more critical to the internet consumer regarding trust on an E-Commerce portal?


Read the instructions carefully before sending your comments:


1. GDB will have weight-age of 5% of your total subject marks.
2. Your discussion must be based on logical facts.
3. You should post your comments on the Graded Discussion Board & not on the Regular MDB. Both will run parallel to each other during the time specified above.
4. Your comments should be relevant to the topic i.e. clear and concise (Maximum 5-8 lines answer).
5. Books, websites and other reading material may be consulted before posting your comments. (Do not copy the material as it is.)
6. No extra time will be given for discussion.
7. You cannot participate in the discussion after the due date or through e-mail.

SOLUTION:

As from the question we can see that two things are asked from us as E-commerce analyst that which one is most important priority vise. It is understood that if a internet consumer is going to purchase he/she first trust on the site after that the internet consumer will get the product and will be satisfied that this product is working fine for him/her. So most important is the trust. To get trust most of the sites use SSL certificate for security which helps and shows the credibility of the site its secure for the online payment. One more thing which is the VeriSign authentication services. So trust is more important as compare to satisfaction.

Topic/Area for Discussion

"Business Plan"

................

SOLUTION:

Question/Description

Ahmed wants to purchase a departmental store from one of his family friends. Ahmed does not think he needs to write a business plan because it is a running business. Do you agree or disagree with his opinion? Why or why not?

Business plan:-

A written document describing the nature of the business, the sales and marketing strategy, and the financial background, and containing a projected profit and loss statement of a new or a running business is called Business Plan.

I disagree with Ahmad’s opinion because:

Business Plan is essential for a running Business to keeping the business up-to-date, to introducing any new products or restructuring, to get started expenses and to keeping the long term business success.

................

I disagree with his opinion. He has to write a new business plan. The reasons are as following:

Existing plan was not prepared by Ahmad and it’s old also so there can be many aspects that he would like to change. Business plan must be re-written with updates. Strategies of running business operations, market situation must be analyzed and operations of business must be reviewed, significant and needed changes must be made. Relationship with Suppliers may not be good so he have to make new policies and new terms of credit and payment with the suppliers. Management structure would be changed to make the business more efficient. Customer relationship and satisfaction level may not be much good or developed so Ahmad must include these all aspects in his own business plan.

Existing personnel may be not experienced and relationship with them may be conflicting so he will have to make strategies for hiring new workers, their pays timing must be specified. Sources of finance, Ahmad have to identify and specify his sources of finance from he can get financial assistance and they will be different from his friend’s sources. Profit expectations of Ahmad may be different from his friend so strategies for profit maximization must be explained in his own business plan. So there may be so many changes that the existing business plan has to be replaced with new plan.

...............

Yes I agree with the statement. As it is a running business and Ahmad’s family friend’s business on whom Ahmad can trust so it’s not necessary to make a new business plan. Reasons can be Plan is already in operation and if you will implement a new business plan it will disturb the routine of the business. And it will take time to develop a new plan and then implementation will also take time this will effect the operations, cash flows of business. The customers and employees are also there and when you implement the new plan they may not like it in this way you can lose existing customers and personnel, losing experienced workers can be a big loss. Relationship with suppliers, and finance providers is already developed and in operation if you implement the new plan it will take time to rebuild the relations with suppliers and financial assistance providers.

So due to these reasons Ahmad must run business with existing plan.

...........

In my opinion, Ahmed should write a new business plane with his perception because he may have different business objectives from previous plane which is already running. He is performing as an entrepreneur Ahmed has to develop new strategy about credit polices, specifying the sources of finance, customer relationship management, inventory management.

The written business plan can be very helpful for ahmed because:

1. It gives the guidance in planning activity
2. It serves an important tool to obtaining finance
3. It also provides him a self assessment.

............

in my opinion he should write the business plan

I. Why Write a Business Plan?

Why should a business go through the trouble of constructing a business plan? There are five major reasons:

1. The process of putting a business plan together forces the person preparing the plan to look at the business in an objective and critical manner.

2. It helps to focus ideas and serves as a feasibility study of the business's chances for success and growth.

3. The finished report serves as an operational tool to define the company's present status and future possibilities.

4. It can help you manage the business and prepare you for success.

5. It is a strong communication tool for your business. It defines your purpose, your competition, your management and personnel. The process of constructing a business plan can be a strong reality check.

6. The finished business plan provides the basis for your financing proposal.

Planning is very important if a business is to survive. By taking an objective look at your business you can identify areas of weakness and strength. You will realize needs that may have been overlooked, spot problems and nip them before they escalate, and establish plans to meet your business goals.

The business plan is only useful if you use it. Ninety percent of new businesses fail in the first two years. Failure is often attributed to a lack of planning. To enhance your success, use your plan! A comprehensive, well constructed business plan can prevent a business from a downward spiral.

Finally, your business plan provides the information needed to communicate with others. This is especially true if you are seeking financing. A thorough business plan will have the information to serve as a financial proposal and should be accepted by most lenders.

If you have decided to start your own business, one of the first things that you need to do is to work on a business plan. A business plan is so important because it actually serves as a compass for the direction your business will take in the future. Having a plan will also help you achieve the things you want to achieve and will help your business to find success as well.

Consider the Details

One of the reasons that having a business plan is essential is that it will help you to consider the details of your business and its' future. As you are working on your plan, you will probably find that there are many aspects of your new business that you have not considered. Getting started with a business plan will help you to save money and time since you will be able to deal with issues before they become a problem.

Helps You Get Funding

Another great reason for having a business plan is that it can help you if you are trying to get outside funds for your business. Most lenders and investors want to see that you have a clear business plan before they take a risk on your business. Having a plan already drawn up shows them that you are serious about being successful at your business. If you are going to show your business plan to potential lenders and investors, make sure that the figures you use are accurate so your plan is credible.

Management Tool

Starting a business is a huge job and it is helpful if you have something that can help you manage the business. A business plan can act as a management tool that can help you focus on where you are and where you want to be in the future. This will help you to keep your daily tasks well managed and will also help you to accomplish long term goals as well.

If you decide to go without a business plan, chances are that your business is going to end in disaster. You can use a business plan throughout all stages of your business to guide your business towards success. While it may take some time and energy to get a business plan together, in the end it will be well worth taking the time to get it done right

With the name of Almighty, dears we’re to discuss the calculus application in the field of our practical life.

First me have to say that “Calculus” is that branch which deals with the integral calculus e.g. calculation area under the curve and the deferential calculus that deals with the motion calculation, and that all are the part of our practical life. Calculus is deeply integrated with the physical science and such as physics and Bio science, so now we can say that it is more important in every aspects of life some of them we’ll here discuss.

It is found in computer science, statistics, and engineering; in economics, business, and medicine. Modern developments such as architecture, aviation, and other technologies all make use of what calculus can offer. Graph visualization are also based on that, we can easily graph the function with the help of it. Finding average of function one example is the path of an airplane. Using calculus you can calculate its average cruising altitude, velocity and acceleration.

So at the end that branch cover a lot of area of our practical life to overcome them we’d have good knowledge of it.

Another:

"Why do we study calculus,write its at least three applications"

Graded Moderate Discussion will be open on Calculus is Latin for stone, and the ancient Romans used stones for counting and arithmetic. In its most basic sense, calculus is just that a form of counting. After advanced algebra and geometry, it is the next step in higher mathematics, and is used for solving complex problems that regular mathematics cannot complete.

Calculus is the mathematics of change, of calculating problems that are continually evolving. This is possible by breaking such problems into infinitesimal steps, solving each of those steps, and adding all the results. Rather than doing each step individually, calculus allows these computations to be done simultaneously.

Calculus is useful for solving non-linear equations. For example, say you were looking for the area inside a flat rectangle.

Calculus is deeply integrated in every branch of the physical sciences, such as physics and biology. It is found in computer science, statistics, and engineering; in economics, business, and medicine. Modern developments such as architecture, aviation, and other technologies all make use of what calculus can offer. This page is designed to out line some of the applications of calculus and give you some idea of why calculus is so important and useful.

Calculus can give us a generalized method of finding the slope of a curve. The slope of a line is fairly elementary, using some basic algebra it can be found. Although we do have standard methods to calculate the area of some shapes, calculus allows us to do much more. A function can represent many things. One example is the path of an airplane. Using calculus you can calculate its average cruising altitude, velocity and acceleration.

Windows Foundation Classes for Java (WFC) provides a framework of Java packages that support components targeted for the Microsoft Windows operating system and the Dynamic HTML object model. WFC is tightly integrated with the Microsoft Visual J++™ development environment and provides a full set of Windows controls written in Java. Building a Java application for Windows is made much easier by this tight integration and the support of features such as IntelliSense, the Forms Designer, the Application Wizard, and the Object Browser. While these Visual J++ features put you well on your way to creating applications, you'll probably want to understand the structure and logic behind the packages and classes that make up WFC.

The purpose of this section is to provide a conceptual framework for the WFC packages and classes and to explain some of the fundamental WFC models. Many of the packages exist as infrastructure for the component model and can be ignored by developers focusing on using the WFC controls. Other packages are most easily accessed from the Visual J++ Forms Designer. When you start exploring the WFC library, you'll want to know which packages and classes are important for your particular application.

.................

First thing about Windows - it is a multi-tasking environment. That means that it can actually run more than one program at one time, giving you higher efficiency. You'll need to process code for each program simultaneously, which is no easy feat. So, the makers of Windows created a system where each program was like a procedure - code was run only when the system requested for it. This meant that they needed to create a whole new system for Windows, containing the API (Application Program Interface). Code was in the form of 'events'. Only when an event occurs will code be run. Now you know why Delphi makes you type code that way!

* WFC Packages provides a high-level overview of the main packages that make up WFC.

* Working with WFC Visual Components describes the controls, forms, and graphical objects in WFC, which include the following subtopics:

o Windows Visual Components

o Dynamic HTML Visual Components

* Handling Events in WFC describes the use of delegates for handling events.

* Localizing Your Application describes the Visual J++ and WFC support and methodology for localizing your project in various languages.

* Using WFC Application Services describes some of the core application features and includes the following subtopics:

o Starting and Quitting an Application

o Handling Application Events

o Accessing System Information

o Performing Clipboard and Drag-and-Drop Operations

* Using Java Threads with WFC describes the threading model for WFC and includes the following subtopics:

o Mixing Java and Win32 Threading Models

o Creating and Exiting a Thread

o Using Thread Storage

o Working with Thread Exceptions

Construct a real world business problem and then apply simple linear regression analysis.

Question:-

Suppose that 4 randomly chosen plots were treated with various level of fertilizer in the following yield of corn:-

Fertilizer(kg/Acre) X 100 200 400 500

Production(Bushels/Acre) Y 70 70 80 100

Estimate the Linear Regression of production Y on fertilizer X.

Solution:-

X Y XY X2

100 70 7000 10000

200 70 14000 40000

400 80 32000 160000

500 100 5000 250000

å = 1200 å = 320 å =103000 å = 460000

Byx = nåXY – åXåY / nåX2 - (åX) 2

Byx = 4(103000)-((1200)(320)) / 4(460000)-(1200) 2

Byx = 0.07

ayx = y - Byx X

= ((åY/n) – ((0.07) (åX/n))

=(320/4) – (0.07)(1200/4)

= 59

y = 59 + 0.07 X is required regression equation.
