What-If Analysis

What-If Analysis Introduction The real power in Excel comes in its ability to perform multiple mathematical calculations for you. One of the tools in Excel that you can use to perform these calculations is a Data tool called What-If Analysis . What-If analysis allows you to see the effect that different values have in formulas. Have you ever thought, "What interest rate do I need to qualify for to have a car payment of $400 on the car I want?" This question can be answered using What-If Analysis. In this lesson, you will learn how to use a What-If Analysis tool called Goal Seek . Example You need a loan to buy a new car. You know how much money you want to borrow, how long of a period you want to take to pay off the loan (the term) , and what payment you can afford to make each month. But what you need to know is what interest rate you need to qualify for to make the payment $400 a month. In the image below, you can see that if you didn’t have interest and just...

ONLINE STUDENT ADMISSION SYSTEM - Abstract - PHP

ONLINE STUDENT ADMISSION SYSTEM Abstract:- Today all the work at the time of admission of the students is done manually by ink and paper, which is very slow and consuming much efforts and time. It is required to Design of a Computerized Automated Student Admission System, to speed up and make it easy to use system. Student admissions are a vital part of any university’s running because students are what keep a University alive. The student admission is one of the most important activities within a university as one cannot survive without students. A poor admissions system can mean fewer students being admitted into a university because of mistakes or an overly slow response time. The process begins with a potential student completing an application form through the Universities and Colleges Admissions Service, the first step for students is to apply directly to the university through a custom online form. This project’s aim is to automate the system, prechec...

EXCEL CELL REFERENCES

EXCEL CELL REFERENCES When we create a formula using one of Excels built-in functions we will be referring it to a cell or range of cells. An example of a single cell reference would be A1 . An example of a range of cells reference would be A1:A10 . For the first example we are referring to the content of cell A1 only, while in the second example we would be referring to the contents of cells A1, A2, A3, A4, A5, A6, A7, A8, A9, A10 . Using the reference A1:A10 is just a simple method that Excel will automatically recognize. If we use the reference A1:C5 we are telling Excel to refer to the contents of cells A1, A2, A3, A4, A5, B1, B2, B3, B4, B5, C1, C2, C3 C4, C5 . Relative and Absolute Cell References Relative In Excel there are two types of cell references, these are Relative and Absolute . We will first look at relative cell references. All the examples in the Cell References paragraph are what are known as relative cell references. E each cell on an Excel Works...

A Study on Privacy-Preserving Data Mining on the Web Content Based Internet Privacy

A Study on Privacy-Preserving Data Mining on the Web Content Based Internet Privacy S.Parthiban, sparthibansoft@gmail.com. Abstract Privacy-preserving data mining (PPDM) is one of the newest trends in privacy and security research. It is driven by one of the major policy issues of the information era - the right to privacy . This chapter describes the foundations for further research in PPDM on the Web. In particular, we describe the problems we face in defining what information is private in data mining. We then describe the basis of PPDM including the historical roots, a discussion on how privacy can be violated in data mining, and the definition of privacy preservation in data mining based on users' personal information and information concerning their collective activity. Subsequently, we introduce a taxonomy of the existing PPDM techniques and a discussion on how these te...

What is a template?

What is a template? A template is a document type that creates a copy of itself when you open it. In Microsoft Office Word 2007, a template can be a .dotx file, or it can be a .dotm file (a .dotm file type allows you to enable macros in the file). For example, a business plan is a common document that is written in Word. Instead of creating the structure of the business plan from scratch, you can use a template with predefined page layout, fonts, margins, and styles. All you have to do is open a template, and fill in the text and the information that is specific to your document. When you save the document as a .docx or .docm file you save your document separately from the template on which it is based. Templates are exactly like documents in that you can provide recommended sections or required text for others to use, as well as content controls such as a pre-defined drop-down list or a special logo. You can add protection to a section of a template, or you can apply a passwo...

Mail merge

Mail merge Mail merge can be used to create a set of documents, such as a form letter that is sent to many customers or a sheet of address labels. Each letter or label has the same kind of information, yet the content is unique. For example, in letters to customers, each letter can be personalized to address each customer by name. The unique information in each letter or label comes from entries in a data source. The mail merge process consists of the following steps: 1. Set up the main document . The main document contains the text and graphics that are the same for each version of the merged document. For example, the return address or salutation in a form letter. 2. Connect the document to a data source . A data source is a file that contains the information to be merged into a document. For example, the names and addresses of the recipients of a letter. 3. Refine the list of recipients or items ....
