Microsoft Access MS Access Basics Tips and Trick-7

Adding Data An Access database is not a file in the same sense as a Microsoft Office Word document or a Microsoft Office PowerPoint are. Instead, an Access database is a collection of objects like tables, forms, reports, queries etc. that must work together for a database to function properly. We have now created two tables with all of the fields and field properties necessary in our database. To view, change, insert, or delete data in a table within Access, you can use the table’s Datasheet View. A datasheet is a simple way to look at your data in rows and columns without any special formatting. Whenever you create a new web table, Access automatically creates two views that you can start using immediately for data entry. A table open in Datasheet View resembles an Excel worksheet, and you can type or paste data into one or more fields. You do not need to explicitly save your data. Access commits your changes to the table when you move the cursor to a new field in the same row, or whe...

Microsoft Excel-office WORKING WITH FORMULA Tips and Tricks-4

Using Functions in Excel 2010

Functions in Formula

Many formulas you create use available worksheet functions. These functions enable you to greatly enhance the power of your formulas and perform calculations that are difficult if you use only the operators. For example, you can use the LOG or SIN function to calculate the Logarithm or Sin ratio. You can’t do this complicated calculation by using the mathematical operators alone.

Using Functions

When you type = sign and then type any alphabet you will see the searched functions as below.

Suppose you need to determine the largest value in a range. A formula can’t tell you the answer without using a function. We will use formula that uses the MAX function to return the largest value in the range B3:B8 as =MAX(A1:D100).

Another example of functions. Suppose you want to find if the cell of month is greater than 1900 then we can give Bonus to Sales representative. The we can achieve it with writing formula with IF functions as=IF(B9>1900,"Yes","No")

Function Arguments

In the above examples, you may have noticed that all the functions used parentheses. The information inside the parentheses is the list of arguments.

Functions vary in how they use arguments. Depending on what it has to do, a function may use.

  • No arguments − Examples − Now(), Date(), etc.

  • One argument − UPPER(), LOWER(), etc.

  • A fixed number of arguments − IF(), MAX(), MIN(), AVERGAGE(), etc.

  • Infinite number of arguments

  • Optional arguments
