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-3

Formula Reference in Excel 2010

Cell References in Formulas

Most formulas you create include references to cells or ranges. These references enable your formulas to work dynamically with the data contained in those cells or ranges. For example, if your formula refers to cell C2 and you change the value contained in C2, the formula result reflects new value automatically. If you didn’t use references in your formulas, you would need to edit the formulas themselves in order to change the values used in the formulas.

When you use a cell (or range) reference in a formula, you can use three types of references − relative, absolute, and mixed references.

Relative Cell References

The row and column references can change when you copy the formula to another cell because the references are actually offsets from the current row and column. By default, Excel creates relative cell references in formulas.

Absolute Cell References

The row and column references do not change when you copy the formula because the reference is to an actual cell address. An absolute reference uses two dollar signs in its address: one for the column letter and one for the row number (for example, $A$5).

Mixed Cell References

Both the row or column reference is relative and the other is absolute. Only one of the address parts is absolute (for example, $A5 or A$5).
