In the Excel program, a data point is a point of reference. They are used to highlight or mark specific sections or areas. To create a data point you need to click on the first section you wish highlighted, click the second point of reference then label it.
Excel 2007 does not have this capability. Excel 2003 can do this as described in the related link. The idea is to draw your graph, then overlay a non-related point on the graph. When you drag the non-related point to the location on the graph where you want to identify a data point, you will see the underlying cell reference change to the location of your selected data point.
A worksheet cell with a numeric value is called a data point.
You can copy data from Access and paste it directly into Excel. From a table or query, data can be selected and then copied and pasted into Excel. In that case, data changing in the original Access file will not change data in the Excel file. To do that there must be a link between the data. You can also import data from Access into Excel and from Excel into Access, again maintaining a link to the source if you want.
It is data coming from another source, such as a database. It is external to Excel, but being used by Excel.
To determine the equivalence point on a titration curve in Excel, you can identify the point where the slope of the curve is steepest. This is where the concentration of the titrant is equal to the concentration of the analyte being titrated. You can use Excel to plot the titration data and calculate the derivative of the curve to find the point of maximum slope, which corresponds to the equivalence point.

Excel files will have data in them, so in that way they are storing data. Excel is not a disk or USB key or other such data storage devices. It is software, not hardware.
A chart is a visual representation of data in Excel.
You need to set up a web query. On the Data tab, there is a "From Web" option. You'll need to know details of where you are getting the data in order to be able to do this. So beyond that basic start point, it will depend on the data you are getting and where you are getting it from in order to bring it into Excel.
Without data, there is not much Excel can do. Formulas will have no data to work on. Charts will not show anything. Data is very important to Excel. There are things you can do without it, like draw shapes, but Excel is designed to do things with data, so you need to have some.
You can interrogate data in Excel 2007 by using the filter and sort options in Excel. This re-organizes the data in a way that makes it easy to analyze and evaluate the data.
