What is import/export of data? Why is it necessary to refresh the import/export data inMicrosoft Excel and Microsoft Access on a timely basis?

What will be an ideal response?

Import/export is the process of transferring data from one computer system to another.
In almost all cases, including Microsoft Excel and Microsoft Access, import/export does not
maintain an active connection to the source of the data. If users subsequently change the Access
data, the imported data in Excel will be out of date until the users reimport it. As the imported
data can become outdated, users should develop procedures (either manual or automated) to
ensure that data are refreshed on a timely basis.
