IMPORT & EXPORT

 

Import means to bring data into the application and export means to send data from the application.

Data integration means that the data can be shared between many applications.

There are two main methods of data integration

 

1.         STATIC

The source application (where the data comes from) does not maintain a link with the target application (where the data is going to). An example of this is when we have used the shortcut keys ALT+PRINT SCREEN to copy what is on the screen into clipboard. We can change what is on the screen but clipboard stays the same. It does not get updated.

This is what my screen looked like as I was typing this page

 

2.                  DYNAMIC

 

The source application (where the data comes from) does maintain a link with the target application (where the data is going to). An example of this is in fully integrated packages of wordprocessor, database, spreadsheet & communications (Works, ClarisWorks, Office 97). If a wordprocessor document is linked with a spreadsheet, any change in the spreadsheet will be automatically updated in the wordprocessor document. This could also include any chart that has been imported into the wordprocessor document.

The table and chart are linked to the speadsheet  application
