Introduction

Design I am going to do 3 databases for which in all will contain information of its purpose, the databases will be joined together through a primary key, which will be unique and identify each, joining them all together. . In one will be information on all the houses the real estate agent "elite" own and in another will be information on all the current customers they are dealing with at the moment allowing space to enter new customers as well, and in the other will be a database of the houses what customers have visited. Below is a list of field names I will use for my first database.

Some examples of queries that will be asked include: > How many visits took place to 5 Aston avenue on may 5th 2000? This problem could be rectified easily by using my database and going to queries, then the user could type in the necessary information example; Like 5 and Like Ashton avenue etc. > What houses has Fred Bradley visited? Again this problem could easily be solved using my database and going to query wizard filling in the necessary information. For the first query above the information entered will look something like this My data will be outputted in a number of ways the information will be mainly all screen based and only needed for extensions onto other documents. ...read more.

Conclusion

A file format is the way in which information is stored in a file so that a program can open and save the file. A file's format is indicated by a three-letter extension after the file name. For example, when you save a new document in Microsoft Word 2000, Word by default stores it in Word 2000 format with a .doc file extension. If you want to convert a document to a different format so that you or someone else can open it in another program or in an earlier version of Word, you can select that file format when you save the document this is the same principle as for access except using the different unique file format of .mdb. All my files will be double backed up onto two master discs and be kept safely with other important files they will be updated regularly making sure to include all necessary information. All data will be kept on each of Elite the real estate's company computers for access by all employee's at any time when required. If a fault does occur in the system the master discs should be bought into availability to re-boot the system. ...read more.
