Vig: You might need to read up on 'normalizing' a database. It is a procedure where you isolate recurring entries into their own table. Thus, if you try to have a database containing a list of computers and their installed softwares, you'd create a total of three tables. Table 1 contains ComputerID and ComputerName, Table 2 contains SoftwareID and SoftwareName, Table 3 will be a look-up table containing ComputerID and SoftwareID with one-to-many relationships for table 1 and and 2 to table 3, respectively.
