| + | One simple example to described the importance of planning in advance the structure of the rules within a group or the groups themselves is in the scope of the configuration of a computer the calculation of the memory modules required. One way to accommodate this situation is to let the user input the requested amount of memory he would like to have configured in his machine. | ||
| + | |||
| + | The first rule will determine the number of 1 GB modules required to suit his needs. For example the input is 4 GB and the result is 4 modules of 1 GB each. The situation would be more complicated if the user had chosen 8 GB and that the machine could only hold 4 modules in total. This means that the model requires a second rule to check the number of 1 GB module against the number of slots available. In the example of a input equal to 8, the resulting number of modules is 8. The second rule could then take this value and modify the result to 2 GB modules thus making it possible to be installed on the machine. | ||
| + | |||
| + | Because in this situation the second needs to have the result of the first one available in order to use it has an input it is necessary that second be placed in another group of rules which should be executed after the one containing the first rule. | ||
