An example of the use of triggers, agents and alerts is a forecast accuracy monitoring application. When each week's actual sales are updated to the data warehouse, the system automatically calculates the mean absolute percent error between forecasted and actual results over the previous six weeks for every product. The mean absolute percent error is a simple way of representing forecast error over time. An alert is sent to each marketing manager responsible for the product forecast if a threshold for the mean absolute percent error calculation is exceeded. Building secure applications for the Intranet requires a well thought out security strategy as well as the appropriate application architecture.
Most Web applications provide all users with the same access permissions.
The information available is either of low or no level of confidentiality. Examples include human resource forms for insurance, vacation requests, and company phone lists as well as market information. Business users require a system that maps them to their server account by verifying user names and passwords. When server applications are run, they will have access to their files secured by user, group and world permission levels. The same issue exists with database security.
