Activity diagram for stock management system

About this activity diagram for the stock management

The UML activity diagram for the stock management system captures the flow of action of two levels of users, namely the admins and the users. This process starts with the login function after which the system assesses the role of the user.

For admin users, the workflows have two paths. They are to control stock levels and generate reports. Admins in the 'manage stock' section can modify the stock level. They can add new products, change existing records, or remove out-of-stock items. Consequently, the system can reliably provide current stock levels. The other branch allows reports to be produced by admins. These reports can show the available stock levels.

On the other hand, for ordinary users the UML activity diagram is divided into two cardinal activities, that is, stock checking and order placing. If users opt for stock, the system will respond. It will show them information about the stock of products. However, if users decide to place orders, the process goes on with the system accepting orders and making arrangements for the order. After this step, inventory status is revised to account for the goods that have been sold.

The process is also interspersed with conditions involving decisions, for instance, whether a product is out of stock. If a product is out of stock, the system will quickly inform the user. This will stop that order. The UML diagram makes certain that any order made is properly managed and captured in the system.

The process ends with a logout action. It closes the session for users and admins. The UML activity diagram clearly distinguishes between two types of activities. It separates back-end tasks from front-end tasks.
