Information System Architecture For AccountIT

Introduction

From the Use Case Diagram it is seen that the AccountIT system has two primary functions:

• Users - records the users who are to access AccountIT.
• Books - records the accounts, which are the core of the AccountIT system

Besides need for data stores due to above functional requirements, non-functional requirements also require two data stores. These are:

• Roles and Permissions - records what roles a user has and the associated AccountIT functionality the user has permissions to.
• Audit Trail - records what activity a user has performed at a given point in time.
