Software architecture sad

Examples from projects include:. In some cases, if the customer has the responsibility for a specific security area or mitigation for example, DoS attack mitigation but doesn't have the solution in place, this should be tracked as a project risk.

The S olution Architecture Definition document should be treated as an evolving document throughout the project. It is important to keep the content up to date especially when the projects span over multiple releases. You are entering a site that is not hosted by SAP.

Commerce solutions. Article Tags. Last Updated: Apr 30, Copy Article URL. Objective and Contents The Software Architecture Definition SAD document describes the subsystems and components of the solution by presenting a number of architectural views. Assumptions and Constraints Section 4 documents significant constraints, assumptions and requirements that influence the architecture of the solution.

Context View Section 5 gives a high-level representation of the system's main components, the different user types, and interactions with external entities. Project View Section 6 shows how key functionality relevant to the solution architecture maps to releases and milestones. Relevant NFR spreadsheet content: Page response time should not exceed 1 second. Relevant SAD content in this section: In order to achieve high performing page response times, the solution will use caching type X, Y and Z which are configured as follows.

Examples from projects include: The customer is responsible for the configuration of the public internet facing web server in the live production environment. The customer is responsible for obtaining SSL certificate, renewing and managing them. The project team and solution don't offer any protection from Denial of Service attacks. Conclusion The S olution Architecture Definition document should be treated as an evolving document throughout the project.

If the system is menu-driven, a description of all menus and their components should be provided. Describes the command-line interface if present. For each command, a description of all arguments and example values and invocations should be provided. Describes the application programming interface, if present.

Foreach public interface function, the name, arguments, return values, examples of invocation, and interactions with other functions should be provided. If this package is a library, the functions that the library provides should be described here together with the parameters. A high level description from a software point of view of the hardware interface if one exists.

This section can refer to an ICD Interface Control Document that will contain the detail description of this interface.

A high level description from a software point of view of the software interface if one exists. Describe the architecturally significant logical structure of the system.

Think of decomposition in terms of layers and subsystems. Also describe the way in which, in view of the decomposition, Use Cases are technically translated into Use Case Realizations. This is a very common design pattern used when developing systems that consist of many components across multiple levels of abstraction as in ERAS case.

There are some key requirements and system constraints that have a significant bearing on the architecture. They are:. A description of the use-case view of the software architecture. These use cases are initiated by the student, professor, or the registrar actors. In addition, interaction with external actors; Course Catalog and Billing System occur.

Brief Description:This use case allows a Registrar to close the registration process. Course offerings that do not have enough students are cancelled.

Course offerings must have a minimum of three students in them. The billing system is notified for each student in each course offering that is not cancelled, so the student can be billed for the course offering. The main actor of this use case is the Registrar. The Billing System is an actor involved within this use case. The actors starting this use case are Student, Professor, and Registrar. Brief Description:This use case allows the registrar to maintain professor information in the registration system.

This includes adding, modifying, and deleting professors from the system. The actor of this use case is the Registrar. The actor starting this use case is the Professor.

The Course Catalog System is an actor within the use case. Brief Description:This use case allows a student to register for courses in the current semester.

The Billing System is notified of all registration updates. The Course Catalog provides a list of all the course offerings for the current semester. The main actor of this use case is the student.

The student is the actor of this use case. Brief Description:This use case allows a professor to submit student grades for one or more classes completed in the previous semester. The actor in this use case is the Professor. Brief Description:This use case allows the registrar to maintain student information in the registration system. This includes adding, modifying, and deleting students from the system. The actor for this use case is the Registrar. A description of the logical view of the architecture.

Describes the most important classes, their organization in service packages and subsystems, and the organization of these subsystems into layers. Also describes the most important use-case realizations, for example, the dynamic aspects of the architecture. Class diagrams may be included to illustrate the relationships between architecturally significant classes, subsystems, packages and layers.

The logical view of the course registration system is comprised of the 3 main packages: User Interface, Business Services, and Business Objects.

The User Interface Package contains classes for each of the forms that the actors use to communicate with the System.
