Waste collection is often designated to an organization that provides professional waste management services. A typical waste collection process involves (1) back officers, who operate a central system to create calendar, coordinate front collectors and janitors ,(2) collectors, who drive different types of vehicles and (3) janitors who manually collect garbage from Major Collecting Points (MCPs). Calendar and tasks were assigned among teams of janitors and coordinated by back officers. These assignments are often arranged in a weekly basic. Back officers also plan which vehicles to use and their routes. This planning activity happens every month. Everyday, the back officers sent messages with information about collecting route and time to collectors and janitors. Janitors use trollers (see Figure 1b) to collect garbage in their assigned areas and deliver to the MCPs. Collectors will pick up garbage from all janitors at an MCP. One collector drives only one vehicle during his working shift. The collector will drive through several MCPs with a predetermined route by back officers.

A user story is a short, simple description of a feature told from the perspective of the person who desires the new capability, usually a user or customer of the system. User stories typically follow a simple template: As a < type of user >,1 want < some goal > so that < some reason > User stories were historically written on index cards or sticky notes, stored in a shoe box, and arranged on walls or tables to facilitate planning and discussion. Nowadays, they might just as easily be stored in a Jira issue User stories are designed to strongly shift the focus from writing about features to discussing them. In fact, these discussions are more important than whatever text is BK written. 61 TP.HCM",

For example, a landline phone switching system responds to events such as receiver off hook' by generating a dial tone. Event-driven modeling shows s how a system responds to external and internal events.

The system is structured into three logical components that interact with each other. The Model component manages the system data and associated operations on that data. The View component defines and manages how the data is presented to the user. The Controller component manages user interaction (e.g., key presses, mouse clicks, etc.) and passes these interactions to the View and the Model. Example The next slide shows the architecture of a web-based application system organized using the MVC pattern. When used Used when there are multiple ways to view and interact with data. Also used when the future requirements for interaction and presentation of data are unknown. Advantages Allows the data to change independently of its representation and vice versa. Supports presentation of the same data in different ways with changes made in one representation shown in all of them.

A layer provides services to the layer above it so the lowest-level layers represent core services that are likely to be used throughout the system. See Figure 6.6. Example A layered model of a system for sharing copyright documents held in different libraries When used Used when building new facilities on top of existing systems; when the development is spread across several teams with each team responsibility for a layer of functionality; when there is a requirement for multi-level security. Advantages Allows replacement of entire layers so long as the interface is maintained. Redundant facilities (e.g., authentication) can be provided in each layer to increase the dependability of the system. Disadvantages In practice, providing a clean separation between layers is often difficult and a high-level layer may have to interact directly with lower- level layers rather than through the layer immediately below it. Performance can be a problem because of multiple levels of interpretation of a service request as it is processed at each layer. BK Sep 2019 CHAPTER 6. SOFTWARE ARCHITECTURE DESIGN 24 P.HCM",

Components do not interact directly, only through the repository. Example The next is an example of an IDE where the components use a repository of system design information. Each software tool generates information which is then available for use by other tools. When used You should use this pattern when you have a system in which large volumes of information are generated that has to be stored for a long time. You may also use it in data-driven systems where the inclusion of data in the repository triggers an action or tool. Advantages Components can be independent-they do not need to know of the existence of other components. Changes made by one component can be propagated to all components. All data can be managed consistently (e.g., backups done at the same time) as it is all in one place. Disadvantages The repository is a single point of failure so problems in the repository affect the whole system. May be inefficiencies in organizing all communication through the repository.

Clients s are users of these services and access  servers  to make use of them. Example Figure in the next slide is an example of a film and video/DVD library organized as a client-server system. When used Used when data in a shared database has to be accessed from a range of locations. Because servers can be replicated, may also be used when the load on a system is variable. Advantages The principal advantage of this model is that servers l be 1 can distributed across a network. General functionality (e.g., a printing service) can be available to all clients and does not need to be implemented by all services. Disadvantages Each service is a single point of failure so susceptible to denial of service attacks or server failure. Performance may be unpredictable because it depends on the network as well as the system. May be management problems if servers are owned by different organizations. BK Sep 2019 CHAPTER 6.

    "text": "THE PIPE AND FILTER PATTERN Name Pipe and filter Description The processing of the data in a system is organized so that each processing component (filter) is discrete and carries out one type of data transformation. The data flows (as in a pipe) from one component to another for processing. Example Figure in the next slide is an example of a pipe and filter system used for processing invoices. When used Commonly used in data processing applications (both batch- and transaction-based) where inputs are processed in separate stages to generate related outputs Advantages Easy to understand and supports transformation reuse. Workflow style matches the structure of many business processes. Evolution l by adding transformations is straightforward. Can be implemented as either a sequential or concurrent system. Disadvantages The format for data transfer has to be agreed l upon between communicating transformations. Each transformation must parse its input and unparse its output to the agreed form. This increases system overhead and may mean that it is impossible e to reuse functional transformations that use incompatible data structures. BK Sep 2019 CHAPTER 6.
