![]() ![]() Architectural programming is part of the pre-design phase of the design process, and acquiring accurate data is vital to a project’s success. This data is collected from previous architectural projects, technological research, client goals and expectations, and building codes among other things. Programming in architecture requires a lot of writing and number-crunching. As it is, we select the simple design because it is significantly easier to implement and maintain, having no synchronization overhead.However, there’s a lot more that goes into creating an architectural program than just creating bubble diagrams to show connections and space adjacencies. This is a more complex applicationīecause the multiple sites now require synchronization and intraprocessor scheduling in order to coordinate their work, but, if bottlenecks show up in a prototype of the first-cut process distribution, this is a likely candidate for the second iteration Even with SQL, we could distribute editing, the hardware management functions, payment and change processing, and printing of the rental copy to the local pes. As it is currently, SQL does not support multilocation processing although it does support distribution of databases.Īn alternative process distribution is shown in Figure 12-23. If SQL does not support multilocation processing, ![]() If SQL supports multilocation processing, then the comment stands. Having said this, the allocation is constrained by the software environment. Is suboptimal in terms of benefits to be gained from using PCs. This allocation of work is a problem because it does not take advantage of PC intelligence and, therefore, The most simple form of ABC's process diagram shows the file server as the processor and the PCs and printers as terminal devices (see Figure 12-22). The Booch diagram or the message list can also be used to validate the accuracy andĬompleteness of processes allocated to processors, and of the data allocated to storage devices. If there are more than one disk drive in the configuration, a list of the classes, class/ objects, and objects is made near eachĭrive that will contain data used by the application.įinally, the diagram is compared to the message list to ensure that all messages are accommodated in the diagram and accurately depict communications between processes. ![]() Next, for each processor, draw the terminals, printers, disk drives, and other peripheral devices that are attached to it. The lines only have directional pointers to show one-way communication.įIGURE 12-22 First-Cut ABC Process Diagram Only one line per set of processors is drawn, since the details of messages are documented elsewhere. Whether or not the application processes communicate). Lines are drawn to show communications capabilities between the processes, not between the processors (i.e., the processors are assumed to be networked Individual processes are allocated to each processor. One shadow cube is drawn for each processor. In any case, the processes are listed in small print next to the processor in which they will operate. Information engineering and apply them to this decision. In the absence of guidelines from the methodology, we can borrow the distribution decision techniques from In a defense environment in which the application developers are working from specifications developed by government employees in another city. This is an artifact of the development of 00 Similarly, there are no guidelines for allocating processes to processors. The methodology assumes that hardware configuration decisions are not part of the SE task and that the hardware decisions are known.

It is crude because devices and processors are all treated as the same, the only immediate visual knowledge This diagram is a crude equivalent of a system flowchart used before process methods were developed. Shown as transparent cubes (see Figure 12-21). Processors are shown on the diagram as a shadowed cube devices are A device is any dumb device that is part of the hardware configuration supporting application work. That performs data, presentation (i.e., monitor display), or application work. There are two types of icons used in the diagram: processor and device.
