In this milestone enough information was provided to be able to quantify some but not all annual benefits. But a long text field such as the client name would make a poor primary key for Client, consuming extra storage space, slowing down database operations, and probably requiring extra typing. Would allow technicians to see what other technicians had done. A classification of EquipmentComponent. This was drawn in Microsoft Visio. Primary keys are shown at the top of the list of attributes and marked with PK.
The system should allow technicians to view and edit software configuration information in the field. Whether or not they identify the optional entities will depend on how they interpret the user requirements and on their experience level with database normalization. Consumes a great amount of receptionist’s time. The diagram below includes foreign keys, assuming implementation in a relational database. A piece of Equipment is made up of one or more EquipmentComponents that either have in the past or are now installed.
Foreign keys are marked with FK and a number. If system is not always online then need to replicate data between master database and copies.
Evaluate their thought processes. Consumes a great amount of receptionist’s time. Students should be able to defend their answers with specific statements from the case study milestine. It is possible they might have identified different ones and have stated completely different values for each of the cells.
Causes and Effects Receptionist takes calls and route to technicians with phone transfer or e-mail. The real problem with adding purchase orders to CTTS is that it opens the door on accounting functions. Vendor would be a parent table to PurchaseOrder, contributing milestohe VendorID in a non-identifying relationship. Create a searchable database of configuration information. If use barcode scanning, would have to make sure barcode was on every piece of equipment.
The service request part of the system should have adequate security. Some, but not all, of the configuration records could be associated with a piece of Equipment. Logon Multiple Values of Information i.
Three-ring binder is difficult to keep up-to-date because word processing documents cannot be updated in the field. The proposal has an opportunity to provide better service to users along with reduced costs and better information to both IT personnel and management. The proposed system could provide a customer history that would allow for better service.
If use barcode scanning, cths have to change inventory check-in process. This could be the primary key. In your xtudy discussion you might point out that functional requirements show up in the context model, while generally non-functional requirements do not studh up in the context model other than to specify the actors that can do send or receive certain information.
Requirement The system should allow technicians to view and edit hardware component information in the field. But a long text field such as the client name would make a poor primary key for Client, consuming extra storage space, slowing down database operations, and probably requiring extra typing. This, of course, is DFD style. Pay careful attention to the classification. One approach could be the use of barcode scanning.
This would also be a system-generated number. Prepared by Gary B.
This was drawn in Csse Visio. The sample RSS provided here represents a general description. The Data Flow Model template found in the Software category can produce one that is like the sample except that the square Interface symbol must be used instead of the Actor symbol.
Component information will include purchase date to track warranty periods. The proposed system could allow clients to enter service requests online, saving receptionist time plus providing more efficiency.
Techs should be able to mark a service request as resolved The system should be able to mark as service request as resolved if nothing more is heard from the client after the passage of a set amount of time Classification Functional Functional Non-functional Non-functional Functional Non-functional Non-functional Non-functional Functional Functional Non-functional Functional Non-functional Functional Functional Prepared by Gary B.
Mklestone Definition Solution Page: Each piece of Equipment is owned by a particular Client. Configuration information will be very flexible to handle all the kinds of information that needs to be tracked. System Constraint Internet application must have adequate security.
