SDD for UUIS TEAM 2 2010

The UUIS consists of six functional modules supplemented by a presentation layer. The presentation layer is in charge of parsing through the data to be displayed and outputting the relevant information as described in the requirement specification, while the logic layer will be divided into six modules. The database layer consists of a 20-table database. An Apache 2.2 server will parse through code written in PHP 5 to generate browser-readable output. In addition, it is responsible for ensuring that large datasets are properly truncated (as requested by the user, where applicable), and that controls for navigating through truncated datasets are SDD for UUIS TEAM 2 2010 4 provided. When truncation occurs, the presentation layer will display controls to display the data (1) immediately preceding the current records, (2) immediately following the current records, (3) at a given position by pagination, (4) the first set of records and/or (5) the last set of records. The output from the UUIS will also contain Javascript code in order to perform client-side presentation of information, as well as allow preliminary validation of data entered by the user before it reaches the logic layer. All operations are hidden from the external viewer with a wrapper class. The user-accessible functions are distributed across six functional modules. One such module groups together the miscellaneous functions accessible by all users (login, logout, submit requests, search, etc.). All university management operations are grouped into another functional module. A third module relates to asset-related operations, while a fourth interfaces with review options (audits and reports). There is a separate module for managing database errors, and the remaining module concerns privileged operations related to requests. The functions accessible to all users are of necessity those where no background check of the user's privilege is necessary, but merely require
