Proposed Solution <br />5. System Overview <br />(5) provide msystem overview, including mmoverview of the technical architecture and the proposed hardware environment; <br />There are nohardware requirements for our Cloud applications. All application functionality isthrough a <br />modern web browser. Architecturally, |nfnr Public Sector (IPS) ooOwena solution is made up of three <br />layers: the data layer, the business layer, and the presentation layer. The purpose of the three -layer <br />architecture |stomake |PS aoopen mmpossible for configuration and extension. All data iastored inthe <br />data layer and kept separate from the system's business logic, which makes up the business layer, The <br />user interface is kept separate from both data and business logic in the presentation layer, <br />Data Layer: The main component of the data layer ieanOracle mSQL Server database that stores the <br />agency's data (which aaoSaaSoffering, the City does not have toworry about).What isimportant to <br />understand isthe data structure, which exists independently nfthe specific database application. Each <br />distribution of |PS |nn|udao afu|| description of the data structure, which the |PS Installer uses as a <br />blueprint tpbuild the actual database during the installation process. <br />Business Layer: The purpose nfthe |PSbusiness layer iobzmake the system's full range nfbusiness <br />logic accessible byisolating it from both the database and the user interface, The business layer begins <br />with an abstraction of the data structure, with a business object corresponding to each table and a <br />business object property for each column. Any additional logic that is needed can then be added directly <br />tothe business objects. <br />Presentation Layer: The presentation layer isthe simplest ofthe three layers —it iathe user interface. <br />Infor Public Sector is a browser -based application, so there is no separate client application toinstall on <br />the users' machines. Instead, users access the system by opening a web browser and logging into the <br />|nforPub||o Sector site over the network. On the oem/e[ the interface consists of standard Web files such <br />as .html, empx. .rss' and image files, as well a set ofopp|etm that contain code that the interface uses to <br />communicate with the business ob|ectn. During system setup the Installer also creates o site for |m[mr <br />Public Sector in Internet Information Services (IIS). <br />IoNed <br />oJect <br />Table <br />6.Software Description <br />(6) describe each software module that is being proposed; <br />Infor Public Secto�r Suite: Aaonapdication s-focmsedcompany, |nforainterest |naligned wi(h <br />customers; our goal is to mad|md|y simplify integration, minimize infrastructure ioveshnerKe, and think <br />:I ' i ,/v. xxx �m, o.00/ 3-2 <br />
