SOFTWARE OVERVIEW <br />Incorporating flexibility, versatility, and functionality in the Point Flow Analysis Software was an <br />underlying objective throughout development. The resulting software is a bi- modular program <br />design in which each module is autonomous. This allows independent utilization of each module, <br />and additional flexibility when adapting the point flow software to complement <br />pre - existing software. The first of the two modules performs the function of manipulating the raw <br />input data (historical data) to calculate river gains and point flows, while the second module <br />allows users to access and display the resulting information in a user friendly environment. This <br />section introduces users to 1) the overall framework of each module, 2) the module components, <br />and 3) the manner by which information is stored and transferred between modules. <br />The two modules, hereafter referred to as the 'Point Flow Module' (PFM) and the 'Querying and <br />Charting Module' (Q &CM), are displayed in Figure 3. The division between the PFM and the <br />Q &CM is denoted by the vertically arrowed lines on the left side of Figure 3. As noted above, <br />each module operates independently with the only connection being through the two tables <br />created by the PFM and through the 'Control Table' which is accessed by both modules. <br />' User's Interface <br />I * Point Flow Period F <br />— * Input/Output File Names— i <br />w. <br />User's Interface <br />i — * Querying Mgus — — — i <br />� *Input File Names i <br />Point Flow Software <br />(Microsoft FoxPro) <br />Subrewh'Gains' River'Flows' <br />Table Table <br />Qumying & Charting <br />Software <br />(Mierosoft Excel) <br />Charts & Summary Tables <br />Monitor Printer <br />control <br />Tablonte <br />Historical Data <br />Table N <br />Historical Data <br />Table N +1 <br />Figure 3 Schematic of Point Flow Module and Querying and Charting Module. <br />11 ptflguid.wpd <br />
