5.6 Rational Asset Analyzer and source metrics After Rational Asset Analyzer has scanned the source code, it loads the metadata about all source artifacts into the repository or database (DB2). On completion, Rational Asset Analyzer returns you to the home page for subsequent analysis work. Figure 5-21 shows the common assets, which are listed on the left side of the page and show your entire collected inventory. Notice the two pie charts that present a breakdown of all of the various file types that were inventoried. For example, Figure 5-22 illustrates mousing over a pie chart, showing that 2.1% of the scanned code is either a basic mapping support (BMS) map or a Message Format Service (MFS) map. You can move the mouse pointer over the pie charts to view a high-level breakdown of the types of assets that you have scanned into your repository and the technologies and languages that underlay the assets (COBOL, PL/I, CA-Easytrieve, Assembler, and so forth). This high-level view is interesting, but the metrics that are captured during the analysis scan are of much greater use.
