....can be found. Vertical abstractions are produced automatically by omitting internal 149 method calls. 8. 10 Related work Several tools and environments supporting reverse engineering and architecture recovery rely on static analysis of the software, for example, Rigi [74] Bookshelf [34] CIAO [15], and Sniff [115] In addition, many tools supporting forward engineering of object oriented software are also able to extract class diagrams for existing software. We consider here tools, environments, and methods that 1. support dynamic reverse engineering of object oriented software systems ....

....into the originating text. Jupiter also permits the storage and querying of unparsed material such as comments or programmer attached annotations. ACACIA [5] uses ASCII files to store data. The cql [19] query language is used for access and serves as an interface between the database and the Ciao [4] graphical repository navigator. ACACIA requires that extracted data match a predefined entity relationship based model, specifically designed for C . Jupiter is more general in applicability being language independent. Instead of focusing on the data representation, it is possible to design a ....

....active system to model. That is, dynamic analysis is performed on a running system, while, static analysis is performed on system artifacts (e.g. source code) In the static analysis field, the Ciao system, created by Chen, et al. provides a framework for performing static analysis of source code [3]. This fundamental technology has facilitated the creation of many static program analysis tools, such as our own Bunch tool [11] Our Form framework aspires to fill a similar role in the dynamic analysis field to the role played by Ciao in the static analysis field. Our discussion will now ....

....system understanding, i.e. at assisting the re engineer in understanding what components (modules, databases, screens, copybooks, the system consists of, and how these are related to each other. Figure 1 shows the extractor query viewer approach used in most reverse engineering tool sets [37, 16, 20]. It can be used to extract all sorts of facts from the legacy sources into a database. This database, in turn, can be queried, and relations of interest can be visualized. In the extractor phase, syntactic analysis will help to unravel the structure of the legacy code. This requires the ....
