Visual Expert
Visual Expert is a static program analyzer, extracting design and technical information from software source code by reverse-engineering, used by programmers for software maintenance [1] , modernization[2] or optimization.
Features
- Code exploration: call graphs, CRUD matrix, cross-references, dependency graphs [3] [4].
- Software documentation: a documentation generator produces technical documentation [4] and low-level design descriptions[5].
- Code comparison: finds differences between several versions of the same code.
- Automated code review: calculates software metrics and source lines of code [6]. Finds unused objects and methods. Identifies duplicate objects. Controls naming conventions.
Usage
Visual Expert is used in several contexts:
- Change impact analysis: evaluating the consequences of a change in the code or in a database. Avoiding negative side effects when evolving a system.
- Program comprehension: helping programmers understand and maintain existing code, or modernize legacy systems. Transferring knowledge of the code, from one programmer to another.
- Software sizing: calculating the size of an application, or a piece of code, in order to estimate development efforts.
- Code review: auditing source code, in order to discover issues, such as dead code, code causing poor performances or violations of programming conventions.
Limitations
- As a static code analyzer, Visual Expert is limited to the programming languages supported by its code parsers - Oracle PL/SQL, SQL Server Transact-SQL, PowerBuilder.
- A preliminary reverse engineering is required, with a duration depending on the size of the code parsed. Users must wait for the parsing completion prior to using the features, or schedule it in advance.
- Visual Expert is based on a client/server architecture: the code analysis is running on a windows PC - preferably a server. The information extracted from the code is stored in a RDBMS, communicating with a client application installed on the programmer’s computer - no web client available. This implies that the code, the parsers, the RDBMS and the programmers’ computers are connected to the same LAN or VPN.
