Together with the previous chapter, this chapter encompasses the most common operations that IDA users will ever need to perform. Through the use of database modifications, you will combine your own knowledge with the knowledge imparted by IDA during its analysis phase to produce much more useful databases. As with source code, the effective use of names, assignment of datatypes, and detailed comments will not only assist you in remembering what you have analyzed but will also greatly assist others who may be required to make use of your work. In the next chapter we continue to drill into IDA’s capabilities by taking a look at how to deal with more complex data structures, such as those represented by the C struct, and go on to examine some of the low-level details of compiled C++.
