Sorry guys ive been busy studying, alright here are the sections:
Davis - Incremental Compilation: The aim of incremental compilation is to reduce the time spent in recompiling source code. Large software products involving a large team of developers can take a significant time to compile. Incremental compilers aim to reduce the translation time by only recompiling those parts of the code that have changed since the last compile took place.
Fowler - Incremetal Compilation: When a program is run using incremental compilation the commonly executed routines are translated into machine code and stored. The program itself is translated using an interpreter, but when these compiled routines are needed they are run from the stored code rather than being re-translated each time the code is reached. This speeds up the process of running the interpreted prgogram while keeping the advantages of and interpreter.
Fowler - Operational considerations: The purpose of a new computer system is to meet the needs of the organisation. In meeting these needs, the new system will have some form of impact on the organisation, from management through to the direct users.
Davis - Operational considerations: revolve around whether the software developer has the expertise and resources to complete the task.
I called hsc advice line and they said operational consideration must be answered to the context of the question, but if they ask a question from one book, then how would I know if it was the other (if i never had the other).
And also with incremental compilation, the lady said that they can either be an interpreter and/or a compiler.
