Maintenance of Software
- Today, we have still the fact that over 70% of the software development effort is spent in testing and maintenance of software.
- Schedule and cost estimates of software are grossly inaccurate, software has still a poor quality and the productivity rate for software is increasing more slowly than the demand for software.
- Schneidewind points out that there exists a maintenance problem because: 70 - 80% percent of the existing software was produced prior to significant use of structured programming.
- It is difficult to determine whether a change in code will affect something, It is difficult to relate specific programming actions to specific code.
- The major problem in doing maintenance is that we cannot do maintenance on a system which is not designed for maintenance.
- Introducing Modula 3 Wyant G.
One of the principal goals for the Modula-3 language was to be simple and comprehensible, yet suitable for building large, robust, long-lived applications and systems The language design process was one of consolidation and not innovation; that is, the goal was to consolidate ideas from several different languages, ideas that had proven useful for building large sophisticated systems - History of software measurement Zuse H.
Measurement in science has a long tradition as described by Lemmerich /LEMM88/ While the measurement of length - the meter - was defined in 1889 /LEMM88/, p87, the measurement of temperature was more complicated The graduation of the distance of the fixpoints was introduced by Fahrenheit in 1714 and by Celsius in 1742 - The book of VMware Word B.
This book strives to be a complete how-to and reference guide for VMware Workstation Each chapter starts with a hands-on, step-by-step guide to getting one piece of the puzzle up and running Then the material shifts into reference-style documentation - Описание RSL 0
