Headline
A non-monadic implementation of the Logging feature in F# for the Technology:.NET Framework
Characteristics
This first step in logging salary changes is implemented through a straightforward family of functions in a way that salary changes are passed into and out of functions through tuples. This code is quite voluminous and can be improved and shortened by using monads.
Illustration
Salary changes are kept through the following log data:
Invalid Language supplied
A log resulting of a salary cut from the sample company:
Invalid Language supplied
The median can be computed for a given log as follows:
Invalid Language supplied
The sample log resolves to the following median:

Feature:Cut is implemented in a logging-enabling way as follows:

Relationships
See Contribution:fsharpRecords for a implementation of Feature:Cut without logging.
Architecture
The contribution consists of five modules: "Data.fs" which contains the definition of the used classes; "Sample.fs" which creates a sample instance of a company; "Log.fs" which contains the log datastructure as well as the functions log2deltas, log2mean and log2median. "Cut.fs" which contains the cut functions (with logs) for employees, departments and a company. "Main.fs" which basically creates a sample company through "buildCompany" of "Sample.fs" and executes cut printing the results as well as the log;
