Financial accounting, especially its bookkeeping component, operates more or less like a semi$-$automated machine. Its activities include capturing, classifying, recording, analysing and reporting the financial outcomes of financial transactions and events. Using a particular transaction $($or a category of transaction, for example a sales transaction$)$ explain how these activities are performed. Pay special attention to:

a$)$ How the transaction is captured to the transaction processing system and the particular document needed to be produced to prove its occurrence.

b$)$ How it is classified and aggregated with other similar transactions.

c$)$ How it is recorded in the accounting system using the double entry rules.

d$)$ How it is summarised and reported in the financial statements
