Did you know that for software developers the speech "business" (as in "business requirements," "business layer," or "business specs") has a purpose extremely distinguishable than its balanced routine connotation?

For a computer code engineer, a "business layer" has zilch to do next to selling commodities and employment and fashioning wealth or running a tangible business; but everything to do beside the way an "3-tier client-server architecture" is structured.

More specifically, a "business layer" is the intermediator stratum linking the "client" flat solid (or, the "front-end" or the Graphic User Interface (GUI), that is, any you see and act near on a machine surface) and the "back-end" or the "server" section.

When you chink a linkage on a web page, for example, you are at the "front end" and you are the "client."

The "business layer," or the "traffic cop" in between, takes that sound tell and sends it to the "back end."

If, for example, what you have requested for is a web page, the concern flat solid tells the web waiter to brainstorm that folio.

And when the page is found, once again the firm lode delivers it to your screen.

If what you have clicked on the peak is a fixing for finding the terms of a copy (for information), the commercial deposit sends the "question" to the information in the hindermost end. The fee digit obtained from the DB (database) server is transmitted fund to your peak after passing through with the "business covering."

A "business" veil is named such because the rules according to which it the stage "traffic cop" to the ingoing and effluent signals ebb and flow from one business organization to different. A creating from raw materials company, for example, would entail a opposite set of interactions concerning its front and rear ends than (let's say) a tooth doctor or a carnation sales outlet.

That's why "business specs" or "business requirements" also change from one company to different because they all involve their inputs (from the "client" covering) move otherwise near their web-servers or data-base servers (at the "server" sheet).
