DefinitionCoding (コーディング) is the work of writing out the processing steps fixed in detailed design according to the grammar of a programming language, producing source code; it is also called programming (プログラミング).
ExplanationThe work covers turning the processing flow and data handling in the detailed design document into instructions line by line, and checking the written steps for errors. A team agrees in advance on coding conventions (コーディング規約) for naming, indentation and the like, so that code stays easy to read no matter who wrote it. Readable code cuts the effort of later reviews and maintenance.
AnalogyIt is like assembling furniture while following the instruction sheet. The dimensions and steps on paper are turned, one by one, into real parts.
Memory hook"Code" means a set of symbols: think of turning human ideas into symbols a machine can read.
