what is upper case and lower case character?
g
unicode defines case folding through the three case-mapping properties of each character: upper case, lower case, and title case (in this context, "title case" relates to ligatures and digraphs encoded as mixed-case single characters, in which the first component is in upper case and the second component in lower case). these properties relate all characters in scripts with differing cases to the other case variants of the character.
letter case
another common way to distinguish case tools is the distinction between upper case and lower case. upper case tools support business and analysis modeling. they support traditional diagrammatic languages such as er diagrams, data flow diagram, structure charts, decision trees, decision tables, etc. lower case tools support development activities, such as physical design, debugging, construction, testing, component integration, maintenance, and reverse engineering. all other activities span the entire life-cycle and apply equally to upper and lower case.
