In Pascal casing the first letter of each word in an identifier is capitalized, e.g., BackColor

In Camel casing only the first letter of the second, third, etc. word in a name is capitalized; for example, backColor.

The table below provides the casing for the most common types.
However beware of the following:

• Words in all UPPERCASE, like e.g. DICOM, are a subset of Pascal casing and are therefore in principle allowed.
• However try to limit this to often used and/or well-known acronyms, like DICOM, PACS, PII, ...
• Also try to limit usage of this to enum values, const and/or read-only fields, variables and namespaces, unless good reasons exist to do so elsewhere.
