NAMING CONVENTIONS :
STYLE :
A consistent naming convention can also make Cde easier to read. There are essentially two forms of naming conventions in C#.
The first is pascal casing, where the first letter of each word in a name is capitalized, such as HelloWorld, DotProduct, or AmortizationSchedule. This is normally used in all instances except for parameters and private fields of classes.
In the case of private class fields and method parameters, use camel casing. This is where the first letter of the first word is lowercase and subsequent words are capitalized, such as bookTitle, employeeName, or totalCompensation.
This naming standard also helps to avoid creating bugs caused by type confusion and makes it easier to find these bugs later.

General Rules to Follow :
- Don't Use complicated, long names for tables or other database objects. keep it simple
- Prefer to use 'Mixed case' names instead of using underscores to separate two words of a name. However, when you use mixed case names, your developers should be consistent with case through out their code, on case sensitive SQL Servers
- Use underscores only between the prefix/suffix and the actual object name. That is, never break the name of an object with underscores
- Prefer not to use spaces within the name of database objects, as spaces confuse front-end data access tools and applications. If you must use spaces within the name of a database object, make sure you surround the name with square brackets (in Microsoft SQL Server) as shown here: [Order Details]
- Make sure not using any reserved words for naming my database objects, as that can lead to some unpredictable situations. To get a list of reserved words for Microsoft SQL Server, search Books Online for 'Reserved keywords'
