Some Words on Naming Conventions
When you're developing applications there are two real dangers in poor naming conventions.

Firstly, you may hit on a reserved term. Take where for example. If you were to write a query that looked something like this 
sql = "select * from cities where" & where &"= 'New York' "

You would get an error because where is a reserved term. There are many combinations that are reserved and depending on a multitude of factors you could be using them directly like the example above or in the course of url encoding the name of a variable like reg could be converted to &reg which will produce the registered trademark symbol ®. 

To avoid this type of problem a list of reserved terms could be posted here with a big DO NOT USE THESE OR ELSE banner blazing at the top and with every new version of this or that it would have to be revised. To completely avoid this kind of problem what is encouraged at is the following:

Any user inputted value starts with u_
Following this convention the example above would look like this
sql = "select * from cities where" & u_where &"= 'New York' "
and would work without a hitch.

The example of where a variable named reg would not run into the same problems if it were named u_reg. Utilizing u_ as the signifier of any user inputted values aids in more ways than one. During debugging finding variables is made much easier.

But what about variables that are generated off of user inputted values? Simple we encourage the use of g_ as the signifier for any variable that is a created/modified version of the user inputted value. This method will no prevent error if you db has a field on it named after a reserved term, for example where (location might be a better choice)

The second danger is when the varibles names themselves have no real connection to the data they may hold. If you have a list of possible years for a user to input don't name the variable flood or something that has no real meaning. Use year or as discussed above u_year.
