2. LDAP Servers - Netscape Directory Server, Microsoft Active Directory (AD), Novell Directory Services (NDS), Sun Directory Services (SDS), ucent's Internet Directory Server (IDS)
3. LDAP uses a client server model, with clients sending LDAP request over TCP/IP to the server.

5. Designed to be read data more than written, such as No transactions or rollback.

ISNULL VS COALESCE

For example Production.Product table records

Class	Color	ProductNumber
cl1	Null	Null
cl2	Null	Null
Null	co3	Null
Null	co4	Null
Null	Null	pn5
cl6	co6	Null
cl7	co7	pn7

Debug Directive

If the code is only for development environment not in the live or release environment use Debug Directive or Conditional attribute For exmple, Some of the code only run while in debugggin mode, but you don't want to shift to production server or code to run while in live

If the application/compilation running in the debug mode, then the debug code will execute, but if you complied the same code in the release mode, then debug code will not execute.

In Debug environment, output is
If Debug
No If
Conditional Debug
No Conditional
