How to resets the IDENTITY back to the SEED without using truncate table command?

TRUNCATE TABLE : TRUNCATE TABLE is a statement that quickly deletes all records in a table by deallocating the data pages used by the table. This reduces the resource overhead of logging the deletions

DELETE TABLE : DELETE TABLE statements delete rows one at a time, logging each row in the transaction log, as well as maintaining log sequence number (LSN) information. Although this consumes more database resources and locks, these transactions can be rolled back if necessary

Note:When large tables require that all records be deleted and TRUNCATE TABLE cannot be used, the following statements can be used to achieve the same result as TRUNCATE TABLE:

• DELETE from "table_name"
• DBCC CHECKIDENT("table_name", RESEED, "reseed_value")

eg: DBCC CHECKIDENT("Table1",RESEED,0)

Object Oriented Programming – Encapsulation is not just hiding data!

Encapsulation 
 
Encapsulation is hiding of process; hence you hide the data. Not the vice versa.

Abstraction
Abstraction is a concept which facilitates to extract out the essential information of an object.

for example

So, what exactly an Abstraction is?

Abstraction facilitates the easy conceptualization of real world objects, by eliminating the unnecessary details of the object. Unnecessary details? Yes, all the similar objects when you generalize, you will drop the uncommon details about the objects.

E.g., when you model a generic prototype for CRT Television & a Plasma Television, you look for details like Type of screen, Height, Width, thickness etc.; these are necessary details for a Television. But a Television object doesn't need to have details of what kind of Electron it will bean to power the CRT, what kind of liquid plasmas it will use to power the Plasma TVs. These kinds of details are unnecessary details.
