1. What is Digitals Network Application System (NAS) architecture?

NAS is a software suite that enables applications to be
integrated across a distributed network of multivendor
systems: NAS services are divided into four main groups:
- Application Access Services which support user interface
(forms based,graphical or character terminal based)
- Communication and Central services which support
communications using electronic mail and EDI
- Information and resource sharing, which supports
database access and compound documents (collection of
images, graphics and conventional text)
- System Access services which provides a standard
operating system interface.

2. What is IBMs System Application Architecture?

SAA is a collection of selected software interfaces,
conventions, and
protocols that are used as a framework for developing
consistent,
integrated applications across the major IBM computing
environments.

Four major components of this architecture are:
- Common User Access (CUA) defines conventions for GUI
look and feel.
- Common Programming Interface (CPI) provides languages,
tools, and APIs that give applications greater portability
and more consistent user interfaces across multiple
platforms.
- Common Communication Support (CCS) supports existing
communications standards, such as LU 6.2.
- Common Applications, written by IBM, will serve as
demonstrations of SAA concepts and make it easy for users
to migrate between systems.

3. How to connect 2 Domain controller using AD sites? What are the requirements?

We can connect two AD by using Sites and Services.
Requirements:
1. two servers installed with win 2000/2003 server
2. installed and configured AD to these servers.

4. Can we execute Truncate from inside a procedure?

We can execute Truncate from inside a procedure using
EXECUTE_IMMEDIATE.

5. What is client server architecture and is it always two tire architecture?

CLIENT SERVER MODEL IS A COMMUNICATION MODEL USED IN NETWORKING
BY THIS MODEL WE SHARE THE WORK LOAD B/W 2 PARTIES -->CLIENT AND SERVER

USUALLY A CLIENT AND SERVER MAY RESIDE ON DIFF. MACHINES BUT IT IS NOT NECESSARY ,THEY MAY ALSO BE PRESENT ON THE SAME MACHINE

IT IS NOT NECESSARY THAT A CLIENT SERVER MODEL IS 2 TIER ,IT CAN ALSO BE 3TIER

6. What is 3 tier, 2 tier and n tier client server architecture?

In three tier system 1st tier is user interface usually
webpages,2nd tier is application server it may be oracle
application server,java application server,3rd tier is
database in which data is stored.
In 2 tier system application server is missing.
In single tier system only server part is present
client part is missing or not present.

8. What is size of NTDS.DIT in win server 2000 and 2003?

In win NT Database is going to store in SAM[security
accounts manager]and the size of data base is 40MB,That's
the reason we can create 40 thousand object in winNT


But in win 2000/2003 database is going ot store in NTDS and
the size of the data box is 12MB and it is extendable, In
win 2003 we can create 1 billion objects

9. What are the three tiers of a three-tiered architecture?

The tiers of a three-tiered system consist of the client
(user interface) tier, business logic tier, and data storage
tier.
