Dear all/

I would appreaciate if someone could comprehensively enlighten me on this.
Can anyone answer the following terms in context of installation of SQL 2008 database server.


 What is the recommendation for SQL Compatibility Level requirement (80, 90 or 100)?
 while installation of the database for an application,if the application documentation does not mention it at all.
       

What is recovery model (simple & full). what should be the model if the application does not mention it at all.what is "point in time restore" needs?

What should be the Autogrowth recommendations for db. should the autogrowth turned on or off. if the application does not mention it at all.the application only mentions that you can add filegroups later using application interface when required.


· what should be the sql user for database access.  Application documentation mentions about sa user. what privileges does this user has and is it Ok to use this one.

Might not be the most thorough response, but here are my thoughts.

- What is the recommendation for SQL Compatibility Level requirement (80, 90 or 100)?
Compatibility level can be considered the "version" of the database.
Since there's not specification as to what "version" should be installed, I would go for the highest. Why? Because all your "old" code/functions will work with new "versions" (forward compatibility), while the opposite is not always true.

- What is recovery model (simple & full). what should be the model if the application does not mention it at all.what is "point in time restore" needs?
Simple recovery model should not be an option if you need Point In Time Restore.
Full gives you all the possibilities of restoring a SQL Server Database (as long as you make the appropriate backups), so if no specification is set, I'd go for that one.

- what should be the sql user for database access.  Application documentation mentions about sa user. what privileges does this user has and is it Ok to use this one.
The best practice is to NOT use the SA account for application development.
The reason behind this is that the SA account is an "Admin" account with ALL the priviliges on the server. For security reasons this account should not be used by anyone except the DBA (in most cases it is disabled, I think in SQL 2008 it's disabled by default).

The "optimal" way to go would be to create a new SQL user for this application and grant him only the "necessary" access to the database/server.

Hope it helps.

100 = SQL Server 2008 and SQL Server 2008 R2

Think of SA as (god mode) they have full access to everything in the DB and when configuring connections to other applications its best to use SA account

As been told the sa account is not a safe user to set so what should be the permissions set on another created user. I need a user which can create the initial application database i.e. admin data

What does this "new" user have to do?
The database is only going to have to be created once, if you want you can create it with the SA account (or any other account that can create a database in the server), but use a different account (the new one) as the application user.

the "new" user (not the sa user) is mandatory as far as this application is concerned to create the initial database for the application.Please note that this database setup creates the admin schema to run this application.

Before doing this , the database engine has already been installated with an appropriate user,

SInce the DB administrator would never give the sa user to create this initial database for the applicaion (admin schema) how can another user created (which roles) to enable this.

Also I would appreciate if someone could tell me if I shoud use sql server authentical, windows authentication or mixed mode. How to decide between the three when installing and configuring the database server.

In order to be able to create databases the user must be a member of the dbcreator server role.

SQL Server Authentication is necessary when you're using a SQL user to connect to the database (as in your case)
Windows Authentication is used when you authenticate in the server with your windows user, used with Active Directory.

Mixed mode allows you to connect to SQL Server using either a windows account or a SQL Server user...

Since you need to authenticate with a SQL Server User, you need to enable Mixed Mode Authentication.
