Microsoft SQL Server Setup

 

Introduction

Microsoft SQL Server is an application used to create computer databases for the Microsoft Windows family of server operating systems. Microsoft SQL Server provides an environment used to generate databases that can be accessed from workstations, the Internet, or other media such as a personal digital assistant (PDA).

To follow our lessons, you must have access to a computer in which Microsoft SQL Server 2008 is installed. To start, you must have a computer that runs an appropriate operating system. If you are just learning, you can use a computer that runs Microsoft Windows XP Professional, Microsoft Windows Vista, Microsoft Windows 7 (Professional or Ultimate), Microsoft Windows Server 2003, or Microsoft Windows Server 2008.

Before installing Microsoft SQL Server 2008, make sure you have installed all service packs on your operating system.

Security Principals

A security principal is a person or an object that needs access to a database. The security principal can be considered as one entity or as a group of entities:

Security Principals

This means that a security principal can be considered as a lone entity or as member of a group. For example, a person who accesses a database can be considered an entity. A group of people who perform the same job and have been give the same accecss(s) to a database (or to an object of a database) is considered a collection.

    To add a user, click Add...
  11. This would open a dialog box. First check the location. If it is not displaying the right computer, click Locations... In the Locations dialog box, if you will access the database locally, select the name of the computer and click OK.

You can control the type of access that a security principal can exercise on a machine or a database, based on a level of accecss. There are three levels: Windows, server, and database:

Security Principals

Based on the functionality of a security principal, it can be considered as belonging to a collection.

To help the operating system identify them, each security principal uses a unique number called a security identifier (SID).

Creating an Administrator Account

To actually install Microsoft SQL Server 2008, you must use a user account that has the ability to install an application. If you are using Microsoft Windows XP, Vista, or 7, you should use the Administrator account or create a new account that has administrative rights. The account must also use/have a password.

Author Note

During the installation of Microsoft SQL Server, you must log in, using a username and a password. If you are working in Microsoft Windows XP->7, after the installation, if you want, you can remove the password on the account, but you will not be able to connect to Microsoft SQL Server again. If you want to connect to the server, you will have to use a password again.

Creating an Administrator in Microsoft Windows 7

  2. In the left frame, click Groups

    Select Users, Contacts, or Computers
  7. When the name has been resolved, click OK

From now on, that is, for the rest of our lessons, we will consider that you are using a computer on which you have administrative rights. You must always log in using that account when you start your computer or use an account that has administrative rights.
