Performing common database administrator tasks

This section describes some of the common tasks the HP Vertica database administrator performs.

database management systems and SQL. For more information, see the
Guide.

Creating a database

HP Vertica provides two options to create a database: Management Console or the Administration
Tools. See Create an Empty Database in the

Rules for database and password names

When you create a database, one of your first tasks is to name the database and supply a secure
password. See Creating a Database Name and Password in the

Starting and stopping the database

You can start and stop your database using the Administration Tools, Management Console or

Implementing security

In HP Vertica, there are three primary security concerns:
Client authentication prevents unauthorized access to the database.
Client authorization controls what users can access and change in the database.
Connection encryption prevents the interception of data and authenticates the identity of the
server and the client.
See Implementing Security in the

Creating new database users

Client authentication controls which database objects users can access and change in the database.
To prevent unauthorized access, a superuser limits access by assigning privileges directly to users
or to roles through a series of GRANT statements.
A Management Console administrator can also grant MC users access to one or more HP Vertica
databases through the MC interface.
