How to make the database in Excel?ДЄll information in the database is contained in the records and fields: Database Structure - Excel tableДatabase - a data set distributed in rows and columns for easily searching, organizing and editing. The only caveat: the Excel program is a versatile analytical tool that is more suitable for complex calculations, computations, sorting, and even for storage structured data, but in small amounts (no more than one million records in the same table, in the 2010 version). That is all that you need for working with databases. After all program features allow you to: sort format filter edit organize and structure the information. Despite the fact that the standard package MS Office has a standalone application for creating and maintaining databases named Microsoft Access, users are actively using Microsoft Excel for the same purpose. A relational database structures the information in the rows and columns. This way, you can create a new database in less than 10 seconds, entering just a username and password.Table is the interface of the workspace of the program. The user will have the same name as the database. To facilitate its clients, with each database NTC Hosting automatically creates a username with all privileges, once the database is created. The syntax for it is: DROP USER An example of how to Delete a User in PostgreSQL DROP USER cashier PostgreSQL users with NTC Hosting

The command for deleting the user is: DROP USER. To delete a user, you must first make sure he is now the owner of the database, otherwise you will receive an error message. Deleting the users will not affect the actual database in any way. You can also delete the whole user, instead of revoking his privileges. An example of how to Revoke Privileges in PostgreSQL REVOKE ALL PRIVILEGES ON money FROM cashier Delete a user The syntax for the REVOKE command is the same as for the GRANT one. Again, just like with adding privileges, you can revoke just certain privileges from a user, or you can also revoke all privileges. Once you have added privileges to a certain user, you can also revoke them. ДЄn example of how to Grant Privileges in PostgreSQL grant all privileges on database money to cashier Revoke privileges from a user The syntax for granting privileges is the following one: GRANT ON TO. This way, if you have several users working on the same database, you can define their access level. Possible privileges, which can be given to a user, are SELECT, INSERT, UPDATE, DELETE, RULE or ALL PRIVILEGES. Without them, he will not be able to do anything. Just like other SQL languages, in PostgreSQL you will have to grant the user privileges to manage a database.

To go into the phpPgAdmin interface, simply click on the respective icon next to the database. In there, you will see a list of all the databases created so far. In order to access the phpPgAdmin, simply go to the 'PostgreSQL Databases' menu in the Web Hosting Control Panel. Here, at NTC Hosting, we use the stable and proven phpPgAdmin, which is very similar to the phpMyAdmin interface, used for managing MySQL databases. There are several web based interfaces for PostgreSQL - pSQL, pgAdmin, phpPgAdmin. The first method is by using a web based interface. PostgreSQL offers two methods of creation of database users, both of which demand a superuser authorization, because only superusers can create new user accounts. This means that all connections to PgSQL have to be performed by the user of the respective database who gives authorization rights via a username and a password. Postgre saves user information in its own catalogue different from that of the operation system where PgSQL is installed.
