What is a Database?
Database is a compilation of information related to a particular purpose. From the word itself, it is ” a base of data” or a place where you can store data.
Example: When you ask phone numbers from your classmates or friends and enter it in your phonebook, the phonebook becomes your database. Now you already have a database.
We can create database manually or technologically. Manual database is just like the example above. However, technological refers to computerized database or DBMS.
What is DBMS?
Every day, companies, organizations, or schools are facing a huge amount of information that has to be managed. Just like for example in school especially during enrollment. A thousand of students means a thousand of information. This usual students’ information could be a student ID number, name, birh date and etc. With this thousands of information, how could a school manage? Now, that is the work of DBMS.
DBMS means Database Management System. It is a collection of computer programs that enables a user to create and manage databases. DBMS serves as a storage of information that could be retrieved whenever you like.
Of course, DBMS will not exist without components.
What are the Components of DBMS?
* HARDWARE: The harware component for DBMS is a computer that enables
you to enter and retrieve information.
For general meaning of hardware, just click this link http://en.wikipedia.org/wiki/Hardware
* SOFTWARE: Microsoft Access where you can create and runs DBMS.

* PEOPLE: User of a computer that enters and retrieves information in DBMS.
* DATA: It is simply the data or information you enter in DBMS. DBMS will be useless without data or
information because that is the reason why DBMS is created, to be a storage of important
information needed for further use.
* PROCEDURE AND STANDARDS: This refers to how DBMS is created and for what purpose. Just like for
example, you want to make a database of class list. In creating a class list, you want to have a
student ID number, it’s name, year and course. So, the entering of data only limits only about your
specified field, that is Student ID number, name, year and course. The limitation of your DBMS
maybe referred to as the Procedure and standards because that is how you created your DBMS.
What are the ADVANTAGES of DBMS?
As to what we have discussed above, I think you already realized some advantages of DBMS. Because DBMS is used through computer, it already provides speed. Furthermore, it promotes flexibility, reduces the probability of losing data or information, compact and most of all manageable.
I know you might be confused of some details. But you may understand that as we go further about this soon.
I will tell you some things I know on how to make a computerized database.
For comments or reactions, I will be glad to hear something from you. If you have something to ask, don’t hesitate to do so. I will answer your questions.
