Advantages of DBMS: Organize Your Database!
One smart choice for a business to make is to use the Database Management System (DBMS) approach to data storage. Organizing your data in a database has many advantages. These range to implementing data access controls to reducing data redundancy.
Not only can companies benefit internally from DBMS use, the security of personal information is something that clients can feel secure about. Here is a course entitled Database Management System that helps you understand the database concepts at the fundamental level.
Basically, a database management system (DBMS) is a program collection allowing end-users to control, maintain and create database records. Features of a DBMS mainly address database creation for record interrogation, queries and data extraction.
The difference between an application development environment and a DBMS system ranges from personnel to data usage. You might also want to check out this course entitled SQL Database for Beginners that helps you learn simple and easy Microsoft SQL.
Let’s look at some of the common advantages of using a DBMS:
Advantages of Personnel
A system of DBMS consists of database administrators and managers overseeing the entire operation of DBMS. Their duties primarily are maintaining the database records, making sure primary scheduling is done daily and loading program releases. Applications development consists of a systems analysis, computer technicians and programmers with the job of finding errors in software for testing.
Interrogation of Records
Several programs making up records interrogations program are designed for providing end-user information. General inquiry programs, report generator and Query are some of these programs. Query is of course the most popular program, which lets end-users develop basic skills of programming by creating simple programs of data using a language of Query to get data extracted. For records interrogation, Query programs are powerful utilities.
In a system of DBMS, end users can get their favorite programs cataloged to delete, edit or view data. Every user can get routines copied to a catalog file which the user has defined for database management. End users use a personal tool which is the catalog system to run programs without having a specialist for applications design programs for them.
Unique Analysis of Data
Aside from being very useful for retrieving and storing data, database management systems are also useful for data analysis. Tables of data can be set up representing any relationship between data. Using keys specific to tables within the database, this lets users draw inferences from the information.
The database has the capability of using algebra that is relational in representing relationship that occurs in the data itself. This can be done through the use of Structured Query Language (SQL) to query the database. To protect the integrity of new data, a database can also be set up using guidelines. To help in data analysis, all these tools are available in DBMS.
Increased Security of Data
For any business, data security is a top priority. A DBMS lets managers control data access. This control maintains the security of data from each user without a need-to-know. In a database, the propriety information of the company can be kept secure along with customer and employees personal information.
You are also protected against data loss with DBMS by using recovery and backup services. DBMS backup stored off-site protects against potential loss from natural disasters and also protects against loss of data through computer error.
Increased Control and Ease in Data Access
For the database, a DBMS can set access controls. Certain users can get data access if they need to for their job function. The number and type of users allowed access to the database information can be restricted. This way, protected information can be kept private from every user of the database.
A system of DBMS lets users have immediate access after logging into the system. The ease of being able to access data can increase employee job satisfaction and productivity.This is because systems of DBMS have centralized databases. An end-user can access data without application program developers having to create programs for access or without programmer interruption.
The record structures and database are already built into the software. In this area, the advantages are access to records and data structures. With this line of thought, you might want to check out Data Models in DBMS: Manage Your Data Right! Which shows you all the different DBMS data models.
DBMS Lessens the Redundancy of Data
One major problem that many businesses face is data redundancy. Companies might have many copies of the same type of data stored in various locations. Records then need to get an update in every location if there is a change in information.
Ideally, there is an update of each copy of the data every time there is a change in information. Except, this is not always the case. What DBMS does is that its gets the data saved in just one single location and lets every user access the same data version. When there is an update on the data, there only needs to be a change in one location.
Particularly Advantageous to Information Systems
Without a DBMS, cataloging, controlling and organizing data, information systems would be a conglomeration of organized data. Ultimately, a DBMS provides data file maintenance and implements control to ensure data integrity.
It is extremely important to catalog files in a DBMS. There are various types of files ranging from Query programs, computer code to record maintenance programs and system utilities.
Each of these has a uniquely structured file which a ‘schema’ identifies. Without this file structure process, all the files would be hard to operate and access. Within a DBMS, a file structure provides orderly structures for management and accessing files.
