Database Management

Many of today’s CEOs and business owners understand the importance of data, but where it lives and how it’s managed is a bit of a mystery. As technology moves towards cloud computing, even more questions arise in how and where data will be stored and managed.

One essential component for managing data is the database management system (DBMS). It’s something that the experts at Secure Data Recovery say every company needs to have for their own security. They’ve helped a number of businesses with database data recovery. Correcting issues and recovering data is much easier when a company has a database management system in place.

What Is a Database Management System?

The database is where the data is collected. A database management system is a software program that gives you much more control over databases and the data they contain. The program uses mathematical operations to:

  • Define data and rules for validating data
  • Catalog and index data
  • Locate data in the database
  • Normalize data so there’s less redundancy
  • Retrieve data
  • Store data and metadata
  • Create storage mechanisms
  • Help maintain the integrity of data
  • Output data in a particular format
  • Establish security rules

The DBMS shouldn’t be confused with a data processing system, which can actually transform and change data. The primary goal of a database management system is to organize data in its original format so that it is readily available and easier to retrieve.

A database management system creates a logical architecture for data by using designations and attributes to create relation-based tables. This creates a much more efficient program compared to file-processing systems.

Query Language

In order to manipulate and retrieve data, the DBMS must be able to talk to the database. Each database management system has a query language that makes it possible for users to apply filters that interact with data. SQL is just one example of query language used by database management systems.

Database Management System Users

The DBMS is a midpoint between the actual database and users. There are three potential users of a database management system.

Administrators

The primary DBMS users are administrators that have full access and permissions. Administrators are tasked with maintaining the database management system and monitoring its use. They are also able to allow access to other users and define what data can be seen.

Designers

Designers create the architecture of the DBMS. They decide what data should be stored in the DBMS and in what format. Designers are also tasked with identifying entities within the data, establishing relationships between data and designing the views for various users.

End Users

An end user is anyone who has been given permission to access the database management system and view the data. Ultimately, the DBMS is made by administrators and designers for end users that need to track and/or analyze the data that’s being collected.

Database management systems can provide different views for different types of users based on the data they need. This multi-view feature can also help improve security by limiting the data that can be seen and accessed.

DBMS Architecture Options

Organization of incoming data is one of the top benefits of using a DBMS. How data is organized and manipulated depends on its architecture.

N-Tier Architecture

Under this architecture schema, the DBMS is divided into n modules that are independent but related. Each n module can be modified and replaced without affecting the rest of the data.

1-Tier Architecture

1-tier or single-tier architecture refers to a system in which all changes are made directly on the DBMS. It is a somewhat complex system that’s typically used by programmers and designers.

2-Tier Architecture

In a 2-tier system, the DBMS isn’t accessed directly like in 1-tier architecture. Instead, an application is used to access the DBMS. The application and database are independent in terms of design, operation and programming.

3-Tier Architecture

The most common type of DBMS architecture is 3-tier. In a 3-tier system, there is a database tier, application tier and a presentation tier. The presentation tier is where end users operate. It’s also the layer where multiple views of the data are provided based on the application.

A database management system allows a company to make better use of the data it collects. By creating a systematic approach for organizing and accessing data databases are no longer simply a storage facility. With the help of a DBMS, data isn’t passive – it’s a powerful tool that can inform and transform a business.
