Let’s understand Database in simple word. A database is a collection of data, usually stored in electronic form. A database is typically designed so that it is easy to store and access information. A good database is crucial to any company or organization. A database management system is important because it manages data efficiently and allows users to perform multiple tasks with ease. A database management system stores, organizes and manages a large amount of information within a single software application. Use of this system increases efficiency of business operations and reduces overall costs. Database management systems are important to businesses and organizations because they provide a highly efficient method for handling multiple types of data. There are five major components in a database environment: data, hardware, software, people and procedures. The data is a collection of facts, typically related. The hardware is the physical devices in the database environment. Operating systems, database management systems and applications make up the software. Examples of people in the database environment are the system administrator, programmers and end users. Procedures are the instructions and rules for the database.  Relational databases use multiple tables and define relationships between them using a schema in addition to data elements. Records and data elements from each table merge, based on the query, and display in the form. Routinely used queries often become reports. A report uses the same query but reports on changes in data over time. There are five major components in a database environment: data, hardware, software, people and procedures.

Importance and Benefits of Database .

Manages large amounts of data :A database stores and manages a large amount of data on a daily basis. This would not be possible using any other tool such as a spreadsheet as they would simply not work.

Accurate : A database is  accurate as it has all sorts of build in constraints, checks etc. This means that the information available in a database is guaranteed to be correct in most cases.

Easy to update data : In a database, it is easy to update data using various Data Manipulation languages (DML) available. One of these languages is SQL.

Data integrity:This is ensured in databases by using various constraints for data. Data integrity in databases makes sure that the data is accurate and consistent in a database.

Security of data :Databases have various methods to ensure security of data. There are user logins required before accessing a database and various access specifiers. These allow only authorised users to access the database.

Easy to research data :It is very easy to access and research data in a database. This is done using Data Query Languages (DQL) which allow searching of any data in the database and performing computations on it.

 

This is the reason Database plays important role in organization as well as into various domains like Banking, Telecom etc. Without Data we cannot do anything if it get stuck or crash there are no use of application , That is the reason nowadays Database like Oracle , Sybase , DB2 is in demand as they are one of the most secured databases . Please go through this blog carefully and let me know if you have any doubts.

In next blog I will come up with other interesting topics.

Thanks.

In other word we can say View is a virtual/logical table which is basically used for security purpose.
