Over the years now, management and storage of data has significantly transformed from the file-card box, via the first (file based) digital version, to the modern database systems. Most companies and large organizations are heavily relying on the database approach system in order to keep track of their daily transactions, personnel data, and inspection and training programs. The success of our jobs and national security rely heavily on the maintenance and tracking of data. Almost all common personal computer database programs at our work places use the database approach method. A database is a collection of interrelated data stored in a database server. A major goal of the database is to provide means of storage and retrieval of data in a manner which is fast and efficient. That is why, the database approach is dominant now and will dominate in the future. There are many benefits of using the database approach and we will discuss them in relation to this analysis.
In database approach, a single data repository that is defined once then accessed by several users is maintained .A crucial phenomenon of this approach is that the database system does not only consist of data but also a complete definition and description of these data. These descriptions range from details about the extent, the structure, the type, and the format of all data to the relationship between the data. These definitions are stored in a system catalog known as the metadata. Nevertheless, a software application does not need any knowledge about the physical data storage like format, or encoding it only communicates with the database management system via a standardized interface with the help of a standardized language such as the SQL. Ultimately, this approach will suit best on any type of database for instance; banking, finance, enterprise information, insurance and airline databases.
The other characteristic of database approach is that it will allow multiple users to access the database at the same time and sharing of data is possible. The database contains concurrency control software which ensures that multiple clients updating the same data do not face any interference. This adds to another advantage of the database approach whereby it allows for multiple views to be created. View is a “virtual table” since the physical records stored do not occupy any space. Data is held in such a way that changes to the database structures do not in any way affect the programs used to access the data. In addition, since each item of data is held once there is no danger of item being updated on one system and not on another Nonetheless, database approach ensures that only authorized users are allowed access to data. The use of passwords and encryption of information are among the methods used to secure personal data.
Data approach is dominant because of its persistency in data meaning that in a database system all data is maintained as long as it is not deleted explicitly. Changes of a database done by a transaction are persistent. For example, in case of a system crash a completed transaction cannot be legible to any danger. People have to no longer wait in long queues to make withdrawals or transactions since database management systems have made it easy for people to transfer and receive money across the globe in just a click of a button.
Basing on the points given it is important to realize that without a database management system approach; there will be a lot of energy and time wasted in terms of storing and retrieving data. Database approach has made it possible for multiple users to view the same data over a wide range of kilometers across the globe. Without this, there would be no connections and interactions and the world will be a boring place to live in.
