A database is a combination of digital and hardware bases where the data can be stored. Storage plays a crucial role for Database Management Systems particularly helps in storing and retrieving information stored. The information can be further analysed for developing an understanding of the market. The decisions can be made on the basis of outcome that is relevant to market dynamics, scope and demand. The data stored in the database gives sight to an organization to make an informed decision. This is the new fuel for the 21st century. A Database management system is an application that works in tandem with the administration department for storing and processing multiple datasets at the same time. The database can be a centralized, decentralized, or fragmented based on the business requirements.
The first level computer was invented in early 1950. By the time India was celebrating and embracing freedom, the western countries were developing technologies that are destined to shape the world. The 1950 computer was very basic and worked on Binary Language, mostly used for performing the calculation, establishing communications, and helping scientists with Aviation Physics. At this time, the computer was not meant for Businesses. With globalization, demand for automation of redundant and mundane tasks started picking up.
The first system to be replaced is the ledger system used in Financial Accounting. The inventions in the computer sector picked up by the year 1961. The world started witnessing fast, accurate and reliable computers. A need for a programming language for businesses emerged. Computer Scientists had developed a Common Business Oriented Language COBOL for programming computers to perform specific business-oriented tasks. They were based on Navigational Databases. In these databases, the files can only be stored manually for record-keeping.
By 1991, when we witnessed Economic Reforms the western world was dwelling on using computer systems for recreational purposes. Therefore, by acknowledging the demand, scientists came up with a solution called NoSQL. The limitation of computers being used only for businesses is now being conquered by the NoSQL system. In these systems, the unstructured data such as Art, Photographs, and Music, etc. will be linked with an object and simultaneously it can be managed and stored effectively. These systems were launched under Java Relational Database Technology. The Data in the system can now be linked with a variety of keys such as Primary Key, Secondary Key, and Foreign Key. The object-oriented Database Management System has revolutionized Database technology and paved the roadmap for further inventions.
A single file database stores data in the form of a text file, wherein each line the data was separated by commas, delimiters, etc. Each line hold at least one record. This system contains a simple structure in the form of sheets.
A multi-file database is a relational database, where multiple files are linked with special key pages. These databases are more functional and provide many linkages which help in reading, creating, updating, and deleting data. A relational database system can be further classified into four types such as
Database Systems are complex and serious question needs to be considered while choosing a right system
If your need is small and has limited requirements of updating and filtering data then a spreadsheet will be a perfect option for you. However if you may have huge requirements of data and require multiple edits at the same time, then a relational database will be needed to consider.
The data as it may suggest is the information stored somewhere which can be used in multiple ways. Globally big corporations rely on data for decision making, for instance.
Data and its management is an evergreen field and it has enormous potential. For all tech companies, a database administrator is a must-have position. Therefore making a career in this field is a smart decision.
With data comes vulnerabilities, there is huge risk of possible cyber-attacks on IT companies and other corporations, and which may result in losses in billions of dollars, globally! Therefore, this has opened a new array of jobs for Database security managers.
The first smartphone was launched in the year 2007 and by just over 14 years, we have witnessed a huge supply and demand change. The online presence is now a quintessential part of every business. The investment and returns related to data-driven analysis are at an all-time high. With the help of technological advancement, we are now adding more data every hour to our database system than we had added from the beginning of humankind to the year 2007.
To begin an in-depth journey in Database technology please refer to the courses offered at EdifyPath. We have a bunch of dynamic courses available which require basic computer knowledge and builds the base to become an expert in that particular field. This has been made possible with the help of our excellent mentor support program by successfully addressing every query with an accurate response.
