Most database software includes a graphical user interface GUI consisting of structured fields and tabular forms that give users a centralized view of the data present in a database and the tools to manipulate and query it. Structured Query Language SQL commands are also typically used to interact with databases through the software. Administrators input SQL queries to prompt the system to perform an action, such as retrieving a specific set of data. However, there are also databases that use other means for retrieving information in addition to SQL.
The most widely-used databases consist of a basic set of columns and rows that display information retrieved using SQL. However, more complex software has been developed in recent years to accommodate the massive amounts of unique data collected by organizations, especially enterprises. These tools are multi-layered, use a variety of query languages and support more storage formats , such as XML. Database software is available both as a commercial product and open source software.
Commercial options often have the advantage of vendor support. While open source software may lack this support, they make up for it with more customization and free downloads. Charles W. Bachman developed what is considered to be the first database software management system in At the time it was called the Integrated Database system. IBM quickly saw the value of a program that could easily access and pull information from a database and set out to make their own.
These two programs are largely considered to be the forerunners of modern database management software. As more companies tried to follow suit, the market became flooded with general use databases that lacked standard functionality.
However, these systems were still complex and required substantial training to manage. In the s, relational databases hit the market. These tools offered a much simpler system that could be implemented by a variety of organizations without the need for database experts. This quickly became the industry standard.
These first relational databases used SQL for database interaction. Decentralized Finance DeFi is a blockchain-based financial system.

This database is maintaining information concerning students, courses, and grades in a university environment. The database is organized as five files:. Here, are the important landmarks from the history:.
In a Hierarchical database, model data is organized in a tree-like structure. Data is Stored Hierarchically top down or bottom up format. Data is represented using a parent-child relationship. The network database model allows each child to have multiple parents. In this model, entities are organized in a graph which can be accessed through several paths. This model is based on normalizing data in the rows and columns of the tables. Relational model stored in fixed structures and manipulated using SQL.
In Object-oriented Model data stored in the form of objects.
