From the year 1963, the term 'database' is very familiar to the world. Database has different types as well as models. If you are interested about the database models, you will get enough information about the database models. From these information about database you will get enough information about database models. Database is considered as the collection of varied information to do some related works. In the year 1970, the database became very famous in the entire Europe. From that time, database is used in various kind of activities including computer applications. There are some major database models to perform some important project s. Let's have a look to the major database models and their features to get an overview about the database and its functionings.

Most of the time database systems are configured around one specific database models. Though it is more and more usual for products to provide support for more than one database model. If we consider one logical database model, there can be varied physical modifications are possible. On the contrary, most of the database products will cater the customer some major degree of control to meet the process of physical modifications. Here we have discussed about the various kinds of database models that are available in the world.

Hierarchical database model:

It is counted as one of the major database models for performing programmed works. According to the Hierarchical model, all the data are configured into a tree-shaped structure, involving a particular upward extending link in each of the record to analyze the nesting and a classified sphere to maintain all the important as well as relevant records in a specified order in each of the same-level list.

Network Model:

Network Model is also acknowledged as one of the important and famous database models. The popular Network model is conceptualized as a flexile way of interpreting objects and their internal relationships. Being a popular database model, the Network Model was invented by Charles Bachman who is an esteemed computer scientist and worked in all the fields of databases. The Network Model was modified into a particular standard detailed description which was published in the year 1969 by the famous CODASYL Consortium.

Relational Model:

It is counted as the best model among all the database models. Being a best database model, the Relational Model is based on the predicate logic and all the set theories. This theory of Relational Model was first formulated as well as proposed in the year 1969 by the Edgar Codd. This model has catered several aspects of database and database theory.
