Data Models in DBMS: Network Model

We have already discussed our first Data Models i.e. Hierarchical Model in the previous post. In this post let's understand the 2nd Data Models i.e. Network Model.

This model is an extension of the hierarchical model. It was the most popular model before the relational model.

Data Models in DBMS

In the previous post, we discuss about data models and 10 types of data models are there.

Let's understand first data models i.e. Hierarchical Model in more details.

Today, we will see Data Models The process of creating a model for the storage of data in a database is termed as data modeling. Data models are used in database management systems to display how data is related, updated, accessed, and stored.

In the previous post, we see DBMS Architecture. In this post we will discuss DBMS Architecture types in details. As we discussed there are three types of DBMS Architecture. 1-tier Architecture 2-tier Architecture 3-tier Architecture

Today, we will understand DBMS Architecture. A DBMS design is represented by a database architecture. It supports in the creation, growth, use, and maintenance of the database management system.

In this post we will see RDMS vs DBMS. DBMS 1. It has no relations and store smaller amounts of data. 2. It can only access one piece of data at once. 3. Fetching of data becomes slower when working of data is large. 4. It does not provide database normalization 5. It has Lower security level.

In this post we will see RDMS and its features. A relational database management system (RDBMS) is a group of tools and features that enables IT teams and other users to build, maintain, and interact with relational databases in various ways.

Hi Everyone, Today we will discuss about history of Relational Database. There was a computer scientist whose name is Edgar F. Codd. In June 1970, He published an paper “ A Relational Model of Data for Large Shared Banks.”

Hi Everyone, Today we will know about the types of Databases. There are various types of databases used for storing different varieties of data: 1. Relational Database - This database uses the relational data model, which stores data in the form of rows (tuples) and columns (attributes), which are combined to make a table (relation)

In the previous post, we discuss about the database. Today we will discuss about File Based Database. File Based Database was introduced in 1968. The file system is essentially a method of grouping files on a hard drive or other type of storage medium.
