1. Relational Model : Newer database model; Network Model - Older database model
2. The network model structures data as a tree of records with each record can have multiple parent and child records, forming a lattice structure.
The basic data structure of the relational model is the table, where information about a particular entity (say, an employee) is represented in columns and rows
3.The relational model has strong mathematical foundation with set theory and predicate logic. Network Model has no strong mathematical background.
4. Relational model is the most flexible of the database models. Network model is not very flexible.
5. Relational model has widespead use. Network model has limited use.

What is the difference between database and relational database?
A database is something that stores data. Using tools called Database Management Systems(like Oracle, Informix, Sybase, DB2), you can create, view, modify, and delete databases. Databases can be -Relational -Object Oriented -Object Relational Relational database stores data in tables(called realtions). These tables are related to each other.Just like in our family, our relations are related with each other. In Object Oriented Databases, the information is stored in the form of Objects as in Object Oriented Programming.OODBMS makes database objects appear as programming language objects in one or more porgramming languages. Object relational databases combine the features of both Object Oriented as well as Relational databases. Here you can not only store simple data like text in relational, but you can also store complex objects like images, audio and video in tables.

What are the difference between hierarchical database and network database?
Hierarchical databases organize data in a tree-like structure with parent-child relationships and a strict one-to-many hierarchy, while network databases use a more flexible model with many-to-many relationships through pointers or links between records. Hierarchical databases are faster for accessing data along predefined paths, while network databases allow for more complex data relationships but can be more complex to manage.
Difference between database and relational database?
A database is a collection of data organized for easy access and manipulation, while a relational database is a type of database that stores data in a structured format using tables that are related to each other through keys. In a relational database, data is organized into rows and columns, and relationships between tables can be established using keys.
What are main software modules of a dbms?

What is main difference between dbms rdbms why it is called relational database?
There are mainly three different Database architectures and they are network, hierarchical and Relational. The DBMSystems that follow the Relational architectural concepts are known as RDBMS. This is supposed to be superior in design and performance to the other two and there are, to my knowledge, no functional DBMS following the other two concepts in the market today.

Difference between network model and hierarchical model and relational model?
The relational model is a model in which data is isolated by object and foreign keys to those objects which is organized in tables with multiple columns or attributes. The hierarchical model is a model in which the data is organized in a tree structure that allows repeating information using parent/child relationships.

What is High-level nature of hierarchical network and relational database management system?
A Relational Database Management System (RDBMS) is a Database Management System (DBMS) that is based on the relational model as introduced by E. F. Codd. Most popular commercial and open source databases currently in use are based on the relational model.A short definition of an RDBMS may be a DBMS in which data is stored in the form of tables and the relationship among the data is also stored in the form of tables.Network topology is the physical interconnections of the elements (links, nodes, etc.) of a computer network. A local area network (LAN) is one example of a network that exhibits both a physical topology and a logical topology. Any given node in the LAN has one or more links to one or more other nodes in the network and the mapping of these links and nodes in a graph results in a geometrical shape that may be used to describe the physical topology of the network. Likewise, the mapping of the data flows between the nodes in the network determines the logical topology of the network. The physical and logical topologies may or may not be identical in any particular network.Hope this helps!Inclus - We provide individual and corporate training(Inclus.net)Educate, Learn & Serve
What database management systems are there?
There are four basic and main database management systems that are used today. Those four include hierarchical, network, relational and object-oriented.
Where can one compare the 3G network coverage of different telecommunications companies?
There are many places on the internet where one could compare the 3G network coverage of different telecommunications companies. One way would be to take the coverage maps from competing companies' sites and compare them that way.
What is a good way to represent a database?
Relational model of database is a good way to represent the database. Also network data model and hierarchical model can be used depending on the requirements.
