what is the difference between hirarchical,network and relational database model?
The hierarchical data model organizes data in a tree-like structure with a single parent for each child record. On the other hand, the network data model allows for multiple parent-child relationships, creating a more flexible and complex network of interconnected records. In the hierarchical model, relationships are one-to-many, while in the network model, relationships can be many-to-many.
A distributed database is a collection of databases stored on multiple computers and accessed through a network, allowing for data to be distributed across different locations. Distributed processing, on the other hand, refers to breaking down a task into smaller parts that are processed on multiple computers simultaneously, enabling faster computation by leveraging the collective resources of multiple machines.
The difference between architecture and topology is logical vs physical. Architecture is about the logical design of something. Topology is about the physical elements required to enable the architectural design. The difference between architecture and topology is logical vs physical.

It depends on how well the network database is protected. Measures such as encryption, access controls, and regular security audits can help ensure the security of personal information stored on a network database. However, no system can be 100% secure, so it's important to continually monitor and update security measures to minimize the risk of data breaches.
(computer science) A database maintained in physically separated locations and supported by a computer network so that it is possible to access all parts of the database from various points in the network.
We know a database is one that stores data related to each other. A network database is just like network database only difference between them is, in network database records are connected by means of a link.
A relational database is a type of database, so in one sense there is no difference. There are various kinds of database. A relational database is one type. Others include network and hierarchical.
Network Database
Hierarchical and network
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.
A database is a file. A database server is a computer that shares that file over a network.
The hierarchical data model organizes data in a tree-like structure with a single parent for each child record. On the other hand, the network data model allows for multiple parent-child relationships, creating a more flexible and complex network of interconnected records. In the hierarchical model, relationships are one-to-many, while in the network model, relationships can be many-to-many.
In network model of database , all data is related to each other through a link. By a link we mean that it is an association between precisely two records/data . In hierarchical model records are organized as trees rather than arbitrary graphs.
There are four basic and main database management systems that are used today. Those four include hierarchical, network, relational and object-oriented.
An introduction to the concepts involved can be found in this place: http://www.unixspace.com/context/databases.html
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.
