Distributed databases: A DBMS does not provide support for distributed databases while a RDBMS does. ACID implementation: A RDBMS bases the structure of its data on the ACID (Atomicity, Consistency, Isolation,
In this blog, we will cover one of the topics of the extended E-R Model. i.e Generalization. Generalization Generalization, as the name suggests, is a process of generalizing two or more lower-level entity types into a higher-level entity type. Entities are clubbed or grouped together to ...
In a database management system (DBMS), a serializable schedule is a sequence of database actions (read and write operations) that does not violate the serializability property. This property ensures that each transaction appears to execute atomically and is isolated from other transactions' effects....
A database model is primarily a type of data model. Depending on the model in use, a database model can include entities, their relationships, data flow, tables and more. For example, within a hierarchal database mode, the data model organizes data in the form of a tree-like structure ...

The Hierarchical Model was the first database management system model to be used in databases. This type of DBMS organizes data into a tree-like structure, which is useful for managing data with a parent-child relationship. It is characterized by its fast response times and efficient data retri...
information about the physical storage of your data, such as the location of files and the use of indexes and other performance optimization techniques. The physical model is used to guide the actual implementation of a database and is therefore specific to the DBMS or application software you ...
