which focuses on preventing inconsistencies within the database, view serializability in DBMS focuses on providing users with consistent views of the database. In order to better understand view serialization in
In non-relational systems, data is often grouped intoflexible schemasthat can evolve over time, making them ideal for apps that require rapid development and scaling. For example, a document store might hold all customer interactions in one document per customer, avoiding the rigid structure of re...
Storage engine.This basic element of a DBMS is used to store data. The DBMS must interface with a file system at the operating system (OS) level to store data. It can use additional components to store data or interface with the actual data at the file system level. Metadata catalog.Some...
In a structured query language (SQL) database, for example, a view becomes a type of virtual table with filtered rows and columns that mimic those of the original database. While the table generated in a view is permanent, the data within fields is subject to change according to the sourc...
The core component of every DBMS is called thedatabase engine. It is the software that interacts directly with the underlying storage system or file system and orchestrates the interactions between modular sub-components that enable the engine to manage and manipulate data in the database system. ...
A DBMS helps to ensure the integrity of data stored in the database by validating and enforcing rules on how it is entered and stored. For example, a DBMS may check for errors such as duplicate entries or data types that don’t match. ...
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 represent a more generalized view. In this process, the common attributes of two or more entities combine to ...

For example, organizations that process payment card information must use and store payment card data securely, and healthcare organizations in the USA must secure private health information (PHI) in line with the HIPAA standard. But even if your organization is not subject to a regulation or ...
In DBMS, the data is stored as a file in hierarchical form, the associated records don’t have any relation to each other. It does not support distributed databases and normalization of data is also not present. DBMS can only handle a small amount of data efficiently as compared to RDBMS....
