What is the difference between oodbms and ordbms?

Object-oriented database management systems (OODBMS) store data in a way that aligns with object-oriented programming concepts, allowing for complex data structures and relationships to be easily represented. On the other hand, object-relational database management systems (ORDBMS) combine relational database capabilities with object-oriented features, enabling users to work with both traditional relational data and more complex data types. ORDBMS often use SQL as the query language, whereas OODBMS may use object query languages.

What are Inheritable attributes?

Inheritable attributes are characteristics or properties of an object in an object-oriented programming language that can be passed down from a parent object to its child objects. Inheritance allows child objects to inherit the attributes and behavior of their parent objects, promoting code reuse and maintaining a hierarchical relationship between objects.


What is the difference between meta data and attributes?

Metadata provides information about a piece of data, such as its size, format, or author. Attributes, on the other hand, are characteristics or properties of an entity, object, or file that define its features or behavior. In essence, metadata describes the data itself, while attributes describe specific qualities or traits of an entity.


What is the difference between aggregation and association in DBMS?

AssociationAssociation is a relationship between two objects. In other words, association defines the multiplicity between objects. You may be aware of one-to-one, one-to-many, many-to-one, many-to-many all these words define an association between objects. Aggregation is a special form of association. Composition is a special form of aggregation.Example: A Student and a Faculty are having an association.AggregationAggregation is a special case of association. A directional association between objects. When an object 'has-a' another object, then you have got an aggregation between them. Direction between them specified which object contains the other object. Aggregation is also called a "Has-a" relationship.
