Both RDBMS and ORDBMS can be considered database management systems. RDBMS and OODBMS are database management systems.
What is RDBMS?
RDBMS stands for Relational Database Management System and is a piece of software used to organize and manipulate relational databases. The system allows data to be organized in tabular format using foreign keys and keys, with relationships between tables being managed via foreign keys and keys.
RDBMSs are responsible for storing, retrieving, updating and managing data as well as ensuring its integrity as well as supporting different operations with SQL (Structured Query Language). These systems have long been utilized as they form the backbone for applications requiring structured data storage/retrieval needs.
Definition of ORDBMS
ORDBMS (Object-Relational Database Management System) is software that combines features of relational databases with object-oriented programming concepts like inheritance, encapsulation and polymorphism to expand RDBMS capabilities and features.
ORDBMSs provide similar capabilities as RDBMSs by organizing data into tables while also permitting for the storage and manipulation of complex objects. ORDBMSs provide user-defined data types, functions and methods, providing a flexible yet expressive model capable of accommodating complex structures like multimedia files or semistructured data sets.
ORDBMSs are similar to RDBMSs in that they utilize SQL for data manipulation and querying purposes; however, in addition they feature additional extensions of SQL for managing objects and their relationships - enabling object-oriented principles for their creation, modification and retrieval.
ORDBMS combine the relational model and object-oriented features to offer developers a unified way of working with structured data as well as object-oriented objects. They're a useful solution for applications that need to manage complex data structures while taking full advantage of relational databases' advantages.

Characteristics and features of RDBMS
Relational database management systems (RDBMSs) boast numerous features and characteristics that make them popular for handling structured data efficiently and securely. Each RDBMS has several key characteristics.
Tabular Structure: RDBMS uses tables as its data storage medium, with columns representing entities or concepts and rows representing attributes or properties for efficient querying. This tabular format makes data retrieval faster.
Data Integrity - RDBMS enforces data rules and constraints to maintain data integrity, supporting primary keys that identify each row in each table uniquely and foreign keys that establish relationships between tables. These constraints prevent data anomalies while guaranteeing data consistency.
ACID Compliance: RDBMSs must conform to ACID properties (Atomicity Consistency Isolation Durability) in order to guarantee data integrity and ensure reliability when processing database transactions. ACID compliance ensures this reliability.
Query Language: RDBMS utilizes Structured Query Language (SQL), its standard query language, to communicate with its database. SQL allows for declarative data definition and manipulation using declarative statements such as insert, update and delete statements to query their tables effectively and efficiently. Users can retrieve, insert or delete their desired information using powerful yet straightforward query statements.
Data Independence: RDBMSs provide an intermediary layer between applications and their data storage needs. Data independence enables applications to interact with data through logical structures such as tables and views without having to consider physical storage details.
Scalability: RDBMSs provide scalable solutions through the addition of additional hardware resources and distributed systems, which can accommodate an expanding amount of data or user load. They also feature partitioning data partitioning mechanisms as well as clustering and replication tools in order to spread workloads over multiple servers.
Security and Access Control: RDBMS features robust security measures to protect data against unwarranted access, such as user authentication, role based access control and data encryption to maintain privacy and confidentiality of user records. In addition, auditing capabilities help track database activity to maintain accountability of records.
Data Consistency & Atomicity: RDBMS ensures the atomicity and consistency of transactions by mandating that all changes made within one transaction be committed, or none at all. Data consistency can also be maintained by preventing partial updates that compromise its integrity - the integrity of your database being secured as such.
Data Concurrency: RDBMSs provide concurrent access to databases with locking and transaction isolation mechanisms that permit multiple users to simultaneously work on them without interfering with one another's data or transactions.
Data Backup and Recovery: RDBMSs provide mechanisms for data recovery and backup to protect against system failure or data loss, including regular backups, recovery at specific points in time, transaction logs to ensure data availability, etc.
RDBMSs are widely recognized, reliable and efficient solutions to manage structured data across many applications and industries.
Characteristics and features of ORDBMS
Object-Relational Database Management Systems (ORDBMS), which combine relational databases with object-oriented programming to offer various features and characteristics which extend RDBMS capabilities, offer both features and characteristics unique to ORDBMSs as well as those found within RDBMS systems. Here are some of the main characteristics and features associated with an ORDBMS:
