What is the difference between OODBMS and DBMS?
Third generation of database design theory. DBMS: Database Management System RDBMS: Relational Database Management System OODBMS: Object Oriented Database Management System
What are the type of DBMS?
The main types of database management systems (DBMS) are relational DBMS (RDBMS), NoSQL, and object-oriented database management systems (OODBMS). RDBMS like MySQL and PostgreSQL store data in tables with rows and columns, NoSQL databases like MongoDB offer more flexibility in data storage, and OODBMS are designed to work with object-oriented programming languages.
What are the Advantage and disadvantages of OODBMS?
OODBMS completely negates "impedance mismatch": a problem always faced by a custom software development company in a Relational Database System. In RDBMS, there was enough wastage of time when objects had to be mapped with tables and vice versa. This is completely avoided with OODBMS.In OODBMS, data is described easily through class hierarchy.IN RDBMS, users have to face problems when identifying the records. They had to ensure that no two records had the same primary key. OODBMS completely avoids this aspect because of its unique OIDs.Since interaction between objects and database is done transparently, there is no need for a query language to access data from an Object Oriented Database Management System. But one can still use queries in OODBMS.In OODBMS, a large class can hold several medium-sized classes, which can hold even more medium-sized classes. This means that OODBMs has the ability to handle complex data compared to RDBMS.
What is the difference between sybase and rdbms?
Sybase is a specific product and company that provides relational database management systems (RDBMS). RDBMS is a general term for a type of database management system that stores data in a structured format using tables. Sybase is one of the many vendors that offer RDBMS solutions.
What are advantages of rdbms over dbms?
Some advantages of relational database management systems (RDBMS) over traditional database management systems (DBMS) include data integrity through the use of constraints, normalization to reduce redundancy, support for ACID transactions, and standardized SQL language for data manipulation. RDBMS also offer scalability and flexibility for complex data structures and relationships.

What are limitations of object oriented database model?
Schema Changes: In an RDBMS modifying the database schema either by creating, updating or deleting tables is typically independent of the actual application. In an OODBMS based application modifying the schema by creating, updating or modifying a persistent class typically means that changes have to be made to the other classes in the application that interact with instances of that class. This typically means that all schema changes in an OODBMS will involve a system wide recompile. Also updating all the instance objects within the database can take an extended period of time depending on the size of the database.Language Dependence: An OODBMS is typically tied to a specific language via a specific API. This means that data in an OODBMS is typically only accessible from a specific language using a specific API, which is typically not the case with an RDBMS.Lack of Ad-Hoc Queries: In an RDBMS, the relational nature of the data allows one to construct ad-hoc queries where new tables are created from joining existing tables then querying them. Since it is currently not possible to duplicate the semantics of joining two tables by "joining" two classes then there is a loss of flexibility with an OODBMS. Thus the queries that can be performed on the data in an OODBMS is highly dependent on the design of the system.

Compare dbms and rdbms?
User see the data as Relations [ Tables ] in RDBMS. Where as the user need to know the datastructures and the methods to access them in DBMS. Both store the data required but how the user perceive the data matters.
