Relational vs object oriented database pdf
The difference between relational database and object oriented database is that the relational data base stores data in the form of tables which contains rows and columns. Every column in the table has its specific name and every row of the table has its own primary key. In the processing of file environment terms such as field, record, file is used to represent data. While in the object

Object Oriented vs Object Relational Relational Database

Preface This book explores the use of databases and related tools in the various applications. Both relational and object-oriented databases are coverd.
Relational Database vs Object Oriented Database. Summary: Difference Between Relational Database and Object Oriented Database is that relational database is a database that stores data in tables that consist of rows and columns.
An object-relational database (ORD) is a database management system (DBMS) that’s composed of both a relational database (RDBMS) and an object-oriented database (OODBMS). ORD supports the basic components of any object-oriented database model in its schemas and the query language used, such as objects, classes and inheritance.
Relational DBMS A relational database is composed of many relations in the form of two-dimensional tables of rows and columns containing related tuples.
When databases first appeared, OOP still wasn’t the way to program. Relational databases, on the other hand, gained a lot of traction. And SQL introduced in the 80’s by IBM quickly became lingua franca of all databases.

Object database Wikipedia

In the world of database technology, there are two main types of databases: SQL vs. NoSQL—or, relational databases and non-relational databases. The difference speaks to how they’re built, the type of information they store, and how they store it. Learn about the differences between the two and which database type you should choose.
An object-oriented model uses objects containing stored values to unite the application and database development, while a relational model uses relations to construct data.
