What are the main differences between designing a relational database and an object database?
When compared to a relational database management system, an object-oriented database stores complex data and relationships between data directly, without mapping to relational rows and columns whereas a relational database stores information in tables with rows and columns.
OR,
The difference Between Relational databases and Object Oriented databases is that a relational database is a database that stores data in tables that consist of rows and columns. Each row has a primary key and each column has a unique name. A file processing environment uses the terms file, record, and field to represent data. While an object-oriented database (OODB) stores data in objects. An object is an item that contains data, as well as the actions that read or process the data. A Student object, for example, might contain data about a student such as Student ID, First Name, Last Name, Address, and so on.
OR,
The main difference between Object Oriented Database and Object Relational Database is that Object Oriented Database is a database that represents data in the form of objects like in Object Oriented Programming while an Object Relational Database is a database that is based on the relational model and object-oriented database model.
A database allows for storing and managing data easily. A relational database, on the other hand, is based on the relational model proposed by E.F. Codd. Object-oriented database depends on object-oriented Programming concepts while the object-relational database is based on features of relational databases and object-oriented databases. In brief, an object-relational database is an advanced and enhanced version of an object-oriented database. In other words, an object-relational database is a hybrid of the relational model and the object-oriented model.
