What is the difference between object-oriented database and relational database?
A Relational Database is designed and maintained following some very well defined rules of logic and algebra. It often portrays a "one to many" relationship between two sets of data, and, less often, a "one to one" and "many to many" relation can be developed. An OO database uses less rigid design parameters, and can be adjusted design-wise to fit almost any kind of data environment. In fact, I'm not absolutely sure there is such a thing as an "object oriented" database, so much as there are database objects that are created and maintained with OO programming. I know that sounds self-referenceing, but that's OO for you... A relational database uses structure to locate and display data values, rather than programming logic. With a correctly designed RDB, finding and displaying data is very simple, compared to earlier network databases. Relational databases also permit the use of JOINS to merge and match sets of data ("relations"), to glean more information from your database that would normally be available.

The E-R model (Entity-Relationship model) is a visual representation of entities, attributes, and relationships in a database, while the relational model organizes data into tables with rows and columns. The E-R model focuses on the logical design of a database, while the relational model focuses on the physical implementation of data storage and retrieval. E-R model uses entities, attributes, and relationships to depict data structures, while the relational model uses tables, keys, and relationships to organize data.

The relationships between users database applications DBMS and database?
The relationships between database applications DBMS and databases is as follows: Databases can be simple or complex. simple databases can be kept in a Microsoft Excel spreadsheet or they can be maintained in a user generated Microsoft Access database which can be programmed to query certain data that has been entered into that database over a period of time. Microsoft Excel and Microsoft Access are also applications that are used to build databases that can be incorporated into DBMS or Database Management Systems. These systems can be extremely complex or they can be simple meaning that maintenance to these systems is not demanding. If the DBMS is complex it may require an entire team of technicians and in some cases engineers.The relationship between users, database applications, databases, and Database Management Systems can be simplified even further - Users can access a database that has been created with a database application to query managed data that is a part of a uniform Database management system.
