Abstraction, Inheritance, Encapsulation, and Polymorphism.

An object-relational database (ORD), or object-relational database management system (ORDBMS), is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language. In addition, just as with proper relational systems, it supports extension of the data model with custom data-types and methods.

The formal definition of database schema is a set of formulas (sentences) called integrity constraints imposed on a database.

✰ Conceptual schema- a map of concepts and their relationships.
✰ Logical schema- a map of entities and their attributes and relations
✰ Physical schema- a particular implementation of a logical schema
✰ Schema object- Oracle database object

The primary key that is referenced in the other table (linked via the other tables Foreign Key).

Foreign Key is how you link the second table to the primary tables Primary Key (or Reference Key).

A Data Source Name (DSN) is the logical name that is used by Open Database Connectivity (ODBC) to refer to the drive and other information that is required to access data. The name is used by Internet Information Services (IIS) for a connection to an ODBC data source, such as a Microsoft SQL Server database. To set this name, use the ODBC tool in Control Panel.

print ("circularn");
}
