Database A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data.A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases.oth a database and its DBMS conform to the principles of a particular database model. Database system refers collectively to the database model, database management system, and database. Physically, database servers are dedicated computers that hold the actual databases and run only the DBMS and related software.

Database schema A database schema (/ˈski.mə/ SKEE-mə) of a database system is its structure described in a formal language supported by the database management system (DBMS) and refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of Relational Databases).chemas are generally stored in a data dictionary. Although a schema is defined in text database language, the term is often used to refer to a graphical depiction of the database structure. In other words, schema is the structure of the database that defines the objects in the database.

How to Divide Fractions by a Whole Number Simplify the fraction. To simply the fraction, you need to find the lowest common denominator, which means that you should divide both the numerator and denominator by any number that divides evenly into both numbers. Since 2 is the numerator, you should see if 2 divides evenly into 12 -- it does because 12 is even.

1 Introduction to the Oracle Database Oracle Database Architecture. An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. data dictionary is created when a database is created. To accurately reflect the status of the database at all times, the data dictionary is automatically updated by Oracle in response to specific actions, such as when the structure of the database is altered.
