A database management system (DBMS) is a software package with computer programs that controls the creation, maintenance, and use of a database. It allows organizations to conveniently develop databases for various applications. Adatabase is an integrated collection of data records, files, and other objects. A DBMS allows different user application programs to concurrently access the same database. DBMSs may use a variety of database models, such as the relational model orobject model, to conveniently describe and support applications. It typically supports query languages, which are in fact high-level programming languages, dedicated database languages that considerably simplify writing database application programs. Database languages also simplify the database organization as well as retrieving and presenting information from it. A DBMS provides facilities for controlling data access, enforcing data integrity, managing concurrency control, and recovering the database after failures and restoring it from backup files, as well as maintaining database security.

Schema objects do not directly refer to the database's data; rather, they define the structure and organization of the database. Schema objects include tables, views, indexes, and procedures that describe how data is stored and accessed. While they are essential for managing and querying the data, the actual data resides within these defined structures. Thus, schema objects serve as the blueprint for the database's data organization.
Object-Relational Mapping (ORM) typically operates at three levels: Object Level: This is where the application code interacts with objects in the programming language, abstracting the underlying database operations. Mapping Level: This involves defining how objects relate to database tables, including the attributes of objects that correspond to columns in tables. Database Level: At this level, the ORM framework translates the object operations into SQL queries, managing the interaction with the database itself, including data retrieval and manipulation.
To organize your database objects you must use the: Navigation Pane

The package that allows you to view the attributes of a local file on the database server is typically DBMS_LOB in Oracle databases. This package provides functionality for managing and manipulating large objects (LOBs), including file attributes. You can use procedures and functions within DBMS_LOB to retrieve metadata about the files stored in the database.
Database table objects store data. Form objects used by applications provide a visually pleasing or sensible way of accessing or updating data contained in the database tables. This means that the form object is a display specification.

A data dictionary is a document that describes database objects such as tables, columns, and their corresponding data types. It provides information about the structure, relationships, and constraints of the database schema.
