Simply stated, that is an acronym for an advanced 'Database Management System', which is a software package that would facilitate the development of various applicable databases.

Architecture is the frame work of the Database Management System. They are simply classified into logical and physical.
In 3 tier architecture, client directly interacts with intermediate server and intermediate server will directly interact with database server.
A database is an organized collection of data, today typically in digital form. The data are typically organized to model relevant aspects of reality (for example, the availability of rooms in hotels), in a way that supports processes requiring this information (for example, finding a hotel with vacancies).The term database is correctly applied to the data and their supporting data structures, and not to the database management system (DBMS). The database data collection with DBMS is called adatabase system.
We know that three view-levels are described by means of three schemas. These schemas are stored in the data dictionary. In DBMS, each user refers only to its own external schema. Hence, the DBMS must transform a request on. a specified external schema into a request against conceptual schema, and then into a request against internal schema to store and retrieve data to and from the database. The process to convert a request (from external level) and the result between view levels is called mapping. The mapping defines the correspondence between three view levels. The mapping description is also stored in data dictionary. The DBMS is responsible for mapping between these three types of schemas. There are two types of mapping. (i) External-Conceptual mapping (ii) Conceptual-Internal mapping External-Conceptual Mapping An external-conceptual mapping defines the correspondence between a particular external view and the conceptual view. The external-conceptual mapping tells the DBMS which objects on the conceptual level correspond to the objects requested on a particular user's external view. If changes are made to either an external view or conceptual view, then mapping must be changed accordingly. Conceptual-Internal Mapping The conceptual-internal mapping defines the correspondence between the conceptual view and the internal view, i.e. database stored on the physical storage device. It describes how conceptual records are stored and retrieved to and from the storage device. This means that conceptual-internal mapping tells the DBMS that how the conceptual! records are physically represented. If the structure of the stored database is changed, then the mapping must be changed accordingly. It is the responsibility of DBA to manage such changes.

no, Java is not dbms.. Java is a programming language Dbms is database
dbms
Three types of DBMS (Database Management Systems) include relational DBMS, object-oriented DBMS, and NoSQL DBMS. Relational DBMS organizes data into tables with rows and columns, object-oriented DBMS stores data as objects and classes, and NoSQL DBMS handles unstructured and semi-structured data with flexible schemas.
In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.

What is the purpose of dbms?DBMS is a software that organises the creation, storage and maintenance of Databases for end users.
DataBase Management System (DBMS)is a software package# it allows data to be effectively stored, retrieved and manipulatedand # the data stored in a DBMS packege can be accessed by multiple users and by multiple application programs like (SQL Server, Oracle, Ms-Access) .Types of DBMS# Hierarachical DBMS (HDBMS)# Network DBMS (NDBMS)# Relational DBMS (RDBMS)# Object Oriented DataBase(OODB)# Distributed DBMS (DDBMS)
Polyhedra DBMS was created in 1993.
DBMS is short for database management system . DBMS is the collection of related records.
DBMS is database management system and it stores data that are related. DBMS maintains data security and integrity as well.
