A database management system (DBMS) is software that allows users to create, access, modify, and manage data in a structured database. A DBMS provides an interface between users and the database, ensuring data is organized and accessible. Common applications of DBMSs include banking, airlines, universities, telecommunications, finance, sales, manufacturing, and human resources. The top 10 DBMS software programs are Oracle, IBM DB2, Microsoft SQL Server, SAP Sybase ASE, Teradata, ADABAS, MySQL, FileMaker, Microsoft Access, and Informix. The main types of DBMSs are relational, hierarchical, network, and object-oriented. Relational DBMSs are the most widelyData Base Management System

A data model is a set of concepts that define the structure of data in a database. The three main types of data models are the hierarchical model, network model, and relational model. The hierarchical model uses a tree structure with parent-child relationships, while the network model allows many-to-many relationships but is more complex. The relational model - which underlies most modern databases - uses tables with rows and columns to represent data, and relationships are represented by values in columns.Basic DBMS ppt

This document compares database management systems (DBMS) to traditional file-based systems. A DBMS organizes related data across multiple tables and provides interfaces for defining, manipulating, and securing data. It reduces redundancy and improves consistency, integrity, and concurrent access. Traditional file systems store flat files that are less structured and do not allow relationships between files. A DBMS provides advantages like redundancy control, data security, and sharing that file systems lack.Database Management System

Codd's 12 rules are a set of rules proposed by Edgar Codd to define what is required for a database management system to be considered relational. The rules include that all data must be represented in tables and columns, all data must be logically addressable, null values must be supported systematically, the database structure must be accessible through queries, and the system must support set-based operations like inserts, updates and deletes. The rules also require physical and logical independence between the application, data and constraints.RDBMS

A multimedia database management system (MM-DBMS) manages different types of data in various formats across multiple media sources. Like traditional DBMS, an MM-DBMS provides integration, data independence, concurrency control, persistence, privacy, integrity control, and recovery. Additionally, an MM-DBMS can uniformly query different data formats, simultaneously query across media sources, retrieve media smoothly, and develop presentations from query answers that satisfy quality of service requirements. Multimedia databases support applications like video on demand, medical information systems, and public protection systems, but consume more storage and processing than traditional databases. Current research focuses on high performance and fast partitioning of compressed and uncompressed video.Database administrator

A database management system (DBMS) is a software application that allows users to store, organize, and manage large amounts of data in a structured and efficient manner. DBMS provides a centralized repository for data that can be accessed and manipulated by multiple users and applications simultaneously.
The primary functions of a DBMS include data storage, data retrieval, data security, and data integrity. DBMS allows users to define, create, and manipulate data using a variety of tools and interfaces, such as SQL queries, forms, and reports.
DBMS typically include features such as transaction management, concurrency control, backup and recovery, and query optimization to ensure the efficient and reliable operation of the system.
DBMS can be categorized into different types based on their architecture, such as relational, object-oriented, and NoSQL. Each type of DBMS has its own strengths and weaknesses, and the choice of DBMS depends on the specific requirements of the application.
Overall, a DBMS plays a critical role in managing large and complex data sets, and it is an essential tool for organizations that need to store, access, and analyze large volumes of data efficiently and effectively.ORDBMS

This document provides an overview of different database management systems:
- It defines a database and DBMS, and describes their basic functions.
- It explains the features of a relational database including tables, rows, columns, primary keys and relationships.
- It describes object-oriented databases, including object identity, classes, inheritance and encapsulation.
- It discusses object-relational databases as putting an object-oriented front end on a relational database.
- It briefly covers advantages and disadvantages of relational, object-oriented and object-relational databases.object database conceptual design.pptx

The document discusses different database models, focusing on object databases. It defines an object database as one based on the object model that stores data in the form of objects comprising data and functions. Object databases work well with object-oriented programming languages and principles like encapsulation and inheritance by supporting a flexible data model. However, object databases also have disadvantages like limited adoption, complexity in design and implementation, and challenges integrating with other systems.DBMS topic in PU

- 3. HIERARCHICAL DATABASE A DBMS is said to be hierarchical if the relationships among data in the database are established in such a way that one data item is present as the subordinate of another one.油 Here油subordinate油means油that油items油have油'parent- child'油relationships油among油them.油Direct油relationships油 exist油between油any油two油records油that油are油stored油 consecutively.油The油data油structure油"tree"油is油followed油 by油the油DBMS油to油structure油the油database.油No油backward油 movement油is油possible/allowed油in油the油hierarchical油 database.
- 4. NETWORK DATABASE A DBMS is said to be a Network DBMS if the relationships among data in the database are of type many-to-many.油 The油relationships油among油many-to-many油appears油in油 the油form油of油a油network.油Thus油the油structure油of油 a油network油database油is油extremely油complicated油 because油of油these油many-to-many油relationships油in油 which油one油record油can油be油used油as油a油key油of油the油entire油 database.油A油network油database油is油structured油in油the油 form油of油a油graph油that油is油also油a油data油structure.
- 5. RELATIONAL DATABASE A DBMS is said to be a Relational DBMS or RDBMS if the database relationships are treated in the form of a table.油there油are油three油keys油on油relational油DBMS油 1)relation油2)domain油3)attributes.油 A network means it contains fundamentel constructs sets or records.sets contains one to many relationship,records contains fields statical table that is composed of rows and columns is used to organize the database and its structure and is actually a two dimension array in the computer memory. A number of RDBMSs are available, some popular examples are Oracle, Sybase, Ingress,Informix, Microsoft SQL Server, and Microsoft Access.
- 6. OBJECT-ORIENTED DATABASE Object-oriented databases use small, reusable chunks of software called objects. The objects themselves are stored in the object-oriented database. Each object consists of two elements: 1) a piece of data (e.g., sound, video, text, or graphics), and 2) the instructions, or software programs called methods, for what to do with the data. Object-oriented databases have two disadvantages. First, they are more costly to develop. Second, most organizations are reluctant to abandon or convert from those databases that they have already invested money in developing and implementing. However, the benefits to object-oriented databases are compelling. The ability to mix and match reusable objects provides incredible multimedia capability.
