This document discusses databases and database management systems (DBMS). It defines a database as a collection of organized data and a DBMS as the collection of programs that allow users to access, manipulate, and represent data. The document outlines the architecture of DBMS including three levels of data abstraction. It describes hierarchical, network, and relational database models and notes that the relational model is most widely used. Advantages of DBMS include data sharing and consistency while disadvantages include costs and potential for failure. The document lists applications of databases such as banking, airlines, and universities.
This presentation provides an overview of different types of databases. It defines a database as an organized collection of related information. The main types discussed are flat file databases, relational databases, document-oriented databases, embedded databases, hypertext databases, operational databases, and distributed databases. Examples are provided for each type along with brief descriptions of their key features, advantages and disadvantages. Contact details are given at the end for the presenter's organization.
There are two types of distributed databases: homogeneous and heterogeneous. A homogeneous distributed database has all sites using identical software and appearing as a single system to users. It is easy to use and manage but slow. A heterogeneous distributed database can have different sites using varying schemas and software with limited cooperation. It allows huge data storage from different centers using various DBMSs but is difficult to manage and design.
A key feature of relational database applications is managing plural relationships—one-to-many and many-to-many—between entities. However, since it is often infeasible to adopt or develop a new database application for any given schema at hand, information workers instead turn to spreadsheets, which lend themselves poorly to schemas requiring multiple related entity sets. In this project, we propose to reduce the cost-usability gap between spreadsheets and tailor-made relational database applications by extending the spreadsheet paradigm to let the user establish relationships between rows in related worksheets as well as view and navigate the hierarchical cell structure that arises as a result. We present Related Worksheets, a spreadsheet-like prototype application, and evaluate it with a screencast-based user study on 36 Mechanical Turk workers. First-time users of our software were able to solve lookup-type query tasks with the same or higher accuracy as subjects using Microsoft Excel, in one case 40% faster on average.
This document discusses databases and provides information on different types of databases. It defines what a database is as a collection of interrelated data stored together to serve multiple applications. It then describes several common types of databases including relational databases, document oriented databases, embedded databases, graph databases, hypertext databases, operational databases, distributed databases, and flat files. For each type, it provides a brief definition and example. The document encourages learning more about programming through online courses offered by Baabtra.

RefWorks is an online tool that allows users to organize references, import references from various databases, and automatically generate citations and bibliographies. It collects and stores references in a personal online database. Users can access RefWorks through the library website or ATHENEA and register by filling out a registration form. References are imported into RefWorks after being searched for in information resources, and RefWorks can then be used to create bibliographies or format manuscripts with citations and references.
This document provides an overview of database management systems (DBMS). It discusses what a DBMS is, the main types of DBMS models including hierarchical, network and relational models, and the architecture of a DBMS including external, conceptual and internal levels. Advantages of DBMS include controlling redundancy, sharing data, data consistency and integration. Disadvantages include costs of hardware, software, staff training and potential for database damage. The document concludes that a DBMS allows users to create, read, update and delete database data consistently.

1. The document discusses different types of database management systems and data models including DBMS, RDBMS, file systems, and manual systems.
2. It provides brief definitions and examples of each type as well as their advantages and disadvantages.
3. The key database models covered are hierarchical, network, relational, and object-oriented models, with descriptions of their characteristics and how they have evolved over time.
This document provides an overview of key concepts in database management systems including:
1) It describes the DIKW pyramid which organizes data, information, knowledge, and wisdom.
2) It explains what a database is and the role of a database management system (DBMS) in handling data storage, retrieval, and updates.
3) It provides examples of database systems and languages used including structured query language (SQL) and its components for data definition, manipulation, and control.
The document discusses fundamental database concepts including transactions. A transaction is defined as an indivisible unit of data processing that must satisfy the ACID properties - Atomicity, Consistency, Isolation, and Durability. Atomicity means all changes in a transaction are committed, or if any part fails, then the entire transaction fails. Consistency requires transactions leave the database in a valid state without violating constraints. Isolation ensures concurrent transactions do not interfere with each other. Durability makes committed transaction changes persistent and not lost even in the event of failures.

MCQS on Brief History of Cinical Psychology.Bilal Anwaar
- The history of clinical psychology began with the founding of the first psychological clinic at the University of Pennsylvania in 1896 by Lightner Witmer.
- Important early figures included Freud, Piaget, Hippocrates, Plato, and Galen who studied mental illness and the brain.
- In the 18th-19th centuries, moral treatment movements led to more humane treatment of the mentally ill through asylums founded by Tuke and Pinel.
- Modern clinical psychology developed through standardized testing by Binet and Simon, Freud's psychoanalysis, and growth of psychological clinics and training programs around the world.

2. Presented by:
• Maryam Abdul Rehman
• Khadija Anwaar
• Kaynat Shahbaz
• Tooba Tanveer
• Syeda Fatima Abbas
3. Points to be discussed:
• What is database?
• What is DBMS?
• DBMS architecture.
• DBMS models.
• It's applications,advantages and disadvantages.
4. What Is DATABASE?
• Collection of related data (collection of
raw facts and figures related to objects).
• Information is not useful if not organized.
• In database, data are organized in a way
that people find meaningful and useful.
• For instance facebook.
5. DBMS:
• Collection of programs.
• It enables it’s users to access database, manipulate data and help in
representation of data.
• Controls access to database by various users.
• End-Users, Application Programmers, and Database Administrators
are they type of users who access a DBMS.
• For example: MYSQL is DBMS used by facebook.
6. • First implemented in 1960's.
• Charles Bachman's integrated data store(IDS) is said to be the first
DBMS in history.
• In 2014 Bachman was awarded the National Medal of Technology and
Innovation by President Barack Obama.
• Today DBMS's have revolutionized a lot .
DBMS:
7. Database architecture:
• The design of a DBMS depends on its architecture.
• There are mainly three levels of data abstraction:
• Internal Level or Actual PHYSICAL: Storage structure and access paths.
• Conceptual or Logical Level: Structure and constraints for the entire
database.
• External or View level: Describes various user views.
9. Hierarchical Model
• In a Hierarchical database,
model data is organized in a
tree-like structure
• Data is represented using a
parent-child relationship
• Each entity has one parent and
many children
• Old and not used now
Models of DBMS:
10. Models of DBMS:
Network Model
• Data is represented in the form
of graph
• The network database model
allows each child to have
multiple parents
• Entities can be accessed through
several paths
• Old and not used now
11. Relational model
• Data are organized in two
dimensional tables (relations).
• Tables are related to each other.
• This model is based on
normalizing data in the rows and
columns of the tables.
• Relational DBMS is the most
widely used DBMS model
because it is one of the easiest.
Models of DBMS:
12. Advantages
Advantages & Disadvantages:
Disadvantages
• Cost of hardware and software.
• Cost of staff training.
• Technical staff.
• Database failure.
• Control data redundancy.
• Data consistency.
• Data sharing.
• Less storage.
• Data security.
