Database approach
Database approach allows multiple users to access and share data at the same time. It ensures data consistency by allowing data to be updated in one place and automatically updating everywhere. It provides advantages like redundancy control, data security, data sharing, and improved backup and recovery. However, it also has disadvantages like high costs of the DBMS software, programming, and conversion. Users of a database include end users, top-to-bottom users like MIS, bottom-to-top users like organization leaders, and data administrators responsible for overall database functions and user training.
Database Management System
A database management system (DBMS) is a software system that is used to create and manage databases. It allows users to define, create, maintain and control access to the database. There are four main types of DBMS: hierarchical, network, relational and object-oriented. A DBMS provides advantages like improved data sharing, security and integration. It also enables better access to data and decision making. However, DBMS also have disadvantages such as increased costs, management complexity and the need to constantly maintain and upgrade the system.
Characteristics and Advantages of Database Management System
The document discusses the characteristics of database approaches and advantages of using database management systems (DBMS). It describes key characteristics like self-describing nature, support for multiple views, sharing of data, and persistence of data. The main advantages highlighted are improved data sharing, security, integration, consistency, and access. This leads to better decision making and increased user productivity. Some disadvantages discussed are increased costs, management complexity, need to maintain currency, and frequent upgrade cycles.
File based approach
File based Approach is a traditional approach of collecting and storing data.This presentation outlines what a file based approach is, its disadvantages and an alternative approach to it.

File system-and-database-chapter01-connoly
This document provides an introduction to databases. It discusses common uses of databases and limitations of file-based systems. A database is defined as a shared collection of logically related data designed to meet an organization's information needs. A Database Management System (DBMS) is software that enables users to define, create, maintain and control access to the database. Key components of a DBMS include hardware, software, data, procedures and people. The document outlines the history and advantages of DBMSs.
Advantages and disadvantages of relational databases
The document discusses the key characteristics of a relational database. It notes that a relational database organizes data into tables with rows and columns, and establishes relationships between tables using primary and foreign keys. This allows data to be non-repetitive and accurate. Users can query any table and combine related tables using joins to retrieve the required data. Relational databases also support data integrity, easy expansion to handle more data and changes, access control through user permissions, and flexible insertion, deletion and updating of records. However, performance may be impacted if there are many tables or complex joins, and extracting meaning from hierarchical data can be slower compared to hierarchical databases.
File systems versus a dbms
The document discusses traditional file systems and database management systems (DBMS). It provides an overview of traditional file systems, including their advantages and limitations. It then discusses DBMS, including its components, advantages like reduced data redundancy and improved data integrity, and limitations such as increased complexity. The document uses examples to illustrate key differences between traditional file systems and DBMS.
Chapter2
This document discusses database system concepts and architecture. It covers data models, schemas, and instances. There are three categories of data models: high-level conceptual models, low-level physical models, and representational models. Schemas describe the database design while instances represent the actual data. The three schema architecture separates the internal, conceptual, and external schemas. Database languages include DDL for design, DML for manipulation, and others. DBMSs provide various interfaces and operate in an environment alongside other software.

A database management system addresses these issues by allowing centralized data storage and shared access. Key topics covered include data modeling, the relational database model, database administration, popular DBMSs, and emerging concepts like data warehousing, data mining and business intelligence.

This study presents our experiences in designing, implementing and deploying an on-line evaluation scheme to measure the English and information technology skills of new entrants to Sri Lankan universities at point of entry in 2011. Over 15,000 students from 25 districts of the country were subjected to the on-line evaluation. The test was
conducted by using a learning management system, in 24 consecutive days in twenty six centres scattered across the country. This paper sums up the experiences we gathered in conducting the evaluation of a larger group of students spread across a wide geographical area and the lessons learned.

This document summarizes a study on improving student learning through assessment using social media and e-Learning 2.0 on a distance education degree program in Sri Lanka. Specifically:
- The study examines the Bachelor of Information Technology (BIT) program at the University of Colombo School of Computing, which has high failure and dropout rates.
- Currently exams focus on factual recall through multiple choice questions, encouraging rote learning. Language barriers also negatively impact some students' performance.
- The program aims to improve learning and reduce failure/dropout rates by designing new assessment methods using social media and e-Learning 2.0 to promote higher-order thinking. Data on student experiences will inform the redesign.

Speaker Search and Indexing for Multimedia Databases
This paper proposes an approach for indexing multimedia clips by speaker using audio segmentation, speaker recognition, and metadata indexing. Segmentation is done using Bayesian Information Criterion (BIC) and silence detection. Gaussian Mixture Models (GMMs) are trained for each speaker using Mel-Frequency Cepstral Coefficients (MFCC) as features. An ensemble of 3 GMMs is used to reduce errors from stochastic GMM training. Indexing utilizes sampled MFCC features from segments as metadata linked to speaker models. The system achieves a 20% true miss rate and 10% false alarm rate on segments 15-25 seconds, with performance decreasing for shorter segments.

Producing Employable Graduates
This document discusses how modern teaching methods focus on producing employable graduates through active learning. It provides the example of the University of Western Sydney, which identifies learning objectives before content to emphasize application skills. Their assessments evaluate continuous learning through practical work rather than only testing theoretical knowledge via exams. This process allows graduates to directly apply their skills in employment without additional training.
