Concurrency Control in Database Systems Key Points The purpose of concurrency control is to ensure that one user’s work does not inappropriately influence another user’s work. In some cases‚ these measures ensure that a user gets the same result when processing with other users as that person would have received if processing alone. In other cases‚ it means that the user’s work is influenced by other users but in an anticipated way. When many transactions take place at the same time‚ they are

Implementation of an Android-Based Disaster Management System By: Jovilyn Therese B. Fajardo and Carlos M. Oppus The Philippines is one of the most disaster prone countries in the world‚ and is constantly in the threat of some type of natural disaster. The article by Fajardo and Oppus describes how they were able to develop an android based application to save lives before‚ during‚ and after a disaster. A combination of several algorithms were used together to take information and determine

Dispute Systems Design Ury‚ Brett‚ and Goldberg pioneered Dispute Systems Design (DSD) in the 1980s‚ as a method for resolving intractable or frequent conflicts in troubled organizations‚ businesses‚ or entire industries. Their pioneering work was done at the Caney Creek Coal Mine‚ a mine that had been plagued by strikes in the 1970s.[4] At the center of their method were three heuristics for analyzing conflicts and designing new systems‚ which could deal with these conflicts quickly and efficiently

HISTORY OF DATABASE MANAGEMENT SYSTEM With the progress in technology in the areas of processors‚ computer memory‚ computer storage and computer networks‚ the sizes‚ capabilities‚ and performance of databases and their respective DBMSs have grown in orders of magnitudes. The development of database technology can be divided into three eras based on data model or structure: navigational‚ SQL/relational‚ and post-relational. The two main early navigational data models were the hierarchical model

SYSTEMS ANALYSIS AND DESIGN PROTOTYPING We know from the world of engineering that a manufacturer will develop a prototype model before mass producing the final product. So why not apply this concept to the development of a software product? This is what the pioneers of prototyping have set out to achieve by attempting to demonstrate how a system or a component of a computer-based information system will function in its environment. Users find such demonstrations very helpful in visualising
