For Organizations like Facebook and Google the web has developed has a vast, distributed data repository for which handling by conventional

Suggest a manner in which a database management system could suppress responses that reveal sensitive information without disclosing that the responses to certain queries are sensitive. It is every company mandatory requirement to make sure sensitive data is protected from public access at all times. In large organization sensitive information such as employee salary and performance should be kept confidential from most of the DBA users. For this DBMS uses database security and authorization subsystems

Relational Tables: The relation between numbers of tables in a database is called Relational tables. By using relational tables we can perform join operations on database tables and get optimized results which are required. Relational tables solve the joining of table’s problem by verifying the combination of primary and foreign key in the tables being joined. I used these relational tables in assignments like working with chinook database, where the queries are written for optimizing various results

Design of a Reconfigurable Hybrid Database System. “Disc Resident database systems (DRDBS)” are conventional databases systems in which data is permanently stored on discs. In “Main Memory Database Systems (MMDBS)”, the databases are stored onto the main memory. As the memory locations can be accessed directly using addresses, they allow very fast access to the data stored on them. They show better throughput in processing transactions and respond much more quickly than DRDBS. Because of the fast

The University Student Registration System: a Case Study in Building a High-Availability Distributed Application Using General Purpose Components M. C. Little, S. M. Wheater, D. B. Ingham, C. R. Snow, H. Whitfield and S. K. Shrivastava Department of Computing Science, Newcastle University, Newcastle upon Tyne, NE1 7RU, England. Abstract Prior to 1994, student registration at Newcastle University involved students being registered in a single place, where they would present a form which had

on database technology have been ever expanding since its introduction in the 1960’s. Today traffic on the internet requires that millions upon millions of records be stored and queried each second. Data must be highly available and quickly retrievable. These requirements put together have given rise to new forms of database technologies collectively called “NoSQL” or “Not Only SQL”. NoSQL eschews the strict guidelines that govern the creation and function of traditional relational databases. These

The Database Dilemma Personal privacy today is a controversial and complex topic, which is influenced by a number of factors. There is an integral role that databases play in this highly debated topic. The fact that many people now carry out their transactions electronically is another important factor. There is also pressure on personal privacy for increased national security around the world to combat terrorism. In addition, personal privacy is even threatened by commercial factors and the

THE ADVANTAGES OF USING DATABASES WITHIN BUSINESSES There are significant advantages to using databases in a business, especially in large companies. The main benefit of databases is that they save time. With the use of a simple queries, millions of records can be searches in a matter of seconds to give the information needed. Think about how long it would take to go through a million paper records held in files. Another great benefit is that the databases can be accessed by multiple users

unique. Accuracy can be assured when Zillow takes data from reliable authenticated sources (e.g. the land office), and timeliness can be assured with daily updates (or hourly where applicable). Consistency can be assured with a proper design of the database structure, and the presentation layer. Completeness and uniqueness could something be missed, as data completeness depends on the availability of the information provide by home owners to the land office, and some amount of attributes might be missing
