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

DATABASE SECURITY Abstract: Security of database systems has become very important Now-a-days. As many of the operations now-a-days depend on the database systems, security became a problem because of increase in the number of web applications. If the data is affected in an application, it not only affects that single application but it affects the entire applications present in that system. Data may be damaged not only from the outside damages but may be also from inside damages. Hence, we are using

Client requirements presented to us were very high but at the same time well documented and mostly attainable. To achieve requested results, a web application based on ASP.Net with a relational database of repair cases had been proposed. Our initial language choice was Visual Basic .Net with SQL Express database server. Team functionality As a team we were able to work together very efficiently, as every team member has specific strengths. Good project documentation, good communication and confidence

1.2. Differential Privacy to the rescue. Privacy is a major problem these days. Cheaper memory has led to immense amount of data continuously being accumulated in various databases across the world, from universities, companies to patient records, content and link graphs of social net-works, mobility traces in cellular networks, book and movie ratings, etc.—and there are many socially valuable uses to which it can potentially be put. But, as Netflix and others have discovered, even when data

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

Monitoring your database is essential for recognizing unauthorized activities and stomping out performance issues the moment they arise. Accordingly, regular and consistent database auditing is essential for the good health and utmost performance of your system - ensuring zero-to-minimal downtime. That is why Crunchy Data provides the technology and expertise necessary to design, deploy and support PostgreSQL monitoring and alerting solutions for enterprise PostgreSQL database environments - whether

different ways, such as in Watson, Big Data becomes very interesting.”Tools that are used to nalyse the big data such as Google BigTable ,Hadoop and MapReduce that revolutionized the organizations has been discussed. Parallel and distributing computing model and the importance of 7 V’s (volume, velocity, veracity, validity, variety, volatility, variety) in finding the true value of Big data has been discussed • What are the 7 v’s mentioned in the paper?

A triplestore is a non-relational database that stores and retrieves triples using semantic queries. Triples store data and are imported and exported using the Resource Description Framework (RDF). A triple is a data entity comprising three components a subject, predicate and object that describe a set of data such as “We have shoes”. The subject is “We”, the predicate is “have” and the object is “shoes”. Triples provide an easy and flexible way of modeling data that is similar to how the human brain
