Materialized views : techniques, implementations, and applications by Ashish Gupta( Book )

10 editions published between 1998 and 1999 in English and Undetermined and held by 170 WorldCat member libraries worldwide

"When an application is built, an underlying data model is chosen to make that application effective. Frequently, other applications need the same data, only modeled differently. The solution of copying the underlying data and modeling is costly in terms of storage and makes data maintenance and evolution impossible. View mechanisms are a technique to model data differently for various applications without affecting the underlying format and structure of the data. The technique enables applications to customize shared data objects without affecting other applications that use the same objects. The growing data-manipulation needs of companies cannot be met by existing legacy systems that contain valuable data. Thus view mechanisms are becoming increasingly important as a way to model and use legacy data in new applications. Materialized views are views that have been computed and stored in databases. Because they reduce the need to recompute the view and/or data being queried, they speed up the querying of large amounts of data. Further, because they provide a systematic way to describe how to recompute the data, maintenance and evolution can be automated. Materialized views are especially useful in data warehousing, query optimization, integrity constraint maintenance, online analytical processing, and applications such as billing, banking, and retailing. This comprehensive volume, with a foreword by Jeff Ullman of Stanford University, will serve as a reference for students and commercial users, and encourage further use and development of materialized views."

Enterprise and organizational modeling and simulation : 7th International Workshop, EOMAS 2011, held at CAiSE 2011, London, UK, June 20-21, 2011 by Joseph Barjis( Book )

14 editions published between 2011 and 2013 in English and Undetermined and held by 19 WorldCat member libraries worldwide

This book constitutes the proceedings of the 9th International Workshop on Enterprise and Organizational Modeling and Simulation, EOMAS 2013, held in conjunction with CAiSE 2013 in Valencia, Spain, in June 2013. Tools and methods for modeling and simulation are widely used in enterprise engineering, organizational studies, and business process management. In monitoring and evaluating business processes and the interactions of actors in a realistic environment, modeling and simulation have proven to be both powerful, efficient, and economic, especially if complemented by animation and gaming elements. The ten contributions in this volume were carefully reviewed and selected from 22 submissions. They explore the above topics, address the underlying challenges, find and improve solutions, and show the application of modeling and simulation in the domains of enterprises, their organizations and underlying business processes
Partial information based integrity constraint checking by Ashish Gupta( Book )

3 editions published in 1994 in English and Undetermined and held by 7 WorldCat member libraries worldwide

"Integrity constraints are useful for specifying consistent states of a databse, especially in distributed database systems where data may be under the control of multiple database managers. Constraints need to be checked when the underlying database is updated. Integrity constraint checking in a distributed environment may involve a distributed transaction and the expenses associated with it: two phase commit protocols, distributed concurrency control, network communication costs, and multiple interface layers if the databases are heterogeneous. The information used for constraint checking may include the contents of base relations, constraint specifications, updates to the databases, schema restrictions, stored aggregates etc. We propose using only a subset of the information potentially available for constraint checking. Thus, only data that is local to a site may be used for constraint checking thus avoiding distributed transactions. The approach is useful also in centralized systems because relatively inexpensively accessible subsets may be used for constraint checking. We discuss constraint checking for the following three subsets of the afore mentioned information. Constraint Subsumption: How to check one constraint C using a set of other constraint specifications C and no data, and the knowledge that the constraints in set C hold in the database? Irrelevant Updates. How to check a constraint C using the database update, a set of other constraints C, and the knowledge that the constraints [C] [union of] C all hold before the update? Local Checking. How to check a constraint C using the database update, the contents of the updated relation, a set of other constraints C, and the knowledge that the constraints [C] [union of] C all hold before the update? Local checking is the main focus and the main contribution of this thesis."

The papers are organized in topical sections on design science; emerging themes; meta issues; methods; supporting business processes; team support; work-in-progress papers; and prototypes
Improvement to the PF algorithm by Ashish Gupta( Book )

2 editions published in 1993 in English and held by 6 WorldCat member libraries worldwide

Abstract: "The PF algorithm, discussed in [HD92], computes changes to a materialized view when the underlying base relations change. The algorithm considers each changed base relation in turn and propagates the changes to the derived relations. We propose ways of making this propagation process efficient by exploiting stratification [Ull89] of programs and by storing and reusing some of the information derived by the PF algorithm in [HD92]."

NakshaTweet - a mapping engine for trends in chatter in social media by Ashish Gupta( )

1 edition published in 2012 in English and held by 1 WorldCat member library worldwide

Today, we live in a social network generation. Yes a social network generation, which connect people from all over the world at all given time. The world is getting closer every second. Ever wondered how much people talk on these social networks sites in various parts of the world. If we can compare the intensity of this chatter for previous months, we can figure out when and where people are talking more as compared to other cities and time and know where something interesting is going on. In addition to these social networks, other thing that is taking over the world is a smart phone. Smart phone gives you a power of computer and Internet in the palm of your hand. It had been a prediction that by the end of year 2012, every 1 of 2 individuals in America will have a smart phone. These phone have taken the Internet and mobile services to a completely new level. It can be said that internet and wireless data services like 3G and 4G have opened a whole new world and have given the consumer a wider opportunity to gather information about the world in the shortest possible time. There are apps, which help you depict what is currently important going around you in your area using the power of REST API's. People tend to post about the things going around them, ups and down about new things and reviews and thought about the events in their area. These posts are relatively collected in a database on cloud and a consumer uses these updates to make his future plans. However, not everybody is socially active or spread his views. In cities where mobile data services are not so advanced, people are actually lacking the knowledge about the exciting things in their community as well as the about rest of the world. There is a need to find out in which cities people are talking more, posting things online, using the power of smart phone. This way we can able to depict a pattern of growing demands & needs of technology and social networking and also new events going around us. This pattern can benefit millions of consumers as well as commercial businesses to grow much further. As an example, if a new mobile company in the market is able to see a pattern about the cities where people are using less smart phone and social networking as compared to others, they can market their product more in these areas. Thus leading to business growth. Similarly a consumer can find out about a pattern in his city about time where people ate chatting more, there might be a possibility of something big and interesting going on and try to gather more knowledge, Thus making the consumer more socially active and informative. This thesis, therefore, is an original and formal interesting investigation to find out these patterns, giving people an idea about how the world is changing around them and at what rate and making them more informative. The research takes into consideration developing application for Android smart phone (based on JAVA), which uses REST API's from the famous social network TWITTER and depict a pattern of tweets from every city in the world in a form of bar charts and line graphs
