Tuple

technical details of each relations, for example, what is the tuple size of the relation, what are the total number of blocks allocated for each relation, what are the number of tuples per block and so on. The algorithm for the Join are detailed and explored. Also for the algorithm, the best, the worst case is being elaborated. Further, even the available memory size, allocated memory size, are taken into account while retrieving the tuples from the relations. The number of Block transfers, and number

The topic of my writing this week is words in The Giver that only the people in the community use. These words can sound like something but they really could mean the opposite of what you think. I am going to talk about what words mean and what effect they could have on the people in the community. My first word is release. In this word is sounds the same as it would to you and I. It also has the same meaning. But in some cases in our world release can be a good thing but in the community it is

Dynamic composition in distributed system or multi-agent system has long time been a hot field in research community. This report investigates some models and languages which have been developed in recent years and used to model multi-agent and distributed system. By comparing their advantages and drawbacks, some proposals are given for possible future research. Author Keywords Coordination language, Linda, GALS, SystemJ I. INTRODUCTION In recent years, with the popularity of service orientation

\bigskip In general, with the arrival of new data items, old items are evicted from the window. This implies queries over sliding window are monotonic in nature; when an input data expires from the window, all results that were generated from that tuple are removed from the answer. \subsection{Batch

for this type of data efficient processing of top-k queries is a crucial requirement. This paper describes fundamental characteristics including relational database, top-k queries, steiner trees. Recently, Tuple units are used to improve the keyword search by joining the multiple related tuple units and indexes are used for structural relationships. In this paper various existing techniques for developing search system are compared. This survey also describes the Ranking. Ranking queries are dominant

large number of valid tuples are not displayed to the user, these hidden databases are to be extracted. Introduction: The paper tries to provide a better technique to the user to query the database. There are many interfaces that hide their data from the users and allow them to access the database in a controlled manner i.e., when a query results in many number of tuples, not all tuples are displayed. While some interfaces also provide the user with the count of tuples which satisfies the search

Review Entity-Relationship Diagrams and the Relational Model CS 186, Fall 2007, Lecture 2 R & G, Chaps. 2&3 A relationship, I think, is like a shark, you know? It has to constantly move forward or it dies. And I think what we got on our hands is a dead shark. Woody Allen (from Annie Hall, 1979) • Why use a DBMS?

1. Introduction This paper mainly focuses on techniques for domain discovery over hidden databases. Basically, some sources of valuable information on the web are often hidden behind search interfaces. These are referred to as Hidden Web Databases. [3] Attribute domains are principles that describe the legal values of a field, giving a method for enforcing data integrity. They are used to constrain the values allowed in any particular attribute for a table or feature class. [2] This paper essentially
