hi i need answer for 4.1 4E database systems the complete book

Answer 1

The complete book ( DS:CB) , by hector Garcia-molica, Jeff ullman , and Jennifer widom. The second edition of this book was published on June 9, 2008. The gradiance contract with Pearson (Addison-Wesley+Prentice-hall) has terminated, and we have decided to turn gradiance in to a free service if you are an instructor who wants to use the system, start by creating an account for your self at www.gradiance. com/services not at the Pearson site.

Note: passwords are >=10 letters+digits, with at least one of each. Also, we cannot make an account be an instructor account for a book if the same account has registered as a student for a course using the same materials then, email your chosen login , with the book whose materials you want, to support @ gradiance. com we'll enable you to create a class using those materials.

New features:

1).. we begin with a discussion of relational design, rather then E/R design. There are a number of technical improvements to the discussion of functional and multivalued dependencies, including the use of "chase" algorithm to make inferences of dependencies.

2).. we have added coverage of high level design using UML.

3).. coverage of index selection and use of materialized view has been added .

4).. there Is new coverage of the database aspects of PHP.

5).. entity resolution is covered.

6).. material on peer-to-peer databases has been added, including an algorithm for distributed hashing.
