What the benefit is of storing an index file that is separate from the file of records?
Homework Answers
Storing a files in a system with an index allows you to search a file very easily in any record. The indexes are unquiely allocated to the file. It reduces the search time and gives you the desired result. It is useful when large amount of data is present, we can easily and directly access that file with the help of index number.

Operating System Problem Three file allocation techniques for storing a file on disk, namely contiguous allocation, linked allocation, and indexed allocation. For each allocation method show how a file of 10 blocks would be allocated on disk. Note that the disk is represented as 30 blocks with blocks 0, 5, 6, 15, 25 already allocated. Note you must show the entire data structure for each allocation method as part of the answer. Thanks

1.What does a file index do? Why do we need a file index? 2.Modified All-Pairs Shortest Paths Problem This is the All-Pairs Shortest Paths problem with the following modification. Let n be the number of nodes in input graph. There are additional inputs k1, d in [1..n]. For every path that starts at, or ends at, or passes through node k1,distance d is added to the total distance of the path. Calculate shortest distances for all pairs of nodes (as in...

Assume that you have built a dense B+-tree index on SSN, and the B+-tree's leaf nodes contain record ids pointing to data records in data file. Assume 10-byte long. Assume also that you built the tree by using bulk loading so that the nodes at each level were filled up as much as possible. 4. a. b. How many levels does the resulting tree have? For each level of the tree, how many nodes are at that level? How many...

This is done in C++ Create an Employee class using a separate header file and implementation file. Review your UML class diagram for the attributes and behaviors The calculatePay() method should return 0.0f. The toString() method should return the attribute values ("state of the object"). Create an Hourly class using a separate header file and implementation file. The Hourly class needs to inherit from the Employee class The calculatePay() method should return the pay based on the number of hours...

in C++ Design a format for storing graphs in files. This will store your graph into a file with the following requirements: The first line will contain the number of Vertices. The second line will have a ‘U’ or a ‘D’ to tell the system if it is Undirected or Directed. The rest of the lines will be here for each of the edges. Each edge will contain three pieces of information: An integer containing the first Vertex An integer...

This program is used to create a phonebook for storing contact information into a text file. The program begins by asking the user to provide a name for the file that will contain their phone book information. It will then ask the user to provide the names and numbers of their contacts. It should keep asking the user for contact information until they type in Done (case-sensitive). After the user types Done, store all contact information into the file name...
