In a tree-structured file, records are organized as
Step by step
Solved in 3 steps
- A movie file has the following record structure:name ofthe movie producer director type productioncostAssume that the name of the movie is the primary key of the file. Thefield type refers to the type of the movie, for example, drama, sci-fi, horror, crimethriller, comedy and so forth. Input a sample set of records of your choice into themovie file.i) Implement a primary index-based ISAM file organization.ii) Implement secondary indexes on director, type and productioncost.The program, word_frequency, counts the number of occurrences of words in a document. The program takes a filename as a parameter and performs the task. Get the program to run using the attached text file called document.txt. The file contains a piece of text. After you run the program and understand it's logic, modify word_frequency.py to use a binary search tree instead of a dictionary. Tasks: 1. Import a binary search tree 2. Change the filename in the program to reflect the change(s) made Python Only and no other coding languages. Import the module first before running it. Please show output when done. (build off of this file and try not to change too much) word_frequency.py: import sysfilename = sys.argv[1] freq = {}for piece in open(filename).read().lower().split():# only consider alphabetic characters within this pieceword = ''.join(c for c in piece if c.isalpha())if word: # require at least one alphabetic character freq[word] = 1 +…The___________ property stores an integer that represents the location of the record pointer in a dataset.a. BindingNavigator object’s Positionb. BindingSource object’s Position c. BindingSource object’s Locationd. TableAdapter object’s Location
- The program, word_frequency, counts the number of occurrences of words in a document. The program takes a filename as a parameter and performs the task.

Question 2 options: True False
- In Unix You have a record structured file named mydata that has four columns with default delimiter (white space). Sort the file based on its second column and redirect the file to a new file called sortedData.Write a program that generates student records in a database file.
