Q1. What is the primary disadvantage of the file-oriented approach to data processing?
a) Data redundancy
b) Data isolation
c) Program or data dependency
d) Difficulty in accessing data
Show Answer
Correct Answer: a) Data redundancy
Explanation: In a file-oriented approach, if a particular data is required by two different applications, it may be stored in two or more files, leading to data redundancy. This redundancy can cause inconsistencies and increase storage requirements. The file-oriented approach does not efficiently manage the relationships between data, making it difficult to maintain data integrity and consistency.
Q2. Which of the following is NOT a type of file organization?
a) Sequential
b) Indexed
c) Hierarchical
d) Relational
Show Answer
Correct Answer: d) Relational
Explanation: Relational is a type of database model, not a file organization method. File organization refers to the way data is stored and accessed in a file system. Common file organization methods include sequential, indexed, and hierarchical. These methods determine how data is stored, accessed, and managed within a file system.
Q3. What is the primary purpose of a Database Management System (DBMS)?
a) To eliminate data redundancy
b) To manage file organizations
c) To store data in files
d) To process data in real-time
Show Answer
Correct Answer: a) To eliminate data redundancy
Explanation: The primary purpose of a DBMS is to eliminate data redundancy by integrating related files and managing the relationships between data. This helps maintain data integrity and consistency, making it easier to access, update, and manage data within an organization.
Q4. Which of the following is a component of the data hierarchy?
a) Database
b) Record
c) File organization
d) File utility
Show Answer
Correct Answer: b) Record
Explanation: The data hierarchy refers to the systematic organization of data, often in a hierarchical form. Data organization involves characters, fields, records, files, and so on. A record is a group of related data values, representing a single instance of a set of fields in a table.
Q5. Which of the following is a type of file in a computer system?
a) Regular
b) Directory
c) Special
d) All of the above
Show Answer
Correct Answer: d) All of the above
Explanation: The types of files recognized by a computer system include regular, directory, and special files. Regular files store data, directory files organize other files, and special files represent devices or other system resources.
Q6. What is the main difference between a file-oriented storage system and a transaction-oriented storage system?
a) File-oriented systems store data in files, while transaction-oriented systems store data in databases
b) File-oriented systems are more modern and efficient than transaction-oriented systems
c) Transaction-oriented systems allow for real-time processing, while file-oriented systems do not
d) File-oriented systems have more data redundancy than transaction-oriented systems
Show Answer
Correct Answer: a) File-oriented systems store data in files, while transaction-oriented systems store data in databases
Explanation: A file-oriented storage system creates files in sets as needed when a business sells products or services, with each file operating independently from other files in storage. In contrast, a transaction-oriented storage system, also known as a database storage system, maintains business information files in a more integrated and organized manner, allowing for better data management and reduced redundancy.
Q7. Which of the following is NOT a component of a relational database?
a) Table
b) Row
c) Field
d) File
Show Answer
Correct Answer: d) File
Explanation: A relational database is composed of multiple tables, with each table holding data in rows and columns. Rows, also known as records or tuples, represent groups of related data values. Columns, also known as fields or attributes, define the properties of the data stored in the table. Files are not a component of a relational database, as they are part of the data storage hierarchy outside the context of databases.
Q8. In a file processing system, what is the smallest allotment of logical secondary storage?
a) Bit
b) Byte
c) Field
d) File
Show Answer
Correct Answer: d) File
Explanation: In a file processing system, the smallest allotment of logical secondary storage is a file. A file is a collection of related information that is recorded on secondary storage. Files are used to store various documents and are grouped based on their categories.
Q9. Which of the following is a disadvantage of file-oriented data processing?
a) Data redundancy
b) Data isolation
c) Program or data dependency
d) All of the above
Show Answer
Correct Answer: d) All of the above
Explanation: File-oriented data processing has several disadvantages, including data redundancy, data isolation, and program or data dependency. Data redundancy occurs when the same data is stored in multiple files, leading to inconsistencies and increased storage requirements. Data isolation happens when data is scattered in different files, making it difficult to access and manage related data. Program or data dependency is a drawback where programs are dependent on the files and the files depend on the data, making it challenging to maintain and update the system.
Q10. What is the primary advantage of a database-oriented approach to data processing over a file-oriented approach?
a) Reduced data redundancy
b) Improved data isolation
c) Increased program or data dependency
d) Easier data access
Show Answer
Correct Answer: a) Reduced data redundancy
Explanation: The primary advantage of a database-oriented approach to data processing over a file-oriented approach is reduced data redundancy. By integrating related files and managing the relationships between data, a database-oriented approach helps maintain data integrity and consistency, making it easier to access, update, and manage data within an organization.
