| List-I | List-II |
| (A) Controlled Data Sharing | (I) Same data maintained in different places does not match |
| (B) Data Isolation | (II) Limited Access given to users |
| (C) Data Dependence | (III) There is no mapping between two files |
| (D) Data Inconsistency | (IV) If the structure of a file is changed, all the existing programs accessing that file also need to be changed |
The objective is to pair items from List-I with List-II, selecting from the provided options. Accurate matching requires a thorough understanding of the definitions and interrelationships of each term.
1. Controlled Data Sharing: This describes a scenario where access to specific data is restricted to authorized users to maintain data integrity and confidentiality. Consequently, it corresponds to the description: Limited Access given to users in List-II. Therefore, the correct match is (A) - (II).
2. Data Isolation: This condition arises when distinct data sets are not easily integrated or queried together due to a lack of interrelationship. It aligns with There is no mapping between two files from List-II. Thus, (B) - (III) is the correct match.
3. Data Dependence: This refers to situations where modifications to the data structure necessitate alterations in all application programs that access the data. This corresponds to If the structure of a file is changed, all the existing programs accessing that file also need to be changed in List-II. Hence, (C) - (IV) is the correct match.
4. Data Inconsistency: This occurs when identical data stored across different locations does not align, potentially due to inadequate updates or redundancy. This matches the description Same data maintained in different places does not match in List-II. Therefore, (D) - (I) is the correct match.
The resulting correct matches are: (A) - (II), (B) - (III), (C) - (IV), (D) - (I).
