Q.84 The geographical information system is capable of integrating _______ to capture, store, retrieve, analyse and display the spatial data.
- Aonly multi-sector and multi-level database systems
- Bonly multi-level and multi-period database systems
- Conly a multi-sector database system
- Dmulti-sector, multi-level and multi-period database systemsCorrect
Solution
Concept
GIS can integrate multi-sector, multi-level and multi-period databases for spatial data handling.
Step-by-step solution
1. GIS handles spatial data from many departments (multi-sector). 2. It handles data at different scales or administrative levels (multi-level). 3. It handles data from different time periods (multi-period). 4. So GIS integrates all three types of database. 5. Answer is (D).
Explanation
GIS is a system to capture, store, retrieve, analyse and display spatial data. It can combine data from many sectors, many levels and many time periods. So all three types together is correct.
Why the other options are wrong
A, B and C each use the word 'only' and leave out one or more database types, so they are incomplete.
Shortcut
In such GIS questions, the option that includes all types is usually correct.
Common mistake
Choosing a partial option and forgetting that GIS also handles time-series (multi-period) data.
Correct answer: D) multi-sector, multi-level and multi-period database systems
