Answer:
Qualitative Data Analytics refers to a research method used to analyze non-numerical data to gain insights and understanding of human behavior, preferences, opinions, and experiences. Unlike quantitative data, which deals with measurable quantities and statistics, qualitative data focuses on the quality and characteristics of the data.
[/fusion_toggle][fusion_toggle title=”Question 62: Highlight the difference between Physical Backups and Logical Backups.” open=”no” class=”” id=””]
Answer:
The main difference between physical backups and logical backups lies in the way they capture and store data. Physical backups copy the raw binary data at the storage level, while logical backups capture data at a higher level, making it more flexible but potentially slower and less comprehensive. The choice between physical and logical backups depends on the specific backup and recovery requirements of the system.
[/fusion_toggle][fusion_toggle title=”Question 63: What are the different types of hierarchy?” open=”no” class=”” id=””]

There are two distinct types of hierarchies: the Default Hierarchy, which comprises dimension objects arranged in the class’s original order of presentation, and the Custom Hierarchy, formed by customizing the Default Hierarchy.
[/fusion_toggle][fusion_toggle title=”Question 64: What is dicing and sliding?” open=”no” class=”” id=””]
Answer:
Dicing and Sliding” are two fundamental operations in the context of Business Intelligence and data analysis. These operations are used to manipulate data and extract useful insights from large datasets.
- Dicing: Dicing involves breaking down or partitioning a dataset into smaller subsets based on specific criteria or dimensions. It is similar to “slicing” a dataset, but instead of selecting a single dimension, you can select multiple dimensions to create a multi-dimensional subset of the data.
- Sliding: Sliding, also known as “sliding window” or “time-based sliding,” is an operation where you create moving subsets of data by selecting a continuous range of values based on a specific dimension (usually time). It is often used for trend analysis or identifying patterns over time.
[/fusion_toggle][fusion_toggle title=”Question 65: What is Data Partitioning?” open=”no” class=”” id=””]
Answer:
Data partitioning is a technique used in database management and distributed computing systems to divide a large dataset into smaller, more manageable subsets called partitions. Each partition contains a portion of the overall data, making it easier to store, process, and retrieve information efficiently.
[/fusion_toggle][fusion_toggle title=”Question 66: What is a Repository?” open=”no” class=”” id=””]
Answer:
A repository refers to a centralized storage location or database where data related to BI activities is stored, managed, and organized.

[/fusion_toggle][fusion_toggle title=”Question 70: What is neutral network?” open=”no” class=”” id=””]
Answer:
A neural network is a type of artificial intelligence model inspired by the human brain’s neural structure. It is designed to recognize patterns and relationships in data and can be used for a variety of tasks, including image recognition, natural language processing, and prediction.
[/fusion_toggle][fusion_toggle title=”Question 71: List down the different types of Neutral Networks?” open=”no” class=”” id=””]
Answer:
There are several types of neural networks, such as:
- Feedforward Neural Networks: The simplest form of neural networks, where data flows in one direction, from input to output, without any feedback loops.
- Convolutional Neural Networks (CNN): Primarily used for image recognition and computer vision tasks. They use convolutional layers to automatically detect patterns and features in images.
- Recurrent Neural Networks (RNN): Suitable for sequential data, such as NLP, time series analysis, and speech recognition.
- Long Short-Term Memory Networks (LSTM): A specialized type of RNN designed to overcome the vanishing gradient problem and better capture long-term dependencies in sequences.
- Generative Adversarial Networks (GAN): A type of neural network architecture that consists of two networks, a generator, and a discriminator, which are trained together to generate realistic data, such as images or text.

[/fusion_toggle][fusion_toggle title=”Question 74: What is the main objective of a BI system?” open=”no” class=”” id=””]
Answer:
The main objective of a Business Intelligence (BI) system is to gather, store, analyze, and present business data in a meaningful and actionable way to support decision-making processes. BI systems are designed to provide valuable insights into an organization’s performance, operations, and trends, allowing businesses to make informed decisions and gain a competitive edge in their respective industries.
[/fusion_toggle][fusion_toggle title=”Question 75: Difference between BRD and SRS in Business Analysis” open=”no” class=”” id=””]
Answer:
The key difference between BRD and SRS lies in their level of detail and target audience. The BRD provides an overview of business needs and objectives, while the SRS provides a comprehensive blueprint for developers to build the software based on the business requirements. These two documents complement each other in the business analysis process, ensuring that the project stays aligned with the business goals and is successfully executed.
