MDM helps to define and manage the critical data of an organization to provide how many point(s) of reference
Correct Answer
A. Multiple
Explanation
MDM (Master Data Management) helps to define and manage the critical data of an organization to provide multiple points of reference. This means that MDM allows for the creation and management of a centralized and accurate source of data that can be accessed and used by multiple systems and applications within the organization. Having multiple points of reference ensures consistency and integrity of data across different systems, departments, and processes, enabling better decision-making and improving overall operational efficiency.
2.
In computing, MDM tool supports MDM by doing the following except
Correct Answer
C. Modifying data
Explanation
The MDM tool in computing supports MDM by standardizing data, incorporating rules to eliminate incorrect data from entering the system, and removing duplicates. However, it does not modify data. Modifying data would involve changing or altering the original data, which is not a function of an MDM tool.
3.
The following are the qualms found in MDM except
Correct Answer
A. Data security
Explanation
The given answer is "Data security". The question asks for the qualms found in MDM except for one option. The other three options, namely "Quality of data", "Data-reconciliation issues", and "Classification and identification of data" are all valid concerns or challenges that can be associated with Master Data Management (MDM). However, "Data security" is not typically considered a qualm or challenge in MDM, as it is a separate aspect that focuses on protecting data from unauthorized access, breaches, or misuse.
4.
Processes associated with MDM include the following except
Correct Answer
D. Data modification
Explanation
The question is asking for processes associated with MDM (Master Data Management) that are not included in the given options. MDM involves various processes such as normalization, data transformation, and data consolidation. However, data modification is not included in these processes. Data modification typically refers to the process of making changes or updates to existing data, which may not be directly associated with MDM.
5.
One of this is true about Normalization
Correct Answer
A. It helps to free the collection of relations from undesirable insertion, update and deletion dependencies
Explanation
Normalization is a process in database design that helps to eliminate undesirable dependencies between relations. These dependencies can occur when data is inserted, updated, or deleted, leading to inconsistencies and anomalies in the database. By normalizing the database, these dependencies are minimized, ensuring that data is stored in a structured and efficient manner. This helps to improve data integrity, reduce redundancy, and enhance overall database performance.
6.
Data federation is
Correct Answer
A. The process of providing a single virtual view of master data from one or more sources to one or more destination systems
Explanation
Data federation is the process of providing a single virtual view of master data from one or more sources to one or more destination systems. This means that instead of physically copying or integrating the data into a single system, data federation allows users to access and query the data from multiple sources as if it were stored in a single location. This approach is beneficial when dealing with large and distributed datasets, as it eliminates the need for data duplication and allows for real-time access to the most up-to-date information.
7.
One of the most common reasons some large corporations experience massive issues with MDM is
Correct Answer
D. Merger or Acquisition
Explanation
Large corporations often face challenges with their Master Data Management (MDM) due to the process of merger or acquisition. When two companies merge or one acquires another, they may have different systems, databases, and data structures. Integrating and consolidating these systems can be complex and time-consuming, leading to issues with MDM. The data from both companies needs to be synchronized and optimized to ensure consistency and accuracy. Therefore, merger or acquisition can be a common reason for massive issues with MDM in large corporations.
8.
The primary goal of data visualization is to
Correct Answer
A. Communicate information clearly and efficiently
Explanation
The primary goal of data visualization is to communicate information clearly and efficiently. Data visualization involves representing data in a visual format such as charts, graphs, or maps to make it easier for users to understand and interpret the data. By presenting data visually, complex information can be simplified and communicated in a way that is easier to comprehend. This helps in conveying the intended message effectively and allows users to gain insights from the data more efficiently.
9.
Under data reconciliation, redundancy can be linked to the following except
Correct Answer
A. Data filtering
Explanation
Data reconciliation is a process that involves comparing and correcting data from different sources to ensure consistency and accuracy. Redundancy refers to the presence of multiple sources or measurements for the same data. In this context, redundancy can be linked to sensor redundancy, observability, and degree of freedom, as they all involve having multiple sources of data. However, data filtering does not involve redundancy, as it is a process of removing or excluding certain data points based on specific criteria. Therefore, data filtering is the exception in this case.
10.
The process of copying master data from one system to another, typically through point-to-point interfaces in legacy systems is
Correct Answer
B. Data propagation
Explanation
Data propagation refers to the process of copying master data from one system to another using point-to-point interfaces in legacy systems. This involves transferring data from a source system to a target system, ensuring that the data is accurately replicated in the target system. This process helps in maintaining consistency and integrity of data across different systems and enables data sharing and integration between systems.
