An organization chart where a high level manager has department managers with staff and non- managers without staff as direct reports would best be maintained in which of the following?

  1. A fixed level hierarchy
  2. A ragged hierarchy
  3. A reference file
  4. A taxonomy
  5. A data dictionary

Answer(s): B

Explanation:

A ragged hierarchy is an organizational structure where different branches of the hierarchy can have varying levels of depth. This means that not all branches have the same number of levels. In the given scenario, where a high-level manager has department managers with staff and non-managers without staff as direct reports, the hierarchy does not have a uniform depth across all branches. This kind of structure is best represented and maintained as a ragged hierarchy, which allows for flexibility in representing varying levels of managerial relationships and reporting structures.

Matching or candidate identification is the process called similarity analysis. One approach is called deterministic which relies on:

  1. Statistical techniques for assessing the probability that any pair of records represents the same entity
  2. Taking data samples and looking at results for a subset of the records
  3. Being able to determine the similarity between two data models
  4. Algorithms for parsing and standardization and on defined patterns and rules for determining similarity
  5. Finding two references that are linked with a single entity

Answer(s): D

Explanation:

Deterministic matching, also known as exact matching, relies on predefined rules and algorithms to parse and standardize data, ensuring that records are compared based on exact or standardized values. This approach uses defined patterns and rules to determine whether two records represent the same entity by matching key attributes exactly. Deterministic matching is precise and unambiguous, making it a common approach for high-certainty matching tasks, although it can be less flexible than probabilistic methods that allow for variations in data.

What statement is NOT correct as a key point of a MDM program?

  1. Must continually prove and promote its accomplishments and benefits
  2. Program funding requirements typically grow over time as the data inventory grows
  3. Has an indefinite life span
  4. Should be in scope for Big Data and loT initiatives
  5. Can be effectively created and managed long-term using the same methodology

Answer(s): E

Explanation:

A key point of a Master Data Management (MDM) program is that it must adapt and evolve over time. The statement that an MDM program "can be effectively created and managed long-term using the same methodology" is not correct. MDM programs must continually evolve to address new data sources, changing business requirements, and advancements in technology. As data inventory grows and the data landscape changes, MDM methodologies and strategies need to be reassessed and updated to remain effective. This adaptability is crucial for maintaining data quality and relevance.

Taxonomic Reference Data enable which of the following?

  1. Content classification and multi-level navigation to support Business Intelligence
  2. The use of canonical models
  3. Having data models physically instantiated in multiple platforms
  4. Key processing steps for MDMs
  5. Source systems named differently than target systems

Answer(s): A

Explanation:

Taxonomic reference data involves categorizing and organizing data to enable structured access and retrieval. It facilitates content classification, allowing for efficient multi-level navigation, which is essential for Business Intelligence (BI) activities. By organizing data into a taxonomy, users can easily locate and analyze information, supporting better decision-making processes in BI.
