JNTU B.Tech IV DATA ANALYTICS Previous Question Paper (July - 2023 - R16)

The core elements of data architecture include:

• Data Strategy: Defining the vision and alignment with business goals.
• Data Governance: Establishing policies, standards, and security protocols for data management.
• Data Integration: The processes and tools used to combine data from disparate sources.
• Data Modeling: Creating conceptual, logical, and physical representations of data structures.
• Data Storage and Infrastructure: The selection of databases, data warehouses, or data lakes to house information.

Primary data is considered more reliable than secondary data. This is because primary data is collected directly by the researcher for a specific purpose, ensuring that the methodology, data quality, and relevance are controlled and tailored to the current investigation.

In contrast, secondary data is collected by someone else for a different objective, which may lead to issues regarding outdated information, lack of context, or misalignment with the specific requirements of the current analysis. Since the origin and collection process of primary data are transparent and verified, it provides a higher level of accuracy and authenticity for decision-making.
