Trace the flow of data through the data warehouse from beginning to end.Support your answer​

Answers

Answer 1

Explanation:

The flow of data through a data warehouse typically follows a specific process. Here is a general overview of the data flow from beginning to end:

1. Data Sources:

The data warehouse begins with various data sources, which can include transactional databases, external systems, flat files, APIs, or any other sources where relevant data is stored. These sources may be distributed across different departments or systems within an organization.

2. Data Extraction:

The first step is to extract the data from the different sources. This involves identifying the relevant data and retrieving it in a suitable format for further processing. Extraction methods may include direct database connections, data integration tools, or custom scripts.

3. Data Transformation:

Once the data is extracted, it goes through a series of transformations to make it suitable for analysis and storage in the data warehouse. This includes cleaning the data, removing duplicates, standardizing formats, aggregating values, applying business rules, and resolving inconsistencies.

4. Data Loading:

The transformed data is then loaded into the data warehouse. This step involves mapping the transformed data to the appropriate tables and columns within the data warehouse schema. Loading methods can vary, including bulk loading, incremental loading, or real-time streaming depending on the requirements and capabilities of the data warehouse.

5. Data Storage:

The loaded data is stored in the data warehouse, typically organized in a dimensional or star schema. The data warehouse employs optimized storage structures and indexing techniques to support efficient querying and analysis. This structured storage enables quick access and retrieval of data for reporting and analysis purposes.

6. Data Integration:

In addition to the primary data sources, the data warehouse may also integrate data from other internal or external systems. This integration process involves combining data from multiple sources to provide a unified view for analysis and reporting. Integration may include data from operational systems, external data providers, or third-party services.

7. Data Access and Analysis:

With the data stored in the data warehouse, users can access and analyze the data using various tools and techniques. This includes running ad-hoc queries, generating reports, creating dashboards, and performing advanced analytics. Business intelligence (BI) tools, reporting software, or custom-built applications are often used to facilitate data analysis and visualization.

8. Data Presentation:

The analyzed data is presented to end-users in a meaningful and understandable format. This can include interactive reports, visualizations, charts, graphs, or any other form that effectively communicates the insights derived from the data. The presentation layer may vary based on the needs and preferences of the intended audience.

Throughout this data flow, data quality and data governance play crucial roles. Data quality measures ensure the accuracy, consistency, completeness, and integrity of the data, while data governance practices enforce standards, policies, and security measures to maintain the reliability and confidentiality of the data in the data warehouse.

It's important to note that the specific details and technologies used in each step can vary depending on the organization, data warehouse architecture, and tools employed. The outlined flow provides a general overview of the typical data flow from beginning to end in a data warehouse environment.

Answers

The option that best describes the evolution of the strategic impact of analytics in the organization is "Reporting - Innovation."

Initially, analytics in organizations were primarily focused on reporting, which involved collecting and analyzing data to generate insights and reports on past performance. This tactical use of analytics provided organizations with a basic understanding of their operations and helped them make informed decisions based on historical data.

However, as analytics capabilities advanced and technology improved, organizations started leveraging analytics for more strategic purposes. This shift involved moving from a mere reporting function to using analytics for innovation. Instead of solely looking at historical data, organizations began using advanced analytics techniques, such as predictive analytics and machine learning, to gain insights into future trends, customer behavior, and market dynamics.

By embracing innovation through analytics, organizations gained a competitive advantage in the market. They were able to identify new business opportunities, optimize processes, personalize customer experiences, and make data-driven decisions that drove growth and profitability.

Therefore, the option "Reporting - Innovation" best captures the evolution of the strategic impact of analytics in the organization.

Write é CH general syntax for a polymorphic class​

Answers

A general syntax for a polymorphic class in C++ would be :

class ClassName : public BaseClassName {

public:

 // Member functions and variables

};

How to write the general syntax ?

When an object of a derived class is created, it can be used as an object of the base class. This is called polymorphism.

The ClassName class inherits from the BaseClassName class. This means that ClassName objects can be used in any context where a BaseClassName object is expected.

The public keyword specifies that the member functions and variables in the ClassName class are accessible to other classes.

Psychology professor Irvin D. Yalom has some interesting stories from his counseling experience with clients in individual and group therapy. One woman ranted at length in a group therapy session about her boss, who never listened and refused to pay her any respect. Theres nothing funny about a bad boss, but the interesting thing about this client was that as her work with Yalom continued, her complaints about her terrible boss persisted through three different jobs with three different supervisors. It is likely that not only she but also her supervisors, colleagues, and the companies where she worked suffered due to her unproductive relationships with her superiors.Contrast this womans attitude and approach to that of Marcia Reynolds who once worked for a micromanaging boss who was always criticizing and correcting her work. Reynolds decided to stop resenting his micromanaging and instead "act as though he were the worlds best boss with the worlds best employee." Instead of complaining and pushing back when her boss micromanaged, Reynolds was cheerful and helpful. She says an interesting thing happened: "When I stopped resisting, he started trusting me. When there was no longer any resistance, he quit fighting. Doing that really empowered me." As her boss increasingly trusted Reynolds, his micromanaging continued to abate, their relationship continued to improve, and both were happier and more productive. Reynolds was able to better do her job and get her subordinates what they needed by learning to manage up.QUESTIONSa. How did Marcia Reynolds manage or influence her boss?b.
