As the project manager of the newly designed system for the oncology department, you are asked to provide a memo for the upcoming meeting with the chief executive officer (CEO) and a few senior managers. They are unaware of the features that have been designed and need a quick refresher prior to implementation. Therefore, you will provide and explain the details of the following:
- Explain the purpose of data analysis, data transformation, and visualization.
- Give an overview of business intelligence and a data warehouse.
- Explain the basics of building tables.
- Explain the use of pivot tables.
- Identify the database to be used.
- Explain the concept of functions and expressions.
The use of APA style is expected.

Introduction:
As a project manager of the newly designed system for the oncology department, it is essential to provide a memo that highlights the key features of the system to the CEO and senior managers. This memo will entail the purpose of data analysis, data transformation, and visualization, an overview of business intelligence and a data warehouse, the basics of building tables, the use of pivot tables, the database to be used, and the concept of functions and expressions. The memo will be written in APA style and will be 2-3 pages long.
Explain the purpose of data analysis, data transformation, and visualization.
Data analysis is the process of examining data sets to extract relevant insights and information. Data transformation is the process of converting data from its original form to a different one. Visualization, on the other hand, involves the use of graphical tools to represent data in a more understandable way. The purpose of data analysis, data transformation, and visualization is to gain a deeper understanding of the data and to derive insights that can be used to influence business decisions. The process can be used to identify trends, patterns, and relationships within the data, which can be used to improve business processes.
Give an overview of business intelligence and a data warehouse.
Business intelligence (BI) is a set of practices, technologies, and applications that are used to analyze, integrate, and present business information. A data warehouse, on the other hand, is a central repository where data from various sources is collected, analyzed, and stored. The purpose of a data warehouse is to provide a single, unified view of business data, which can be used for reporting, analysis, and decision-making. BI tools can be used to extract data from data warehouses, analyze it, and present it in a way that is easy to understand.
Explain the basics of building tables.
Tables are used to organize data in a structured manner. The basic steps involved in building tables include defining the columns and rows, choosing appropriate data types, and setting up constraints to ensure data integrity. Tables can be created using SQL or other database management tools, and can be used to store, manipulate, and retrieve data.
Explain the use of pivot tables.
Pivot tables are a powerful tool for data analysis and visualization. They allow users to summarize, analyze, and display large amounts of data in a way that is easy to understand. Pivot tables can be used to group data, calculate aggregates, and create visualizations. They are particularly useful when dealing with complex and large datasets, as they enable users to extract relevant information quickly and efficiently.
Identify the database to be used.
The database to be used for the oncology department system will be a relational database. Relational databases store data in tables, with each table representing a single type of object or entity. The database will be designed to meet the specific needs of the oncology department, with appropriate tables and fields defined to capture the relevant data.
Explain the concept of functions and expressions.
Functions and expressions are used to manipulate and transform data in a database. Functions are pre-defined procedures that perform a specific task, such as calculating the sum or average of a set of values. Expressions, on the other hand, are formulas that can be used to create calculated fields or to filter data. Functions and expressions are essential in data analysis and manipulation, and can be used to derive valuable insights from data.
Conclusion:
In conclusion, the oncology department system is a crucial project that requires a clear understanding of the key features. The memo has provided an overview of data analysis, data transformation, and visualization, business intelligence, and a data warehouse. We have also explained the basics of building tables, the use of pivot tables, the database to be used, and the concept of functions and expressions. It is our hope that this memo will provide the CEO and senior managers with the necessary information to understand the system before its implementation.
