Transaction Processing

Transaction processing is a computational style generally performed by server computers, which supports interactive applications (apps). Transaction processing is also known as information processing, which divides the work into indivisible and individual operations called transactions. The transaction is a set of tasks; a single task is considered as the minimum processing unit that cannot be divided again.

# Dependency Diagrams and Database Normalization

## 7. Book Royalty Dependency Diagram

The dependency diagram presented in Figure Q6.7 illustrates the financial relationship between authors and publishers in terms of royalties per book. The royalties can vary based on the author, the specific book, and the edition of the book. Below is a detailed explanation of the diagram:

**Figure Q6.7: Book Royalty Dependency Diagram**

- The diagram includes the following attributes:
- ISBN
- BookTitle
- Author_Num
- LastName
- Publisher
- Royalty
- Edition

- The lines between these attributes show dependencies, indicating how one attribute may determine another.

**Tasks:**
- a. Create a database in at least Second Normal Form (2NF), including a dependency diagram for each table.
- b. Develop a database in at least Third Normal Form (3NF), illustrating the dependency diagram for each table.

## 8. Prescription Dependency Diagram

Figure Q6.8 focuses on the healthcare domain, indicating how a patient can hold multiple prescriptions for one or more medications over time. The following is an explanation of the corresponding diagram:

**Figure Q6.8: Prescription Dependency Diagram**

- This diagram encompasses the following attributes:
- MedName
- PatientID
- Date
- RefillsAllowed
- PatientName
- Dosage
- ShelfLife

- The lines show the dependencies, illustrating which attributes are determined by others.

**Task:**
- Construct a database that reaches at least 2NF, with a detailed dependency diagram for each table.

These diagrams are pivotal in designing well-structured databases by eliminating redundancy and ensuring data integrity through normalization processes.

Organized collection of structured information, or data, typically stored in a computer system.

Relations describe the intersection between two axes, x and y. For example, a table (tuple) found in a database contains columns (attributes) and rows (records or observations). Database and Geospatial Mapping Application developers rely on tables and cartesian coordinate systems to adhere to the rules of relational database theory so that integrity in the location is preserved. Tables should only contain records that relate to the columns found in that table and the data domain determines what records should be stored in a given table. Database administrators can check for integrity in relationships within and between tables using structured query language (SQL). What other computer-science or IT jobs rely on relations?
T. Relational Model Instructions This assignment will show that you understand how columns should be separated between tables in a properly structured relational database. Your objective: Imagine you need to design a database that tracks members, type of membership, and exercise routines for each member. • Build a relational database model with multiple tables • Use your imagination and feel free to create the tables with as many columns as you would like. • Highest points will be awarded for completeness AND correctness.

Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality.
