Fields

The database table will include the following fields:

• id bigint [pk]
• parent_id bigint [ref: > Parent.id]
• amount decimal(15,2)
• due_date date
• message varchar [ note: "optional"]

Let's break down each field to understand its role and importance in our payment system.

Understanding the Fields

Our database schema includes several key fields designed to capture comprehensive payment information. The id field serves as the primary key, ensuring unique identification of each payment record. The parent_id field establishes a crucial link to the Parent table, facilitating the retrieval of payment summaries for specific parents. The amount field stores the payment amount, utilizing a decimal type for accurate financial representation. The due_date field specifies the payment deadline, enabling timely tracking and management of payments. Finally, the message field provides an optional space for additional notes or details related to the payment.

id (bigint [pk])

The id field, defined as a bigint and designated as the primary key (pk), plays a pivotal role in our database design. This field ensures each payment record is uniquely identified, facilitating efficient data retrieval and management. By using a bigint, we accommodate a large number of payment records without risking overflow issues. The primary key constraint guarantees that no two payment records share the same id, maintaining data integrity and consistency within the database.

parent_id (bigint [ref: > Parent.id])

Linking payments to parents is crucial for providing personalized payment summaries. The parent_id field, a bigint with a foreign key referencing the id in the Parent table, achieves this. This relationship allows us to easily retrieve all payments associated with a specific parent, enabling the generation of accurate and relevant payment histories. By establishing this connection, we streamline data retrieval and enhance the user experience for parents seeking to monitor their payments.

amount (decimal(15,2))

Accurate representation of payment amounts is essential for financial integrity. The amount field, defined as a decimal(15,2), ensures we can store monetary values with precision. The decimal type prevents rounding errors that can occur with floating-point types, making it ideal for financial transactions. The (15,2) specification allows for up to 15 digits, with 2 digits after the decimal point, providing sufficient range and precision for payment amounts.

due_date (date)

The due_date field, of type date, plays a critical role in payment tracking and management. This field stores the date by which the payment is due, enabling automated reminders and efficient monitoring of overdue payments. By using the date type, we ensure consistency in date formatting and facilitate date-based queries and reporting. The due_date field is essential for maintaining timely payments and preventing financial discrepancies.

message (varchar [note: "optional"])

The message field, a varchar with an optional note, provides a flexible way to include additional information about a payment. This field allows for storing notes, descriptions, or any other relevant details that might be necessary for clarity or record-keeping. The optional nature of the field ensures that it doesn't impede the entry of essential payment data while providing a valuable space for supplementary information.

Acceptance Criteria

Here are the acceptance criteria for this repository:

• [x] We can create, update, read, and delete payment using the DB (POST, GET, PUT, DELETE)
• [x] Relations to other entities are properly set
• [x] Input validation for id, parent_id, and due_date

Let's dive into why each of these criteria is crucial for the success of our repository.

Detailed Acceptance Criteria

Our acceptance criteria cover the fundamental requirements for a robust and reliable payment database repository. These criteria ensure that we can perform all necessary operations on payment data, maintain proper relationships with other entities, and validate input to prevent errors. By meeting these criteria, we create a solid foundation for efficient and accurate payment management.

CRUD Operations (Create, Read, Update, Delete)

The ability to create, read, update, and delete (CRUD) payment records is fundamental to our repository's functionality. The POST operation allows us to add new payment records to the database. The GET operation enables us to retrieve payment information, whether it's a single record or a collection of records. The PUT operation facilitates updating existing payment records, and the DELETE operation allows us to remove records when necessary. Ensuring these operations function correctly is crucial for maintaining data integrity and enabling comprehensive payment management.

Proper Entity Relationships

Maintaining proper relationships with other entities, particularly the Parent entity, is essential for data consistency and efficient querying. The relationship between the Payment and Parent tables allows us to easily retrieve all payments associated with a specific parent. This relational integrity ensures that our data remains accurate and that we can perform complex queries involving multiple entities. By properly setting up these relationships, we streamline data retrieval and enhance the overall functionality of our repository.

Input Validation

Input validation is critical for preventing errors and ensuring data quality. Validating the id, parent_id, and due_date fields prevents the entry of incorrect or inconsistent data. For example, we need to ensure that the id and parent_id are valid integers and that the due_date is a valid date format. Implementing these validations safeguards our database against corrupt data and ensures that all records adhere to our defined schema. Robust input validation enhances the reliability and integrity of our payment data.
