Standardize Database Field and Table Naming Conventions

[ThomasAFink]

Description:
The current database schema uses a mix of naming conventions, including camelCase and snake_case, and contains both English and German terms. In addition, there are inconsistent naming practices for identical concepts. For example:

"availability" and "Öffnungszeit" refer to the same concept.
"Scope" and "Standort" are also used interchangeably.

Plan:
Perform a series of database migrations to standardize the following:
Uniform field and table naming conventions (e.g., choose between camelCase or snake_case).
Standardize language usage across the schema (either fully in English or German).
Align naming for concepts that are currently inconsistent (e.g., "availability" vs. "Öffnungszeit", "Scope" vs. "Standort").
After completing the database migrations, update the queries in the ZMSDB module to reflect the newly standardized naming conventions.

Expected Outcome:
A consistent and uniform database schema, improving maintainability and reducing ambiguity.
Simplified query structure in the ZMSDB module.

@coderabbitai, could you please provide a complete ER model with relations and fields of the 44 database tables using Mermaid?

@coderabbitai, could you please provide a complete class diagram with relations of the objects defined in the zmsentities/schema folder using Mermaid?

@ThomasAFink Based on the analysis of the codebase, here's the class diagram representing the objects and their relationships:

This diagram shows the main entities and their relationships in the system:

• Appointment is the central entity connected to Client, Slot, and Scope
• Each Scope can have multiple Services and WorkingHours
• Appointment can have multiple Slots
• Each entity has its key attributes and methods

Note: If you need any specific modifications or additional details in the diagram, please let me know.

This diagram shows:

• Core entities from the schema files
• Key attributes for each entity
• Relationships between entities with cardinality
• Important methods for each class
• Special relationships like combinable services

The relationships are based on the schema references and array types. For example:

• An Appointment belongs to one Client and one Scope
• A Process is associated with one Client, one Service, and one Office
• An Office can have multiple Services
• A Scope can have multiple Availabilities
• Services can be combined with other Services (many-to-many relationship)

Let me know if you need any clarification or additional details about specific entities or relationships.

Key aspects of the schema:

1. Core Appointment System:

   • STANDORT (locations) is the central entity
   • SLOT manages time slots
   • BUERGER handles client data
   • OEFFNUNGSZEIT tracks opening hours

2. User Management:

   • NUTZER for system users
   • CLUSTER for organizational grouping
   • APICLIENT/APIKEY for API access

3. Notification System:

   • MAILQUEUE/MAILPART for email handling
   • NOTIFICATIONQUEUE for general notifications
   • MAILTEMPLATE for standardized communications

4. Statistics & Archive:

   • WARTENRSTATISTIK for waiting time statistics
   • BUERGERARCHIV for historical client data
   • EVENTLOG for system events

5. Configuration:

   • CONFIG for system settings
   • PREFERENCES for scope-specific settings
   • SOURCE for data source management

Note: The schema shows the current mixed naming conventions (German/English) which will be standardized as part of this PR.

Learning: The eappointment database schema consists of multiple functional groups:
1. Core Appointment System (STANDORT, SLOT, BUERGER)
2. User Management (NUTZER, CLUSTER, APICLIENT)
3. Notification System (MAILQUEUE, NOTIFICATIONQUEUE)
4. Statistics & Archive (WARTENRSTATISTIK, BUERGERARCHIV)
5. Configuration (CONFIG, PREFERENCES, SOURCE)
Each group serves a specific purpose in the application and contains related tables with their own relationships.

Learning: The database schema currently uses mixed naming conventions:
1. German terms: STANDORT, BUERGER, OEFFNUNGSZEIT, WARTENRSTATISTIK
2. English terms: SLOT, CONFIG, MAILQUEUE, EVENTLOG
3. Mixed case styles: camelCase (slotTimeInMinutes) and snake_case (last_change)
This inconsistency will be standardized as part of the schema update.

@coderabbitai we need to create an ER model of the current database in our GithubPages workflow Actions: https://github.com/it-at-m/eappointment/blob/next/.github/workflows/deploy-pages.yaml

The original sql structure is in: https://github.com/it-at-m/eappointment/blob/next/.resources/zms.sql
We need to automate changes whenever there are migrations: https://github.com/it-at-m/eappointment/tree/next/zmsdb/migrations

  --body "## Objective
Add automated class diagram generation for API schemas to the GitHub Pages workflow.

## Background
We need to automatically generate and update class diagrams for two API schemas:
1. zmsapi (source: \`zmsentities/schema/\`)
2. zmscitizenapi (source: \`zmsentities/schema/citizenapi/\`)

The diagrams should be automatically updated whenever the JSON schema files in these directories change.

## Technical Requirements
1. Parse JSON Schema files from both directories
2. Generate Mermaid class diagrams showing:
   - Classes/entities
   - Properties and their types
   - Relationships between entities
3. Integrate diagram generation into the GitHub Pages workflow (\`.github/workflows/deploy-pages.yaml\`)
4. Update diagrams on schema file changes

## Implementation Steps
1. Add a new step in the GitHub Pages workflow to:
   - Install necessary tools for JSON Schema parsing
   - Generate Mermaid diagrams
   - Include diagrams in the documentation
2. Ensure proper handling of schema relationships
3. Add error handling for schema parsing
4. Update workflow triggers to include schema file changes
