MySQL Workbench facilitates database design by providing a graphical interface. Users can visually create and modify database structures, making it easier to understand and manage the database schema. It also includes tools for running SQL queries, but its primary strength lies in visual design.

In SQL, the keyword used for aggregating data in a SELECT statement is SUM. It is used to calculate the sum of values in a particular column, providing a way to aggregate data and obtain meaningful insights from the dataset.

The Authorization model is designed to prevent unauthorized users from accessing or modifying data in a database. It involves defining and managing user privileges and permissions to ensure that only authorized users can perform specific actions on the database.

Data Marts typically have larger data volumes compared to the broader-scoped Data Warehouses. However, Data Marts have narrower specificity, focusing on a subset of data relevant to a specific business unit or department. This allows for more targeted and efficient analysis.

The process of decomposing a relation into smaller relations that meet normalization requirements is known as decomposition. It involves breaking down a table into smaller, more manageable tables to achieve higher normal forms and improve data integrity.

Dimension tables typically contain categorical data that provides context to the metrics in the fact table. Categorical data helps in categorizing and organizing information, allowing for meaningful analysis and reporting. Dimension tables are linked to the fact table through keys, creating a relationship between descriptive information and measurable metrics.

Query optimization is more challenging in a Snowflake Schema due to its normalized structure. The need for multiple joins between normalized tables can impact query performance compared to a Star Schema, where denormalization simplifies queries but may introduce redundancy.

Conflict resolution is a technique employed in collaborative data modeling to address conflicts that may arise when multiple users make changes to the same model simultaneously. It involves strategies such as merging changes, prioritizing modifications, or notifying users of conflicts.

Version control systems, such as Git, are crucial in managing changes during both Forward and Reverse Engineering to ensure consistency. They track modifications, provide a history of changes, and enable collaboration among team members, ensuring a reliable and traceable development process.

A check constraint in a database schema is used to validate data against a specified condition. It ensures that values in a column meet specific criteria, providing a way to control and maintain data integrity.
