Change Data Capture (CDC) refers to a set of techniques used to identify and capture changes made to data in a database. This skill involves monitoring and recording insertions, updates, and deletions to ensure that data remains consistent across different systems. Knowledge of Change Data Capture (CDC) is utilized to facilitate data synchronization, enable real-time analytics, and support data warehousing by providing a reliable mechanism for tracking changes without requiring full data refreshes.

Denormalization refers to the process of intentionally introducing redundancy into a database by merging tables or adding duplicate data to improve query performance. This skill encompasses understanding data structures and relationships to optimize read operations, often at the expense of write efficiency. Knowledge of Denormalization is used to enhance data retrieval speed in applications where performance is critical, such as reporting and analytics, by reducing the complexity of joins and improving access times.

Erwin (Data Modeling Software) refers to a tool used for designing, visualizing, and managing data models within databases. This skill encompasses the ability to create entity-relationship diagrams, define data structures, and establish relationships between data elements. Knowledge of Erwin (Data Modeling Software) is utilized to ensure data integrity, optimize database performance, and facilitate effective data governance by providing a clear representation of data architecture.

Informatica is a specialized software skill that involves the use of a data integration platform for extracting, transforming, and loading data into various systems. It is used to manage and manipulate large amounts of data across different sources and formats, making it easier for organizations to analyze and use their data. Informatica skills are essential for data analysts, data engineers, and other professionals who work with large datasets.
