Lambda Architecture

This pattern combines batch and stream processing to handle both historical and real-time data. A batch layer processes historical data for accuracy, while a speed layer processes real-time data for low-latency insights.

Kappa Architecture

A simplification of the Lambda architecture, the Kappa architecture relies solely on a single stream processing pipeline to handle both historical and real-time data, often by replaying historical data through the streaming system.

Data Lakehouse

This pattern combines the flexibility and cost-effectiveness of a data lake with the structure and governance of a data warehouse. It utilizes open formats (like Parquet or ORC) for data storage and provides transactional capabilities and schema enforcement, enabling both traditional BI and advanced analytics on the same data.

Data Structures

A data structure is a particular way of organizing and storing data in a computer's memory or storage so that it can be accessed and modified efficiently. They are fundamental building blocks in programming and algorithm design, dictating how data elements are related and the operations that can be performed on them.

Common types of data structures include:

• Linear Data Structures: Arrays, Linked Lists, Stacks, Queues. These structures arrange data in a sequential manner.

• Non-linear Data Structures: Trees, Graphs, Hash Tables, Heaps. These structures represent more complex relationships between data elements.

Data Formats

A data format, on the other hand, specifies the specific arrangement and encoding of data for storage or transmission, often in a file or network stream. It defines how data is represented at a lower level, typically down to the character or byte level, ensuring consistent interpretation across different systems or applications.

Common data formats include:

• Text-based formats: CSV (Comma Separated Values), JSON (JavaScript Object Notation), XML (Extensible Markup Language). These formats are human-readable and widely used for data exchange.
