Study Notes

Data Security and Encryption

Identify essential data elements requiring heightened security, encrypting only what is necessary.
Security and privacy requirements for big data align with those of conventional environments, with unique challenges present.

Interfaces and API Development

Interfaces allow bidirectional access to corporate applications and Internet data feeds.
APIs provide standardized methods for data access; API toolkits offer advantages over custom APIs.
Big data adoption necessitates new approaches to API development due to unstructured data from external sources.

Natural Language Processing (NLP)

NLP simplifies querying data by accepting natural language syntax over traditional languages like SQL.
Techniques such as connector factories introduce efficiency and abstraction, streamlining interface creation using XML.

Operational Databases

Core databases in big data environments must be fast, scalable, and reliable.
The effectiveness of a big data environment can vary depending on the chosen database engines or their mix.

Layered Security Infrastructure

User access to big data requires stringent security, only allowing legitimate business needs.
Application access through APIs typically protects against unauthorized usage.
An increase in data from mobile devices and social networks necessitates a multiperimeter security approach to manage threats.

Data Encryption Challenges

Data encryption remains a complex issue within big data due to system resource strain during encryption/decryption.
Traditional relational database systems may not be practical for all big data needs due to performance, scale, and cost limitations.

ACID Transaction Model

ACID defines the transactional behavior of databases:
- Atomicity: All parts of a transaction succeed or none do.
- Consistency: Only valid transactions are processed.
- Isolation: Simultaneous transactions do not interfere.
- Durability: Data permanence after a transaction.

Organizing Data Services and Tools

Organizing data services enhance data capture, validation, and assembly into relevant collections.
Tools in this ecosystem focus on integration, translation, normalization, and scalability to handle massive data volumes effectively.
