Compare the management issues associated with traditional data management and with big data management. Include data warehousing and Hadoop in your discussion. Also discuss the applications for these systems and future trends.
Management Issues in Traditional vs. Big Data Management
Traditional Data Management
- Focus: Primarily structured data (relational databases) with well-defined schemas.
- Volume: Relatively smaller datasets.
- Velocity: Data is typically collected and processed in batches.
- Variety: Limited to structured data (numbers, text, dates).
- Veracity: Data quality is generally higher due to controlled collection and storage.
- Management Issues:
- Scalability: Limited scalability to handle rapidly growing data volumes.
- Data Silos: Data often resides in isolated systems, hindering cross-functional analysis.
- Limited Flexibility: Difficulty in handling unstructured and semi-structured data.
- Slow Data Processing: Batch processing can lead to delays in insights.
Big Data Management
- Focus: Handles a wide variety of data types: structured, semi-structured (e.g., JSON, XML), and unstructured (text, images, videos).
- Volume: Deals with massive datasets that cannot be easily processed by traditional tools.
- Velocity: Handles data in real-time or near real-time, enabling rapid insights.
- Variety: Accommodates diverse data sources, including social media, sensor data, and IoT devices.
- Veracity: Data quality can be a significant challenge due to the diversity and volume of data.
- Management Issues:
- Data Integration: Integrating data from diverse sources can be complex and challenging.
- Data Quality: Ensuring data accuracy, completeness, and consistency is crucial but difficult to achieve at scale.
- Data Security and Privacy: Protecting sensitive data from unauthorized access and breaches is paramount.
- Skill Gap: Finding and retaining skilled professionals with expertise in big data technologies is challenging.
- Cost: Investing in the necessary infrastructure and tools for big data management can be expensive.
