- 28. Traditional Data Mining vs Big Data Analysis Traditional Big Data analysis Memory access Data is stored in centralized RAM and can be efficiently scanned several times Data be stored on high distributed data sources In case of huge, continuous data streams, data is accessed only in single scan Computional processing and architectures Serial, centralized processing A single-computer platform that scales with better hardware is sufficient Parallel and distributed architectures may be necessary Cluster platforms that scale with several nodes may be necessary Data Types Data source is relatively homogeneous Data is static and of resonable size Data come from multiple data sources which may be heterogeneous and complex Data may be dynamic and evolving. Adapting to data changes may be necessary
- 29. Traditional Data Mining vs Big Data Analysis Traditional Big Data analysis Data management Data format is simple and fits in relational database or data warehouse Data access time is not critical Data format are usually diverse and may not fit in a relational database. Data may be greatly interconnected and needs to be integreted from several nodes Often special data systems are required that manage varied data formats (NoSQL, Databases, HADOOP,…) Data acess time is critical for scalability and speed Data quality The provenance and pre-processing steps are relatively well documented Strong correction techniques were applied Data is relatively well tagged and labeled The provenance and pre-processing steps may be unclear and undocumented There is a large amount of uncertainly and imprecision in the data Only small numer of data are tagged and labeled
- 30. Traditional Data Mining vs Big Data Analysis Traditional Big Data analysis Data processing Only batch learning is necessary Learning can be slow and off-line Data fits into memory All the data has some sort of utility Data may arrive in a stream and need processed continuously Learning need to be fast and online The scalability of algorithms is important Data not fit in memory
