db2 database highlights
Cross-platform unity
Through standardized SQL interfaces and data operation commands, "one development, multi-platform deployment" is achieved, reducing heterogeneous system migration costs.
Supports data sharding technology, allowing mainframe data to be seamlessly moved down to the LAN database server, realizing transparent interaction between the client/server architecture and host data.
High performance query engine
Intelligent query optimizer: The cost-based optimization strategy (Cost-Based Optimizer) dynamically generates execution plans, combines multi-dimensional statistical information (such as table size, index distribution) to select the optimal path, and is especially good at complex JOIN and subquery optimization.
Parallel processing capability: Supports multi-threaded parallel query (MPP), automatically splits tasks to multiple nodes in a distributed environment, and significantly improves the efficiency of processing large amounts of data.
Enterprise-level high-availability architecture
HADR (High Availability Disaster Recovery): Provides synchronous/asynchronous replication mode to ensure zero loss or near-real-time synchronization of data between the primary and secondary systems. The RPO (Recovery Point Objective) can be as low as seconds.
PureScale technology: achieves horizontal expansion through shared disk architecture, supports hundreds of node clusters, provides near-linear expansion throughput, and is suitable for high-concurrency scenarios such as financial transactions.
db2 database features
Cloud-native transformation: DB2 Warehouse on Cloud provides managed analysis services and supports Kubernetes containerized deployment and automatic elastic scaling.
AI fusion: Built-in machine learning libraries (such as IBM SPSS Modeler integration) enable direct calling of predictive models in SQL queries, simplifying the data analysis process.
Hybrid multi-cloud management: Unified management of DB2 instances across AWS, Azure, and private clouds through IBM Cloud Pak for Data, reducing the complexity of multi-cloud environment operation and maintenance.
db2 database functions
Object-oriented and complex data type support
Supports user-defined types (UDT) and functions (UDF), such as implementing geospatial data processing through the ST_Geometry type, or supporting semi-structured data through JSON/XML parsing functions.
Boolean matching and fuzzy search (such as SOUNDEX) functions optimize text retrieval and are suitable for legal documents, log analysis and other scenarios.
Multimedia and large object processing
BLOB/CLOB storage: supports single field storage of GB-level binary data (such as medical images, video streams), and combines streaming reading technology to avoid memory overflow.
Dedicated API: Provides DB2 multimedia expansion package (such as VideoCharger) to support value-added functions such as video transcoding and thumbnail generation.
Security and Compliance
Row-level access control (RLAC): restrict users to only access specific rows through conditional expressions, such as "WHERE department = USER_AUTH_ID()".
Transparent Data Encryption (TDE): Supports AES-256 encrypted storage, combines with IBM Guardium to implement dynamic data masking, and meets regulatory requirements such as GDPR and HIPAA.
Mixed workloads and distributed capabilities
Federated database: Seamlessly access heterogeneous data sources such as Oracle and SQL Server through WRAPPER technology, and support cross-system JOIN queries.
Q Replication: A log-based asynchronous replication tool that achieves cross-regional database synchronization with latency as low as milliseconds and is suitable for active-active architectures in disaster recovery centers.
