Db2 for z/OS enables organizations to run mixed workloads with exceptional scalability, high performance and round-the-clock availability.īeing relational, the disadvantages common to the RDBMS type apply to Db2 as much as any other RDBMS.Db2 on LUW platforms offer an Oracle SQL compatibility option.Choice of deployment model includes on-premises, hosted cloud deployment or managed cloud deployment.AI and machine learning (ML) capabilities, including the augmented data explorer, deliver natural language query capabilities, a ML query optimizer, and a hybrid data management platform to enable seamless sharing of structured, unstructured and semistructured data.This enables organizations to store information relating to past, present and future time, as well as use time-travel queries to view past and future data states. A DBA can build a temporal database using Db2 to enable system and business changes to be captured, maintained and queried.Hybrid transaction analytical processing, or HTAP, performance is accelerated by the Db2 BLU column store with single instruction, multiple data, or SIMD, exploitation and data-skipping technology on LUW platforms and by the IBM Db2 Analytics Accelerator on z/OS.Many query predicates can be evaluated without having to decompress the data. Actionable compression can deliver storage space savings without sacrificing performance.What are the advantages of Db2?ĭb2 offers many advanced features for improving data and database management, including the following:
#Db2 universal database update#
Once created, a DBA or developer can use a Db2 database and its underlying structures to create, read, update and delete data to support an organization's business requirements. Db2 databases are created using Data Definition Language, or DDL, commands and are composed of tablespaces, tables with rows and columns, views, indexes, stored procedures and other supporting structures. The physical storage of data can be managed without affecting the access to logical storage structures.
The Db2 DBMS also prevents unauthorized access, provides utilities for backing up and recovering data and offers performance tools and data management capabilities.ĭb2 databases have logical structures and physical structures which the DBMS manages separately. The Db2 DBMS operates as the server to manage data in databases across a multiuser environment, enabling many concurrent users to access the same data simultaneously. A database is a large structured set of persistent data, and its purpose is to store, retrieve and manipulate related information.Ī database administrator ( DBA) uses Db2, which is DBMS or database server, to create and use Db2 databases. What is a Db2 database and how does it work?Ī Db2 database is a group of data treated collectively as a unit. In addition to being a relational DBMS, Db2 also offers integrated support for several NoSQL capabilities, including XML, graph store and JavaScript Object Notation, or JSON.
Used by organizations of all sizes, Db2 provides a data platform for both transactional and analytical operations, as well as continuous availability of data to keep transactional workflows and analytics operating efficiently. Db2 is a family of database management system (DBMS) products from IBM that serve several different operating system (OS) platforms.
