DB2 Database Management

DB2 is a database product from IBM. It is a Relational Database Management System (RDBMS). DB2 is designed to store, analyze and retrieve the data efficiently. DB2 product is extended with the support of Object-Oriented features and non-relational structures with XML.

History : Initially, IBM had developed DB2 product for their specific platform. Since year 1990, it decided to develop a Universal Database (UDB) DB2 Server, which can run on any authoritative operating systems such as Linux, UNIX, and Windows.

Data server editions and features

Depending upon the requirement of needful features of DB2, the organizations select appropriate DB2 version. The following table shows DB2 server editions and their features:

 

  • Advanced Enterprise Server Edition and Enterprise Server Edition (AESE / ESE) : It is designed for mid-size to large-size business organizations. Platform - Linux, UNIX, and Windows. Table partitioning High Availability Disaster Recovery (HARD) Materialized Query Table (MQTs) Multidimensional Clustering (MDC) Connection concentrator Pure XML Backup compression Homogeneous Federations
  • Workgroup Server Edition (WSE) : It is designed for Workgroup or mid-size business organizations. Using this WSE you can work with - High Availability Disaster Recovery (HARD) Online Reorganization Pure XML Web Service Federation support DB2 Homogeneous Federations Homogeneous SQL replication Backup compression
  • Express -C : It provides all the capabilities of DB2 at zero charge. It can run on any physical or virtual systems with any size of configuration.
  • Express Edition : It is designed for entry level and mid-size business organizations. It is full featured DB2 data server. It offers only limited services. This Edition comes with - Web Service Federations DB2 homogeneous federations Homogeneous SQL Replications Backup compression
  • Enterprise Developer Edition : It offers only single application developer. It is useful to design, build and prototype the applications for deployment on any of the IBM server. The software cannot be used for developing applications.

MongoDB Database Management

MongoDB is an open source document store NoSQL DBMS designed to make it easier for organizations to develop and run applications that address performance, availability and scalability, and support a variety of data types.

MongoDB's document data model lets developers easily store and combine data of any structure, without sacrificing data access or indexing functionality. This enables database administrators to dynamically modify the schema with no downtime.

MongoDB features

MongoDB 3.2, released in November 2015, introduces several new features, including pluggable storage engines. The in-memory storage engine enables all data to be maintained in-memory, while the ephemeral for-test storage engine is ideal for testing purposes but is not recommended for production implementation. This engine can be set up so that no data is maintained on-disk, which means no clean-up is needed in between test runs. Additionally, the WiredTiger storage engine, which delivers compression and document-level concurrency control, is now the default MongoDB storage engine. With MongoDB 3.2, encryption is also available for the WiredTiger storage engine in MongoDB Enterprise.

MongoDB 3.2 also delivers improved text search and shared cluster configuration, as well as the ability to validate documents during updates and inserts. The new partial index capability enables database administrators to create indexes using a filter that will reduce the size of the index and, in some cases, deliver performance improvements. Other highlights include enhanced real-time analytics, connectivity to industry-standard business intelligence and SQL query tools, schema discovery and visualization capabilities, as well as improved performance and availability.

The major components in the MongoDB package are mongod, the core database process; mongos the controller and query router for sharded clusters; and mongo the interactive MongoDB Shell, which is used to issue commands.

Applications connect to the database via the MongoDB database drivers. There are 12 supported drivers and more than 30 community drivers designed to conform to the style of the native programming language being used by the developer.

Additionally, multiple tools are packaged with MongoDB NoSQL DBMS for importing and exporting data from the database and for performing diagnostics. Ops Manager, provided as part of MongoDB Enterprise Advanced, can be used to provision, monitor, back up and scale MongoDB.

The Cloud Manager provides a cloud-managed MongoDB service on the user's infrastructure. For more information, download the MongoDB Architecture Guide.

As noted above, MongoDB has both an open source and commercial edition. The commercial edition, MongoDB Enterprise Server, is available as part of the MongoDB Enterprise Advanced subscription, which adds advanced security, administration features, support and on-demand training not available in the open source edition.
