This article will help customers who is planning for new database or thinking to migrate. There are many databases available in market and customer's pain point is to choose right database as a long term solution in terms of reliability, stability, scalability, performance, high availability, easy support and cost.

In today's competitive market every one needs fast, quick and effortless solution without investing extra cost or low cost without impacting the quality.

There are various reasons why IBM DB2 is more suitable to business.

  • Common Code Base
  • Better  instance management
  • Improves Productivity through Integrated solution
  • SQL language compatibility
  • Perform Essential Maintenance and AutonomicsCapabilities
  • Save money through decreased storage requirements
  • Reduce application development and overall testing time.
  • Controls CPU usage through shares and limits
  • Easy Migration from other databases (Ex: Oracle, Mysql, Sybase etc.)
  • High availability and Zero data loss
  • Real-Time Data warehousing
  • 24*7 Support


Common Code Base

DB2 possesses a common code base across the supported platforms. It means when you run DB2 for LUW, you will find the same functionality across all platforms. It implies that applications that use DB2 on one platform can move to use DB2 in a different platform without any modifications.


Better instance management

DB2 supports multiple instances and multiple databases in each instance, No other databases have the capabilities to handle multiple instances and multiple databases in each instance without investing extra cost.

Due to multiple instance capabilities it is possible to set multiple environments (Development, SIT, UAT and Production ) without invest in extra h/w and s/w.


Improves Productivity through Integrated Business Solution

DB2 Simplifies promoting changes from development to test or test to production, Compare, synchronize, copy, clone, or merge database schema definitions from the source to the target and simplify the comparison of tables, Migrate objects from physical data models or from scripts Move objects and data with copy and paste, drag and drop, or directly from a comparison Make changes-in-place and manage live database connections.

Due to this integration Business can increase ability to meet SLA's and lower down the cost of design, development and administrations.

IBM Integrated Solution is a full data lifecycle management tool and used throughout deign till production implementation.

  • IBM Data Studio
  • InfoSphere Data Architect
  • InfoSphere Optim Performance Manager
  • InfoSphere Optim Query Workload Tuner
  • InfoSphere Optim Configuration Manager

IBM Data Studio :IBM Data Studio is Eclipse based framework free tool which helps database developers and administrators manage, administer, and develop heterogeneous database environments to increased productivity and collaboration. This tool also can be used to develop java based applications.

InfoSphere Data Architect : IBM InfoSphere Data Architectis an enterprise data modeling and integrated collaborative data design solution that business to discover, model, relate, standardize, and integrate diverse and distributed data assets. This tool helps forLogical modeling, Physical modeling, Transformation from Logical Modeling to Physical Modeling, Reverse engineering from database and DDL to physical model

InfoSphere Optim Performance Manager :InfoSphere Optim Performance Manager helps businesses improve database and application performance and reduce costs by providing DBAs and other IT staff the information needed to manage performance proactively, drill down the problem, setting up the critical health indicators and prevent problems before they impact the business.

Optim Query Workload Tuner : Optim Query Workload Tunercan use to capture, analyze queries, create detailed reports about queries get tuning, recommendations for those queries and to analyze and monitor query workloads that run on data servers.

InfoSphere Optim Configuration Manager:InfoSphere Optim Configuration Manager is a tool that Database Administrators can use to manage database client configurations, track configuration changes, view an auditable inventory of the data systems, and work with current and historical configuration data all from a central repository.


SQL language compatibility

Standard Query language is a backbone of database development. IBM DB2 SQLs are based on International Standards and compliance. Developer can write portable SQL's and reuse SQL's in any database or prepare and execute it on any application language like PHP, Java, .Net, C etc. due to quick and easy to understand because of their simple syntax, easy implementation and perform better due to close relationship with DB2 database systems.


Perform Essential Maintenance and Autonomicscapabilities

DB2 helps lower the cost of operations by making it easier for you to administer your database systems. DB2 features sophisticated controls for optimizing database performance so that database administrators can free to focus on higher value tasks and more productive.

DB2 autonomic computing environment is self-configuring, self-healing, self-optimizing, and self-protectingcharacteristics. By sensing and responding to changes in the environment, DB2's autonomic computing features automatically adjust the system to optimize its operations

Self-configurationof DB2 starts at the creation of a database. When DB2 database created automatically Configuration Advisor (CA) is started in the background to collect the environment characteristics. Based on the collected information, CA calculates optimal values for several database parameters like buffer pools, log buffers etc are adjusted  by providing an additional information such as number of concurrent applications, number of statements per transaction, workload type, and so on to make database run well

Self healingis able to generate alerts based on whether a health indicator exceeds a threshold or is in a non-normal state. In case of an alert, it sends notifications to the concern people by e-mails and corrective actions to be executed automatically.

Self managingcapabilities include automatic object maintenance and automatic storage management.

With automatic object maintenance Database administrators can automate the common maintenance tasks that include backups, reorganization of data in tables and indexes, and statistics collectiondatabase. Performing these tasks regularly on your databases is of extreme importance to ensure that they are optimized for performance and recoverability

With automatic storage management, DB2 will allocate storage on demand as the table consumption grows. No need to define the containers for table spaces but just specify a group of storage devices for DB2. DB2 creates the necessary containers automatically across the storage paths. This will help to manage automatic table space,automatic container and automatic resize of DMS table spaces.

Self-optimizationsimplifies the task of memory configuration. To optimize memory, DB2 offers the Self Tuning Memory Manager (STMM) handles instance and database memory related parameters like bufferpool, sort heap, lock list, package cache and total database memory used for database server.


Save money through decreased storage requirements

You can assign table spaces to the storage group as per data usage and classifications.

You can store highly required data i.e HOT data on fast storage where as other data on slower storage. This feature available at database end in the latest version of DB2 10 onwards called multi-temperature storage.

Now a day's storages cost is lower but managing and maintaining of data is more costly and painful.

DB2 can dramatically reduce that cost with industry leading data compression technologies which have the capabilities to provides comprehensive compression for almost every type of database object including table data, indexes, temporary tables, XML documents, log files and backup images including Catalog tables, Index objects, LOB objects, Auxiliary database files, Database meta-data and many more


Reduce application development and overall testing time

Business can achieve effortless development through implementation of db2 features like Time travel query, row & column access control, Multi-Temperature Data Management, Non relational RDF graph data

Time Travel Query

Time Travel Query makes your database time-aware and keeps a history of your data changes using temporal tables. You can travel to the past and query your data as it appeared at different points in time using standards-based support for temporal insert, update, and delete operations.  Competitor's database keeps history of deleted tables not any data change.

Row and column access control (RCAC)

DB2 provides critical enhancements to security and auditing by introducing row and column access control (RCAC) as a solution to secure data without any programming interfaces/trigger or any store procedure call. This enhancement helps; lower cost associated with the development and management of access control rules on business sensitive data with simple script including set of commands, Reduce time to value for business process applications without developing any extra application code and Query to show sensitive data (like Credit Card No, Account information, SSN-social security no., Employee salary, Annual Grading etc.)


Controls CPU usage through shares and limits

The DB2 workload manager is a built-in DB2 technology by which you can specifically allocate CPU resources to work that is being executed on a database server.

CPU resource entitlements can be controlled by using CPU shares and CPU limit attributes on DB2 WLM user and maintenance service class objects.

Using this feature you can take advantage of high priority jobs through CPU limit settings , Soft & Hard CPU sharing and better CPU utilization during peak and off-peak business hours.


Easy Migration from other databases (Ex: Oracle, Mysql, Sybase etc.)

DB2 provide native PL/SQL support in its core. Both PL/SQL and SQL PL produce the same virtual machine code for DB2's SQL Unified Runtime Engine. Therefore, by design, there is not difference for PL/SQL or SQL PL  code; both PL/SQL and SQL PL perform at the same speed and same performance level, on any platform either on Linux, Windows, AIX, Solaris due to DB2 common code capability.  

This migration is now just cut and paste database objects from competitor's database to DB2 like windows explorer. This is possible due to easy data studio plug-in called Database conversion workbench.


High availability and Zero data loss

IBM DB2 pureScale is now best industry standard servers and database technology that allows for building systems that provides a high level of performance, continuous availability (uninterrupted access to your data), application transparency to avoid the risk & cost of application changes, virtual scalability ( buy only what you need and add capacity as your needs grow).

The new improved high availability disaster recovery feature now allows up to three HADR standby databases. DB2 10 multiple standby setups improve ability to protect data while still keeping it highly available, all with a single technology.

Through this low cost features db2 easily managed planned/unplanned with minimum/zero data loss.


Real-Time Data warehousing

Faster and More accurate businesses decisions can be done through fast load and unload data techniques. Through this techniques business can achieve parallel processing, Minimal impact on availability, faster availability of data, Minimal impact on query performance and minimal downtime required for maintenance.


24*7 Supports

IBM has a three level of solution expert teams to resolve customer issues. Solution engineer's works world wide and customer need not to worry about their production issues due to single support number and customer support site.
