Chapter 1 – What is DB2 Express-C?

DB2 Express-C data server software ("DB2 Express-C") is a member of the IBM DB2

family of powerful data server software for managing both relational and XML data.

DB2

Express-C is a free, no-limits, and easy to use edition of DB2. The ‘C’ in DB2 Express-C

stands for the Community. A community of DB2 Express-C users that bands together to

assist each other, both online and offline. The DB2 Express-C community consists of all

sorts of people and companies who design, develop, deploy, or utilize database solutions.

Community members include:

 Application developers who require an open standards database software for

building standalone, client-server, web-based, and enterprise applications

 ISVs, hardware vendors, infrastructure stack vendors, and other types of solution

providers who want to bundle or embed a full-featured data server as part of their

solutions

 Consultants, database administrators, and IT architects who need a robust data

server for training, skills development, evaluation and prototyping

 Startups, small and medium-sized companies who need a reliable data server for

their applications and operations

 Database hobbyists and cutting-edge technology enthusiasts who want an easy to

use data server for building Web 2.0 and next generation applications

 Students, teachers, and other academic users who want a highly versatile data

server for teaching, courseware, projects and research

DB2 Express-C shares the same core functionality and code-base as the other priced

editions of DB2 on Linux, UNIX, and Windows. DB2 Express-C can be run on either 32-bit

or 64-bit systems with Linux or Windows operating systems. It is also available on Solaris

(x64) and as a beta on Mac OS X (x64). It can be run on systems with any amount of

processors and memory and does not have any specialized storage or system setup

requirements. DB2 Express-C also includes pureXML at no charge. pureXML is a

technology unique to DB2 that stores and processes XML documents natively.

20 Getting Started with DB2 Express-C

1.1 Free to develop, deploy, and distribute…no limits!

This sentence summarizes the key ideals behind DB2 Express-C:

 Free to develop: If you are an application developer and need a database for your

application, you can use DB2 Express-C.

 Free to deploy: If you are working in a production environment, and need a data

management system to store your vital records, you can use DB2 Express-C.

 Free to distribute: If you are developing an application or a tool that requires an

embedded data server, you can include DB2 Express-C. Even though DB2

Express-C is embedded in your application, and distributed every time you sell your

application, it is still free. You are required to register with IBM in order to re-

distribute DB2 Express-C; however this registration is also free of charge.

 No limits: While other competitor database offerings set limits on database sizes,

number of databases, and number of users, with DB2 Express-C there are NO data

size limits. Your database can continue to grow without violating the licensing

agreement. There are also no license imposed limits to the number of connections

or users per server.
