Introduction to IBM DB2 Express-C

Free database that is useful even in small business

Easy-to-install virtual environmentDocumentation for self-study


6

IBM DB2 is one of the Big Three (by $ale$)1. Oracle (Many platforms, even mainframes)2. IBM DB2 (Many platforms, even mainframes)3. Microsoft SQL Server

MySQL (has most downloads and installations)


7

All big vendors have their free databases Can be used in real business without royalties Limitations to the free DBMS version:

Amount of RAM that can be used (1GB-4GB) Amount of disk space for the data (4GB- to unlimited) Number of processor cores used (1-2) Processor power units Number of simultaneos network connections Limited set of features Optimization and performance tuning features often

missing


8

All big vendors have their free databases Oracle 10g Express Edition

1 CPU, 1 GB RAM, 4GB Data

IBM DB2 9.5 Express-C 2 CPU, 2 GB RAM, Unlimited Data (IBM: ”Generous

offer”)

Microsoft SQL Server Express 1 physical CPU (multiple cores), 1 GB RAM, 4GB Data


9

Vendors buying each other – Volatile market Oracle bought InnoDB (The transaction capable

database motor used by MySQL) in 2005 IBM bought Finnish Solid in 2007 Sun bought MySQL (originally Swedish-Finnish) in

2008

What happens to LAMP? Can one put all eggs in one small basket (Small

databases)? Or commit to the Big Three?


10

What to look at when selecting a database? Performance Tools Connections Own platform Development tools and environment Support Own skills, training Price, Licences …


11

What to consider in a new DBMS? 1/2 …

Platform and installation Hardware including hard disks User accounts (E.g. Windows AD, Linux, DBMS

users) Terminology changed: Cluster, Server, Database,

Instance, Catalog, Schema (every product uses different terms for these. SQL-99 specifies standard names)


12

What to consider in a new DBMS? … 2/2

System roles and privileges, security features Registration, name services, listeners (Binding in Mainframes and batch runs) Connectivity and drivers Loading old data Integration to other systems SQL dialect is the smallest problem


13

Which one to select? All have their strenghts Oracle is widely used IBM DB2 spans from small systems to mainframes Microsoft SQL Server is optimized for Windows and

ADO.NET/ASP.NET applications MySQL is free and most popular in LAMP style

packages (But now own by Sun) PostgreSQL, open source db by community

… Big part of the commitment will be product dependent

16

Certification courses as part of the curriculum?


17

In Haaga-Helia Obligatory courses in the curriculum teach all
