• MySQL held only estimated of 0.2 percent of the $15 billion database market (measured in revenue).
• MySQL had a 33 percent market share measured in installed base, second only to Microsoft (78 percent ) and Oracle (55 percent), but ahead of IBM (22 percent)• Oracle, IBM, and Microsoft dominated this $15 billion market with mature products.• The three leveraged their brand, their integrated software stacks, and their service and partner networks to win in fierce competition.
• A relational database management system
(RDBMS) is a database management system (DBMS) that is based on the r el at i onal model. Most popular commercial and open source databases currently in use are based on the relational model.• ในการต้/ดต้�อก�บข้�อม�ลในฐานข้�อม�ลไม�ว�าจัะด�วย่การใช้�คื!าสั่��งในกล.�มดี�เอ�มแอล (DML ) หร�อ ดี�ดี�แอล (DDL ) หร�อจัะด�วย่โปรแกรมต้�างๆ ที่.กคื!าสั่��งที่��ใช้�กระที่!าก�บข้�อม�ลจัะถ�ก DBMSน!ามาแปล (คิอมไพล� )เป นการปฏิ/บ�ต้/การ (Operation ) ต้�างๆ ภัาย่ใต้�คื!าสั่��งน�1นๆ เพื่��อน!าไปกระที่!าก�บต้�วข้�อม�ลภัาย่ในฐานข้�อม�ลต้�อไป

• In October 2005, MySQL shipped its version 5.0.
• This new version, with the feature set comparable to those of Oracle, IBM, and Microsoft put MySQL in more direct competition with the big three.
• version 5.0 included stored procedures and triggers, functions which were explicitly outlined by Oracle. (SM–124A MySQL Open Source Database in 2004)
• BIT Data Type• Cursors• Information Schema• Instance Manager• Precision Math• Storage Engines• Strict Mode and Standard Error Handling• Triggers• VARCHAR Data Type• Views• XA Transactions• Performance enhancements
• However, in mid 2006, the product was still not certified by MySQL’s alliance partner SAP, the maker of the market leading enterprise resource planning (ERP ) software.• Despite added precision mathematics, tuning and scalability
properties, the functions were still insufficient to meet the database need of SAP’s applications, which, in two of threecases, ran on Oracle.
• Originally, MySQL had mainly one-time licensing revenues from its OEM business.• The OEM business was designed for customers who wanted to redistribute MySQL embedded into their own products.
• In early 2005, MySQL introduced the ”MySQL Network,” a support offer for end users, which Zack Urlocker, EVP of Products, described : ”The core MySQL database remains open source, but these services are only available to paying customers.”
• Mark Burton, EVP of Sales, commented : ”We’re following the Red Hat pattern. The subscription business is a growth business for us and that will, maybe even as early as the end of [2006], overtake our OEM business.”
• To offer scaled support services globally, MySQL listed many new partners including Hewlett-Packard, Novell, IBM, NEC, Unisys, Samsung, and hundred of smaller companies.
• However, as the company began charging for services, Mickos reported a change in expectations from their customers : ”For the first time we have customers that are complaining. When you have a five-star hotel and you charge virtually nothing, then nobody will complain. Now as we charge more, they also demand more and we pay even more attention to their requests.”
• In 2006, MySQL claimed to have 8 million active installations and 50,000 downloads per day, a 50 percent increase since 2004.
• And only one in 1,000 productive installations ended up as a MySQL customer paying for licenses or support.• In February 2006, MySQL closed a third round of funding from a venture capitalist and industry pundits Intel, Red Hat, and SAP.
• The company raised $18.5 million resulting in $30 million cash in the bank.• MySQL had inspired imitators. Highlighting the company’s success, many other open source database companies had also entered the market.
- In August 2004,
IBM had open sourced Cloudscape.
-Also in 2004,Computer Associates (CA) open sourced its Ingres database.
- In November 2004, Stanford-tied db4objects released db4o.
- In 2005, start-up EnterpriseDB announced PostgreSQL.
”Trying to kill MySQL by acquiring open source is like trying to kill a dolphin by drinking the ocean.” -Marten Mickos, CEO MySQL
• Not only Oracle but also IBM and Microsoft have each lowered their database prices and created aimed at smaller organizations and partners.• In October 2005, Oracle released a free low-end version, followed Microsoft, and Sybase.
• The purchase of open source companies was started by IBM in May 2005.• In October 2005, just when MySQL released version 5, Oracle announced the Finnish. • MySQL and its users feared that Oracle would discontinue InnoDB and thus seriously harm MySQL’s business.
• The leading transactional storage engine for the MySQL open source database . Innobase, a subsidiary of Or acl e, is a MySQL Enterprise Platinum partner .
• In February 2006, Oracle announced Sleepycat, and was expected to replace InnoDB.• In April 2006, Oracle becoming a MySQL partner.• Linux was an essential part of Oracle strategy to compete with Microsoft and IBM.• In September 2006, MySQL dropped support for Oracle’s Sleepycat products.
