隨著開(kāi)源數(shù)據(jù)庫(kù)產(chǎn)品的日趨成熟，加上IBM和MS最近也提供免費(fèi)的DB2和SQL Server版本，Oracle也將在年底前推出免費(fèi)的Oracle 10g Express Edition (Oracle Database XE)。
數(shù)據(jù)庫(kù)巨頭Oracle宣布將于年底推出一款免費(fèi)的Oracle 10g Express Edition，并于日前發(fā)布了Beta版。該免費(fèi)版針對(duì)學(xué)生，小型組織及需要把Oracle數(shù)據(jù)庫(kù)嵌入應(yīng)用程序的軟件供應(yīng)商。
該免費(fèi)版和Oracle其它數(shù)據(jù)庫(kù)產(chǎn)品在技術(shù)上是相同的，不過(guò)當(dāng)然存在許多功能上的限制，比如只支持單處理器，最大4GB存儲(chǔ)空間和最大1GB內(nèi)存。
Oracle服務(wù)器技術(shù)部高級(jí)副總裁Andrew Mendelsohn表示，該低端免費(fèi)版瞄準(zhǔn)的是免費(fèi)和開(kāi)源市場(chǎng)。
過(guò)去幾年中，開(kāi)源數(shù)據(jù)庫(kù)在企業(yè)用戶和Web開(kāi)發(fā)人員中的流行程度不斷提高。據(jù)統(tǒng)計(jì)，MySQL是目前開(kāi)發(fā)人員中最流行的開(kāi)源數(shù)據(jù)庫(kù)。針對(duì)這樣的情況，IBM 公司在本月早些時(shí)候隨一種PHP開(kāi)發(fā)包發(fā)布了DB2數(shù)據(jù)庫(kù)免費(fèi)版，而微軟也計(jì)劃在下月推出免費(fèi)的SQL Server 2005 Express。
Mendelsohn說(shuō)：“這個(gè)版本的發(fā)布是為了適應(yīng)低端市場(chǎng)的需求，我們希望低端用戶使用Oracle的產(chǎn)品而不是MySQL或SQL Server Express�！�

Oracle to offer free database

Oracle intends to release a free version of its database, a reaction to the growing competitive pressure from low-end open-source databases.
The database heavyweight on Tuesday is expected to announce the beta release of Oracle 10g Express Edition (Oracle Database XE), which will be generally available by the end of the year. It is targeted at students, small organizations and software vendors that could embed the Oracle database with an application.
The latest edition is the same as other databases in Oracle's lineup but is limited in usage. It can only run servers with one processor, with 4GB of disk space and 1GB of memory. Oracle on Friday offered a beta version of the new database for Windows and Linux on its Oracle Technology Network Web site.
The new low-end edition is aimed squarely at free and open-source alternatives to Oracle's namesake database, said Andrew Mendelsohn, senior vice president of Oracle's server technologies division.
Open-source databases have caught on steadily in popularity over the past few years with corporate customers and Web developers.
MySQL is the most popular open-source database among developers, according to a recent Evans Data study. IBM earlier this month released a free version of its own DB2 database as part of a PHP development package. And Microsoft intends to ship a free version of SQL Server 2005, called Express, next month.
"There is definitely a market there (for low-end databases) and a demand. And we want them to be using Oracle and not MySQL or SQL Server Express," Mendelsohn said. "It's definitely a reaction to the market interest."
About a year and a half ago, Oracle introduced Oracle 10g Standard Edition One, a version aimed at mid-size companies where Microsoft has many customers. That database is limited to two processors and cost $149 per user.
By introducing a free entry-level product, Oracle intends to get more developers and students familiar with its namesake database, Mendelsohn said. Those customers, Oracle hopes, will eventually upgrade to a higher-end version.
Previous Next "Even though the database is initially free, standards progress and those university students who are playing with the database today will eventually be working at corporations and making product decisions," he said. "We want to have mind-share with those people."
The Express Edition database can be distributed with other products. It will be available through Oracle's developer network and include a Web-based administration console development tools.
Separately, Mendelsohn offered comments on what Oracle intends to do with InnoDB, a storage engine for the MySQL database that Oracle acquired earlier this month.
He said Oracle intends to extend a contract with MySQL where the InnoDB storage engine is packaged with MySQL.
"There are all kinds of possibilities we're exploring," Mendelsohn said. "You might be seeing it showing up in Oracle products."
