------解決方案-------------------- Back in January we launched a survey of database users to explore the competitive dynamic between MySQL, NoSQL and NewSQL databases, and to to discover if MySQL usage is really declining – as had been indicated by the results of a prior survey.
The publication of the associated report took longer than expected, mostly because we expanded its scope to include revenue and growth estimates for the MySQL ecosystem, NoSQL and NewSQL sectors respectively, and with that report now published I am pleased to fulfil our promise to share the survey results.
We seem to be having some random embedding issues so for now the results can be found on SlideShare, adapted from the presentation given at OSBC earlier this week. For greater context, we have also included an explanation of each slide, below:
Slide 2: Provides an overview of the associated report – MySQL vs NoSQL and NewSQL 2011:2015, which is available here.
Slide 3: Explains why we launched the report. We once described as the crown jewel of the open source database world, since its focus on Web-based applications, its lightweight architecture and fast-read capabilities, and its brand differentiated it from all of the established database vendors and made for a potentially complementary acquisition. Today, the competitive situation is very different.
Slide 4: Oracle』s MySQL business faces competition from the rest of the MySQL ecosystem, as illustrated in Slide 5, many of which have emerged following Oracle』s acquisition of Sun/MySQL.
Slide 6: The emergence of these alternatives was triggered, in part, by concern about the future of MySQL. A previous 451 survey,conducted in November 2009, showed that there was real concern about the acquisition, with only 17% of MySQL users believing Oracle should be allowed to acquire MySQL.
Slide 7: The 2009 survey also showed that while 82.1% of respondents were already using MySQL, that figure was expected to drop to 72.3% by 2014. That survey was conducted amid a climate of fear, uncertainty and doubt regarding the future of MySQL, and one of the drivers for our current report was to see if that predicted decline occurred.
Slide 8: To put this in context, we asked the current survey sample (which included 205 database users) about their reaction to the acquisition. While the vast majority of MySQL users reported that they continued to use MySQL where appropriate, 5% indicated that they were more inclined to use MySQL, and 26% said they were less inclined to use MySQL. Not surprisingly the proportion of users less inclined to use MySQL was much higher amongst those abandoning MySQL than those sticking with MySQL.
Slide 9: We also asked respondents to rate Oracle』s ownership of MySQL on a range of very good to very bad. Overall, the balance tipped in favour of a negative perception of Oracle』s track record, while there was naturally a more negative perception of Oracle amongst those abandoning MySQL compared to MySQL mainstays. However, the results showed that the percentage of respondents rating the company』s performance 『very good』 and 『very bad』 was actually quite similar for both abandoners and mainstays. While those abandoning MySQL are more likely to have a negative perception of Oracle, it is not necessarily safe to assume that Oracle』s actions and strategy are the cause of the abandonment. Clearly there are other competitive forces at work.
Slide 10: Not least the emergence of NoSQL, as illustrated in Slide 11, and NewSQL, as illustrated in Slide 12.
Slide 13: Based on some very high profile examples of projects migrating from MySQL to NoSQL, there is a common assumption that NoSQL and NewSQL pose a direct, immediate threat to MySQL. We believe the competitive dynamic is more complex.
Slide 14: While 49% of those survey respondents abandoning MySQL planned on retaining or adopting NoSQL databases, only 12.7% said they had actually deployed NoSQL databases as a *direct replacement* for MySQL.
