数据来源: DB-Engines 发布的 4 月份最新的数据库排名。MySQL 上升迅速，目前已经超过微软的 SQL Server 排在第二位。
统计排名的主要依据：
- Number of mentions of the system on websites, measured as number of results in search engines queries. At the moment, we use Google and Bing for this measurement. In order to count only relevant results, we are searching for “<system name> database”, e.g. “Oracle database”.
- General interest in the system. For this measurement, we use the frequency of searches in Google Trends.
- Frequency of technical discussions about the system. We use the number of related questions and the number of interested users on the well-known IT-related Q&A site Stack Overflow.
- Number of job offers, in which the system is mentioned. We use the number of offers on the leading job search engine Indeed.
- Number of profiles in professional networks, in which the system is mentioned. We use the internationally most popular professional network LinkedIn.
