Blackfish™ SQL

Blackfish™ SQL由CodeGear所推出的資料庫引擎，根據官方網頁表示，完全與 SQL 92 標準相容，並且可以在 .Net 或是 Java 平台上執行，而且不管是 .Net 平台或是 Java 平台，資料庫檔案格式完全一致。
雖然說是作為一個 Embedded 資料庫來使用，但他也可以以 Windows 服務形式來執行...以下是官方網頁列出的特色：

  • JDBC for Java
  • JavaBeans data access components for Java
  • XA/JTA Distributed transactions for Java
• Blackfish™ SQL can be run as a Windows Service, as a standalone server or as an inprocess, embedded database
• High performance and scalability for demanding online transaction processing (OLTP) and decision support system (DSS) applications
• For Windows, stored procedures and triggers can be written in any CLR compliant language, including Delphi for .Net
• For Java, stored procedures and triggers can be written in Java
• Zero-administration, single assembly or single-jar deployment
• Database incremental backup and failover

不過目前看來沒有獨立的版本，只包含在 CodeGear RAD Studio 裡面，如果你想單獨購買的話，可能得跟CodeGear聯絡。
