firebird2.5-classic 2.5.6.27020.ds4-1ubuntu1 (arm64 binary) in ubuntu yakkety

 Firebird is a relational database offering many ANSI SQL-99 features that
 runs on Linux, Windows, and a variety of Unix platforms. Firebird offers
 excellent concurrency, high performance, and powerful language support
 for stored procedures and triggers. It has been used on production systems
 under a variety of names since 1981.
 .
 The "classic" architecture uses a new process to handle each connection
 which results in somewhat slower operation (but is said to be faster
 than "super" on local connections) yet can take advantage of multiple
 CPUs on SMP machines. This is the "traditional" architecture.
 .
 This package contains the 2.5 branch of Firebird.
 .
 Firebird is a commercially independent project of C and C++ programmers,
 technical advisors and supporters developing and enhancing a multi-platform
 relational database management system based on the source code released by
 Inprise Corp (now known as Borland Software Corp) under the InterBase Public
 License v.1.0 on 25 July, 2000.
