Asynchronous Database Access Library with Silent Automatic Reconnections

Abstract

Nowadays in production applications is used synchronous access to the database. In synchronous access is main thread blocked until SQL statement is not executed which in case of long-running SQL query or network problem causes application jamming. The diploma thesis deals with possibilities and the principles of data exchange between the Firebird database and applications developed in Delphi programming language to find a solution for this problem. The aim of this thesis is a library for asynchronous database access, where to perform multiple requests in parallel form is possible. The database library also contains functions for automatic silent reconnections, automatic testing and others to make it as comfortable as possible for programmers who will use it.
