Database replication is a mechanism which allows distributed databases stay in synchronized and consistent state. In heterogeneous case there is a set of databases with different platforms, what additionally complicates this process. High demand for this technique causes that replication issue is developed very fast nowadays. Database replication mechanism consists in intercepting data modifications and propagating them to other databases where they are executed again. This process is very complex and there are many variants and types of replication. In this paper are discussed database replication classification (synchronous, asynchronous, multiple master, master slave), kinds of replication conflicts with resolving strategies, data modification capturing and publication-subscription model. There is introduced an example for realization of replication in heterogeneous environment. Also are discussed aspects of independence database assess mechanism from specific platform, what can be used in implementation of heterogeneous database replication.
