Interconnection of database servers
This post addresses how to configure and manage connections between different databases, both homogeneous and heterogeneous, to facilitate interoperability across various database systems. Throughout the article, different connection scenarios are explored, starting with configurations between databases of the same type, such as Oracle to Oracle or PostgreSQL to PostgreSQL, and then moving towards heterogeneous connections between different technologies, such as Oracle to MySQL, PostgreSQL to Oracle, and vice versa. It also covers the steps needed to configure links, create users, and modify key configuration files, allowing remote queries.
