Detailed explanation-1: -Modular development is possible in a distributed database, i.e., the system can be expanded by including new computers and connecting them to the distributed system. One server failure will not affect the entire data set.
Detailed explanation-2: -A DBMS is vulnerable to several kinds of failures and each of these failures needs to be managed differently. There are many reasons that can cause database failures such as network failure, system crash, natural disasters, carelessness, sabotage(corrupting the data intentionally), software errors, etc.
Detailed explanation-3: -In a distributed database system, failures can be broadly categorized into soft failures, hard failures and network failures.
