What Are Some Disadvantages of Databases?

Databases tend to be expensive and require continued upkeep which is costly, they can be extremely complex and confusing for users who do not understand the system, and if users do not know how to protect their information properly, databases can be used to access classified information and are prone to viruses or spam. With any database, users must know how to navigate through the information and sensitive information must be secured so that the wrong people cannot access it.

A database is simply an organized collection of large amounts of data on a computer. Databases are used in a wide range of applications, and they can be public or private, on the internet or within a single company's server. Setting up a database for a company can be costly, and most companies need to hire an information technology director to maintain all databases and make sure that everyone can get their information. Databases can be very easy to operate, but some are very complex and require users to know the system very well before accessing data.

Databases also present a security risk. Companies or individuals may have sensitive or classified information on a database. Those companies or individuals need to know how to secure their information, otherwise the data could be accessed by an unwanted party which poses potential danger to the person or company.
