There are many advantages to using a database, like a reduction of useless data, increasing consistency and improving data integrity while there are also disadvantages, like requiring lots of time for development and maintenance, substantial startup costs and application programs becoming reliant on the database. Databases can be extremely important tools for managing large amounts of data but they also have their own downsides.
Data is frequently redundant. There are numerous instances when data quickly becomes superfluous and reaches such massive proportions that it makes the collection almost impossible to use for practical purposes. This is why databases can be so important. They can be programmed to help organize the data, maintain it and even allow users to find exactly what they need without the hassle of having to sift through heaps of information they don't care about. Databases can also provide important security. They keep all of the information in one place. This doesn't just improve the expedience and functionality of various applications, it also protects those applications from being compromised. Databases, once made, also help to save various costs.
The problem with databases, though, is that creating them can be a long, costly venture. Once they are made, they can save money, but databases that are made from scratch can require huge amounts of money. Furthermore, databases oftentimes require hardware and software for their startup, and these things can also rack up big costs. What's also highly disadvantageous is that databases will be hooked up to various application programs. So, if the database is compromised, all of those applications will subsequently suffer.
