Databases are a means of storing information in a manner that is simple to present to the user and the programs that are known as database applications define the rules for the information that can be contained in the database as well as implementing strong rules for keeping all this information secure in the database. A database application will also be used for making inquiries into a huge dataset such as the patterns in the information that is held within the database. For instance, if your database contains information about cattle, you can make enquiries into the database for the cows that have large horns and those that tend to possess calm, collected characteristics.
A web application on the other hand, is an internet based application that is made up of a frontend and a backend. The frontend is the interface through which the application users interact with the application while the backend contains the application logic and routines that are used in retrieving information, enforcing authentication and so many other functionalities. With a web application, you form an interface through which the user can be able to interact with huge sets of information and this can even be attached to a database.
Databases that work with web applications make references to the information that is relevant to the user much easier and any queries that the user makes through the web application gets to the database from where the necessary information is retrieved. In many cases, modern web applications have an additional server which acts as a database storage and this is where information flows in and out of for the application. A database is expensive to maintain and running the correct queries makes complete sense for the users. With a web application, the interface between the information in the database and a website becomes much simpler.
Web applications present much functionality to the user especially when there is a source of information to base all the moves and decisions that are made by the application. Using information from a database makes the user able to get whatever they had entered into the application previously and they are even free to make their queries more specific in terms of the properties of the information they are looking for. In this manner, handling any information and complex queries on the database is made much simpler by a web application that makes the handling of the data more refined.
In conclusion, databases and web application work very closely with one another and are the reason modern applications are able to interface information to the user much simply. It is a straightforward process of getting the database to work with the web application and any queries that are made through the web application go straight to the database from where the best results are surfaced and presented to the user who then decides on what they are going to do with the information. SQL and other databases are popularly known for their effective in working together with web applications and make the modern internet as effective as it is.
