Introduction

When someone wants to design the interior of a home they will naturally have to consider what software to use. Most will use database systems in some way or another. The latest ones are very different from those that have come before them.

A real-time database is one that uses real-time processing software in order to deal with workloads which are in a constant state of change. This is in contrast to older systems where data remains consistent and unchanged over time.

The stock market is a perfect example of how this is utilised by businesses. It is a system where the data is in a rapid state of flux. Databases for stock markets are required to keep track of the current value, even as it is increasing and decreasing in real-time.

This type of database has a wide range of possible applications. Several sectors benefit from using them. This includes banks, accounting firms, medical facilities and law departments. They can also be used for process control, analysis of scientific data and as a multi-media tool.

Issues

There are some flaws to these systems. For instance, if two transactions of the database need to access a part of it at the same time then this can create an overload issue. A good example of this is if two people were to apply for a position. If they both entered their submission at the exact same time then only one of their registrations would be recognised by the database.

In order to prevent this problem, real-time systems sometimes use scheduling algorithms that can prioritise multiple submissions, ensuring that none of them fail. Deadlines also form an important part of the way that they process information. These are scheduled through timestamps. If a data transaction does not complete by the deadline then the system deals with it in a more sophisticated fashion than older databases.

Other Applications

Online gambling sites often use this type of system, as it allows them to deal with multiple matches or races at the same time that the results are being announced. Sites such as Unibet give gamblers access to a huge number of results which inform them of whether or not they have won. These databases can be utilised to set up many different bets all simultaneously.

Another useful application is traffic information. If someone is driving then they can access programmes that let them know of any incidents or jams on the road that they are travelling on. This allows them to divert their course if necessary. These programmes rely on real-time databases to process traffic activity info at the same time that it occurs.

They also are better suited to the emerging types of modern technology. This includes smart devices, such as mobile phones. A user will be able to access a colossal amount of digital programmes on these. If the information being processed can adapt to change and relay these changes in real-time then this will help to speed up the devices response.

The Future

It seems likely that the database systems of the future will be based around real-time processing. It allows changes to be made in a much more consistent manner than older types. Furthermore, they will be able to process faster, appealing to multiple business institutions.

This method also improves access to the data. When changes occur the user will be able to see this in as fast a time as possible. Furthermore, indexing is refined so that users can have a better visualisation of information. All these factors point to real-time databases being used increasingly in the years to come.
