Different Types Of Distributed Databases And How To Choose One

Many companies are making the move from traditional central databases to a distributed database. There are a number of different kinds with cloud-based databases being the most popular. One of the biggest advantages distributed has over central is the ability for each branch of a business to continue to operate even when the network is down. In spite of continually evolving technology, a big concern associated with the distributed databases is that of keeping data secure. Each distributed model has its own features and security basics that are used to protect valuable data.

Duplicated Database

Duplicated refers to the entirety of the data that is stored in each individual database. The data in each computer is up-to-date to the degree that recent updates are made so that the main database or master computer does not have to be accessed for any of the information needed to function on a daily basis. This type of database is best for companies that don’t require a lot of scalability.

Partitioned Database

The database is divided into sections, or partitions, to accommodate each department or facility with the data it needs to perform tasks. For example, the local branch of a business might not need the data used internationally, but only that which pertains to their state or specific location. A partitioned database can also be used when there are different teams and/or facilities that have specific responsibilities not shared by the others.

Partitioned and Index Database

This type of distributed database is partitioned and also keeps an index of the data stored in databases at other locations or branches. Updates are made to the index regularly, usually overnight.

Keeping the Database Secure

As new technology changes the way the database is used or updated, security issues must be addressed. It is possible to have a database that is in one of the distributed models and keep data secure when a few important steps are taken. These include:

• Providing every user with a password that allows them the level of use that they require to do their job.

• Using additional software as a security backup to authenticate the user and the type of data they access.

• Encrypting data to secure it when it crosses the network between the database and the location of the users.

If the right steps are taken, the distributed database can provide a number of solutions for businesses with multiple branches. Depending on your business model, a partitioned database allows you to place data into user-specific categories for added security.

The distributed model has become increasingly popular for a number of reasons. Most importantly, a distributed database takes the worry out of storing and retrieving data that exists when a central database is used. A primary example of large companies that have made the switch to this database and the trust that organizations place in them is that of Google. If Google can rely on the distributed model for organizing search data, it is obviously a reliable resource that will work for other businesses, both large and small.
