Databases are collections of information that is organized to allow you to easily manage, maintain and update the store information. The information within a database is organized into rows, columns and tables and is indexed in some form to make it simple for you to locate any piece of information you need. Within a database, the date is updated, expanded, improved and deleted as new information continues to come in. Databases are designed to update themselves by querying the data they are given and running the necessary applications against it.
Most computer databases contain records of some kind within designated files. These records can include sales transactions, inventory and product catalogs or customer profiles. A database manager will provide users of the database the ability to access the information to read or edit it, to create reports and to perform analyses. Some of the more advanced databases offer ACID compliance to ensure that all the data entered is consistent and any transactions made are complete.
It is common to find databases in large systems using a mainframe computer system with maximum availability and security. However, they can also be found in workstations and mid-range systems including IBM’s AS/400 and certain PCs.
The database system has grown exponentially since it was first instituted in the 1960s. The first databases were hierarchical and network databases until the 1980s, when object-oriented databases entered the scene. Today, database configurations include SQL and NoSQL configurations and cloud databases. Databases are usually classified according to how they are used with names such as full text, numeric and bibliographic.
- The relational database was invented by E.F. Codd of IBM in 1970. This tabular database is able to sort and reorganize input to allow the users to access it in a variety of ways. A relational database is designed with a set of data-filled tables that are configured in a set manner. Each table contains at least one data category within a column, while each row contains a certain data instance from the categories defined within the columns.
- A database is distributed when portions of the database are stored in two or more physical locations. Processing of the information within the database is then dispersed or replicated at different points within the network. A distributed database can be either homogenous or heterogeneous. Homogeneous distributed databases all have the same hardware and run the same applications and operating systems. Heterogeneous distributed databases may feature different operating systems and/or applications at each location.
- Cloud databases have been optimized for virtualized environments within either a hybrid, public or private cloud. A cloud database offers unique benefits such as the ability to pay for storage capacity and bandwidth on an as-needed basis. They also have the ability to be 100 percent operational at the “five 9s” level and can be superior in some ways to more traditional database systems.
If you are looking for a database system that will serve your needs, consider using MongoDB. MongoDB is a document-oriented database that has been classified as a NoSQL program. This flexible document data model makes working with any information easy, whether you are building a brand-new app or adding updates to an existing program. MongoDB is an easily-customized program that can migrate date seamlessly between mainframes to public clouds and any other place in between
