An Overview of Storage and Database Systems
With so much data being generated with each passing day, there are several factors to consider when deciding where to store that information and how to access it. New trends continue to emerge, as basic principles still stand. The challenge is to embrace both to come to the right solution.
Data Storage Trends
The Hybrid Cloud
This model allows a company to keep data where it is best suited for consumption by various parties. Tightly controlled data and applications can be kept on a private cloud where they are available to a select group of individuals, while other data and apps can be housed on public clouds. Public clouds are effective for enterprise-wide accessibility in support of varied workgroups with different needs for similar applications.
Virtual networks and storage controllers are becoming increasingly more common. Virtual components that are well-integrated with their physical counterparts will facilitate better archiving, backup and recovery administration. By allowing information to be controlled virtually, it becomes easier to migrate and cluster data in ways that enable optimal accessibility and usage.
OpenStack is an open source cloud computing platform that enables the creation of all types of private and public clouds. OpenStack is the product of a global development community, originally formed by Rackspace Hosting and NASA to create feature-rich technology that would support the deployment of large, scalable clouds for business and research applications.
Companies are using data to make more decisions than ever before. They are running analytics to evaluate processes, look for patterns, and pinpoint outliers. Making the right data available to the right people at the right time, however, requires some study.
Types of Databases
Databases can be defined in terms of the number of users, where the data is located, and the purpose and format of the data being collected and stored. These include:
- Single User, Desktop, Multi- User, Workgroup and Enterprise
- Centralize, Distributed, Operational and Transactional
- Unstructured, Semi-Structured, Formatted and XML (Extensible Markup Language)
Database Management Systems
Once the necessary functionality is established, there needs to be a database management system (DBMS) to support the way that data is accessed and used. Essential features of a DBMS include:
- Data Security Information security is a major issue facing businesses of all sizes. Controls must be put in place in order restrict access internally as well protect data from external breaches.
- Data Integrity At the most basic level, data integrity ensures that there are no duplicate records and that only one user can make changes to a record at one time.
- Interactive Query This is the feature that makes analytics work by allowing users to pull the types of data they need from the overall database.
- Data Entry and Updates Authorized users are allowed to enter and edit data based on transaction and file types. The DBMS can be programmed with controls that provide a real-time log of users in the system, which is useful in the case of an audit.
This brief overview is just the beginning of the ever-growing and always-challenging world of data management. There is no shortage of opportunity – or information – available to you in this field.Sources: http://searchstorage.techtarget.com/NetAppSponsoredNews/Top-10-Storage-Trends-for-2014 http://www.tomsitpro.com/articles/enterprise-storage-solutions,1-1826.html http://www.openstack.org/ http://www.slideshare.net/jothamgadot/9780538469685-ppt-ch01 http://www.pcmag.com/encyclopedia/term/40952/dbms
