In this article, we will learn how to create a RAID 5 Array configuration using the ‘mdadm’ utility.The ‘mdadm’ is a utility which is used to create and manage storage arrays on Linux with RAID capability where the administrators are having great flexibility in managing the individual storages devices and creating the logical storage with a high performance and redundancy.RAID 5 Array is a type where we implement by striping the data across the total available devices. Every component of the each stripe is calculated by parity block. If any device fails the parity block, it will use the remaining ... Read More

In this article, we will learn how to create a RAID 0 Array configuration using the ‘mdadm’ utility.The ‘mdadm’ is a utility which is used to create and manage storage arrays on Linux with RAID capability where the administrators are having a great flexibility in managing the individual storage devices and creating the logical storage with a high performance and redundancy.RAID 0 array will work by dividing the data into small chunks and strips that data across the available storage disks, which means that each and every storage disk will contain a portion of data and when retrieving the data ...

There are two ways of organizing data in a DBMS − one is row-oriented database and another is column-oriented database. The basic difference between the two is that a row-oriented database stores the data tables by rows, whereas a column-oriented database stores the data tables by columns. Read this article to learn more about row-oriented database and column-oriented database and how they are different from each other. What is Row-Oriented Database? A Roworiented database is a traditional database like Oracle, MySQL, etc. It stores data tables by rows and the common method of storing a table is to serialize each ... Read More

A “cloud” in the technological sense, can be defined as a huge online place for storing and accessing data and program files in the internet, instead of your computer hardware- like local disk. When we talk about storing and accessing data, our first concern is how secure is our data, how much can we rely on the cloud environment. Cloud environment is as safe as data stored in an individual data server.Cloud is the latest trend in technology and most of us store all data in cloud housed in Dropbox, Google Drive. Generally, people assume that all the data stores ... Read More

Computer programming entirely revolves around data. It is data over which all the business logic gets implemented and it’s the flow of data which comprises the functionality of an application or project. Hence, it becomes critical to organize and store the data for its optimized use and perform effective programming with good data model. From the surface, both data type and data structure appear to be the same thing, as both deal with the nature and organizing of data, but there is a big difference between the two. One describes the type and nature of data, while the other represents ... Read More
