Though the Linux operating system is considered as very much advanced and is most frequently updated, still data loss situations do happen in Linux systems resulting in the loss or inaccessibility of important data. In such situations, if you do have another copy of your data, then only you can feel relieved. Among many other techniques to safe guard your data, hard disk mirroring is one such technique, through which you can be able to create an exact copy of your hard disk. ‘Ivconvert’ is an in-built utility in Linux operating system, which is meant to convert the linear logical hard disk volume to an exact or mirror logical volume. However, the point of caution is that if you do not handle the process carefully, it can lead to the failure of your hard disk and data loss thereof. Under such a condition, you need to take the help of any Linux data recovery software to bring back your lost or inaccessible data. A brief about ‘Ivconvert’: ‘Ivconvert’ is...

This is the age of computers and the Internet. Everything can be found online today. People all over the world use words such as ‘hardware’, ‘software’, ‘anti-virus’, and ‘data recovery’. Around five decades ago, nobody knew these words, let alone used them. Prior to the age of computers, physical files were stored. Now, these files are saved on computers on hard disks and other storage instruments. This is a simple way of saving data. However, the computer is a machine. It can fail at any time. During such an eventuality, there is a chance that data will be lost. However, inaccessible data can be salvaged from corrupted or damaged computers. Data recovery is the name given to this process. There are usually three common scenarios where recovery may be required: • System failure: operating system failure, malfunctioning of storage devices, and accidental deletion are some of the major causes of data loss. This usually happens on a com...

Cloud computing is changing the way IT is delivered to businesses and how businesses can now leverage the technologies to be very nimble and agile, yet large. Cloud is a technology that maintains data and applications by making use of the internet and central remote servers. Cloud computing enables users to run their necessary applications without actually installing the software or hardware. The consumers can access their necessary files at any remote computer having internet access. This technology is handy as it facilitates efficient computing by a central storage, memory, process and bandwidth. Cloud computing can be broken down into three components: • “Application” • “Storage” • “Connectivity.” Each segment serves a different purpose and offers different products for businesses and individuals around the world. Cloud computing has two primary deployment models. They are: • Community cloud – In this concept of Cloud, sev...

PHP and MySQL are two components that are almost always present in every web-based program. Data-driven Web applications can use the MySQL which has the main advantages of open source applications. In each database in MySQL there are a few tables. To learn how to access the data contained in the MySQL database, create a database instance with the name “online-store” . Databases can be created using the SQL command “create database online-store” or using PHPMyadmin . Later in the database table named instance make an “employee” table with the columns in it is the “id”, “first-name”, “last-name”, “address” . You can create table “employee” using SQL command as follows: CREATE TABLE IF NOT EXISTS `employee` ( `id` int(11) NOT NULL AUTO_INCREMENT, `first-name` varchar(50) NOT NULL, `last-name` varchar(50) NOT NULL, `address` varchar(200) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHAR...

This is where DS can help create a significant and lasting impact. DS and cybersecurity, two of the most popular career paths, are on a collision course. Very intelligent, seasoned, senior managers do not fully understand the importance, or the complexities, of DS and cybersecurity. “There’s a mad rush in the cyber securit...

Recovering the data from a RAID (Redundant Array of Independent Disks) drive is known as raid data recovery. Raid is the technology that gives you increased storage as it combines many low-cost disks that are not reliable individually to create one unit or an array of interdependent disks which is highly reliable. It is basically a storage technique that lets you divide your data as well as replicate it amongst many disks. When multiple disks are used then it is referred to as a raid array. The basic function of a raid drive or a raid array is to increase the reliability of data and performance. Through RAID Server Recovery, you can not only recover data from a raid server but also from failed hard disks of laptops and desktops, exchange servers and SQL servers. During a raid disk failure raid data recovery is possible but that depends on the disk capacity. The first step during raid recovery is analyzing each and every drive to see if there is any physical damage to them. If there is ...

How to find a data recovery service? I just typed this into the search engine using Google and Wa-la. Data recovery services are in inexhaustible supply. So now the question is, “Which company is right for you?” Are you a business looking for a data recovery system or an individual? A business will probably need a company to do it for them. However an individual may be able to recover their data with a simply software program. You must first try to discover what happened to cause the problem. Some recovery software sites offer a free service of finding the problem of the data loss and providing the information as to whether it can actually be recovered by their software. If the software can recover your data, the recovery software may be downloadable on to your computer. Some problems may be more complicated and may require a recovery technician. Some companies may or may not charge for this service, some companies may offer a free trial. If an individual can not fix the pro...

Data analytics, as a professional skill has come about in so much demand in the last 8-9 years as a result of the capabilities of companies all over the world being able to capture the customers data relating to how to purchase or how the company manages its own financials. Evolution in software development has enabled this capacity. However, there is this constant debate around whether or not the same the software tools used to create the data capturing capabilities can be used for data analytics or do we need more dedicated software tools to achieve the same. One such tool is the SQL based database software, which essentially forms the backend for any operation. It is used to perform queries to get information from data sources. Audit Command Language is another tool, which is dedicated for only data analytics projects. Let us see the major differences between these tools , to settle which approach is better. 1. Easier Interface – The first advantage of ACL over SQL based too...

Data Science and Business Information gathering are sometimes, erroneously, used as interchangeable terms. Both Data Science and Business Information gathering provide a great deal of added capabilities and benefits to your company, even though they are different. A few years ago Business Information, also known as BI, was the king of information used to differentiate your company from your competitors. BI was gathered by sophisticated software that investigated a company’s databases and pulled out relevant information and KPIs that were used to make management and director level decisions. However Big Data came knocking on the door with its myriad of unstructured information coming from everywhere, and BI began to struggle as it needed more structured data to work from. Data analysts that had until more recently were the luxury hiring of larger companies, began to be more sought after. Using appropriate software, they could integrate the mass of Big Data and find not only KPI an ...

Definitions and Overview Business Performance Management (BPM) establishes a framework to improve business performance by measuring key business characteristics which can be used to feedback into the decision process and guide operations in an attempt to improve strategic organisational performance. Other popular terms for this include; Enterprise PM (EPM), Corporate PM (CPM) Enterprise Information Systems (EIS), Decision Support Systems (DSS), Management Information Systems (MIS). BPM: Cycle of setting objectives, monitoring performance and feeding back to new objectives. Business Intelligence (BI) can be defined as the set of tools which allows end-users easy access to relevant information and the facility to analyse this to aid decision making. More widely the ‘intelligence’ is the insight which is derived from this analysis (eg. trends and correlations). BI: Tools to Access & Analyse Data Key Performance Indicators (KPIs) are strategically aligned corporate measures ...

Over recent years, business presentations have changed so dramatically, they are almost unrecognisable from what was done a decade ago. Just as the introduction of PowerPoint/Keynote required business presenters to learn new modality, a similarly different skill-set is required to present effectively now. Then & Now The most important business presentation is the one focused on getting agreement or buy-in from the audience – approval for a purchase or the go-ahead for a project. Previously this presentation was given to people in the room who were hearing the proposal for the first time with a relatively short question and answer session (generally at the end). Now, most of these type of presentations involve both people in the room and others attending remotely, they have seen the proposal well in advance and they expect to be able to ask questions at anytime throughout your presentation. Worse still, some people assessing your proposal might never see your presentation and w...

The central element in the unfolding of Business Intelligence history is predictive analytics and a shift has been underway in employing this technology among all BI Megavendors. Gartner expects that Big Data will drive $34 billion in IT spending worldwide this year. A Boeing jet generates 10 terabytes of information per engine every 30 minutes of flight, according to Stephen Brobst, the CTO of Teradata. Likewise, it is estimated that the number of devices connected to the Internet– currently 9 billion– will reach 50 billion by the end of the decade. These devices will be churning out heaps of data most of which are unstructured (videos, images, audios). Although Predictive analytics falls under Business Intelligence (some disagree), it is different than traditional BI in that BI embodies reports, visualizations, scorecards, dashboards whereas Predictive analytics uses machine learning algorithms to predict the probability of outcomes. Businesses that adopt predictive analyt...
