ZARA is a Spanish clothing and accessories retailer based in Arteixo, Galicia. Founded in 24 May ,1975 by Amancio Ortega and Rosalía Mera, the brand is renowned for it’s ability to deliver new clothes to stores quickly and in small batches. Zara needs just two weeks to develop a new product and get it to stores, compared to the six-month industry average, and launches around 10,000 new designs each year. Zara was described by Louis Vuitton Fashion Director Daniel Piette as “possibly the most innovative and devastating retailer in the world. The company produces about 450 million items a year for its 1,770 stores in 86 countries.
The Zara has made of use of Information Systems (IS) and to advance in many areas. This has resulted in huge success for the company. This included application of Business intelligence (BI) involves technologies, practices for collection, integration and applications to analyze and present business information. The main aim of business intelligence is to promote better business decision making.
BI describes a group of information on concepts and methods to better decision making in business. This is achieved by employing a fact based support systems. The intelligence systems are data-driven and sometimes used in executive information systems. Predictive views on business operations can be provided by use of BI systems. predictive views on business operations can be provided by use of BI systems since historical and current data has been gathered into a data bank performance management benchmarking is done whereby information on other companies in the same industry is gathered.… Read the rest
Proprietary software can be defined as closed software that is distributed under a license agreement that limits any modifications to the software. Its just opposite to the concept of Open source software. Open source software can be defined as software that is distributed freely under a license agreement with no limitations on changes made to the source code.
Many proprietary corporations make software freely available to users. For example, Adobe provides users with the Adobe Acrobat Reader. The Adobe Acrobat Reader is an application that users to view documents that have been saved in the portable document format (PDF). The PDF format is developed by Adobe and has become a standard in saving files as electronic documents. ‘Standardization’ and ‘compatibility’ are the two main drivers for the success of proprietary software. Any user that opens a PDF formatted document with Adobe Acrobat Reader is confident that the document will be accessible and readable. The standardization of the PDF format for document files is what made almost every document processing application incorporate it into their processes. In turn, that made the PDF format compatible within document processing software. However, software corporations that incorporate a process to save files as PDF formatted documents must pay Adobe a licensing fee in order to have access the code that will convert files into PDF in conformity with the Adobe Acrobat Reader application. The Adobe Acrobat Reader creates user dependency. Users that create documents desire software that understands the PDF format and the software vendor must pay Adobe for licensing, in order to meet the requirements of its users.… Read the rest
Networking is very important in the world of computer. Networking is the activity of connecting the computers to each other to make-up the computer network. In other word is the purpose of sharing data through linking of two or more computing devices together. Networks are built with a mix of computer hardware and computer software. A computer network is a collection of computers and devices connected together via communications devices and transmission media.
There are few factors that affect the performance of computer networks. Those factors will reduce the quality of service of the network. The major factors are Latency, Packet loss, Retransmission, Throughput and Queuing delay.
Latency is the kinds of delays typically incurred in processing of network data. A low latency network connection is one that generally experiences small delay times, while a high latency connection generally suffers from long delays.
Although the peak bandwidth of a network connection is fixed according to the technology used, but the actual bandwidth which is obtained change over time and is affected by high latencies. Excessive latency creates bottlenecks that prevent data from filling the network pipe, thus decreasing effective bandwidth. The result of latency on network bandwidth can be temporary which may lasts for a few seconds or constantly depends on the source of the delays.
To measure the Network Latency tools like ping tests and trace-route are used. The measuring is done by determining the time it takes a given network packet to travel from source to destination and back, and this the so-called round-trip time.… Read the rest
