Service Oriented Architecture (SOA) : Detail Article

Service Oriented Architecture or SOA is an architectural pattern of information technology in the field of distributed systems for the services to structure of IT systems. A special role is played by the focus on business processes, their levels of abstraction are the basis for concrete service implementations : Forgive the loan for example, is located at a high level; behind it hides a banking enterprise, a business process with some of the people are involved and the information systems (Open the business relationship, Create one or more accounts, credit agreement and so on) are carrying the customer in to a service at a lower level. By assembling (or orchestration) of the services of lower levels of lower abstraction level, the whole system can be made quite flexible which allow maximum re-usability of higher abstraction levels. Previously we published an article on How Service Oriented Architecture Ties Cloud Computing, that is basically an example of  implementation of the Service …

Data Portability in the Cloud : Customer Loyalty vs. Trust

Data Portability in the Cloud applies to who move their data or even want to get back. Vendor lock-harm data portability and adoption of cloud services. Numerous articles has been published by us on the point Vendor Lock-in. First, we wrote about the Points to Check for Cloud Computing and Vendor Lock-in, secondly the article on practical Lock in Effect in Todays Technology and Gadgets, specially about Lock-In in Cloud Computing Services. Data Portability in the Cloud is often neglected. This firstly includes the relocation of existing data to a cloud provider, in particular the access to their data when they are once the cloud provider. With the use of cloud services especially the issue of data storage, data portability in the Cloud is hotly debated.…

Four Thirds Standard in DSLR

Four Thirds Standard in DSLR is a matched standard for lens mounts. It was present from the beginning regardless of lenses, cameras or sensor sizes. This allowed to solve compatibility issues with legacy components and the compromises in the design of new components. The first such camera with Four Thirds Standard, was the Olympus E-1, which was introduced in 2003. The standard of
Four Thirds Standard defines, among other things; the sensor dimension, the lens mount including the protocol, the imaging circle, the flange focal length (38.85 mm), optical requirements such as the maximum angle between incident rays on the sensor.…

Perl Programming Language

Perl Programming Language is a free, platform-independent and interpreted programming language or scripting language.It supports multiple programming paradigms. Linguist Larry Wall designed Perl in 1987. Originally Perl was intended as a tool for the processing and manipulation of text files especially for system and network administration, Perl now has also integrated in the development of web applications and in the bioinformatics. Perl is traditionally represented in the financial world, especially in the processing of data streams of various news sources. The main objectives are rapid problem resolution and maximum freedom for programmers. The processing of text using regular expressions as well as many freely available modules, which is the central strength of Perl programming language. Perl is high-level, general-purpose, dynamic programming language. The full form of PERL is Practical Extraction and Report Language, some considers as acronym of Pathologically Eclectic Rubbish Lister. Pearl was the intended name but it had to be changed because there was already …

Optical Networks and Low Latency for Data Centers

Optical Networks and Low Latency for Data Centers are requirements for new applications and wider variety of services, including those for cloud computing. Cloud computing is becoming to a segment the mainstream and it is considered by many to be the next big change that will involve in telecommunications networks. This service requires operators that connect data centers together, paying attention to the latency of the path and the system used and if necessary, applying corrective action to the network.…

Startup and Cloud Computing : The Importance

Startup and Cloud Computing can have good relationship, but still we do not talk that much about Cloud Computing and startups or entrepreneurship. Unknowingly we use cloud computing – Skype, Dropbox and our internal management of cloud servers. Then we have the email and GitHub for development, we commit a change after testing on cloud based platform. Simple, is not it? We would love to make the bill for an young startup lesser.…

Telepathy : Basics and Difference with Cognitive Science

Telepathy is more towards paranormal phenomena such as precognition whereas Cognitive Science is the scientific study of various process of Mind. Previously we wrote about Cognitive Science in brief. We actually do not want to go in to kind of paranormal phenomenon rather we want to stick within the boundary of Computing and Neuroscience. This is to some extent, on request article on Telepathy from a neutral view. The basic motto of this article on Telepathy is to demote impractical claim of ‘future products’ or kind of commercialization in some way or the other.…

Medium Format DSLR Details

Medium Format DSLR are high end professional DSLRs with sensor size up to 36 mmx48 mm, very high pixel density like 40 million pixels as opposed to full-frame DSLR. We ‘normally’ use full-frame DSLRs as professional and high end DSLRs which has the sensor size equivalent to 35 mm film SLR camera. During the last phase of film cameras, 35 mm became the mainstream, while Medium Format SLR and other kind of cameras had bigger film size. It must be noticed that, most consumer grade DSLRs are equipped with APS-C sized sensor – not a Full-Frame sized Sensor.…

Symmetric Multiprocessing System

Symmetric Multiprocessing System is a multi-processor based Architecture where there are two or more identical processors with a shared address space. This means that each processor in Symmetric Multiprocessing System has the same (physical) address and the same alloted memory or the same peripheral registers. Most multiprocessor systems today are of Symmetric Multiprocessing architectures.…

APS-C Format Sensor

APS-C Format Sensor is the acronym of Advanced Photo System type-C. The size of APS-C Format Sensor is approximately equal to the film APS size negative. The original negative of APS measures 25.1 × 16.7 mm with an aspect ratio of 3:2. Sensors with approximately of this APS dimensions are used on many consumer grade digital SLRs and on advanced Point and Shoot Camera, DSLM cameras etc. APS-C Format Sensor is considered inferior than standard 35 mm or Full-Frame Sensor but the cost is significantly less than that of Full-frame.…

Relational Model : Outline

Relational Model is a data model based on predicate logic and the theory of sets. Relational Model is most commonly used today to manage data dynamically. Edgar Frank Codd discovered it and IBM laboratory in San Jose, California; quickly established it as a new paradigm in the database models. The basic idea is the use of “relationships”. These relationships may be logically considered as sets of data called “tuples”. Although this is the theory of relational databases was created by Edgar Frank Codd , most of the time it is conceptualized in a more easy to imagine, that is, thinking in every relationship as if they were a table which consists of records and columns (also called fields).…
