Service Oriented Architecture Analysis

As a modular, self-describing type of software service, Web services are self-contained applications that can be:

Legacy system is the general designation of all the system Loblaw used before adopting SAP. Each Legacy system has its own database so that different departments in Loblaw are using different Legacy system to upload and maintain the data they are using. One of the most commonly used Legacy is CICS, which allows employees to upload and maintain transaction and payment document at Loblaw. Whereas, SAP is an enterprise resource planning software that integrates a company’s core business function in a seamless and efficient manner. It also links function through a central database in order to

The second challenge involves properly synchronizing information between the SaaS application and legacy systems. Legacy systems are most likely to be the system of record for critical corporate information about customers, products, orders, and more! SaaS solutions need to synchronize information with the particular legacy subsystem so the company has a single accurate real-time view of business activities through their data. Furthermore, when dealing with differing data formats and workflows between SaaS/legacy systems it is challenging and must be done securely and reliably.

Managing this new model is a challenge for IT leaders. The drastic differences between the old systems and the new processes mean that there

Sotera has attempted to evolve with emerging development technologies in times past, however, majority of the specialized service offerings that we provide have become progressively focused toward the intelligence market and or Cyber and Data Solutions and not so much strictly software development efforts anymore. Notwithstanding the aforementioned, the traditional waterfall methodology and some elements of agile are utilized in support of client requirements; typically specific to what he client desires. On the occasions where we are requested to propose the best solution to client requirements, we often propose a modified agile methodology which blends traditional elements of software implementation methodology with agile. Sotera proposes the use of a general Enterprise Application Implementation Methodology (EAIM) for each development project that we pursue. Within our proposal our focus is detailing our EAIM, which most closely resembles the Waterfall Methodology.

The new leadership of Tony’s Chips has decided to move the website to an internally hosted site instead of its current external site. The newer internal website should be redesigned in order to allow customers to buy products online. The development of the System Development Life Cycle (SDLC) created a much easier way to develop systems. This process will be used for Tony’s Chip’s new independent company. Each step in this process is clearly defined through each individual phase. The SDLC consists of five different phases that will be utilized in this project. The five phases are systems planning, systems analysis, systems design, systems implantation, and systems support and security. The sequential steps are often called “a waterfall” because each phase should be completed before moving on to the next. Once a phase is completed, there is no returning to it.

The creation of new system is the next activity. The activity is comprised of incorporating the features, needs and requirements desired by the customers and the business. Under this activity, the implementation team undertakes the migrations for existing components from the old system into the new system (Wang, Chialinlin, Jiang & Klein, 2007). Under the components migration, all the

Service-oriented architecture is best utilized in a distributed heterogeneous environment where business activities happen between loosely connected services. Thus, ensuring that the framework in this type of structure is secure can be quite challenging. Likewise, the success of SOA is decided by the totality to which design principles are helpful to service development. Design principles are the essence of service-orientation, and they provide the guidelines for the development of service logic that is interoperable and acute. Hence, design principles are the formation of loose coupling, reusability, statelessness, discoverability, abstraction, composition, and the inclusion of a service contract. Administering traditional information
