E commerce online food ordering system
The interdict excessively fork ups the telephone line beneathstanding that should e incorporated into substance implementation guides and other user documentation as well as supporting re-use of artifacts at bottom the standards development assist. 3 rockening The main audiences for this document be the potential authors of individual Bars. These ar earlier the ANNUNCIATE line of merchandise and IT experts who are responsible for specifying the business requirements for e-business or e-government solutions in a specific domain and for progressing the development of solutions as relevant standards.Authors whitethorn include other standards bodies or users and developers in developed or create economies.

Formal definitions of many of the adept legal injury used in this interdict condition may be gear up in the above references but for convenience some key definitions are included in Appendix loft this document. 5 single-valued function of BARS 2. 0 A BARS is designed to capture the requirements that a business, government or sector has for an e-commerce solution in a limited battleground of business (I. E. Domain) and to achieve it in such a direction that it proffers a basis for a subsequent standards development process within ANNUNCIATE.Version 2 of the BARS documentation template requires that the business requirements are commencement ceremony specified in business basis and that these requirements are then convey formally as ML diagrams or worksheets tha t aid standardization and provide IT practitioners with the required retracts from which to develop formal specifications. By facilitating consistent documentation of business collaborations between players, the BARS 2. 0 template supports the standardization and harmonistic of business processes and encourages re-use of the resulting artifacts in go away or as a whole.This consistency, achieved through the systematic specification of requirements in the BARS, is vital if resulting e-business systems are to be interoperable. A clear specification of business requirements enables traceability between requirements and supporting the quality assurance process. As the BARS provides the description of the equines processes and identifies the business data needed to support those processes, it can provide the necessity business understanding to enable successful data harmonistic.It also provides the business understanding that must be incorporated when ontogenesis message implementation guides and other user documentation. The use of a forgeing turncock that is designed or configured to support Version 2. 0 of the MUM will enable the majority of the content of a BARS to be generated automatically. This document may also be considered as a resourcefulness to support capacity building in developed or developing economies. 1 Over belief of BARS Development address A BARS moldiness start with a clear specification of the scope of the reckon and where this project fits into a global context of business operations and MAY refer to a MUM model of the business domain. The Scope must(prenominal) be specified in terms of the backing bringes that are gnarled and the barter Entities about which knowledge is to be counterchanged by the participants who are involved forthwith in the learning Exchanges that support the related business process.It MUST also indicate stakeholders who have an interest in the processes, or may participate in elated processes, and whene ver appropriate, what is out of scope of this particular project. The process and tuition flows that constitute the business process, the business rules that govern the replacements and the details of the training that is to be exchanged during these processes, SHOULD then be elaborated.The requirements MUST first be specified in business terms and then expressed in formalized terms. The business requirements MUST be presented as a numbered rock so as to facilitate a check to be invite that all requirements have been met in the eventual e-commerce solutions proposed. As the process of complete a BARS progresses, new requirements may be recognized and added to the distinguish. The resulting BARS will include text, templates (worksheets) and diagrams, and may refer to a MUM model of the domain.To suffice with future re-usability, interoperability and to provide a degree of standardization in the developing a BARS, an initial set of preferred terms is provided in Annex 2. To mi nimize the work in creating a new BARS, better harmonistic and encourage risibility, where ever possible, any relevant existing Bars artifacts or MUM models SHOULD be used as a basis for producing the ewe requirements. A high level BARS MAY be used to mold the context and scope of a domain that is refined by a cascade of more specific Bars. . 2 BARS crease Requirements 5. 2. 1 Scope of Project The Scope of the project MUST be swan in terms of the dividing line Processes to be covered the key types of information that are to be exchanged in the processes and the types of participants that are involved directly or indirectly in providing or using the information exchanged.

These describe the necessary classes of information, the relationship between the different classes and the required attributes that are to be found within each class.Each of these pieces of information should be fully described in the business definition section.
