Elaborate Medium / Long Term Projects

Elaborate Medium / Long Term Projects

If you need to have a Custom CMS (Back-Office) for professional purposes. you should consider programming a Web Based Application fully tailored for your business workflow needs. This allows your partners/employees to use the application for generating calculations, charts, statistics, spreadsheets, PDF and any kind of work-tool for managing data through a Web User Interface (any browser).

Not all elements are predictable in advance. It is imperative to explore and understand the Users-End needs.

Several tools and methods as well as “common sense”, are required in project management.

Well-defined specifications and well-structured requirements are a useful guideline to initiate elaborate projects.

WEB & CLOUD COMPUTING

Web applications accessible from the internet are often designed to meet specific business needs.

Currently there is strong demand for “mobile computing” (“Cloud Apps”) to access and manage business data on the move, to update website content in real time and everywhere. These applications can be implemented using Open-Source libraries or programming Ad-Hoc features for major corporate routine tasks and activities.

WEB VULNERABILITIES ISSUES

Despite the popularity of “Cloud-Computing”, today the safety of these interactive applications cannot be guaranteed. Issues of Confidentiality, Integrity and Availability of online data must be considered in advance, despite the applicable “best practices”.

Any application exposed to the global network is full of vulnerabilities. Preliminary analysis of the operational context is essential for those companies dealing with sensitive information.

RESTful WEB SERVICES

Representational State Transfer (RESTful) is an abstraction of the architecture of the World Wide Web; more precisely, REST is an architectural style consisting of a coordinated set of architectural constraints applied to components, connectors, and data elements, within a distributed hypermedia system.

RESTful ignores the details of component implementation and protocol syntax in order to focus on the roles of components, the constraints upon their interaction with other components, and their interpretation of significant data elements.

A REST API consists of an assembly of interlinked resources. This set of resources is known as the REST API’s resource model.

REST and HTTP are Not the Same

A REST API consists of an assembly of interlinked resources. This set of resources is known as the REST API’s resource model.

Hypertext (or hypermedia) means the simultaneous presentation of information and controls such that the information becomes the affordance through which the user (or automaton) obtains choices and selects actions.

Hypertext does not need to be HTML (or XML or JSON) on a browser. Machines can follow links when they understand the data format and relationship types.

The resources are acted upon by using a set of simple, well-defined operations. Also, the resources have to be decoupled from their representation so that clients can access the content in various formats, such as HTML, XML, plain text, PDF, JPEG, JSON, and others.

The clients and servers exchange representations of resources by using a standardized interface and protocol. Typically HTTP is the most used protocol, but REST does not mandate it.

Metadata about the resource is made available and used to control caching, detect transmission errors, negotiate the appropriate representation format, and perform authentication or access control.

Most importantly, every interaction with the server must be stateless.

All these principles help RESTful applications to be simple, lightweight, and fast.

Methodologies & Work Planning

For specifically tailored solution web-based systems, well-defined specifications and well-structured requirements are necessary for the achievement of complex projects.

For long-term Software Development, known methodologies to plan and structure IT projects may be used. These methods are called “Agile software development” which promotes adaptive planning, evolutionary development, early delivery, continuous improvement, and encourages rapid and flexible response to change.

Nevertheless, these methods require a “cross-functional team“: a group of people with different functional expertise working toward a common goal.

One among other is called Scrum. a framework for effective team collaboration on complex software projects. Common sense and field experience are also required in project management. In addition to technical implementation and needs assessment.
