Solutions>Software & Database Development


Our software team is commited to designing, building, and deploying industrial strength systems. Our clients have little room for “down time” and that is exactly the environment where we excel.

Software development has continuously changed and its flavors are numerous. Therefore, our consultant training program is very important to help keep pace with the changing environment.  

Our services include the full range of software services: 

  • Database design: using SQL 2000, MS access, Oracle 8i, 9i, Linux MySQL
  • Stored Procedure to obtain faster response times
  • Writing Programs using: C, Visual C+, Visual C#, Visual Studio.Net, J2EE, WebSphere 

Experienced consultants are aware that each software development undertaking is unique and that specifications usually evolve. With solid underlying architectures, these changes in direction need not derail system development efforts. Modular components permit a flexibility that can accommodate the natural evolution across lines of business and platform.

In the case of new development, all of our system designs are walked through by a central design committee and then presented to the end client for review.

Because most of our clients have their own Information Systems departments, we are aware that a technology transfer of information is essential to the ongoing internal support of applications.
 

ASTORNET QUALITY

Astornet is presently managing its projects using CMMI maturity level 5 with an official appraisal to be performed within few months.

What it means for you (our client):
      > Better control of products and processes
      > Lower effort and schedule overruns (91% projects completed
         on schedule as opposed to an industry average of 50%)
      > Better risk management for your projects
      > Significantly reduced costs (cost savings up to 40%)
      > Higher customer satisfaction.

 

Our software engineering process

A project is assumed to be managed in iterations, where each iteration covers everything from requirements engineering to system level (and acceptance testing). The advantage is that it is possible to evaluate progress in earlier iterations to plan later iterations.

For example, given that a 80% of the use cases (describing a scenario where the system is used) should be covered during one iteration and only 30% were actually covered, it may be desirable to decrease the scope of the system or terminate the project. Adding new resources can be a viable solution, but this does not necessarily improve the situation.

                        

The emphasis in early phases moves from requirements engineering, to design and implementation in the intermediate phases and ends with an emphasis on system level and acceptance testing in the last phases.

Each iteration can be viewed as follows:

There are three overall activities:

  •  planning
  • software quality assurance
  • configuration management

These three activities are used to control the project in various ways.

Further, the actual production of software can be viewed as 6 phases:

  • requirements engineering
  • design
  • implementation
  • low-level testing
  • integration testing
  • system-level testing

As depicted, different kinds of knowledge is desirable in the different phases, e.g. domain knowledge is necessary during requirements engineering and system-level testing and architecture knowledge is valuable during design and integration testing.
 

Modeling with respect to software engineering

One way of viewing software engineering is as a process of modelling. That is, we model reality to understand it (to elicit requirements), which we usually model as a software architecture.

This software architecture is then translated into a model (an application or program) that can be executed on an execution environment (e.g. an operating system or a language environment).
