We discuss the evolution of Praxis, a model-driven process framework, building on feedback from educational and professional applications, along the past fifteen years. We follow the evolution from Praxis first version to the current one, discussing what was introduced in each. For past and current versions, we classify model improvements, discussing their nature and rationale, derived from rec...

Programming Language is a certain code that designed to create an application program design. The number of programming languages currently circulating, it necessary test the level reliability language. purpose this research compare language PHP and Codeigniter Framework, both these are back end so they have close specifications in processing data from database. Implementation developed with CR...

Abstract In Information Systems (IS), the search for a good design is still relevant issue. IS, two sub-systems coexist, applications and data. To articulate these sub-systems, some authors opt CRUD matrix. Similarly, Axiomatic Design (AD) theory studies how functional requirements are related to parameters using this paper, application sub-system corresponds requirements, data parameters, matr...

Programmers of relational database applications use software solutions (Hibernate, JDBC, LINQ, ADO.NET) to ease the development process of business tiers. These software solutions were not devised to address access control policies, much less for evolving access control policies, in spite of their unavoidable relevance. Currently, access control policies, whenever implemented, are enforced by i...

Reliance on multiphase fluid-dynamics models, which are developed with relatively limited experimental data, requires a quantitative assessment of the solution variability due to the approximations. In this paper, uncertainty in the Eulerian multiphase boiling model in the Nphase-CMFD code is assessed in the context of the DEBORA test case and the CRUD problem. The models under consideration ar...

in order to study the effects of sowing date and plant density on forage yield and some morphological characteristics of corn, an experiment was conducted in gorgon research station in 2008. in this experiment two sowing date (18 april and 21 june) and six plant densities (25000, 45000, 65000, 85000, 105000, and 125000 plant per hectare) were evaluated in form of factorial experiment (2×6) with...

In database applications, access control security layers are mostly developed from tools provided by vendors of database management systems and deployed in the same servers containing the data to be protected. This solution conveys several drawbacks. Among them we emphasize: 1) if policies are complex, their enforcement can lead to performance decay of database servers; 2) when modifications in...
