Business Rules – Important Artefacts of Software Development
Abstract: In today’s business environment, characterized by competition enhancement, it is very important for an organization to be able to face changes. Therefore, the need for achieving and maintaining some competition advantages, led to the situation where the identification, specification and formalization of business politics and objectives became major concerns for many organizations. Literature refers to such politics and objectives as business rules. This article aims to analyze various business rules definitions and classifications schemas, from both business and information systems perspectives.
The Franchise Deductible Policy
Abstract: The paper presents applications of credibility theory dealing with real life situations, and implemented on real insurance portfolios. Though more examples could be given, we limit ourselves to the introduction of a franchise deductible policy. In this example we try to demonstrate what kind of data is needed to apply credibility theory. The example shows that credibility theory is really a useful tool-perhaps the only existing tool-for such insurance ap-plications.
Insurance Problems Obtained Using the Software Package Crac 2.0

All numerical results in this paper were obtained using the software package CRAC 2.0, which uses Jewell’s hierarchical model. Examples of the output of the program will be given and discussed. This will give more insight and understanding of the theoretical aspects and will point the way to the practical possibilities of the credibility models.
Abstract: Developing new software products brings into equation a lot of challenges because a software product is characterized by invisibility, flexibility and complexity per unit effort. To set up a reliable business plan in new software product development, an accurate evaluation of product market utility, of the expected quality and of the necessary budget to support ap-propriately the development process is required. Because software products are “invisible” during the analysis, design and implementation phases, innovative approaches are required to handle properly both product and related-budget formulation. This paper describes a novel methodology for software product innovation, planning and control, capable to manage at superior levels the development process of complex software products. The exemplification on a software application for quality cost management is afterwards presented.

The E-business Strategy Management
Abstract: The intensive use of Information and Communication Technology and that of knowl-edge leads the organization towards another method of doing business (electronic business, mobile business, i-business) and towards new organizational patterns (virtual organizations, network organizations). Within this context, each organization must assure an adequate man-agement for each phase of the transformation. Taking into account the diversity of electronic business patterns, the theory at the base of each of them, the different patterns of measuring performance and also the strategic control instruments, we present a development environ-ment of an evaluation and control system to assist managers in formulating, optimizing and implementation of e-business strategies, in operations management and monitoring of per-formance.

Financial Diagnosis Expert System
Abstract: Specialists consider a financial diagnosis necessary for measuring the profitable-ness of invested capital and for estimating the economic and financial equilibrium, which has a certain influence on the economic, financial, and bankruptcy risk rate. Thus, the main pur-pose of any financial diagnosis is to point out the financial state of the company in order to identify possible causes and effects. A financial diagnosis starts with determining and inter-preting a set of economic- financial indicators, which are calculated based on the financial balance sheet.
Certification of Distributed Informatics Applications
Abstract: The distributed application concept is defined. The efficiency of distributed applications is strictly dependent on their level of quality. The quality requirements and the way to point out the effective levels that the traits distributed applications have are stated. The certification of distributed applications is validated by passing through stages with detailed and well-defined tasks.
Securing the Organization with Network Behavior Analysis
Abstract: To protect from the ever-growing number of security threats, organizations are look-ing to implement more and more sophisticated security solutions. This is a normal path, since the traditional means of protecting the enterprise, by using firewalls, cannot offer the desired protection level. Tools like intrusion detection systems and intrusion prevention systems are such examples. Another such technology is the Network Behavior Analysis (NBA), which can be implemented as a stand-alone system or included in IDS/IPS or other security tools. The article outlines the NBA technology with its features and limitations and presents the current situation and the possible uses of this technology.
Feedback from Research and Teaching Functions of Higher Education
Abstract: In the continuous process of expansion, higher education tend to interpret these chal-lenges differently and tries to offer several master degree programs for level of degrees and life long learning. This paper show a model for a feedback from research and teaching func-tions, based on several master degrees programs and students’ opinions about level of mas-ter degrees educations and job perspective. Our proposal is focused on Jakarta Struts Framework since this solution offers more flexibility, portability and interoperability in other applications. This framework validate knowledge management proposal for academia.
Network-Based Modelling and Geographic Information Systems
Abstract: One of the latest developments of the location theory envisages the territorial net-works, which are considered the most complex type of clusters (compared to pure agglomera-tion and industrial district), more and more researchers concentrating on the systemic ap-proach of these networks and the possibilities to develop adequate models for their analysis. The Geographic Information Systems represent one of the most useful tools in this respect. This paper proposes an inquiry into the network definition and typology, pointing out the pos-sibilities to use the neural network- based models in order to study the territorial relation-ships. The role of Geographic Information System (GIS) as one of the instruments that can provide valuable information in data analyses is also considered.
Reducing Software Projects Duration Using C#
Abstract: This paper analyzes the impact of using the C# language on project development du-ration. A set of duration estimation techniques are explained, the difficulties of estimating software project duration are enumerated and the factors that negatively impact the duration of a software project are analyzed. The technical advantages of C# language are presented as factors that reduce project complexity and duration.
Internet Data Validation
Abstract: In Business Information Systems, data validation is the process of ensuring that a program operates on clean, correct and useful data. It uses routines, often called validation rules, that check for correctness or meaningfulness of data that are input to the system.
Business Intelligence Support Systems and Infrastructures
Abstract: Business Intelligence (BI) is the most popular concept in today’s Decision Support Technologies. BI offer sophisticated information analysis and information discovery tech-nologies (Data Warehouse, OLAP, Data Mining) that are designed to handle and process the complex business information associated with today’s business environment. Only a revolu-tionary Business Intelligence solution, like the proposed portal-based, can solve the complex issues faced when evaluating decision support applications and ensure the availability of any business-critical information. In this paper we recommend some BI solutions in order to cre-ate a collaborative business environment.
Abstract: The regional development as main pillar of the European cohesion policy is a very important pole of creativity and innovation, contributing to the increase of the competitive-ness, goal of the Lisbon strategy. In this view, the regional development strategy and the con-crete measures of its implementation represent the frame for the regional and sectoral pro-jects development. The real impact of the implementation of the regional strategy could be evaluated only by a wide process of gathering the regional actors’ views and opinions. A very efficient tool for the evaluation process is the integrated democratic-centric driver for the re-gional development, which offers the virtual frame for a large access to regional strategies implementation and for the wide expression of the regional actors’ satisfaction, related to the regional projects and their implementation. The development of such an integrated frame-work needs to merge different viewpoints and technologies in order to create a regional por-tal for the wide dissemination of the regional programmes according to the development strategy, to ensure their transparency, to increase the opportunities to implement more inno-vative projects, and to collect the regional actors’ opinions on the effectiveness of the pro-jects implementation and the regional strategy objectives fulfillment.
IT Projects Performance Indicators
Abstract: Many software and IT projects fail or succeed in achieving theirs objectives because dif-ferent causes of which the management of the projects has a high weight. In order to have suc-cessfully projects, lessons learned have to be used, historical data to be collected and metrics and indicators have to be computed and used to compare them with past projects and avoid fail-ure to happen. This paper presents some indicators that can be used for the measurement of IT project management performances.
