Model Transformation Technologies in the Context of Modelling Software Systems

Programming technologies have improved continuously during the last decades, but from an Information Systems perspective, some well-known problems associated to the design and implementation of an Information Systems persists. Object-Oriented Methods, Formal Specification Languages, Component-Based Software Production... This is just a very short list of technologies proposed to solve a very old and, at the same time, very well-known problem: how to produce software of quality. Programming has been the key task during the last 40 years, and the results have not been successful yet. This work will explore the need of facing a sound software production process from a different perspective: the non-programming perspective, where by non-programming we mainly mean modeling. Instead of talking about Extreme Programming, we will introduce a Extreme Non-Programming (Extreme Modeling-Oriented) approach. We will base our ideas on the intensive work done during the last years, oriented to the objective of generating code from a higher-level system specification, normally represented as a Conceptual Schema. Nowadays, though, the hip around MDA has given a new push to these strategies. New methods propose sound model transformations which cover all the different steps of a sound software production process from an Information Systems Engineering point of view. This must include Organizational Modeling, Requirements Engineering, Conceptual Modeling and Model-Based Code Generation techniques. In this context, it seems that the time of Model Transformation Technologies is finally here..

Extreme Programming: Maestro Style

"Extreme Programming: Maestro Style" is the name of a computer programming methodology that has evolved as a custom version of a methodology, called extreme programming that has been practiced in the software industry since the late 1990s. The name of this version reflects its origin in the work of the Maestro team at NASA's Jet Propulsion Laboratory that develops software for Mars exploration missions. Extreme programming is oriented toward agile development of software resting on values of simplicity, communication, testing, and aggressiveness. Extreme programming involves use of methods of rapidly building and disseminating institutional knowledge among members of a computer-programming team to give all the members a shared view that matches the view of the customers for whom the software system is to be developed. Extreme programming includes frequent planning by programmers in collaboration with customers, continually examining and rewriting code in striving for the simplest workable software designs, a system metaphor (basically, an abstraction of the system that provides easy-to-remember software-naming conventions and insight into the architecture of the system), programmers working in pairs, adherence to a set of coding standards, collaboration of customers and programmers, frequent verbal communication, frequent releases of software in small increments of development, repeated testing of the developmental software by both programmers and customers, and continuous interaction between the team and the customers. The environment in which the Maestro team works requires the team to quickly adapt to changing needs of its customers. In addition, the team cannot afford to accept unnecessary development risk. Extreme programming enables the Maestro team to remain agile and provide high-quality software and service to its customers. However, several factors in the Maestro environment have made it necessary to modify some of the conventional extreme-programming practices. The single most influential of these factors is that continuous interaction between customers and programmers is not feasible

Diharapkan dengan adanya sistem ini akan mempermudah pekerjaan staff dan karyawan setiap jurusan dalam melakukan pengecekan ketersediaan alat praktek, dan mencatat alat praktek masuk, keluar atau rusak serta dapat membuat laporan yang akurat.   Kata kunci: extreme programming, persediaan alat praktek, sistem informasi   Abstract: Technological developments that occur at this time can be utilized with additional knowledge and quality human resources to create a system that helps the work of staff, and employees of each department in schools, especially in the supply of practical tools. The Practice Equipment Inventory System at SMK Taruna Bangsa still uses the manual system. This makes it difficult to find data on the availability of practical tools and record data of practical tools that are in, out, or damaged if necessary and the principal does not know what practical tools are in, out or damaged and is less accurate in making reports. The main objective in this research is to build an information system in a practical tool inventory system. The development method used is Extreme Programming because it is to improve the quality of the system when changes in user needs occur. It is expected that with this system will facilitate the work of staff and employees of each department in checking the availability of practical tools, and record practice tools in, out or damaged and can make an accurate report.   Keywords: extreme programming, information system, inventory of practice tools &nbsp

The media and advertising : a table of two-sided markets

Media industries are important drivers of popular culture. A large fraction of leisure time is devoted to radio, magazines, newspapers, the Internet, and television (the illustrative example henceforth). Most advertising expenditures are incurred for these media. They are also mainly supported by advertising revenue. Early work stressed possible market failures in program dupplication and catering to the Lowest Common Denominator, indicating lack of cultual diversisty and quality. The business model for most media industries is underscored by advertisers’ demand to reach prospectie customers. This business model has important impllications for performance in the market since viewer sovereignty is indirect. Viewers are attracted by programming, though they dislike the ads it carries, and advertisers want viewers as potential consumers. The two sides are coordinated by broadcasters (or “platforms”) that choose ad levels and program types, and advertising finances the programming. Competition for viewers of the demographics most desired by advertisers implies that programming choices will be biased towards the tastes of those with such demographics. The ability to use subscription pricing may help improve performance by catering to the tastes of those otherwise under-represented, though higher full prices tend to favor broadcasters at the expense of viewers and advertisers. If advertising demand is weak, program equilibrium porgram selection may be too extreme as broadcasters strive to avoid ruinous subscription price competition, but strong advertising demand may lead to strong competition for viewers and hence minimum differentiation (“la pensée unique”). Markets (such as newspapers) with a high proportion of ad-lovers may be served only by monopoly due to a circulation spiral : advertisers want to place ads in the paper with most readers, but readers want to buy the paper with more ads.Advertising finance; two-sided markets; platform competition
