Serverless computing is a new and still evolving type of cloud computing, which brings a new approach to the development of information systems. The main idea of serverless is to give an approach of doing computing without dealing with a server to a user. Such approach allows to reduce the cost of the system building and system support. It allows small companies to concentrate on their own system designing instead of thinking about infrastructure building and supporting. Also, a big problem of providing the system security on high level is on cloud’s provider engineering support service. Serverless approach allows to start business quickly without huge initial investment. There is an attempt to completely analyze features, benefits and drawbacks of serverless approach, its use cases and main patterns of Serverless architecture. What is more, different providers have been analyzed.

Up to the present there has been insufficient experience in marketing natural gas in Australia to give precise opinions based upon experience. This paper therefore deals mainly with the problems to be encountered and expected methods of dealing with them.Since natural gas was first discovered, frequent comparisons have been drawn with the American industry's position and it is often suggested that this should form the pattern for Australian development. I would question whether the parallel exists to any great degree as the American industry was established and gained a firm foundation from cheap surplus supply of natural gas.Australia has begun marketing natural gas under much more difficult circumstances. It is being given no opportunity of cheap raw material to build up a load and must fight for much of its business on very narrow cost margin differentials. The American gas distributing industry was able to quickly write off conversion costs and rehabilitate its operation, placing it in a strong position for future marketing activities.Gas Purchase contracts already negotiated are a compromise of conflicting interests. Producers desire maximum well head prices, pipeliners satisfactory margins and distributors an adequate return on investment. Large volume sales are necessary for economic operation but frequently are only obtainable at rates very close to city gate prices.Large special type users, such as power houses or fertilizer plants, can provide base business but due to their special nature, are not considered in detail.Industry generally, is where the major volume sales will be obtained. The first requirement is the construction of tariffs to attract this business but which will not conflict either with existing revenue or with the various types of customers. A new approach to tariffs and special contracts is required by the distributor to meet the flexible nature of competition from the oil industry.The gas marketer must maximize the advantages of natural gas as a fuel. It is not necessary merely to have gas available at attractive prices. Australian industry is extremely conservative and potential users may need education on the true importance of fuel in their operation. Many look at the cost of the fuel only, without realising the other advantages which can be gained from the introduction of this more refined material. Even after supply has commenced, it has been found necessary to spend considerable time with customers to show how the new fuel may be used to the greatest advantage and economy.The third market area lies in domestic and commercial business. The existing traditional market of cooking and water and space heating will remain the basic load and the main requirement is to convince householders of the real value of natural gas. Domestic business is strongly influenced by personal choice and prestige value while sometimes ignoring cost and utility. Other marginal domestic markets will develop, but whilst valuable, are unlikely to provide a significant load.Commercial sales are a market for which natural gas should obtain a very high level of saturation. Its advantages in utilisation and cost are far ahead of any competitive fuel. This market however will need to be sold in a positive way.After the first market developments have taken place, it is expected that gas distributors will consider extending gas purchase contracts. Negotiations should take place under much more realistic conditions, as experience will exist to determine what is a fair basis of purchase to allow further market development to take place.

Significance However, implementation of this technology still faces multiple unresolved challenges, making the estimate appear over-optimistic. Impacts Rising consumer demand for transparent supply chains makes blockchain especially useful for fashion, food and mining sectors. Traditional databases and information systems will remain central to supply chain efficiency improvements. As the blockchain industry matures, the cost of deploying the technology will fall from its current high level.

In conditions of intense competition in a crowded market, when the struggle is for each customer and the products are customized for a very narrow marketing niche, the use of generally accepted marketing brand communications in small business is tantamount to ruin. The article substantiates that creating a brand should not be the goal of a small business, but should be an enjoyable side effect of direct marketing. The main idea of the article is that a multiple increase in prices for goods and services is possible without significant growth in the cost price in small companies by selecting the most highly profitable customers, creating an individualized marketing message and selecting the relevant message channel. The author cites some aspects of direct marketing tools, given the high information noise in the media and the "advertising blindness" of potential customers. The article contains recommendations for various types of small businesses on the use of classic offline direct marketing tools.

Software engineers make use of several computational architectures (CA) to host an application, such as desktop, web, and cloud computing architectures. As the requirements vary according to the desired CA, developers may face two problems: determining which requirement better fulfills a CA and determining which CA fulfills a given set of requirements. This paper presents a new approach based on the Cost-Value Approach (CVA). We have slightly modified the CVA method (SCVA method) and also developed a new method for choosing the most appropriate CA (MMACA method). Our results provide a set of requirements ordered by priority for each CA. Finally, we discuss the current and most appropriate CA for a real project solution.

Abstract:The development of an innovative clinical decision-support project such as the University of Minnesota’s Clinical Workstation initiative mandates the use of modern client-server network architectures. Preexisting conventional laboratory information systems (LIS) cannot be quickly replaced with client-server equivalents because of the cost and relative unavailability of such systems. Thus, embedding strategies that effectively integrate legacy information systems are needed. Our strategy led to the adoption of a multi-layered connection architecture that provides a data feed from our existing LIS to a new network-based relational database management system. By careful design, we maximize the use of open standards in our layered connection structure to provide data, requisition, or event messaging in several formats. Each layer is optimized to provide needed services to existing hospital clients and is well positioned to support future hospital network clients.

Financial Information Systems

Financial information system is an information system that provides information to individuals or groups of people, both inside and outside the company that contains financial problems and information about the flow of money for users in the company. Financial information systems are used to solve financial problems in a company, by meeting three financial principles: fast, safe, and inexpensive.Quick principle, the intention is that financial information systems must be able to provide the required data on time and can meet the needs. The Safe Principle means that the financial information system must be prepared with consideration of internal controls so that company assets are maintained. The Principle of Inexpensive, the intention is that the cost of implementing a financial information system must be reduced so that it is relatively inexpensive.Therefore we need technology media that can solve financial problems, and produce financial information to related parties quickly, safely and cheaply. One example of developing information technology today is computer technology and internet. Starting from financial problems and technological advances, the authors make a website-based financial management application to facilitate the parties that perform financial management and supervision.Method of development application program is used Waterfall method, with the following stages: Software Requirement Analysis, Software Design, Program Code Making, Testing, Support, Maintenance.

Abstract Nowadays, the growth and complexity of functionalities of current information systems, especially dynamic, distributed and heterogeneous information systems, makes the design and creation of such systems a difficult task and at the same time, strategic for businesses. A very important stage of data protection in an information system is the creation of a high level model, independent of the software, satisfying the needs of system protection and security. The process of role engineering, i.e. the identification of roles and setting up in an organization is a complex task. The paper presents the modeling and design stages in the process of role engineering in the aspect of security schema development for information systems, in particular for dynamic, distributed information systems, based on the role concept and the usage concept. Such a schema is created first of all during the design phase of a system. Two actors should cooperate with each other in this creation process, the application developer and the security administrator, to determine the minimal set of user’s roles in agreement with the security constraints that guarantee the global security coherence of the system.

Abstract Advanced jet training still relies on old concepts and solutions that are no longer efficient when considering the current and forthcoming changes in air combat. The cost of those old solutions to develop and maintain combat pilot skills are important, adding even more constraints to the training limitations. The requirement of having a trainer aircraft able to perform also light combat aircraft operational mission is adding unnecessary complexity and cost without any real operational advantages to air combat mission training. Thanks to emerging technologies, the JANUS project will study the feasibility of a brand-new concept of agile manoeuvrable training aircraft and an integrated training system, able to provide a live, virtual and constructive environment. The JANUS concept is based on a lightweight, low-cost, high energy aircraft associated to a ground based Integrated Training System providing simulated and emulated signals, simulated and real opponents, combined with real-time feedback on pilot’s physiological characteristics: traditionally embedded sensors are replaced with emulated signals, simulated opponents are proposed to the pilot, enabling out of sight engagement. JANUS is also providing new cost effective and more realistic solutions for “Red air aircraft” missions, organised in so-called “Aggressor Squadrons”.
