Chatbots platform are used by consumers worldwide for integrating it with backend services . It is still difficult to build and deploy chatbots developers need to handle the coordination of the backend services to build the chatbot interface, integrate the chatbot with external services, and worry about extensibility, scalability, and maintenance. The serverless architecture could be ideal platform to build the chatbot.

Politechniki 11, 90-924 Łódź, Poland, e-mail: [email protected], [email protected] http://www.dmcs.p.lodz.pl Abstract: This paper describes how to design content management system using the newest web-based techniques. It contains helpful information that can be used during selecting programming language. It introduces multi layer architecture with description and functionality of each layer. It provides description of Model View Controller pattern and how to use it in multi-layer application design. It shows the most powerful Java frameworks that can be applied for each layer and how to connect them in simple way, using Inversion of Control container. It shows power of Spring Framework as business layer, Hibernate as integration layer and ZK Ajax as presentation layer. It proves, that Java combined with applicable libraries can be very powerful tool in good hands. Keywords: CMS, JEE, Spring, Hibernate, AJAX. 1.

Usually it is a set of web pages containing The Internet – today is the most powerful and complex forms and modules. popular information media. What was impossible The primary task of the CMS platform is even few years ago is now available by “clicking separation of data content from presentation (the the mouse”.

Physical separation of data concerns Examples: • Presentation (UI) • Application Processing • Data Management Why split into layers? OSI Model Why split into layers? Separation of concerns! A change to one layer can have no bearing on the rest of the model e.g. Fiberoptic instead of Coax at the PHY layer OSI Model How does this apply to mobile? Application designers often want separation of UI and logic! Three tier architecture These software engineering abstractions relate to the MV* architectures that are common in mobile computing systems Model View Controller (MVC) Model View Controller 1 1Krasner 1988 Definitions Model: Models are those components of the system application that actually do the work View: Display aspects of the models Controller: Used to send messages to the model, provide interface between model, views, and UI devices.

Client Server Communications Middleware Components
1 Assistant lecturer Ahmed S. Kareem CLIENT SERVER COMMUNICATIONS MIDDLEWARE COMPONENTS The communication middleware software provides the means through which clients and servers communicate to perform specific actions. It also provides specialized services to the client process that insulates the front-end applications programmer from the internal working of the database server and network protocols. In the past, applications programmers had to write code that would directly interface with specific database language (generally a version of SQL) and the specific network protocol used by the database server. Multitier architecture In software engineering, multi-tier architecture (often referred to as n-tier architecture) is a client–server architecture in which the presentation, the application processing, and the data management are logically separate processes. For example, an application that uses middleware to service data requests between a user and a database employs multi-tier architecture. The most widespread use of multi-tier architecture is the three-tier architecture. N-tier application architecture provides a model for developers to create a flexible and reusable application. By breaking up an application into tiers, developers only have to modify or add a specific layer, rather than have to rewrite the entire application over. There should be a presentation tier, a business or data access tier, and a data tier. The concepts of layer and tier are often used interchangeably. However, one fairly common point of view is that there is indeed a difference, and that a layer is a logical structuring mechanism for the elements that make up the software solution, while a tier is a physical structuring mechanism for the system infrastructure. -

Pdas and Smartphones in the Classroom Teaching and Technology Trends Symposium March 30, 2007 Jimmy D
PDAs and Smartphones in the Classroom Teaching and Technology Trends Symposium March 30, 2007 Jimmy D. Clark, Instructional Design Specialist Introduction Figure 1: Mobile Devices Today’s young learners use mobile devices such as cell phones, PDAs, MP3 players, and GPS devices every day. They enjoy learning as part of a group or team, or even in a “smartmob” or “learning swarm.” They play computer games, interact constantly with each other on websites such as Facebook and MySpace, and wish their college learning experience matched the learning they do in their everyday lives. Mobile learning technologies give them this opportunity. In this workshop we will focus on how PDAs and smartphones facilitate learning in today’s new teaching and learning environment. What You Will Learn in this Workshop In this workshop you will learn what mobile learning is: its history, some of the advantages of mobile learning, and about some of the tools used in mobile learning. You will also learn about the features of a PDA, its history, and the ways they are used in education. We will also talk about the challenges of using PDAs in education, with special emphasis on accessibility issues. In the last part of our discussion of PDAs we will talk about future trends in the use of PDAs in education. In the section on smartphones we will discuss what a smartphone is, its features, operating systems, the history of the smartphone, the reasons they are popular in education, and future trends in smartphones. This will not be a hands-on workshop. Goals and Objectives for this Workshop The goals and objectives for this workshop are: 1. -
Design Patterns Past and Future
Proceedings of Informing Science & IT Education Conference (InSITE) 2011 Design Patterns Past and Future Aleksandar Bulajic Metropolitan University, Belgrade, Serbia [email protected]; [email protected] Abstract A very important part of the software development process is service or component internal de- sign and implementation. Design Patterns (Gamma et al., 1995) provide list of the common pat- terns used in the object-oriented software design process. The primary goal of the Design Patterns is to reuse good practice in the design of new developed components or applications. Another important reason of using Design Patterns is improving common application design understand- ing and reducing communication overhead by reusing the same generic names for implemented solution. Patterns are designed to capture best practice in a specific domain. A pattern is supposed to present a problem and a solution that is supported by an example. It is always worth to listen to an expert advice, but keep in mind that common sense should decide about particular implemen- tation, even in case when are used already proven Design Patterns. Critical view and frequent and well designed testing would give an answer about design validity and a quality. Design Patterns are templates and cannot be blindly copied. Each design pattern records design idea and shall be adapted to particular implementation. Using time to research and analyze existing solutions is recommendation supported by large number of experts and authorities and fits very well in the pattern basic philosophy; reuse solution that you know has been successfully implemented in the past. Sections 2 and 3 are dedicated to the Design Patterns history and theory as well as literature sur- vey. -
