SECOND NATIONAL CONFERENCE ON ADVANCES IN COMPUTING AND INFORMATION TECHNOLOGY ISSN:2347-7385 Chatbot on Serverless/Lamba Architecture Nandan.A Prof.Shilpa Choudary Student, Reva University Professor, Reva University Abstract—The OpenLambda, a new, opensource The logic tier contains the code required to translate platform for building next-generation web services user actions at the presentation tier to the and applications on serverless computation. The functionality key aspects of serverless computation and that drives the application’s behavior. The data tier present numerous research challenges that consists of storage media (databases, object stores, must be, addressed in the design and caches, file systems, etc.) that hold the data relevant implementation of such systems. The study of to the application. Figure 1 shows an example of a current web applications, so as to better motivate simple three-tier application. some aspects of serverless application construction. 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.

Web-Based Content Management System
Maciej Dobecki, Wojciech Zabierowski / Computing, 2010, Vol. 9, Issue 2, 127-130 [email protected] ISSN 1727-6209 www.computingonline.net International Journal of Computing WEB-BASED CONTENT MANAGEMENT SYSTEM Maciej Dobecki, Wojciech Zabierowski Technical University of Lodz, al. 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. INTRODUCTION CMS is prepared through a simple-to-use user interface. 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”. Both small firms and global giants do way of its look). -

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. -

An over-riding requirement is that these various data managers be able to communicate with each other and provide shared access to data and
