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.

Hibernate ORM Query Simplication Using Hibernate
2016 3rd National Foundation for Science and Technology Development Conference on Information and Computer Science Hibernate ORM Query Simplication Using Hibernate Criteria Extension (HCE) Kisman Sani M.

Kebon Jeruk Raya No. 27, Jakarta Barat, DKI Jakarta, Indonesia 11530 Jakarta, Indonesia 11530 [email protected] [email protected] Abstract— Software development time is a critical issue interfaced by a query. The software engineer will make in software development process, hibernate has been the query specified to database used. Each database widely used to increase development speed. It is used in vendor has their Structured Query Language (SQL). As database manipulation layer. This research develops a the development of software technology and most of library to simplify hibernate criteria. The library that is programming languages are object oriented, some called as Hibernate Criteria Extension (HCE) provides API functions to simplify code and easily to be used. Query engineer or software institutions try to simplify the associations can be defined by using dot. The library will query process. They try to bind object in application to automatically detect the join association(s) based on database. This approach is called as Object Relational mapping in entity class. It can also be used in restriction Mapping (ORM). ORM is a translation mechanism from and order. HCE is a hibernate wrapper library. The object to relational data, vice versa. ORM has “dialect” configuration is based on hibernate configuration. -
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. Models Models enable encapsulation Model encapsulates all data as well as methods to change them • Can change the underlying data structures without -

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. -
Develop a Simple Web Application with Apache Wicket and Apache
Develop a simple Web application with Apache Wicket and Apache Geronimo Combine Wicket, Geronimo, and Apache Derby to form an open source Java Web development platform Skill Level: Intermediate Robi Sen ([email protected]) Vice President Department 13 LLC 10 Jul 2007 Apache Wicket is an innovative Java™ Web application framework that was introduced a couple of years ago. It helps simplify Web application development by clearly separating the roles of developers and designers. It lets you remove logical code from the view layer, eliminating the need for JavaServer Pages (JSP), providing a simple plain old Java object (POJO)-centric mode of development, and removing much of the need for XML and other configuration file formats. In this tutorial, learn how to set up your system to develop a simple Web application with Wicket, using Apache Geronimo as your application server and Apache Derby as the embedded database. Section 1. Before you start This tutorial is designed for developers who have found Java frameworks, such as Struts, lacking in needed functionality. If you're interested in developing Web applications in a more object-oriented manner, where the view is clearly separated from logic and there's minimal configuration and mapping, then Wicket is for you! This tutorial walks you through the basics of how Wicket works, while using Apache Geronimo to set up a Java Platform, Enterprise Edition (Java EE) server, Web server, and embedded database in just minutes. Combining Wicket with Geronimo lets you develop data-driven, scalable Web applications using software that's all open source.

In this paper, we will discuss ten programming languages: C++, C#, Java, Groovy, JavaScript, PHP, Schalar, Scheme, Haskell and AspectJ. We summarize and compare these ten languages on ten different criterion. For example, Default more secure programming practices, Web applications development, OO-based abstraction and etc. At the end, we will give our conclusion that which languages are suitable and which are not for using in some cases. We will also provide evidence and our analysis on why some language are better than other or have advantages over the other on some criterion. 1 Introduction Since there are hundreds of programming languages existing nowadays, it is impossible and inefficient
