This project is a movie theater order system. This system allows people to get movie information and purchase tickets on the Internet. This project is based on a Model-View-Controller (MVC) architecture, which introduces a controller servlet to provide a single point of entry to the web system and encourages more reuse and extensibility of the code.

The purpose of this project is to design, build and implement a web application system for the Olympiad delegation registration. All the pages and user registration information will be stored in a PostgreSQL database and retrieved by JAVA Servlet and JDBC (JAVA Database Connectivity). The main purpose of this project is to provide an easy-to-register and web-base communication evironment for the National Olympic Committes (NOC) and the Organizing Committee for the Olympic Games (OCOG).

Whenever one designs a new database system, an Entity-Relationship Diagram (ER diagram) is always needed to present the structure of this database. Using the graphically well-arranged ER Diagram helps you to easily understand the entities, attributes, domains, primary keys, foreign keys, constraints, and relationships inside a database. This data-modeling tool is an ideal choice for companies and developers.

This project "Designing Secure, Java Based Online Registration Systems to Meet Peak Load Performance Targets" is a simulation of a Web-based exposition management system plus a performance testing procedure to examine this web application.

The purpose of this project is to update the architecture and design of the California State University San Bernardino Graduate Advisor System. This system allows potential students into the Master of Science degree program in Computer Science to complete their application online.

Software as a service is an emerging but important aspect of the web. WebServices play a vital role in providing it. Web Services are commonly provided in one of two architectural styles: a "REpresentational State Transfer" (REST), or using the "Simple Object Access Protocol" (SOAP.) Originally most web content was text and small images. But more recent services involve complex data structures including text, images, audio, and video. The task of optimizing data to provide delivery of these structures is a complex one, involving both theoretical and practical aspects. In this thesis work, I have considered two architectures developed in the REST architectural style and tested them on mixes of data types (plain text, image, audio) being retrieved from a file system or database. The payload which carries the actual content of a data transmission process can either be in Extensible Markup Language (XML) or JavaScript Object Notation (JSON). Both of these language notations are widely used. The two architectures used in this thesis work are titled as Scenario 1 and Scenario 2. Scenario 1 proposes two different cases for storing, retrieving and presenting the data via a REST web service. We investigate the question of what is the best way to provide different data types (image, audio) via REST Web Service. Payload size for JSON and XML are compared. Scenario 2 proposes an enhanced and optimized architecture which is derived from the pros of the first two cases in Scenario 1. The proposed architecture is best suited for retrieving and serving non-homogeneous data as a service in a homogenous environment. This thesis is composed of theoretical and practical parts. The theory part contains the design and principles of REST architecture. The practical part has a Web Service provider and consumer model developed in Java. The practical part is developed using the Spring MVC framework and Apache CXF, which provides an implementation using JAX-RS, the Java API for RESTful services. A glossary of acronyms used in this thesis appears in the appendix on page 101.

Java is a very commonly used computer programming language, although its use amongst the scientific and High Performance Computing (HPC) communities remains relatively low. In this thesis, the option of using Java for developing scientific applications intended for execution in HPC environments is investigated. The data reduction pipeline for the Gaia space astronomy mission is an example of a large software project that has been written in Java, and will run in HPC environments. The efficient execution of the Gaia data reduction pipeline was one of the main motivations behind this thesis, although this thesis largely remains a general investigation into the use of Java in HPC. HPC is a fast changing field, in terms of hardware, software, and the scale of the problems that are being tackled. Amongst the most significant trends in HPC in recent years have been the increase in the number of cores per computing node, and the increase in the size of datasets that must be processed. A significant challenge in HPC is ensuring that data is made available in a particular node, when a core is ready to process it, thereby avoiding deadtime and providing high throughput. One danger to throughput is a decrease in the performance of shared storage devices, as the number of concurrent processes that are accessing those devices increases. Given the trends mentioned above, efficient data communication is very important for many applications running in HPC environments. In this thesis, we present an investigation into the current options for providing efficient data communication to Java applications in HPC environments. We investigate a number of implementations of Message Passing in Java (MPJ) and compare their performance. We present a new communication middleware application, called MPJ-Cache. This middleware makes use of an underlying implementation of Message-Passing in Java (MPJ), and adds prefetching, caching, and file-splitting functionality. It presents application developers with a high-level API, thus providing high-performance, as well as enabling high productivity amongst application developers. We compare the aggregate data rate that can be achieved though the use of this middleware, against that which can be achieved though direct access of a high performance shared storage device (GPFS), while distributing data amongst the nodes of a computer cluster. The use of MPJ-Cache has shown to provide an aggregate data rate of up to 103Gbps. Java applications are executed within a Java Virtual Machine (JVM), which is a managed runtime environment. The execution of applications within such a runtime environment is very different from the execution of native code, that was compiled ahead-of-time. The Java runtime environment consists of several sophisticated components, including the core runtime system, a garbage collector and a Just-In-Time (JIT) compiler. Modern JVMs strive to provide out-of-the-box high-performance, however in some situations, users may want to tune the JVM to better suit the behaviour and needs of a particular application. In order to do this, a profile of the target application should be obtained.

This project will simulate an online real estate company using JSP, Java Servlet and JavaBean technology.
