    The purpose of this project is to design a system for UTP Security Department, fnformation Resource Centre Department and finance Department specifically for the administration of students and staffs' administration management. The system will be web - based applications that can be executed using normal web browser for inter - platform capabilities. The project is divided into two terms, first the research on clearance system for final semester student and second development on the Online Clearance System (OC System). Research on the OC System will be based on the problem statement and objective of the project while the research for the current clearance system for fmal semester at UTP is the support idea for the project. This document also gives further information about the system in the literature review/theory section. This section includes the features of the system, the benefits from using the system, and the data flow diagram of the intended system. Part of the Final Year Project, student manage to get known with the business environment on how they manage their database, clearance system and the performance of the staff. In using Online Clearance System (OC System) give the best solution for the staff as the database plays an important asset for the staff. l would use distributed database in my system.A distributed database is a database that is under the control of a central database management system in which storage devices are not all attached to a common CPU. It may be stored in multiple computers located in the same physical location, or may be dispersed over a network of interconnected computers. Collections of data (eg. in a database) can be distributed across multiple physical locations. A distributed database is distributed into separate partitions/fragments.

    methBLAST and methPrimerDB: web-tools for PCR based methylation analysis

    BACKGROUND: DNA methylation plays an important role in development and tumorigenesis by epigenetic modification and silencing of critical genes. The development of PCR-based methylation assays on bisulphite modified DNA heralded a breakthrough in speed and sensitivity for gene methylation analysis. Despite this technological advancement, these approaches require a cumbersome gene by gene primer design and experimental validation. Bisulphite DNA modification results in sequence alterations (all unmethylated cytosines are converted into uracils) and a general sequence complexity reduction as cytosines become underrepresented. Consequently, standard BLAST sequence homology searches cannot be applied to search for specific methylation primers. RESULTS: To address this problem we developed methBLAST, a sequence similarity search program, based on the original BLAST algorithm but querying in silico bisulphite modified genome sequences to evaluate oligonucleotide sequence similarities. Apart from the primer specificity analysis tool, we have also developed a public database termed methPrimerDB for the storage and retrieval of validated PCR based methylation assays. The web interface allows free public access to perform methBLAST searches or database queries and to submit user based information. Database records can be searched by gene symbol, nucleotide sequence, analytical method used, Entrez Gene or methPrimerDB identifier, and submitter's name. Each record contains a link to Entrez Gene and PubMed to retrieve additional information on the gene, its genomic context and the article in which the methylation assay was described. To assure and maintain data integrity and accuracy, the database is linked to other reference databases. Currently, the database contains primer records for the most popular PCR-based methylation analysis methods to study human, mouse and rat epigenetic modifications. methPrimerDB and methBLAST are available at and . CONCLUSION: We have developed two integrated and freely available web-tools for PCR based methylation analysis. methBLAST allows in silico assessment of primer specificity in PCR based methylation assays that can be stored in the methPrimerDB database, which provides a search portal for validated methylation assays

    Building online shopping website based on ASP.NET and SQL Server

    This project aimed to develop an online shopping website prototype selling mainly Asian food and groceries on the Internet. The website includes both a front-end portal for customers, and a back-end management system used by system administrators to manage the website in the background. The website was named Asian Online. It was designed for people who prefer online shop-ping of Asian items at home in the Helsinki area. The portal was developed using ASP.NET framework and written in C# language. The back-end system was developed using Microsoft SQL Server 2008 as database. Visual Studio .NET provided various kinds of ASP.NET controls. As a result, the website was developed and most functions for online shopping were implemented. Furthermore, people living in Helsinki can buy their favorite products online. More Finnish people are offered a platform to become familiar with oriental diet and culture. For further development, market research in Helsinki is necessary before the website will be formally established
