With increasing urbanization and population growth, humankind faces multiple environmental challenges. Stresses on limited resources, especially water resources, are now greater than ever before. Watershed monitoring and management are important components of programs to abate water resource stresses. The increasing water quantity and quality monitoring has produced a need for better data management techniques to manage the vast amount of watershed monitoring data being observed. These data must be stored, error checked, manipulated, retrieved and shared with the watershed management community. The web-based data visualization and analysis technology has played a critical role in all aspects of watershed management. Especially in recent years, computer-assisted data analysis has matured enormously. This maturing technology makes web-based visualization and analysis technology change its role to become an integrated system which combines applications of databases, and internet technology. The main objective of this study is to develop a prototype system which has ability of data visualization and analysis. Microsoft SQL Server is used to build a comprehensive database, which includes all datasets collected by OWML. A Web-Based Data Visualization and Analysis System which provides an integrated interface for permitted users to explore, analyze and download data has been developed. / Master of Science

Legacy systems are usually expensive to maintain, and they quickly become outdated in a fast changing industry with new requirements and technologies. However, replacing an old system with a complete new one could prove both costly and time consuming, and therefore the method of reengineering could present itself as a beneficial alternative. There is a lack of practice-based research in relation to the implementation of software reengineering. The main purpose of this thesis is therefore to recognize key aspects on how to reengineer web-based IT systems in a modern, easy-to-maintain and business-enhancing manner. A case study has been carried out, a reengineering of a legacy system used for product selection at Grindex AB, a Swedish submersible pump supplier and manufacturer. The process includes three stages, firstly a thorough analysis of the legacy system has been carried out, secondly interviews were conducted in order to identify new requirements, and lastly a new system was developed by Struts 2, Spring MVC, Spring, Hibernate in Java and a relationship database of MySQL. The author is presenting six areas of consideration – architecture, function, interface, language, data storage and algorithm – in relation to the software reengineering life cycle, and with a comparison between the legacy system and the reengineered system. / Legacy system är ofta kostsamma att underhålla och de blir fort förlegade i en industri i snabb förändring med nya krav och teknologier. Men det kan samtidigt visa sig kostsamt och tidskrävande att byta ut ett gammalt system mot ett helt nytt. Mot denna bakgrund skulle metoden reegineering kunna utgöra ett fördelaktigt alternativ. Den praktiskt orienterade forskning i relation till programvaruutveckling genom reegineering är knapphändig. Det främsta målet med denna avhandling är därför att ringa in viktiga aspekter sett till hur webbaserade ITsystem skulle kunna reegineras på ett modernt sätt, enkla att underhålla och företagsfrämjande. En studie har genomförts, en reegineering av ett legacysystem som använts för produktval på Gridex AB, en svensk leverantör och tillverkare av dränkbara pumpar. Processen omfattar tre delar. Först genomfördes en grundlig analys av legacy systemet, sedan genomfördes intervjuer för att identifiera nya krav och avslutningsvis utvecklades ett nytt system med Struts 2, Spring MVC, Spring, Hibernate i Java och en relationsdatabas i MySQL. Författaren presenterar sex områden att beakta – arkitektur, funktion, gränssnitt, språk, datalagring and algoritm – i relation till programvarureenginderingens livscykel och med en jämförelse mellan legacysystemet och det reegingerade systemet.

Structural design of reinforced concrete structures requires involvement of many engineers who contribute to a single project. During the design process engineers have to exchange wide variety of information. Unmanaged data exchange may result in loss of resources. Developing a data model and setting up protocols for the management of data related to various structural design tasks can help to improve the quality of the structural design. In this study, an object oriented data model was developed for reinforced concrete beams. Geometry of the structure, detailed shape and placement of the reinforcement, and design specific information for beams were defined in the data model. Design code based computations are facilitated by developing a code library. Another focus of this study is developing a web based, platform independent data management and multi-user framework for structural design and detailing of reinforced concrete frames. The framework allows simultaneous design of a structure by multiple engineers. XML Web Services technology was utilized for the central management of design data. Design data was kept as XML files. Information was exchanged between the server and the engineer on a per-request basis. To design a beam strip, the engineer connects to the server and chooses a series of connected beams. The strip that is selected is locked for modifications of other engineers to prevent any data loss and unnecessary duplicate efforts. When the engineer finalizes the design of a beam strip, data is updated on the server and the lock for this strip is released. Between these requests no active connection is required between the engineer and the server. As a final task, the framework can produce structural CAD drawings in DXF format.

In design and detailing of a reinforced concrete frame project, there are many engineers who contribute a single project. Wide variety of information is exchanged between these engineers in design and detailing stages. If the coordination between engineers is not performed sufficiently, data exchange may result in loss of important information that may cause inadequate design and detailing of a structure. Thus, a data model developed for different stages of design and detailing of reinforced concrete structure can facilitate the data exchange among engineers and help improving the quality of structural design. In this study, an object oriented data model was developed for the design and detailing of reinforced concrete columns and beam column joints. The geometry of the structure, amount, shape and placement of reinforcement were defined in this data model. In addition to these, classes that facilitate the design and detailing of reinforced concrete columns and beam column joints according to a building codes were also developed. Another focus of this study is to develop a web based, platform independent data management and multi-user framework for structural design and detailing of reinforced concrete frames. The framework allows simultaneous design of a structure by multiple engineers. XML Web Services technology was utilized for the web based environment in such a way that the design related data was stored and managed centrally by the server in XML files. As a final step, CAD drawings of column reinforcement details in DXF format are prepared.
