Research on material characteristics dependency modeling.
No full textThe aim of this work is to develop a versatile web system of material characteristics. A number of criteria were settled down after analysis of the similar web and desktop materials characteristics dependency systems. Few of them are: wide spectrum of materials, user-friendly user interface, web service function, possibility to extend usability to mobile devices, diagram view of the calculations results. All criteria is written down on a table number 1. System functionality was divided into four functional set according to user types. Unregistered users, registered users, administrators and external systems. Unregistered users have all functionality of the system but they cannot save queries only download the last one. Registered users inherits all unregistered users functionality besides have user‘s control panel. Administrators can only administrate system and users. External systems uses material characteristics system functionality via web service. Core software for the system was selected to ensure simple system scalability. System development tools were selected after technical analysis: MySQL database, Apache Server and PHP programming language
Personal data analysis and generation of a social network.
No full textThe main goal of this work was to develop a method that enables collect, analyze personal data and generate social network according data. Variety of sources can be used to collect data, such as academic publications database, dating websites. According to collected data, social network links are generated. Social network links and nodes are defined by the FOAF standard and stored in database. User may visually study generated social network, or some selected part of it, perform various calculations and find characteristics. This method combines software, that is used to embody above defined process. For data collection and analysis there is used tool, custom-made for this method. Collected data is stored in MSSQL relational database management system and visually displayed using tool Graphviz. This process and software parts are controlled by user-friendly visual application, developed using ASP.NET technology
Data transfer between DBMS and mobile device research.
No full textDatabase is one the main object in the informatics systems, which is usually realized relational database management systems (DBMS) basis. In order to achieve similar functionality and performance of desktop systems for informational mobile system we have to choose a suitable data synchronization method. This work investigates the exchange of data between the DBMS and the mobile device and methods of determining factors for their choice. In this task are pending tasks: analyze the data exchange between the DBMS and the mobile device and methods of formulating the criteria that determine the decision-making, the choice of data-exchange method; allow the exchange of data between the DBMS and the mobile device choice process. According to the literary analysis criteria were formulated, which affect the choice of methods for data exchange between the remote DBMS and the mobile device. According to the criteria were made data exchange methods for the choice process. The process provides the graphical notation with the accompanying detailed description. Additionally, the work carried out in remote data access and direct remote database using data exchange methods for the experimental performance research. For experiments were designed and developed software. The research was conducted using a set of 5 database tables and data operations which processed from 100 to 100 000 entries in one transaction. Experiment helped to establish two further criteria, which leads to the exchange of data between the DBMS and the mobile device selection method. These criteria were added to the proposed data exchange process. The proposed process, if necessary, can be extended IS developers
Trust of weblog records method development and research.
No full textThe main aim of this work is to create the system of weblog trust. The system will offer to user subjective evaluation about the article. To calculate the subjective evaluation there is used social network. There are users, who evaluates articles according the system of evaluation. The same time they form network of trust. Estimators doesn‘t know each other directly. There comes main question, how to calculate trust of unfamiliar users. In this study there will be elaborating algorithms of users intertrust and right selection. To TidalTrust algorithm, there will be offered extention, which solves the main problem of time counting. Using calculated algorithm of users intertrust there will be offered approach of calculation, which gives us the recomendationt of article trust
Templates based business rules specification methods and manipulation research.
No full textIn this work there is analyzed business rules` conception, ways of their classification and possibilities to use them in order to realize different needs, how business rules are specified and how you can manipulate them. The main aim of this work is to explore rules Blaze Advisor, to analyze business rules specification principles, by using objectively oriented SRL language and opportunities to use them on the ground of inner advisor components designed for business rules realization. After the detailed analysis it was noticed that there are defects, which don`t let effectively model business rules and narrow the access enterprises representatives to them, trying to eliminate the defects by suggested methods, which would present a more flexible way to create business rules and guide, which would ensure the possibility for business representatives themselves to participate in the realization and creation stage without IT specialists immediate help. Realizing the system by the suggested method, there is a possibility for business representatives to guide business processes, by changing business rules` permissible parts, in this way all the program`s and its realization logic and acceptable decisions. It`s easy to conform business processes to the changeable conditions, which in one or another way make influence to the enterprise`s activity by reducing the enterprise`s costs
Feasibility study of Gherkin tests generation from requirements.
No full textTesting is becoming a concurrent part of the software development. To ensure the testing quality and rapid testing in the future, testing scenarios need to be prepared properly. These scenarios are made from software requirements, but requirements tend to change often, which cause the need to update the testing scenarios. This process cost time and it is possible to lose the important data. Because of that the best decision for this problem could be the automated generation of test cases. The Gherkin tests generation was chosen because this language is easily understandable and could be used to create the automated tests. Experimental investigation has shown that the automated tests generation would improve the work for development teams. The analysis has shown that only one solution for Gherkin generation from requirements is realized. As a result of this thesis, four algorithms where suggested to generate Gherkin tests from the requirements: from the activity diagram, from sequences diagram, from tables and job stories. These algorithms have restrictions, however they can be improved for more complex structures of the requirements
Veiklos žodynų ir veiklos taisyklių semantika grindžiamas veiklos procesų vaizdavimas.
No full textThe development of an information system starts with business process modeling and identification of the business domain vocabulary and rules. In order to develop complete and comprehensive business process specification, it is appropriate to use several business modeling standards that deal with different business aspects and provide any participant with an opportunity to choose the most acceptable method of business representation. The selection of the most acceptable business representation method may speed up and improve communication between domain participants thus helping them avoid misunderstandings due to incorrect interpretations or misuse of terms, especially when the model is large and, therefore, difficult to read. This dissertation is devoted to integrating business process and business rules modeling standards in order to get a comprehensive and consistent business process specification. This decision is based on BPMN2 and SBVR modeling standards as the analysis showed that complex application of these two standards allows the best representation of real world objects and processes. Transformation of graphical business process models to business vocabularies and business rules models was implemented in order to ensure the compatibility of these two models
The analysis of data filtration and selection solutions.
