The goal of this diploma thesis is to design and create web portal about Android devices and to make the portal logo as well. The main part of the portal is public catalog of favourite applications and games, which can be managed by registered users. Other parts of the portal will be writing articles, adding advertisement to market, adding Android devices etc. In this thesis today Android portals will be analysed and identified user's specific needs.

Theses is focused on general solution of information system design, whose part is integrated e-shop. It lay down base for easy extensible system, which predestined for constant development. Important property is acqusutuin of user data and their following research.

Speed is a very important factor in websites and other types of applications and almost all applications stores some type of data, normally in a database. For an example a blog typically saves users, posts and comments. There’s a high risk that as the amount of data in the database grows, the time for inserting and requesting specific data increases. If it takes more than some seconds to view a specific page, a user will normally leave the site. However, it’s a fact that the database will grow while the application will become more popular but it’s possible to save a lot of time if using right database, and structure. In this thesis MongoDB and MySQL will be compared with focus on time consumption. SQL (Structured Query Language) is the language which most databases use. This kind of database stores data in structured tables and noting can be added to them if the type of data is incorrect. SQL also support relations between tables. MySQL is a very popular relational database management system (RDBMS) which for example websites frequently makes use of. NoSQL is a new type of databases where the data is stored in collections without any kind of structure, unlike the well known SQL databases where the data is stored in structured tables. Because of the non-structure, these types of databases are designed to be fast and scalable over multiple machines. Mongodb is a such kind of NoSql-database. Tests has been done both on inserting and processing when handling up to 4 millions entities, MongoDB performs better in almost every test. Results shows that the processing time is shorter using MongoDb in the cases that this thesis is covering, and that it’s possible to implement a much fast application when using MongoDb instead of Mysql as database.

Beställaren har efterfrågat för sin hobbyverksamhet en egen webshop där hon kan sälja sina produkter. Beställaren vill ha en användarvänlig sida för att kunna locka så bred publik som möjligt. I framtiden så kan sidan utvecklas till att låta fler säljare ha sina produkter på sidan. Sidan ska ha grundläggande funktioner som en fungerande varukorg, tydlig produktvy samt ett gränssnitt för att administrera produkter. De språk som sidan har utvecklats i är PHP, HTML5, MySQL och CSS. Sidan är en grund med möjlighet till många utvecklingsmöjligheter både funktions och designmässigt. Vårt mål är att göra en fungerande prototyp.

This Master´s thesis deals with the design and implementation of System for remote measuring and data storing in central databese. The system consists of server, which collects data and clients that send data to the server. On the server is installed program Apache in which runs utility script for collecting and evaluating data, written in PHP. Data are stored in MySQL relational database and can be clearly displayed. The client consists of microcontroller ATmega16, which evaluates data from sensors. These data are then transferred via Ethernet using the HTTP protocol through the module XPort.

The work presents the design and real world implementation of an information system serving as an electronic disk with web based access and administration. The task is being solved using the PHP scripting language and MySQL relational database management system. The study examines PHP and SQL databases, states basic facts and explains how they are connected to create one single complex system. Issues of an internet based payment system are being considered too. The proposed system features complete file management capabilities. Separate access rights can be set for individual users. The administrator of the application can display several interesting statistics. Results of the work are being demonstrated on the final web application.

The objective of the thesis is an analysis, design and implementation of a web application which could be used by authors of articles, reviewers and the system administrator for automation of reviewing scientific articles. The reviewing analysis shows requirements required for the application from the viewpoint of users´ roles. The editorial system design deals with the application architecture and a plan of classes. The application is shown together with a description of its implementation.

Koláček, R. Webová aplikace pro tvorbu interaktivních formulářů. Diplomová práce. Brno, 2017. Thesis is focused on analysis, design and implementation of web applica-tion facilitating the assembly of interactive forms. Feature of this application is also administration of filled-in forms and registered users. Thesis also en-compases analysis of comparable simillar applications. Practical part of thesis is final implementation of web appllication using the Nette framework along with SQL database.

Val av databas kan vara ett svårt val då det finns en uppsjö av alternativ. Detta är ett val som alla har framför sig vid skapandet av ett nytt projekt. Denna undersökning av jämförelse med databaser kan underlätta valet av en databas.Genom ett eget experiment av två databashanterare (Mysql och Mongodb), så testades databaserna med läs, skriv och uppdateringsoperationer. En server skapades för att testa databaserna så att en jämförelse kunde ske med latenstider. Med hjälp av tidigare forskning i ämnet så gjordes en jämförelse också.Experimentet visade att Mysql var snabbare och hade lägre latenstider vid läsoperationer, men resultaten från litteraturstudien var oklara eftersom en studie visade på att Mysql var snabbare medan en annan studie visade att Mongodb var snabbare. Resultaten från både experimentet och litteraturstudien visade att vid skriv och uppdateringsoperationer så var Mongodb snabbare med lägre svarstider.Alla resultat i experimentet finns i appendix. / Choosing a database can be a difficult task as there are a plethora of options available. This is a decision that everyone faces when creating a new project. This comparison study of databases can facilitate the choice of a database. Through an own experiment of two database managers (MySQL and MongoDB), the databases were tested with read, write, and update operations. A server was created to test the databases so that a comparison could be made with latency times. Using previous research on the subject, a comparison is also made. The experiment showed that MySQL was faster and had lower latency times for read operations, but the results from the literature study were unclear as one study showed that MySQL was faster while another study showed that MongoDB was faster. The results from both the experiment and the literature study showed that for write and update operations, MongoDB was faster with lower response times. All results from the experiment are available in the appendix.
