KODAI: A SOFTWARE ARCHITECTURE AND IMPLEMENTATION FOR SEGMENTATION BY RICK REJELEENE A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS OF MASTER OF SCIENCE IN COMPUTER SCIENCE UNIVERSITY OF RHODE ISLAND 2017 MASTER OF SCIENCE THESIS OF RICK REJELEENE APPROVED: Thesis Committee: Major Professor: Joan Peckham Lisa DiPippo Ruby Dholakia Nasser H Zawia DEAN OF GRADUATE COMMITTEE UNIVERSITY OF RHODE ISLAND 2017 ABSTRACT The purpose of this thesis is to design and implement a software architecture for segmen- tation models to improve revenues for a supermarket. This tool supports analysis of su- permarket products and generates results to interpret consumer behavior, to give busi- nesses deeper insights into targeted consumer markets. The software design developed is named as Kodai. Kodai is horizontally reusable and can be adapted across various indus- tries. This software framework allows testing a hypothesis to address the problem of in- creasing revenues in supermarkets. Kodai has several advantages, such as analyzing and visualizing data, and as a result, businesses can make better decisions. -

Several We present STORM, a web framework that allows developers web frameworks (e.g., HAILS [4], JACQUELINE [5], and to build MVC applications with compile-time enforcement of LWEB [6]) already do this. These frameworks, however, have centrally specified data-dependent security policies. STORM two shortcomings that have hindered their adoption. First, ensures security using a Security Typed ORM that refines the they enforce policies at run-time, typically using dynamic (type) abstractions of each layer of the MVC API with logical information flow control (IFC). While dynamic enforcement assertions that describe the data produced and consumed by is better than no enforcement, dynamic IFC imposes a high the underlying operation and the users allowed access to that performance overhead, since the system must be modified to data. To evaluate the security guarantees of STORM, we build a track the provenance of data and restrict where it is allowed formally verified reference implementation using the Labeled to flow. More importantly, certain policy violations are only IO (LIO) IFC framework. We present case studies and end-to- discovered once the system is deployed, at which point they end applications that show how STORM lets developers specify may be difficult or expensive to fix, e.g., on applications diverse policies while centralizing the trusted code to under 1% running on IoT devices [7]. -

MVC Design Pattern Introduction to MVC and compare it with others Gholamhossein Tavasoli @ ZNU Separation of Concerns o All these methods do only one thing “Separation of Concerns” or “Layered Architecture” but in their own way. o All these concepts are pretty old, like idea of MVC was tossed in 1970s. o All these patterns forces a separation of concerns, it means domain model and controller logic are decoupled from user interface (view). As a result maintenance and testing of the application become simpler and easier. MVC Pattern Architecture o MVC stands for Model-View-Controller Explanation of Modules: Model o The Model represents a set of classes that describe the business logic i.e. business model as well as data access operations i.e. data model. o It also defines business rules for data means how the data can be created, sotored, changed and manipulated. Explanation of Modules: View o The View represents the UI components like CSS, jQuery, HTML etc. o It is only responsible for displaying the data that is received from the controller as the result. o This also transforms the model(s) into UI. o Views can be nested Explanation of Modules: Controller o The Controller is responsible to process incoming requests. o It receives input from users via the View, then process the user's data with the help of Model and passing the results back to the View. o Typically, it acts as the coordinator between the View and the Model. o There is One-to-Many relationship between Controller and View, means one controller can handle many views. -
Web App Development Using Python and Django
WEB APP DEVELOPMENT USING PYTHON AND DJANGO A Project Presented to the Faculty of California State Polytechnic University, Pomona In Partial Fulfillment Of the Requirements for the Degree Master of Science In Computer Science By Karan Kohli 2020 SIGNATURE PAGE PROJECT: WEB APP DEVELOPMENT USING PYTHON AND DJANGO AUTHOR: Karan Kohli DATE SUBMITTED: Fall 2020 Department of Computer Science Dr. Lan Yang ____________________________________ Project Committee Chair Computer Science Dr. Yu Sun ____________________________________ Professor Computer Science ii ACKNOWLEDGEMENTS I would first like to thank my project advisor Professor Lan Yang whose valuable guidance helped me whenever I ran into a trouble spot or had a question about my project and coding. Professor Lan Yang consistently allowed this project to be my own work but steered me in the right the direction whenever he thought I needed it. I would also like to thank my committee member: - Professor Yu Sun, for the participation. Without their passionate participation and input, this project could not have been successfully conducted. iii ABSTRACT In today’s world there are so many people who want to be in fit, compete in the bodybuilding competitions, lose weight, and burn fat. However, there isn’t a proper platform where people can get all the needed information such as workout instructions, lifting technique, diet guidance, fitness plans according to each individual’s goals find the cheap dietary supplements and hire trainers/coaches. In this project, I developed a web-app to help people in achieving their fitness goals. The web-app, stay-fit.in, based Django, Python and SQL database technologies, provides users information with regard to fitness, diet, training and fitness related products buying.
