In this article we will be exploring Unit of work and Repository pattern with EF Core and .Net 5. You can watch the full video on Youtube: Please find the source code on GitHub: https://github.com/mohamadlawand087/v33-repo-uow So what we will cover today: As always you will find the source code in the description down below. Please like, share and subscribe if you like the video. It will really help the channel What is a Repository Pattern The repository pattern is talked about a lot, especially in the API-and-microservice-heavy world that .net core shines in. The repository pattern is a strategy for abstracting data access layer. So what is a data layer? it is made up of the code in the application that is responsible of storing and retrieving the data. Adding, removing, updating, and selecting items from this collection is done through a series of straightforward methods, without the need to deal with database concerns like connections, commands, cursors, or readers. Using this pattern can help achieve loose coupling and can keep domain objects persistence ignorant. Why use Repository Pattern There are many reasons why we want to use code absatractions What is Unit of Work (UoW) If the Repository pattern is our abstraction over the idea of persistent storage, the Unit of Work (UoW) pattern is our abstraction over the idea of atomic operations. It will allow us to finally and fully decouple our service layer from the data layer. The unit of work pattern now manages the database states. Once all updates of the entities in a scope are completed, the tracked changes are played onto the database in...
10 Ways to Reduce Mobile App Development Costs Any business pursues quite an obvious goal — to reduce mobile app development costs. The limited budget is one of the reasons why some customers refuse to develop a project, losing new business opportunities. However, since the product development process consists of several stages, you will be able to significantly reduce the time and money costs if you understand the features of each particular stage. In this article, we will talk about ways to reduce mobile app development costs without losing the coming product’s quality. 1. Make Detailed Requirements Specification Software engineers cannot read minds. Consequently, the more blurry the customer explains their requirements the more unpredictable the result may turn out in the end. Describe your project in detail: Based on a detailed project description, developers will evaluate implementation costs and development time much easier and answer customers’ other important questions. Want to start a project? Our team is ready to implement your ideas. Contact us now to discuss your roadmap! 2. Start with One Platform and MVP MVP (minimum viable product) is the product working prototype, using which it is possible to test market demand before a full-scale launch. The main goal of MVP is to test the software idea spending minimal cost. We can name Foursquare, Uber, and Snapchat among the well-known apps which started as MVP. It is better to spend a certain amount of money and understand that a specific idea or feature is not in demand than to spend ten times more money and then come to the same conclusions. The first version should have...
Welcome to Cyber Security Today. This is the Week in Review edition for the seven days ending Friday May 14th. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. In a few minutes guest commentator Dinah Davis, vice-president of research and development at managed service provider Arctic Wolf, will be with me to discuss what we think were notable events. But first some of the headlines from the past week: Outrage and worry erupted after one of the biggest gasoline pipelines in the U.S. was hit by ransomware. Colonial Pipeline decided out of an abundance of caution to shut its service, which provides fuel to almost half of the East Coast. Operations were restarted on Wednesday. Also on Wednesday President Biden signed an executive order to toughen cybersecurity in the federal sector. It removes barriers to cyber threat information sharing between American agencies and the private sector. It also orders federal departments to implement mandates multifactor authentication and use encryption to protect data. Ryerson University’s cybersecurity policy exchange called on the Canadian government to find ways of stopping misinformation, disinformation and fake news from being spread on private messaging services. These are services like Facebook Messenger, WhatsApp and Telegram. A report says many of these platforms are being used to spread hate, unwanted sexual comments and materials that incite violence. A student’s eagerness for free software led to a ransomware attack on a European biomolecular research institute. The student worked as an intern at the institute. They hunted the internet for a free version of a data visualization tool. What they got was an infected application that stole the...
I always tell people that finding a good web developer is like finding a good mechanic. Like with mechanics, you can get ripped off, and/or the work might not be up to par causing your website to need to be repaired or redone. Unfortunately, with having been a UX/UI designer and web developer for decades, I’ve seen it all. I have seen code that looks like it was written by someone who is five years old, websites that were incredibly overpriced only to have to be redone, and I have seen clients lose access to their website and not have true ownership of it. Your website is incredibly important. Not only is it something you will likely spend a good amount of money on, it is something that is most likely vital to your company’s revenue capabilities as well as an information hub for existing customers. Also, remember that your website is a reflection on you and your company. It’s often times a first impression. While it would be easiest to just hire Dashal, here are must-ask questions for a web developer or agency you are having design and develop your website. CMS (Content Management System) What content management system are they using? This is very important as you need the ability to update your own content. You never want to be in a position where you have to rely on other people. Most sites now use WordPress. While there are others, there is really no reason to use them as there isn’t anything that can’t be done in WordPress and it is so popular that should you need...
Introduction It happened few years back. After working on SAS for more than 5 years, I decided to move out of my comfort zone. Being a data scientist, my hunt for other useful tools was ON! Fortunately, it didn’t take me long to decide, Python was my appetizer. I always had a inclination towards coding. This was the time to do what I really loved. Code. Turned out, coding was so easy! I learned basics of Python within a week. And, since then, I’ve not only explored this language to the depth, but also have helped many other to learn this language. Python was originally a general purpose language. But, over the years, with strong community support, this language got dedicated library for data analysis and predictive modeling. Due to lack of resource on python for data science, I decided to create this tutorial to help many others to learn python faster. In this tutorial, we will take bite sized information about how to use Python for Data Analysis, chew it till we are comfortable and practice it at our own end. Table of Contents Basics of Python for Data Analysis Why learn Python for data analysis? Python 2.7 v/s 3.4 How to install Python?
