Why Use MongoDB?

Elitech Systems — Fri, 06 Nov 2020 16:27:13 +0000

MongoDB is a database system. It has become extremely popular over the past few years.

In this article, we'll take a look at what MongoDB is, when to use it, and when to avoid it.

What is MongoDB?

MongoDB is an object-oriented, dynamic, stable, scalable, SQL-free database system. The objects are stored in JSON format in separate documents. Instead of storing the data as tables with values, we use a hierarchy and a JSON object system to create a more adaptive system.

The advantage of MongoDB is to implement a high-performance system with perfect scalability. The system is extremely easy to install, it works under all operating systems and there are libraries to handle it in all languages.

MongoDB vs SQL

The vast majority of databases run on SQL. Be it SQLite, Postgres or even Mysql, the base language is common. MongoDB belongs to the family of NoSQL languages. The code and functionality are therefore fundamentally different.

Where SQL will use a system of tables and complex relations, MongoDB works quite simply. We create a document with tree data. It is then possible to link these documents with links by _id

MongoDB's big advantage over SQL is its ability to handle complex data systems. We can have lists, encapsulated objects without having to worry.

This operation greatly facilitates the development of applications that handle a lot of data. With a little practice, it is possible to create extremely well-organized document templates, which saves time.

The advantages of MongoDB

No system is perfect, so let's take a look at the advantages of MongoDB to help you make a choice:

Document orientation
Excellent performance
Simple to replicate
Very good scalability
A totally dynamic system
Very good flexibility
Heterogeneous data
A management system in JSON and BSON (binary JSON)
A search and modification system as good as SQL

Excellent performance compared to the cloud. AWS, Google Cloud and Azure offer solutions to implement MongoDB very easily.

The disadvantages of MongoDB

MongoDB has a few drawbacks. It is important to take them into account when making your decision:

Does not work with a table system, so you need to learn how to create document schemas
Complex transactions
No direct system to create links between documents

In which situation to choose MongoDB

Here is a list of the types of applications that work very well with MongoDB:

An e-commerce site
Blogs and content management
Real-time management applications
Social networks

In conclusion

MongoDB is a very powerful database system. It doesn't work with SQL, so you'll have to learn a new language. The data is stored as JSON documents, so it is possible to create complex trees.

Payment Gateways - Selection criteria and configuration prerequisites

Elitech Systems — Wed, 07 Oct 2020 05:25:29 +0000

Payment gateways connect your site to your bank account. This article tells you more. Use our tips to make the right choice. Find out about the conditions required by the majority of providers to ensure the security of personal data.

Payment gateways are essential in the world of e-commerce. Indeed, to be able to receive money through your customers, you must have a gateway. In short, a payment gateway ensures the connection between your website and your banking institution. In some cases, this provides the connection between your site and your online wallet. The purpose of this article is to see how payment gateways work. We will also talk about the requirements imposed by the owners of the gateways and finally, we will discuss the most popular on the market.

I - How payment gateways work

Roughly speaking, a gateway is a web application or recovered software that allows you to communicate with your bank through your website. Indeed, a direct connection between your website and your bank account is currently not possible. You must between e-commerce owners call on the supplier being able to give you codes to install on your site to accept payments by credit card.

How it works?

Generally speaking, you should:

Get in touch with suppliers offering this type of service. There are several depending on your locality, type of website, or budget.
Reassure you that they offer a possibility to connect with your platform. However, it is not possible to easily connect all gateways to all web solutions. To this end, you must see a developer or make sure that the supplier supports your solution.
Connect your website with their app. Alternatively, if you have access to their programming interface, you can use it.
Establish a connection between your bank account and the software. Alternatively, you need to make sure you have a way to get hold of your money.

Some basic rules

The basic principle in setting up a payment method on a website is security. Several providers have established a list of conditions that must be met in order to use their service. Below are some rules to follow:

Have an SSL / TLS certificate (see https on the browser)

SSL certificates are intended to encrypt communication between your server and your visitor's browser. In theory, if by chance a malicious person came into possession of the data sent by a visitor to your site, he would only see encrypted information. In practice, this is not always the case; because SSLs have several versions which provide security at different levels.

Have a privacy policy page

Considering the fact that you collect personal information from your customers, it only makes sense to educate them on how you handle their data. The privacy policy page informs customers about the measures you have in place to ensure the confidentiality of their data.

Cookie Policy and Other Terms.

If your website uses tools such as cookies, or software to collect data, you must specify them. Typically required pages are:

Terms and conditions
Return conditions
The cookie policy.

Other measures to ensure the security of your eCommerce

In addition to following your supplier's recommendations, you must put in place a security process to avoid any future problems. Some of these measures are:

Protect your forms against spam

Unwanted emails or spam weaken your email server and are sometimes the source of several other security problems. To be able to effectively fight spam, you can install a Captcha. You can also read our article on "How to protect your website against spam with Google Captcha V3 [PHP]"for how to install Captcha on your website.

Force your users to use more secure passwords

If the passwords used by your customers are not secure enough, it could be a loophole. Some tips that you can plan when setting up your payment process or creating an account can be:

Require a certain length of character. For example a minimum of 8 characters.
Prompt user to include special characters
Request a mix of character types.

A trick may be to autosuggest a password to the user.

Filter the information sent through your forms.

The types of information submitted through online forms can never be trusted. Indeed, if you do not filter your forms, several people can use them to destroy your site. Some types of vulnerabilities you might have are:

Sending malicious code via your forms
Injecting your database
Theft of your data

II - How to choose payment gateways for your website?

Before embarking on finding payment gateways for your website, you should ask yourself the following questions:

Is it easy to integrate with your web solution?
Is there a way to sync the software with your bank account?
What are the fees per transaction?
What are the security measures implemented by the company?
Will I be able to customize the payment page?

Can it be easily integrated with your web solution?

There are thousands of payment gateway providers across the world. However, not all suppliers have implemented the codes to easily integrate their solution into all types of applications. You could still refer to their documentation to see how to do it "yourself". In most cases, the most popular solutions give you access to their development interface to be able to make the connections. That said, if you are keen on using a solution, you can work with a developer.

Is there a way to sync the software with your bank account?

A good number of providers easily connect with bank accounts. However, you must take the time to educate yourself to avoid any surprises.

What are the fees per transaction?

The fees associated with integration or transactions may vary from vendor to vendor. As an example, Paypal fees are from 2.9% + $ 0.30 per transaction in Canada. You should therefore take the time to compare before you decide. You should keep in mind that cost is not the only criterion to consider.

What are the security measures implemented by the company?

The security of your data and that of your customers is very important in online commerce. For this purpose, you must take the time to find out about the provider you want to use. Some elements to take into account could be:

Reviews from other customers
The privacy and security policy in place
Their approach to protecting data

Will I be able to customize the payment page?

Some providers only offer the possibility of using the ifs reams to integrate the payment gateway on the websites. And as a result, it affects the performance of websites and reduces the number of online orders. Taking the time to reassure yourself that you have the ability to customize could be helpful. In most cases, if you have access to the API, you can control the visual of your payment page.

III - Some examples of payment gateway providers

There are thousands of solutions for websites. Among which we can cite:

Paypal - Very popular gateway present in almost all countries of the world. It has the particularity of having several currencies depending on your country and to protect the consumer in the event of a dispute. One limitation of PayPal for certain countries is that you must have a bank account to be able to sync your account. For this, PayPal is not very suitable for countries that are still developing.
Stripe - Fairly easy to integrate; but not available in several countries. For the moment stripe is only present in 34 countries; contrary to PayPal which is present in more than 200 countries and in more than 25 currencies
We Cash Up - A better alternative for developing countries. If you don't have a bank account and are in a less industrialized country with people who don't use banks as a method of financial transaction, We Cash Up can help.

In the tech world, questions that start with "How much does it cost?" Often do not have a single answer. So, if you are wondering how much it costs to create a website, we can only answer that it depends on a lot of things.

What type of website do you want to build?
What profiles do you need to create it?
What quality do you demand?
When do you need it?

These are all factors that have a major impact on the cost of creating a website. In this article, we're going to go over a few of them and give you some price estimates to give you an idea of what a website costs. Read on!

The price of a website

You may have seen prices of all kinds. Some people claim to make you a website for 100 dollars, but how safe is that? There is a tool to find out how much a website costs, called " How much does my website cost ".

Nevertheless, it is a very simple tool that can only give you a first approximation. Indeed, it does not take into account other very important aspects when calculating a web development budget.

Another possibility is to go to our website to request a personalized budget presenting the characteristics of your project, whether it is an application or a website.

How much does it cost to create a website depending on the type of site?

Let's start from the beginning. Not all websites are the same. Depending on your business or what activity you do with it, you will need more features. When defining the type of website we find several options.

Blog or website with WordPress

This is usually the cheapest option for making a website. In this case, it is enough to prepare the WordPress CMS in the desired domain, install the desired template, adjust its design, and include the content.

Depending on the quality you are looking for, only the development of a custom WordPress can bring in between $ 1,500 and $ 4,500. If you also want to add the unique design to your website instead of using a predefined template, the cost could be over $ 5,000.

E-commerce

In the event that one wants to create electronic commerce, the price of creating a website increases considerably. An online store is more difficult to manage and create. This type of website will have many more unique pages and take more work to create.

There are several technologies to create an online store: Woocommerce, Magento or Prestashop are the best known and used by companies. The development of e-commerce with these technologies is practically the same, perhaps with Prestashop a little cheaper.

However, in all cases, you will need a budget of between $ 2,000 and $ 8,500 for e-commerce.

Custom web

A very simple custom website design could be done for around $ 2,500, but without a good design or marketing strategy, you won't get anywhere. This type of personalized web page concerns companies that do not correspond to the descriptions above, companies that need their own management like Yeeply itself or a website like BlaBlacar or MilAnuncios.

Of course, there are companies that invest and reinvest in the development and maintenance of their website. They even end up spending thousands and thousands of dollars. But in this case, we are talking about the first version of a website tailored to your needs.

The cost could be around $ 2,500 if you don't need great quality or design. Alternatively, we could talk about an investment of up to $ 16,000 if you want to initiate a custom design and digital marketing strategy for your website.

Services you might need

Just like we've seen you before, development isn't everything. When you are going to outsource the creation of your website, you must take into account the services that you will need.

Web development

This is the basic service you will need. But without a web design, there is no point in having good web development or creating a website.

Web design

Web design is intimately linked to web development, they almost go hand in hand. You need a well thought out design with the help of the developer. Whether you provide it yourself or need to hire one. You have to know this before web development begins because without it we cannot begin.

MVP

In this case, it is about creating a Minimum Viable Product (MVP) . That is, the basic website that we will need to start a project. This type of web development is expressly indicated for businesses that are about to start and need a first version of their website.

Advice

In addition to the development of web or mobile applications, Yeeply offers the possibility of calling on a consultant for projects. This case is specially designed for companies that are starting in the digital or mobile environment and do not know exactly how to deal with the project.

We have experts in digital environments who can advise you on how to create a suitable website or mobile application.

Marketing

And finally, digital marketing. In the case of websites, the sooner you start working with your marketing team and preparing your web code to analyze visits, as well as site promotion, the better.

Often the marketing strategy begins before even launching the website to the public. In fact, a small phase of preparation or set-up is necessary. Keep this in mind when starting your website project.

The quality of your website

Sometimes it's not about wanting low quality, but rather that the state of your project is forcing you to start with low quality. For example, if you want to make an MVP, it makes sense to invest in a lower quality first version of your website.

If your business is growing and you want to take a qualitative leap, you will definitely want to invest in a higher quality than you have had so far. In many cases, this quality translates into good design, good development, but also a completely tailor-made project. Although they also require larger budgets.
