Domain – the online address of the site, the place of its placement on the Internet. From a technical point of view, the domain address is an entry in the database. When a user specifies a domain name in the search bar, the computer understands which site needs to be shown and to which address to send the request.

HTTP – a protocol that gives access to various resources on the Internet. This protocol is the basis of data exchange in the web space. HTTP is a client-server communication protocol, which means that recipients themselves initiate requests to the server.

HTTPS – a protocol more secure than HTTP. It uses SSL keys to encrypt the data so that fraudsters can’t access sensitive information.

Iframe (inline frame) – an HTML tag that denotes a frame. On a website, it appears as a separate window displayed together with other page content in the browser window. This component of the HTML element allows you to embed documents, videos, and interactive media files on the page.

Local environment – a set of configurations of different services focused on your device to launch a web product.

MariaDB – client-server application for storing and retrieving data using SQL queries. This database management system is distributed free of charge and supports all popular operating systems – Windows, Linux, macOS, etc.

MariaDB has a GPL license, while MySQL has a dual license. In addition, MariaDB has much more storage mechanisms than MySQL. Compared to another popular database management system – MongoDB, MariaDB (same as MySQL) uses rows and tables while MongoDB presents documents in the form of JSON collections.

Metrics – a set of measurements of the performance of software that allows you to critically evaluate its properties or specifications. Software metrics include the number of lines of code, loading speed, the number of errors per 1000 lines of code, the number of classes and interfaces, and many others.

MongoDB – a document-oriented database management system that doesn’t use tables, schemas, SQL queries, foreign keys, and many other things inherent in object-relational databases. It is considered one of the classic examples of NoSQL systems. MongoDB is written in C++.

MySQL – a database management system (DBMS) distributed as free software (users have the right to unlimited installation, launch, and free use). MySQL manages databases with interconnected tables and can help you improve your site’s performance. It works on the client-server principle: the user’s computer (client) sends a request, the database server processes it and provides a response.

Feel free to use the assessment tool on our website to check your site’s performance.

Performance – the sum of measurements and user feelings related to the loading and operation of the application. The level of performance of a website is usually manifested in ensuring fast loading of content, responsiveness to user interaction, and ease of dealings with content.

QA also includes quality control of all processes of the organization, even those not directly related to the product.

Search – an important element that allows users to navigate and find specific elements on request. There are three types of search queries: 

  • Navigational (a user knows what to find but doesn’t know where) 
  • Informational (a user is looking for specific information)
  • Transactional (a user is searching for how to make a purchase).

SEO (Search Engine Optimization) – a set of methods that allow adjusting the characteristics of a website to the requirements of a search engine. SEO is crucial for the site’s position on the search result page. It leads to growth in traffic and strengthens the competitiveness of the company.

Server – a computer that processes requests from other client computers within a network protocol. It helps other devices solve certain tasks of executing program codes, storing information, servicing users and databases.

Staging site – a platform containing an exact copy of the hardware and software of the website. It is used for testing the product and debugging before uploading the final version to a working hosting. This phase follows the development stage.

Version control – a set of software tools that give developers control over changes in the source code of computer programs, documents, large websites, or other sets of information over time. Since development environments tend to constantly change, version control helps to update site performance indicators. The most popular version control system is Git, but there are plenty of them.
