As the main requirements to the online store were high performance, modular structure and versatility it was decided to use a modern PHP framework Yii framework.
Percona Server DBMS was chosen as the main data storage, because of its high capacity of data access. As an auxiliary “fast” database for storing users’ feedback we choose document-oriented DBMS - MongoDB. For implementing a quick search for products and categories we chose Sphink Search Server, which allows receiving data for search queries based on formed search indexes in a fraction of a second.
We were choosing a technology for the development with an emphasis on the reliability of performance of the system.
