    Security & Future, Vol. 6 (2022), Issue 1, pg(s) 32-34

    The use of ID-1 cards is in an extremely large increase nowadays starting from identity cards, bank cards, driving licenses, membership cards, etc. In some of the uses, the security of the card and the data that the card holds are very important. Some of the security elements are defined in the production of the card and some during the personalization of the data on the card. Laser card engraving is a high-security feature that is applied during the process of personalizing the data on the card. In this article, we will present h ow to implement the digital signature in the data personalization using laser engraving and QR barcodes to minimize the costs of cards and to ensure the data on cards are not modified.


    SQL vs NoSQL databases from developer point of view

    Industry 4.0, Vol. 7 (2022), Issue 3, pg(s) 95-97

    Application developers mostly must choose between two main categories of the database: SQL (Structured Query Language) and NoSQL (Not Only SQL) to build their solutions. SQL databases, also known as relational databases, have been in use for a very long time and despite their age, SQL databases remain extremely popular with developers. Six of the top 10 results on DB-Engines’ list of most popular DBMS are relational DBs (September 2021). In the meantime, NoSQL databases or non-relational databases, have gained popularity year after year. One of the most widely used NoSQL databases is MongoDB, ranked 5th on DB-Engines’ list. In this article, we will explore what are the differences between SQL and NoSQL, and which database to use for application development.
