What is nosql?

From the updating of information to the unveiling of new technology services, NoSQL databases came and replaced relational databases or SQL. The main reason for this move was that SQL did not have the necessary capability and speed to store and process the information of large companies, and this was the beginning of the story of NoSQL!

Before starting the article, if you are still unfamiliar with the concept of database and database, be sure to read the article “What is a database?” read the article ” This article fully discusses the concept of database and storing information in the database.

Now, what is NoSQL? Where did it come from? What are its uses and benefits, and the differences with SQL are the questions we will answer in this article, so be sure to stay with us until the end of this article.

How To Secure Databases?

The fact is that information security is a complex process of computer software and hardware. Organizations have to use security equipment and tools based on strict and calculated policies to properly implement communication infrastructure and databases not to challenge sensitive organizational data.

Information security and the security of computer networks are among the responsibilities that require the recruitment of skilled personnel. Addressing the issue of information security and computer network security requires the attention of all users, regardless of job status and age, to the position of information security and computer network security.

Existence of security weakness in computer and information networks, lack of proper training and justification of all users regardless of their job responsibility for the position and importance of information security, lack of necessary instructions to prevent security defects, lack of clear and codified policies And promptly, security issues will lead to issues that harm an organization and the people associated with that organization.

Achieving the three key principles of the security world

In the world of triple security, the principles of confidentiality, integrity, and accessibility are the keys to solving all security problems. Properly covered, it will withstand a lot of adverse conditions. The definition of each of these three principles is as follows.

Confidentiality

Confidentiality means that unauthorized persons do not have access to information. For example, to buy credit cards online, you need to send the credit card number from the buyer to the seller and then to the transaction processing center. In this case, the card number and other information about the buyer and his credit card should not give to unauthorized persons, and this information should be kept confidential.

In this case, to keep the information confidential, the card number is encrypted and remains encrypted during the transferor where it may be stored (in databases, system event logs, backup, print receipts, etc.). Access to information and systems is also restricted. If the unauthorized person obtains the card number in any way, a breach of confidentiality has occurred.

Violations of confidentiality can take many forms. For example, if someone reads confidential information displayed on your computer screen from your shoulder. Or selling or stealing a laptop containing sensitive information. Or giving confidential information over the phone is a violation of all confidentiality.

Integrity

Integration means preventing an unauthorized change of data and detecting a change in the event of unauthorized manipulation of information. Integrity is violated when information is unauthorized altered during transmission and use or storage, or destruction. In addition to the confidentiality of information, information security systems typically ensure its integrity.

Availability

The information must be available when required by authorized persons. This means ensuring that the information storage and processing systems and communication channels used to access information are properly operated and prevented from malfunctioning. High-access systems remain available at all times, even due to power outages, hardware failures, and system upgrades.

One of the ways to make information and information system inaccessible is to make many requests through services from the information system, in which case, because the system does not have the ability and capacity for such a large volume of services, it is completely or partially unable to provide services.

What is database security?

Database security refers to using various information security control methods to protect databases (including data, applications or stored functions, database systems, database servers) against confidentiality, comprehensiveness, and accessibility agreements. Database. This includes various types of control methods, such as technical, procedural, and physical.

Database security is a specialized subject in computer security, information security, and risk management. For example, security risks associated with database systems include:

Malware problems can cause unauthorized access, disclosure of personal or proprietary information, deletion or damage to data or applications, interruption or denial of authorized access to the database, attack on other systems, and unexpected failure of database services.

Design flaws or programming bugs in databases and related programs and systems that cause various security vulnerabilities, such as data loss, data corruption, reduced performance, and so on.

Unauthorized or unwanted activity or misuse by authorized database users, database administrators, system/network administrators, or by unauthorized users and hackers (for example, improper access to sensitive data, metadata or functions within the database, or improper changes to Database applications, structures or security settings);

Overload, performance constraints, and capacity issues and, consequently, authorized users’ inability to use the database.

Physical damage to the database server may occur due to server room fires, floods, overheating, lightning, etc.

Data corruption or loss due to invalid data entry or command, errors in database or system management processes, intentional sabotage or criminal damage, etc.

The most important layers and methods of controlling information security concerning databases should be access control, database auditing, authentication, encryption, data integrity, backup, and application security.

A brief look at the history of NoSQL

 

A NoSQL (non-relational) database stands for Not Only SQL or Not SQL. You might also be interested that some businesses in the 1960s were using non-relational databases to store their information. But in 1998, a person named “Carlo Strozzi” introduced a broader concept of this database.

From 2000 to 2008, some companies used non-relational databases in a limited way, but 2009 was the time of SQL’s underperformance and the full emergence of NoSQL.

The emergence of this database made this concept work like a miracle for large companies such as Google, Amazon, Facebook, etc., who deal with a huge amount of information.

NoSQL or SQL is the issue!

To better understand non-relational databases, it is not bad to first go to SQL to get familiar with its structure and then tell you the differences between these databases.

SQL stands for Structured Query Language, a fully standardized programming language for organizing structured data. In today’s world, millions of data are generated every minute, and we are faced with raw data that has no story to tell. SQL is used to extract and analyze this data.

SQL database consists of tables and fixed columns; each column is designed to store a specific type of information. This framework and SQL tables are its main limitation and problem for storing unstructured data.

What are the differences between SQL and MySQL?

SQL and MYSQL are two widely used terms in enterprise data management; although MySQL uses the SQL language to search the database, they have many differences, which may seem a bit confusing for some newbies.

As we said above, SQL is a standard programming language for setting up a relational database management system, and MySQL is a free open-source relational software that stores and retrieves data easily.

Note: The most important reason for MySQL’s popularity is its availability and ease of use.

In the following, we have listed some of the differences between SQL and MySQL for you:

What are the advantages of using a NoSQL database?

 

Non-relational databases have several advantages over relational databases, the most important of which is the management of large amounts of information. Learn more about the benefits of this database.

Conclusion

Although we can consider the emergence of the non-reonal databases as an important and pleasant event in computer science and software development, it is still not the right choice for data classification! The best solution to choose is to pay attention to your upcoming plans and needs.

We tried to make your work easier by examining the differences and presenting the advantages of non-relational databases. Still, in general, if your data is highly related, SQL is the best option for you if you are faced with a large amount of information.
