Explain, with a minimum of two examples, the differences between relational databases and NoSQL databases in terms of scalability and handling database transactions.


A Adrian Boyles

With regard to scalability, the relational database model is only scalable in the readability aspect. In order to handle an increased load, this can be achieved by through additional servers to the cluster. The downside to this is that it can result in performance or bandwidth bottlenecks in the event that the database tries to scale up a single server. An example of this would be a MySQL database which must manage customer information for a given business with a relatively low volume of data traffic, with just enough scalability in the event that the business grows. In contrast, the NoSQL database are scalable on both levels. Due to the inherent distribution of the data across multiple servers, the scalability improves, which then allows for handling large quantities of data and bandwidth. A better use case for NoSQL is having to manage an application or website with potentially millions of users across the world. The decentralized data will be able to handle the high volume of traffic.

When it comes to Database transactions, the relational model has built-in support for complex transactions. Additionally, it is ACID compliant, which basically has one point of failover, is consistent across the network, and the transactions do not interfere with each other. In contrast, the NoSQL database does not have the same support for complex transactions and can only support very basic functions depending on the kind of NoSQL structure that is being utilized.

B Trevor Stoutt

While relational an NoSQL databases both manage and store vast amounts of data, there are some differences in how the two databases accomplish this task.

The first is scalability, relational databases such as SQL or Oracle store data vertically, which means that the databases runs off of a single server and can handle more data loads by adding for resources to the server like extra RAM or CPU. In contrast, NoSQL databases store information horizontally, so when it comes to scaling that is done throughout multiple servers by which adds to the workload that the database can process (n.d.,2022).

When it comes to handling and processing transactions relational databases are programmed to use the ACID method, this method ensures that each transaction is consistent and that all transactions are completed. An example of this would be when a customer pays a bill and then their bill is updated to reflect their current balance instead of the balance prior to the transaction. Likewise, in a NoSQL databases transactions are designed to have eventual consistency, meaning that it may take the system extra time or multiple transactions compared to the single Atomic transaction that takes place within a relational database (n.d.,2022).

C Joshua Victor Kirabo Kisaku


Relational databases like MySQL utilize a fixed schema to organize data. This can make it hard to scale data horizontally (by adding more nodes to the database cluster). NoSQL databases, like MongoDB, offer a more adaptable schema and make horizontal scaling simpler.

Handling database transactions:

Relational databases, like Oracle, use ACID (Atomicity, Consistency, Isolation, Durability) transactions, which guarantee data integrity by ensuring that a transaction is performed entirely or not at all. NoSQL databases, like Cassandra, may not offer the same level of transactional guarantees and instead place a higher priority on partition tolerance and availability.

Is it important to study communication? Why or why not?


A Aminata Mansaray

Yes, it is essential to study communication. Communication is a fundamental aspect of human interaction and plays a crucial role in our personal and professional lives. Practical communication skills are essential for building and maintaining relationships, resolving conflicts, making informed decisions, and conveying thoughts and ideas effectively. Good communication can also improve one’s confidence and self-esteem and help individuals express themselves clearly and concisely. In a rapidly changing world, where information and ideas are shared globally, effective communication is becoming increasingly important, especially in the workplace (Izzulhaq & Simanjuntak, 2022). By studying communication, individuals can better understand the process of communication and the many factors that impact it, such as culture, language, and social dynamics. With this knowledge, they can hone their communication skills and better navigate various interpersonal and professional situations.

B Justin Quick

  Communication is essential in every day-to-day interaction with other people and the class book outlines five communication principles, (1) understanding how you communicate with yourself and others, (2) how you use and interpret verbal messages, (3) how you use and interpret nonverbal messages, (4) listening and resound to other people, and (5) adapt messages when needed to other people. Communication is not just a learn-once-and-done skill but it can be improved upon by learning techniques to assist in employment, relationships, and even your health. Communication is defined as acting on information someone has said or did and then having a response to that. It is quite important to study communication because it has so many layers, techniques, and interpretations as it continues to evolve into the present time. There are three models to look at when communicating, an action that is linear from source to receiver, interaction when the receiver responds to the message with action/reaction, and transaction with simultaneously interacting of sharing information back and forth (Beebe et al., 2022).

Ariel Fuller

Proverbs 15:1 explains on how communication is important in our daily lives, and why it is so powerful. This is basically saying that when a lot of times people of ask us to do something a lot of time we react in a negative because we don’t want to do it or we feel like why we should do it. when we do this, it shows a negative view on us, and God wants all of us people to act accordingly to his well and to behave properly.
