So, you might be wondering about the human factors that are also affected in following the business logic instructions. These human factors are regular people you can see running the affairs of the business, and we would highlight them.

Human Factors Involved In A Business

Human Factors Involved In A Business

Some of the human factors you can see involved in a business are:

Programmer: Without a doubt, there has to be a programmer to have the business logic. After all, who else will set up the running of the business logic layer and other entities? The programmer ensures that he follows the business logic and makes sure that the website is working as it should be. Suppose it is an e-commerce website. The programmer puts everything in place and does the necessary test run. The test run will ensure that the business logic layer passes the instructions when users visit the website. Such instruction can be ensuring that shoes instead of dresses come up when a user searches for shoes. Once it looks like the website is malfunctioning, the brand owner will contact the web designer, who will work with the programmer to ensure that everything goes back to how it should be. If the programmer is ever confused about anything, they would go back to the business logic layer and follow all necessary instructions. So, the same way the program has to follow the instructions of the business logic layer is the same way the programmer, a human, also had to follow these instructions. Else, it will defeat the purpose of the business. 

Business Analyst: Imagine the business analyst acting against the instructions on the business logic layer. It would not make sense as these would not balance up, and the analyst will not develop effective strategies to grow the business. The business analyst has to work with whatever is contained in the business logic layer to guide their thought process. The business logic layer contains instructions as desired by the business or brand owner. As a business analyst, the business logic helps you understand how the business runs and operates. So, when you come up with ideas, you can defend them and show how it represents the business. The business logic usually comes in handy for business analysts who did not initially start with the brand. It could be that the business analyst is new. Hence, the business logic will be there as a referencing guide. With time, the business analyst becomes familiar with the business logic and will not need to check it regularly. However, it is always great to have the business logic handy as you could sometimes forget something or need to check and be sure. After all, it is risky to make mistakes in running a business as your competitor can take advantage of it. 

Accountant: It is common knowledge that the financial affair of any organization is important, and you cannot afford to leave it in the hands of a non-professional. Also, the financial affairs of a business can sometimes make or mar it. However, the professional handling this financial affair, the accountant, needs to follow the business logic. Accountants usually work with information/data gotten from a business, and the business logic layer presents such data. When checking the business website, it could probably be that the accountant is checking for all the sales made in a specific month. The business logic layer is what presents these statistics. After all, it is the set of instructions on which the business is running. So, it will also have all of its facts and figures. If an accountant tries to use data asides from what the business logic layer presents, confusion will set in, which will be disastrous. 

Marketer/advertiser: It is common knowledge that the idea of any business is to make sales, and this is where the need for an advertiser or marketer comes to play. They are the ones who have to sell the products and services of the business to its target audience. But, they also need to have a guide on the expected targeted audience. So, they need to what with instructions from the business logic layer. It would not make sense if nursing mothers are the target of a specific business, and the marketers go to boys aged 10 to 13. Of course, these kids do not need the product or service, so they will not purchase it. From the instructions on the business logic layer, a marketer or advertiser will determine the target audience. It also helps them come up with marketing strategies so that the brand can surpass its competitors. 

Graphics Designer: As a business owner, you are aware that you need a brand identity, and it is the job of the graphics designer to help you come up with these identities for your brand. The brand identity could be the brand colors, the logo, and other things that make your brand unique. So, looking through the instructions on the business logic layer can give the graphics designer an idea of what you are expecting to see as your brand identity. It helps to eliminate too much back and forth between you and the graphics designer. The graphic designer gets an in-depth understanding by looking through the business logic layer. It also helps to improve their turnover time and efficiency. 


Below are some of the frequently asked questions about business logic and programming

Why Is It Called Business Logic?

The reason it is called business logic is that it acts as the core of a business operates. Since it serves as the blueprint containing the set of instructions for the business, it is only right to call it business logic. 

What Is The Difference Between Business Logic And Application Logic?

The major difference between business logic and application logic is that application logic is more specific. While business logic centers on the running of the entire business, application logic sends out instructions that focus on that application alone. So, one is general, and the other is specific. 

What Does The Business Logic Layer Do?

The business logic layer contains instructions that base how a business should operate. Without it, there will be no orderliness, and the business may be apart.


It is important to pay attention to business logic as it extends beyond programming and affects almost everything about your business.
