About ServiceNow development topics

[smshaik22]

Hi everyone,

This is Moulali. I started to learn ServiceNow in the last 3 months. I completed the administration part, and then I started the development part with client scripts and server-side scripts, feeling some difficulty understanding the server-side scripts, especially the Glideajax concept and the business rules topic script codes.

Looking for help from the community end who can provide a clear explanation on the above ask.

Appreciate your time helping me understand these topics.

Thanks,
-Moulali

Hi @smshaik22 

I’m a ServiceNow trainer and happy to guide you on this. Since you’re new to development, and I assume you’re also new to ServiceNow, here are some courses you can follow:

• CSA (Certified System Administrator) is the first and foremost certification. If you’ve already completed CSA, the next step is CAD (Certified Application Developer). There are journey visuals available in ServiceNow’s community that can help you prepare for CAD.

Learning is always good, but it’s important to know how and where to start. While JavaScript is required in the ServiceNow world, with the platform’s shift toward low-code/no-code, you don’t need deep JavaScript expertise to begin.

You can follow Chuck Tomasi’s videos to learn Javascript:

You can also refer to these courses:

• Scripting in ServiceNow (Developer Site)

• ServiceNow Application Developer Learning Plan

These links are great starting points.

Hi @smshaik22 ,

I will try to explain in a very simple language:-

Business Rule - if you want to get the data from any table or want to manipulate teh data - set, delete etc then you require Server side scripting. Where you will write your server side scripting so that it can be saved and can run further - Business Rules. Here you will write the code to manipulate data (as per busienss requirement). There will be different type sof BR- like- Before, After etc so basically when you want to manipulate data (CRUD - Create, Read, Update and delete) before it is saving in table or after it is saved in table, you will select BR accordingly.

Glide Ajax:- So you learnt Client script which will work on front end (form, catalof etc) and you learnt Service side scripting which will help in gettign data from backend (table). Now if you are on Front end and want to data from backend - how you will do it? Glide ajax is for that purpose. It will help in the communciation of client script and server side scripts.

I tried to explain in a layman language, hope it is clear. If not, you are welcome to ping me one to one. 

If my answer helped you, please  mark it- solution accepted. 

Regards,

Nikhil Bajaj
