I have two types of incomes business and professional. which section should i use 44ad or 44ada

I have two types of income, one from my small business which is an online publishing business for which i am a sole propriotor. And other is professional i.e. i provide online technical training/consultancy. The income for the professional one is not related to my business and i receive it in my personal account.
In this scenario, which section should i use to file return. 44AD or 44ADA or both.
Please help
