Can on-device sqlite database of a mobile app be updated without updating the the app at the app store?

I am not an app programmer. I am planning an online e-commerce marketplace app and will be outsourcing the job. I have some programming knowledge and have few questions regarding the design of the app.

I want the app to be fast. so I am willing to store the information on the device using sqlite database, at the cost of space.

After the app is released, there will be new sellers and new product categories. I wish to know if I can update the sqlite database only on the device without actually updating the app at the store?
