问题
i'm developing an android application when the user can send a image to my webservice.
Currently on my WebService i get a Base64 string and save it in a table on my database.
My question: Is that a good practice? Because as far as i know the Base64 string is a heavy string. My concern is about the db performance, like when this table gets bigger than 10000...100000 records.
Or should i avoid this behavior?
Eg.: Isntead off store the Base64 string on the database, i could recover the image and save only the URL at my db.
Ps: The database is SqlServer
Thanks for the help guys

To answer your question, I think it's not good practice.
It depends largely upon how you will use these images you will probably load. Then, remember (base64 encoding makes file sizes roughly 33% larger than their original binary representations). The best way would be writing the image and then saving its location in the database.

i think using base64 encoding is very useful for saving URLs in the database. The big size for transmitted image is not good idea and not necessary.
