无法使用数据库时存储数据的最佳方法是什么？

Question

I am designing a e-Diary application in which the user can store textual data EVERY DAY .

I thought of using a database but now I am looking for other alternatives , thought of encrypted files , but what if they get deleted ?

Could someone provide me ways of doing this.

BTW, I am using Java.(If this is important).

EDIT: Currently I am using files for acheiving this, for login I am using a file in which the username, password are stored in the format username:password , This is not a good approach, so I am looking for some secure approaches.

Answer 1

Serialize your Data and store it using flatfiles.

But why dont you want to use SQlite?

Serializing and storing to the disk is a database aswell.

If you want to serialize it there are a few tutorials and code examples around.

check How to serialize an object into a string

for example.

If you want to use a proper database (which is recommend!) you may check different databases and examples at Java and SQLite
