What is the good mechanism to store information among SQLite database and Shared Preferences?
Why use shared preferences? Why use sqlite? I tried to find the difference between them, and which is the better mechanism for data storing, but I am unable to find the appropriate answer on Google. Please help me with example and explanations.
It really depends on the data you want to store.
SQLite
Large amounts of same structured data should be stored in a SQLite database as databases are designed for this kind of data. As the data is structured and managed by the database, it can be queried to get a sub set of the data which matches certain criteria using a query language like SQL. This makes it possible to search in the data. Of course managing and searching large sets of data influences the performance so reading data from a database can be slower than reading data from SharedPreferences.
SharedPreferences
SharedPreferences is a key/value store where you can save a data under certain key. To read the data from the store you have to know the key of the data. This makes reading the data very easy. But as easy as it is to store a small amount of data as difficult it is to store and read large structured data as you need to define key for every single data, furthermore you cannot really search within the data except you have a certain concept for naming the keys.
