The data to be stored consists of fields.The Paper database is a great choice when: Querying data from the database is a problem, especially categorical data.
Huge amount of information cannot be stored within the paper database. It is relatively faster than other databases. Since it only takes column data, Paper databases consume less memory as compared to other databases. 
It allows users to use Java/Kotlin classes without any annotations, factory methods, or required class extensions.Īdding or removing fields from data classes is also no longer a chore because all data structure changes are handled automatically. The goal of PaperDB is to provide an easy-to-use yet fast object storage solution for Android. PaperDB is a NoSQL-like database for Java/Kotlin objects on Android that supports automatic schema migration. This tutorial aims to explain what Paper database is, where to use it, the advantages and disadvantages of Paper DB, and how to implement it in Android.
Be familiar with the concept of data/view binding. Have basic knowledge of the Kotlin Programming language. Understand the basics of Android development. To follow along with this tutorial, you need to: Initializing Paper in an application class. Instead, it has the field as the main element of the database. An example is the phone book which has no records for each person. In Android, there are several databases such as SQLite, Room, SQLDlight, Datastore, SharedPreferences, and Realm database.Īlthough most people think that all databases are composed of fields and records, databases held on Paper contain fields and have no records. A database is an organized collection of data that is stored in computer systems.
