There is also the ORM realm.io, which is also very popular in Android. IвЂ™ve been there and battled the fires in production. Upgrading databases in Android is difficult. Looking at the Android Developer documentation can also lead you down a rickety path. There are many open source ORM projects for Android, such as greenDAOВ and OrmLite,В with the goal of manipulating an SQLite database more easily. When using your own SQLite database in Android, most people take for granted future releases of the application they are working on. ORM will allow you to create an extra abstraction layer, so you can manipulate a relational database (like SQLite!) with objects. Well, an object-relational mapping is a programming technique that allows developers to deliberately create the illusion of manipulating an object-oriented database, when in reality, you're working with a relational database. Now, ORMs have begun to appear to compensate for these problems! Secondly, because you natively needed a lot of code to transform the result of a query into a Java object. This means that if there is an error, you'll only see it when your app crashes! рџ± Now that it is installed, we can create a new database in the following way:: sqlite3 example.

Because it takes up so little space ( the source codeВ is less than 2 MB), SQLite can be found in a lot of software such as web browsers, embedded systems, and operating systems like Android. Unlike traditional database servers such as MySQL, PostgreSQL or Microsoft SQL Server, the entire database is stored in a file (not on a remote server). SQLite isВ a relational database engine that can be fully manipulated with the SQL language. In Android, you have the ability to store this data in a database called SQLite.

Generally, this type of data is stored in a relational database. Well, not really! рџ‰В When I say structured data, I mean data that has strong relationships between them.

ItвЂ™s easy, we did it in the last section! Open a file, and store our structured data inside, right? рџ™‚
