The most important is that we’ll create it in such way, so it accepts clear SQL statements, and if you had worked with SQL in the past, you’ll definitely know what to do here too.īesides the database class that we’ll develop, we’ll also create a sample application to test it and to see it in action. Going into more details, the database class that we will implement will be capable of executing all the standard SQL queries ( select, insert, update, delete). Unfortunately, even though SQLite is supported by Apple, a mechanism or a pre-made database management library does not exist. Instead, my plan is to implement a database class step by step, which will utilize the most important features of the SQLite library, but it will also become a reusable tool for your own applications. It has continuous support by developers in the whole world and new features are always added to it.įocusing now on our tutorial, let me start by stating that my goal is not to show you how to become a SQLite expert.It’s fully supported by Apple, as it’s used in both iOS and Mac OS.It works as part of the app itself, and it doesn’t require extra active services.It contains an embedded SQL engine, so almost all of your SQL knowledge can be applied.However, its greatness lies mostly to these factors: SQLite is not as powerful as other DMBSs, such as MySQL or SQL Server, as it does not include all of their features. Nowadays, SQLite lives its third version, so it’s also commonly referred as SQLite 3. On the contrary, the app runs it as an integral part of it. Note that it does not consist of a separate service or daemon running on the background and attached to the app. It is contained in a C-library that is embedded to the app that is about to use it. The database that can be used by apps in iOS (and also used by iOS) is called SQLite, and it’s a relational database. Also, if you were used to working with other databases or database management systems (DBMSs), then you’ll really appreciate the fact that you can keep applying your SQL knowledge in the iOS platform as well. For programmers who love working with databases and SQL, this is the favorite data-managing method at 90% of the cases, and the first think that crosses their minds when talking about data. Indeed, making use of a database can solve various kind of problems that should be solved programmatically in other cases. However, when working with large amount of data, the preferred method it seems like a one-way path: That is the use of a database. There are various solutions offered to developers for storing and managing data, and usually each one of them is suitable for different kind of applications. Most of the apps handle some sort of data, no matter in what format they are, and always perform some actions upon it. IOS How to Use SQLite to Manage Data in iOS AppsĪmong the numerous applications existing on the App Store today, it would be hard for someone to find more than a few of them that do not deal with data.
