In contrast to its predecessor, Realm is much easier. And here are the results of our comparison: 1. Cleveroad has also tried out this brand new tool. Developers have already found several advantages of Realm over SQLite. This tool is used by such big companies like IBM, CISCO, Amazon, Google, and Intel. SQLiteĪppeared not long ago, Realm is a good alternative for SQLite. Massive structure and complexity of SQLite forced developers to search for a simpler alternative that won’t rest upon SQL. But when you start using SQLite for developing Android apps, applying this tool may turn into a nightmare. ComplexityĮxperienced SQL coders will have no difficulties with solving upcoming problems. To solve this problem, add several SQLite extensions or encrypt information right before it is put it on the journal. Don’t put this file into the web root and think twice when you set a file permission. To prevent that, protect the database on the file level. But in practice, it is a high risk to lose data when any rogue process will open and rewrite the database file. SQLite DB is stored in a single fileĭevelopers can put SQLite DB file wherever they want in the directory hierarchy. But bear in mind that in this case app crash will cause irreparable damage to the database. You may think that turning journal off can be a good solution. But sometimes they stay, and it may cause data corruption. As a rule, they are kept for a certain period of time and deleted after a transaction. Temporary journal files allow you to rollback when something went wrong. Since security is of a great importance for any mobile application, you should definitely know about this issues before using SQLite. SecurityĮven though its long development process, SQLite still has a couple of security issues. The process is quite similar if you want to add or delete constraints. After get rid of the old table and change the name of the new one. Then copy info from one table to another. When you eager to do the migration, you have to take several steps.įirst, create a new table based on the old one. The first and foremost con is the inability to rename or delete the column in a few lines of code. Newbie developers have problems with this because of a lack of experience with using SQL.Īnother weak side is data migration. If you want your application to work seamlessly with a big scope of data, it is a necessity to write complex queries. There is no denying that the longer your app is on market, the more data need to be stored. Otherwise, you may face the following challenges: In case your project is not so complicated, you can opt for SQLite. SQLite drawbacksĮven the most powerful tools have drawbacks. Let’s find out the main reasons why Realm now bypasses time-tested SQLite. Now, this tool continues to gain popularity among mobile developers. This DB works seamlessly with Java, Swift, Objective-C, Xamarin, React Native. Realm is widely used for mobile development, especially among newbies in Android development. Created from scratch, this tool works on its own persistence engine. In 2014 its creators renamed it to Realm and released the beta version of their brainchild. Its development began in 2010, its first name was TightDB. This tool positions itself as a DB management system that can easily replace SQLite. Thousands of mobile apps were built using this tool. SQLite is primarily geared toward storing all data on devices and moving away from common client-server architecture. It was developed back in 2000 by Richard Hipp who also created Fossil version control system. This embedded database remains the most widely utilized SQL DB engine. Let's take a closer look at both databases. But when data needs to be saved on user’s device, there are 2 major options that will come in handy. When developers start looking for the best database, they can find a plethora of solutions, especially when they want to store all needed information on the server. He enjoys telling about tech innovations and digital ways to boost businesses. Vitaly is a technical writer at Cleveroad, a web and app development company in Ukraine. It is vital for every Android developer to choose the right database that will fit the product and not destroy it. The first and foremost question is how to store information. And when thinking through the client-side, like an eye-catching design and usability, it’s also crucial to figure out what will be under the hood. When creating an Android app, every developer faces a lot of issues.
