Best Practices for Using Database in Mobile Applications

Abhigyan Singh 04th Apr 2021

Creating a mobile application is in demand among businesses. Startups and large companies aim to establish their own mobile app to scale their operation, boost productivity, and improve results.

However, the mobile application requires data in a phone memory that’s been stored locally. What are the best options? Don’t worry as you have come to the right place. Read on for more information!

What Is Unity?

Unity is the most common choice for many businesses. Of course, if it is your first time to hear about Unity, you are probably holding back. As a business owner, you want the best for your mobile application. But why do people rely on Unity? There is a reason, of course!

Unity is simply a tool designed to create complicated graphic mobile apps. It is developed over the development tools of iOS, Windows, Android, and other platforms in today’s market. That means you can not only build but also ship apps pertaining to any of these platforms.

You can use it to integrate with various tools and applications like integrating chartbeat, & others.

Unity’s existential purpose is to build games that demand and focus on graphic rendering. It goes beyond data processing, in other words. But do not lose hope, as it is still ideal for those who plan to create a regular app. It will not be a disappointment.

Why Should You Choose Unity? 

There are platforms you should take advantage of, so why Unity? Here are some reasons you should trust Unity:

A Perfect Choice for Those Who will Build a Gaming Platform. If you have been searching for the best option, your long wait is finally over with Unity.

Recognized As a Cross-Platform. Yes, you read it right. Unity is a cross-platform. What does it mean, though? That means you can target Play Store and App Store without too many troubles.

It Supports Two Languages. These include Javascript and C#. Whether you are using C# or Javascript, Unity will be an excellent investment you can ever have this 2021.

Types of Databases

There are two types of databases, including Structured Query Language (SQL) and No-SQL. Structured Query Language is the go-to option for many. It works by placing data in tables. On the contrary, No-SQL does not have any structure or table. It basically stores data in objects. Compared to SQL, No-SQL requires extra resources to maximize its functionality. That is why experts prefer SQL instead.

In terms of resources, databases are originally made for servers and computers to store a massive amount of information.

Unfortunately, mobile platforms do not have that computing resources. But worry no more. This is where SQLite comes to fruition.

What Makes it Different from the Rest?

With a variety of options out there, SQLite stands apart from the competition because:

It is Lightweight. You do not need to invest in resources high in memory or storage.

It has Less Data Types. Who wants a platform that does not have as many data types as it requires? SQLite will be a fantastic solution.

It Does Not Allow Functionalities. In multi-user access, it allows functionalities. On the contrary, SQLite is different.

It Has Been the Sought-After Choice for Mobile Developers. Yes, it is the leading option for a growing number of developers in this industry.

Recommended by Android. Even Android recognizes SQLite for its reliability and consistency. So, what are you waiting for? Give it a try and see how it differs from the rest.

Quick and Easy Steps in Setting up SQLite in Unity

You probably have tried to use Unity and other types of databases. If yes, you are now ready to set up SQLite in Unity. But for beginners, there is nothing to be afraid of. You can find a lot of comprehensive and step-by-step video tutorials on YouTube and other platforms online.

Once you know the things you need to learn, follow these steps to set up SQLite in Unity finally:

Copy Paste the Plugins Folder

It usually consists of the libraries for SQLite. It includes different folders, named Android, x64, and x86. In this step, there is no complicated procedure to follow. Just copy the folder and paste in a blank Unity project.

Create a Behavior and Scene Script Within the Workspace

After copy-pasting the plugins folder, create a behavior and scene script in the workspace. Well, it is easy. All you need to do is to right-click in the workspace. Then, select C# Script and Scene as well. That’s it.

Open a File Called SqliteTest

Unlike the two first steps, this one may be difficult as it requires a coding experience. If you do not have any coding experience, there is nothing wrong with asking for help from someone. But since you are a mobile app developer, coding may be your specialty.

Establish a New Database

To establish a new database, follow this code:

String connection = “URI=file:” +Application.persistentDataPath +“/My_Database”;
IDbConnection dbcon = new SqliteConnection (connection); 
Dbcon.Open (); 

Create a Table in Your Database 

IDbCommand dbcmd;
IDataReader reader;
dbcmd = dbcon.CreateCommand();
string q_createTable = 
"CREATE TABLE IF NOT EXISTS my_table (id INTEGER PRIMARY KEY, val INTEGER )";
dbcmd.CommandText = q_createTable;
reader = dbcmd.ExecuteReader();

Put Some Values in Your Table

IDbCommand cmnd = dbcon.CreateCommand();
cmnd.CommandText = "INSERT INTO my_table (id, val) VALUES (0, 5)";
cmnd.ExecuteNonQuery();
Close the Connection especially when You Are Done
IDbCommand cmnd_read = dbcon.CreateCommand();
IDataReader reader;
string query ="SELECT * FROM my_table";
cmnd_read.CommandText = query;
reader = cmnd_read.ExecuteReader();
while (reader.Read()){
Debug.Log("id: " + reader[0].ToString());
Debug.Log("val: " + reader[1].ToString());
}
dbcon.Close();

Select MainScene in Unity

After that, add an empty GameObject in the scene. Then, do not forget to drag and drop your SqliteTest script.

Tap the Play Button

That’s it! You are all set. You already have an SQLite Unity database that is compatible to any iOS and Android-powered devices. Whether you have something to ask or verify, please feel free to contact an experienced and reliable professional to make your experience trouble-free, convenient, and satisfying. Enjoy creating mobile apps for your business and your target market. Failure is also part of the process. But you will get there!
