Some applications deserve to create a way to manage organized content, for this reason it is sometimes necessary to manage a SQLite database to maintain better control of the contents.

SQLite it is a universal format used by private and public companies around the world; therefore, it is important that the application you are developing is capable of handling this type of format.

The SQLite program is very useful when we will use the Android Studio program; In case you don't know, Android Studio is a program that allows you to develop and create applications, you can get this program for Windows, Linux and MacOS



Although you can also find other tools to create mobile applications.

How to create a SQLite database?

First of all, you can create your own database template in any application, such as Microsoft Office Excel, which is one of the most popular tabs.

Now you just have to save it in .csv format, to continue you will need an application called " SQLite Expert Pro ", Enter it and then click on" Fillet " > " New Database ".

This new database must be created in the folder " asset ”Of your Android Studio project. Once created, you have to click on the option " Import / Export ”>” File.cs v ”and select the database you created.

How to bring the database to the application?

Once you have entered your project, you must create the screenshot where the database will be displayed, use buttons and titles to give it a better view, remember to assign the necessary data so that the table where the data will go is generated, finally just load the data from the folder "Assets" And that's it.



Advantages of databases

Remember that not all applications are developed solely to be interactive, some count as a sort of catalog, where the data can be viewed in a simple and orderly way.

This is why the use of databases is so important; For example, if an app is developed to find doctors near an area, it must have a database of them, with at least their media, name and address.

For this it is necessary that the data are correctly ordered; this way they can be viewed more easily and can help you have a better experience use of the app.

In addition, a database can also be used to view the scores of a sports match or to establish completed or uncompleted activities in a company.

The fact is that the use of databases is quite extensive thanks to their functionality; allowing to facilitate the monitoring of certain actions or access to some information.

disadvantages

Using a SQLite database in an app it's complicated;  if you see it from the point of view that it requires a large number of coding processes to be able to organize the tables in which the data will be displayed.

Complicates also some use of the application;  Because, if the database is not in the cloud, but is part of the application, this can lead to an increase in the space required for its use.


This could complicate the marketing of the app; because very few people want to cover a large part of their memory with a database that few can use.

 

The use of applications on mobile devices has become one life tool in today's world;  applications that provide us with all the data we need.


For this reason, those apps that have very useful databases yes have made their way into the market; as an app for exercises or cooking recipes.

Finally, we hope that we have cleared all your doubts and that this tutorial is of great help to you so that you can start using a SQLite database in your applications that deserve it.

If you wish, you can also purchase the Android Studio program for your Android phone, for this you just have to download and install the emulator. Once the program is installed, have fun creating your first application.
