2.2 History of Firebase

Picture 2 2: History

In 2011, James Tamplin and Andrew Lee introduced Evolve This was aplatform with a relatively simple structure designed to provide essential APIs forintegrating chat features into websites However, they soon realized that the platformwas being used not just for chat but also for transmitting application data.Subsequently, they developed Envole, ultimately leading to the creation of Firebase

By April 2012, Firebase was globally announced as an independent company Inthe subsequent years, Firebase continued to attract investments and rolled out variousnew products

By October 2014, Firebase had officially been acquired by Google, becoming aversatile application across both mobile and web platforms

Initially, Firebase was the invention of James Tamplin and Andrew Lee, butthrough multiple rounds of fundraising, it officially became a part of Google'sownership in 2014.

2.3 Pros and Cons:

Picture 2 3: Pros and Cons

2.3.1 Pros:

- Free and convenient: You can utilize basic features of Firebase for free

through the Spark service plan For more advanced features, there is a relatively highcost involved Additionally, the process of registering a Firebase account isstraightforward You can register a Firebase account through your Google account

- Easy to use and integrate: Firebase provides a user-friendly and easily

understandable interface After registering your account, simply log in to start utilizing

Firebase features right away Firebase also offers a diverse storage backend with auser-friendly interface, making it convenient for you to choose and manage yourresources.

Additionally, Firebase integrates functionality to assist in establishing criteriafor improving the ranking of your application This not only enhances accessibility forcustomers but also contributes to an increase in traffic

- Meet user needs: Firebase is an integral part of the Google ecosystem.

Consequently, Google continually leverages and extensively develops the strengths andfeatures of Firebase to create services that meet user needs

According to Gartner, approximately 30% of businesses are incorporatingmachine learning (ML) into their workflows Recognizing this trend, Firebase providesmachine learning developers with APIs for various features on the mobile platform.This facilitates the development of applications in the most effective manner

Picture 2 4: Pros and Cons 2.0

- Continuously updated and cross-platform: Firebase undergoes continuous

updates and experiences rapid development, enabling developers to save time inboth the development and marketing of applications Additionally, Firebase is amulti-service platform, evident in its diverse range of services designed for websitedevelopment Developers can easily choose between databases like Firestore orRealtime based on their preferences This versatility contributes to Firebase's appealfor developers seeking efficient and customizable solutions

2.3.2 Cons:

- Limits on application size: Firebase is a component within the Google

ecosystem, operating as a subdomain of Google It's worth noting that Firebase iscurrently restricted in certain countries, including China Furthermore, the entire

infrastructure of Firebase operates on Google Cloud This implies that users cannotrun Firebase applications on cloud service providers other than Google Cloud.

- Limited customization capabilities: Firebase stores its database in JSON

format and doesn't support SQL This can pose challenges in data migration andmanipulation Additionally, Firebase is not an open-source platform, meaningdevelopers cannot modify its source code, hindering the ability to tailor the product

Moreover, developers lack access to the source code, making it difficult toswitch to other providers for larger applications Transitioning to a differentprovider would require rebuilding the entire backend from scratch, addingcomplexity to the process

- Weak security: One of the security weaknesses in Firebase is the storage of

the entire database in JSON format While JSON has the advantage of beinglightweight, language-independent, and user-friendly, in some cases, it can beconsidered a security concern, potentially leading to issues related to informationsecurity

2.4 Realtime Database and Cloud Firestore:

2.4.1 What is Firebase Realtime Database:

Picture 2 6: Firebase Realtime Database

Firebase Realtime Database is a type of cloud-hosted NoSQL database thatenables you to store and synchronize data Notably, the data is stored in JSON formatand is synchronized in real-time across all connected devices

When developing cross-platform applications using SDKs for iOS, Android, andJavaScript, Firebase's Realtime Database ensures that all clients share a version of the

database and automatically updates with the latest data This ensures responsivenessfor mobile applications that require real-time synchronization of state across devices,providing an efficient solution with low latency.

2.4.2 Main function of FRD:

Picture 2 7 Realtime Database functions

Realtime: Firebase employs data synchronization, ensuring that whenever datachanges, all connected devices receive the updates immediately

Offline: Firebase ensures that applications remain functional even when offline,

as the Firebase Realtime Database SDK stores your data locally Upon reestablishing aconnection, the device is updated with any changes it missed and synchronizes thecurrent data with the server

Multi-device Usage: Firebase Realtime Database can be accessed directly frommobile devices or web browsers

Scalability through Database Combination: With Firebase Realtime Database onthe Blaze plan (paid version), scalability is achieved by combining multiple databaseswithin the same Firebase project.

2.4.3 How Firebase Realtime Database works ?

Picture 2 8 : Realtime Database works

Firebase Realtime Database enables you to easily build diverse and secureapplications with a database directly from the client Data is maintained locally, andeven when the application is offline, real-time events continue Upon devicereconnection, the Realtime Database automatically synchronizes local data changeswith data from the server and automatically resolves any conflicts

Firebase Realtime Database provides security rules to determine the datastructure and read-write access, often combined with Firebase Authentication features

As a NoSQL database, Realtime Database is optimized for performance,avoiding the limitations of relational databases Designed for quick responsiveness,

Realtime Database allows you to build an excellent real-time experience that can servemillions of users without concerns about responsiveness.

2.4.4 What is Cloud Firestore ?

Picture 2 9 : Cloud Firestore

Cloud Firestore is Firebase's newly developed database tailored specifically formobile applications It builds upon the foundation of the Realtime Database butintroduces a new and more intuitive data model Compared to the Realtime Database,Cloud Firestore is more feature-rich, faster, and boasts superior scalability

Similar to Firebase Realtime Database, it facilitates data synchronization acrossclient applications through real-time updates and provides offline support for mobileand web devices Cloud Firestore also integrates seamlessly with other Firebase andGoogle Cloud Platform products, including Cloud Functions

2.4.5 Main functions of Cloud Firestore:

Picture 2 10 : Cloud Firestore functions

Flexibility : Cloud Firestore supports flexible data structures with hierarchicaldata modeling Your data is stored in documents, organized into collections.Documents can contain complex objects

Abstract Queries : You can use queries to retrieve individual documents or fetchall documents in a collection that match your query parameters Your queries caninclude multiple filters, combining filters, and sorting

Real-time Updates : Cloud Firestore employs data synchronization to updatedata across all connected devices It is also designed to perform one-time fetch queriesefficiently

Offline Support : Cloud Firestore stores data locally, allowing the application towrite, read, listen, and query data even when the device is offline When the device

comes back online, Cloud Firestore synchronizes all local changes to the CloudFirestore.

Scalability : Derived from the Google Cloud Platform, Cloud Firestore isdesigned to handle the most challenging database needs of the world's largestapplications, ensuring scalability for various use cases

2.4.6 How Cloud Firestore works ?

Picture 2 11 : Cloud Firebase works

Cloud Firestore is a cloud-hosted NoSQL database that can be accessed directlythrough SDKs by iOS, Android, and Web applications Additionally, Cloud Firestore isalso available in SDKs for Node.js, Java, Python, and Go, as well as through REST andRPC APIs

Following the NoSQL data model of Cloud Firestore, data is organized intodocuments that map to values These documents are structured within collections,providing a way to organize data and execute queries

To secure access to your data in Cloud Firestore, you can use FirebaseAuthentication for Android, iOS, and JavaScript, or Identity and Access Management(IAM) This ensures data security and control over who can access it.

2.4.7 Difference between Realtime Database and Cloud Firestore.

Picture 2 12: Difference between Realtime Database and Cloud Firestore.

- Data model:

Picture 2 13: Data model:

Both are NoSQL databases Realtime Database stores data in a JSON tree,making it simpler and easier for basic data storage However, it can becomechallenging to organize complex and hierarchical data when scaling

In contrast, Cloud Firestore stores data in documents organized withincollections Simple data is stored within documents, similar to JSON data storage Forcomplex data, hierarchical structuring can be achieved through subcollections CloudFirestore requires less data normalization and provides more flexibility in how data isorganized and accessed

- Real-time data and offline support:

Picture 2 14: Real-time data and offline support.

Both are the first databases supporting the Realtime SDK and have thecapability to store data locally The Realtime Database only allows offline mode formobile applications on iOS and Android, whereas Cloud Firestore provides offlinesupport for iOS, Android, and even web applications

- Query:

Data can be retrieved, sorted, and filtered from any database through queries

Realtime Database supports queries with sorting, filtering, and limitingfunctionalities In a single query, you can only perform sorting or filtering, not both, onone property

Cloud Firestore supports composite index queries with sorting, filtering, andmerging Cloud Firestore allows the simultaneous use of both filtering and sorting on a

property in a single query The default query type is an index type, where queryperformance scales proportionally to the size of your result set and is independent ofthe data size.

- Stability and performance:

Realtime Database is a mature product with high stability and exhibits very lowlatency, making it suitable for data synchronization

Cloud Firestore offers even higher stability than Realtime Database because itdistributes data across servers globally

- Ability of extension:

Realtime Database can handle up to 100,000 concurrent connections andperform 1,000 writes per second in a single database, so scaling requires datadistribution across different databases

On the other hand, Cloud Firestore scales automatically and seamlessly

- Security:

Picture 2 15: Security of Cloud Firestore and Realtime Database

Realtime Database relies on conventional authentication rules

Cloud Firestore provides a security system that is simple yet more robust.Mobile and web applications utilize the security rules of Cloud Firestore, while server-side applications use Identity and Access Management (IAM)

-Final result:

Both databases can be used together in a Firebase application or project

Cloud Firestore introduces additional features, improved performance, andscalability, with the promise of integrating new features in the future

If you're looking for advanced queries, stronger security rules, and optimizedperformance with some additional advanced features, Cloud Firestore is the suitable

choice Just keep in mind the differences mentioned above if you decide to use bothdatabases or choose one for your mobile application.

2.5 Authentication:

Picture 2 16: Authentication

Firebase Authentication is a feature used to verify users through methods such

as passwords, phone numbers, or linked accounts like Google, Facebook, Twitter, etc

User authentication plays a crucial role in app development However, dealingwith various authentication methods can be time-consuming and labor-intensive

Firebase Authentication addresses this issue by providing a mechanism forsharing IDs across applications, making it easier for users to access and interact withproducts Therefore, it is a highly valuable and convenient feature

2.7 Test Lab:

Picture 2 18: Test Lab

Firebase Test Lab is used to test applications on the cloud platform

By utilizing Test Lab, we can test the functionality of the application acrossvarious devices, allowing us to verify how the app will run on the actual devices used

by users

2.8 Cloud Messaging (FCM):

Picture 2 19: Cloud Mesaging

With Firebase Cloud Messaging, you can send and receive messages for free.The concept of "sending messages" here also refers to pushing notifications

When a new message is sent, users can receive notifications For example, foriPhone users, when there is an email or notification from an application, a small redcircle will appear in the top right corner of the app's icon, or more conveniently, withinthat red circle, the number of notifications or new messages will be displayed

Furthermore, we can also set up messages to be sent only to specific recipients.For instance, sending a notification requesting product feedback to customers whoregularly use the product

2.9 Hosting:

With Firebase Hosting, you can use web pages for both your iOS and Androidapplications.

With the advantages of fast and simple operations, high security, FirebaseHosting helps developers establish applications more easily compared to the process ofself-deployment or using external server services.

2.10 Remote Config:

Picture 2 21: Remote Config

Firebase Remote Config allows you to alter the UI and functionality of an appwithout the need for an app update

This is done by initially setting default values for the app's interface andfunctionality Later, the Remote Config REST API or Firebase Console can be utilized

to override these default values with new settings
