The intent of this guide is to give you an idea about the Android development landscape and to help guide your learning if you are confused. Before we start, please note that the roadmap is opinionated, and you might have different opinions than those of the author. Having said that, [we would love to hear your opinions](https://github.com/kamranahmedse/developer-roadmap/issues/new) and incorporate them in the roadmap if suitable.

There are multiple ways to develop applications for the android; you can go down the path of hybrid application development where [flutter](https://flutter.dev/), [react-native](https://reactnative.dev/), or [NativeScript](https://www.nativescript.org/) are the most common contenders. Flutter uses Dart, whereas React Native and Native Script rely on JavaScript. Answering the question of hybrid vs native is out of the scope of this roadmap. This roadmap is focused on the native Android apps development but if you are interested in learning any hybrid framework, my personal preference is [react-native](https://reactnative.dev) and I would recommend you to checkout the [Frontend Developer Roadmap](/frontend).

# Observable Pattern
# Observer Pattern

The observer pattern is a software design pattern in which an object, named the subject, maintains a list of its dependents, called observers, and notifies them automatically of any state changes, usually by calling one of their methods.

Angular uses the Observer pattern which simply means — Observable objects are registered, and other objects observe (in Angular using the subscribe method) them and take action when the observable object is acted on in some way.

Database Design is a collection of processes that facilitate the designing, development, implementation and maintenance of enterprise data management systems. Properly designed database are easy to maintain, improves data consistency and are cost effective in terms of disk storage space.
The main objectives of database design in DBMS are to produce logical and physical designs models of the proposed database system.

# Sql basics
# Sql basics

SQL stands for Structured Query Language. SQL lets you access and manipulate databases
SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987.

Although SQL is an ANSI/ISO standard, there are different versions of the SQL language.

However, to be compliant with the ANSI standard, they all support at least the major commands (such as SELECT, UPDATE, DELETE, INSERT, WHERE) in a similar manner.

# Database fundamentals
# Database fundamentals

A database is a collection of useful data of one or more related organizations structured in a way to make data an asset to the organization. A database management system is a software designed to assist in maintaining and extracting large collections of data in a timely fashion.

A **Relational database** is a type of database that stores and provides access to data points that are related to one another. Relational databases store data in a series of tables.

**NoSQL databases** offer data storage and retrieval that is modelled differently to "traditional" relational databases. NoSQL databases typically focus more on horizontal scaling, eventual consistency, speed and flexibility and is used commonly for big data and real-time streaming applications.

# Codefirst migrations
# Code First Migrations

Code First Migrations is a feature of Entity Framework that enables you to change the model classes in your application and then propagate those changes to the database. When you use Code First Migrations, Entity Framework generates the necessary SQL commands to update the database schema to match the model classes.

To use Code First Migrations, you need to enable it in your Entity Framework application. This can be done by adding a reference to the Entity Framework Migrations NuGet package, and then enabling Migrations in your application.

Once Migrations is enabled, you can use the Package Manager Console to add a new migration to your application. This will generate a class that contains the necessary SQL commands to update the database schema. You can then use the Update-Database command to apply the migration to the database.

# Dapper
# Dapper

Dapper is a lightweight object-relational mapper (ORM) for the .NET framework. It is designed to provide fast and simple access to data stored in a database, by mapping the data to objects in the application.

Dapper helps you to write efficient and concise code for interacting with databases, without the need for a full-featured ORM like Entity Framework. It provides a set of extension methods for the IDbConnection interface, which you can use to execute SQL queries and map the results to strongly-typed objects.

# Memory cache
# Memory cache

Memory caching (often simply referred to as caching) is a technique in which computer applications temporarily store data in a computer’s main memory (i.e., random access memory, or RAM) to enable fast retrievals of that data. The RAM that is used for the temporary storage is known as the cache.

# Entity framework cache
# Entity framework cache

Entity Framework Core(EF Core) is a cross-platform version of the popular Entity Framework data access technology that is lightweight, extendable, and open source.
It can be used as an object-relational mapper (O/RM), which can Allow .NET developers to use .NET objects to interact with a database and Removes the requirement for most of the data-access code that is generally required.

However, during peak loads, high-transaction .NET Core apps using EF Core have performance and scalability problems in the database tier. This is because, although you can scale the application layer by adding more application servers, you can't scale the database tier by adding more database servers.
