Popular programming languages

If you learn how to code in Kotlin, you can choose from hundreds of jobs on the market.

Apps for Android operating system are built on Kotlin. Almost all of the apps you use on your Android phone run on Kotlin.

(with the help of Kotlin)

A good Kotlin programmer has to be able to write good, clean Kotlin code that solves a problem.

Frameworks

A framework is a collection of languages, libraries['laibr(a)rIz], and utilities[ju:'tIlItIz] designed to help developers build applications.

Laravel is a web application framework with clear and elegant syntax['sIntaeks].

• utility: a small program that provides an addition to the capabilities provided by the operating system

• syntax: rules that define the structure of a language

在计算机中，“utilities”一词通常指的是实用程序或实用工具。这些工具旨在提供辅助功能，帮助用户完成特定的任务，从而提高计算机的日常使用效率和功能性。这些实用程序或工具可以涵盖多个方面，如系统管理、文件管理、性能优化、网络安全等。它们通常以软件的形式存在，可以是操作系统自带的，也可以是第三方开发的。具体来说，计算机中的“utilities”包括但不限于以下几种类型：

• 系统管理工具：如任务管理器、磁盘清理、磁盘碎片整理等，用于维护和优化系统性能。
• 文件管理工具：如压缩/解压缩工具、文件加密/解密工具、文件搜索工具等，用于文件的处理和管理。
• 网络管理工具：如网络监视器、端口扫描器、网络配置工具等，用于网络的监测和管理。
• 性能优化工具：如内存优化器、启动项管理器等，用于提升系统的运行速度和稳定性。

utility 需要和 utilization 作区分。比如：Resource utilization 资源利用率。

On one hand Django ensures rapid['raepId] development[dI'velopmant], fast processing['prausesIn] and scalability[,skerla'bllati], whereas on the other hand it has monolithic[,mona'lI0Ik] nature and is not suitable for smaller projects.

• processing : Manipulation of data by a computer(e.g. conversion of raw data into machine-readable form)

• Azure ['æe3ə] SQL Synapse Analytics
• MongoDB
• Redshift
• PostgreSQL ['paust'gres ( kju:' εl)]
• Snowflake
• Splunk

This layer of the stack consists of relational[rI'leI(a)nal] and non-relational databases, data warehouses['weahausiz], and data pipelines that allow you to databases, data warehouses['weahausiz], and data pipelines that allow you to store and query['kwI(a)rI] all of your real-time and historical data.

data warehouse['weahaus] DW or DWH : a system used for reporting and data analysis. It is considered a core component of business intelligence.

query['kwI(a)rI]: a request for data from a database table or combination of tables. This data may be generated as results returned by SQL.
