-Cube was designed to work with all SQL-enabled data sources, including cloud data warehouses like Snowflake or Google BigQuery, query engines like Presto or Amazon Athena, and application databases like Postgres. Cube has a built-in caching engine to provide sub-second latency and high concurrency for API requests.

 ## Why Cube?
 
-If you are building a data application—such as a business intelligence tool or a customer-facing analytics feature—you’ll probably face the following problems:
+If you are building a data application—such as a business intelligence tool or a
+customer-facing analytics feature—you’ll probably face the following problems:
 
-1. __SQL code organization.__ Sooner or later, modeling even a dozen metrics with a dozen dimensions using pure SQL queries becomes a maintenance nightmare, which leads to building a modeling framework.
-2. __Performance.__ Most of the time and effort in modern analytics software development is spent providing adequate time to insight. In a world where every company’s data is big data, writing just SQL queries to get insight isn’t enough anymore.
-3. __Access Control.__ It is important to secure and govern access to data for all downstream data consuming applications.

-Cube has the necessary infrastructure and features to implement efficient data modeling, access control, and performance optimizations so that every application can access consistent data via REST, SQL, and GraphQL APIs. Achieve insights from raw data within minutes, and get an API with sub-second response times on up to a trillion data points.

 The client provides methods to solve common tasks:
 
-**Abstract from the transport and query data.** You can [fetch data](https://cube.dev/docs/@cubejs-client-core#load)  from Cube.js Backend or subscribe to [real-time updates](https://cube.dev/docs/real-time-data-fetch) regardless of the protocol, be it HTTP or WebSockets.

-**Transform data for visualization.** You can [pivot](https://cube.dev/docs/@cubejs-client-core#pivot) the result set to display as a [chart](https://cube.dev/docs/@cubejs-client-core#chart-pivot) or as a [table](https://cube.dev/docs/@cubejs-client-core#table-pivot), split into [series](https://cube.dev/docs/@cubejs-client-core#series) or [table columns](https://cube.dev/docs/@cubejs-client-core#table-columns).

 ## Example Usage
 
 Here are the typical steps to query and visualize analytical data in Angular:
 
-- **Import `@cubejs-client/core` and `@cubejs-client/ngx` packages.** These packages provide all the necessary methods and convenient Angular tools.
-- **Create an instance of Cube.js JavaScript Client.** The client is initialized with Cube.js API URL. In development mode, the default URL is [http://localhost:4000/cubejs-api/v1](http://localhost:4000/cubejs-api/v1). The client is also initialized with an [API token](https://cube.dev/docs/security), but it takes effect only in [production](https://cube.dev/docs/deployment/production-checklist).
-- **Query data from Cube.js Backend and Transform data for visualization.** Use [CubejsClient](https://cube.dev/docs/@cubejs-client-ngx#api) to load data. The client accepts a query, which is a plain JavaScript object. See [Query Format](https://cube.dev/docs/query-format) for details.
-- **Visualize the data.** Use tools of your choice to draw charts and create visualizations.
