 ### Introduction to SAP HANA Cloud, data lake
 
-SAP HANA Cloud, data lake is one of the components that make up SAP HANA Cloud. It's composed of two different components, the **Data Lake, IQ** and **Data Lake Files**. The Data Lake, IQ enables efficient storage and high-performance analytics of relational data at petabyte scale. It leverages the technology of SAP IQ, which many customers already know from the on-premise world.
+SAP HANA Cloud, data lake is one of the components that make up SAP HANA Cloud. It's composed of two different components, the **Data Lake Relational Engine** and **Data Lake Files**. 
 
 With SAP HANA Cloud, data lake, you can ingest data from multiple sources, as well as non-SAP cloud storage providers, at high speed. It's an integrated part of SAP HANA Cloud, providing common security mechanisms, tenancy models, and tools operating within SAP HANA Cloud.
 
 SAP HANA Cloud, data lake was built to be scalable and accommodate increases in data volume, in user count, and the complexity of workloads. This tutorial will focus on using SAP HANA Cloud, data lake as a standalone component of SAP HANA Cloud.

+### Data Lake, Data Lake Relational Engine and Data Lake Files
 
 The two main components of SAP HANA Cloud, data lake are:
 
 
-1.  **Data Lake, IQ**: Data Lake, IQ is an efficient disk-optimized relational store, based on SAP IQ on-premise. It's enabled by default when you provision a data lake instance, whether it's standalone or managed by an SAP HANA database instance within SAP HANA Cloud.
+1.  **Data Lake Relational Engine**: Data Lake Relational Engine enables efficient storage of structured data and high-performance analytics of relational data at petabyte scale. It's enabled by default when you provision a data lake instance, whether it's standalone or managed by an SAP HANA database instance within SAP HANA Cloud.
 
 2.  **Data Lake Files**: Data Lake Files service provides a secure, managed object storage to host structured, semi-structured and unstructured data files. You can query files in a relational format stored in data lake files by using the Data Lake's **SQL on Files** feature. This allows you to analyze the data with a low-cost strategy, given that this data has an unknown value. It is also easy to share this data with other processing tools. It's enabled by default when you provision a data lake instance, whether it's a standalone or managed by an SAP HANA database instance.
 
 The Data Lake Files component is currently not available in the free tier model or trial.

 ### How to use a data lake
 
 SAP HANA Cloud, data lake can be provisioned and used in two different ways:
 
 
--	**Managed data lake**: the data lake is provisioned as part of the SAP HANA Cloud, SAP HANA database provisioning. A remote connection between the SAP HANA database and the Data Lake, IQ is then automatically created. The easiest way to access the data in a managed data lake is to use SAP HANA virtual tables using the SAP HANA Database Explorer. You can, however, also access the data lake independently.

 -	**Standalone data lake**: the data lake is provisioned independently of any other SAP HANA Cloud services, and therefore it is not automatically connected to any other SAP HANA Cloud instances you might have. You can access your data within the data lake with SAP HANA Database Explorer, dbisql, isql, or any of the supported data lake client interfaces.

-The monitoring views and **`sp_iqsysmon`** are intended for very different reporting timescales.

Rather than monitoring over a defined period, monitoring views start gathering performance metrics at server startup and reports the current state of the system.

 It is beneficial to monitor changes in performance over time and this can be achieved by regularly checking the monitoring views at regular intervals. Any metrics moving out of their normal ranges should be evaluated.
