+# MediaWallah MEDIAWALLAH_ENRICHMENT_APP App
+https://app.snowflake.com/marketplace/listing/GZSOZ5Q3W8J/mediawallah-inc-mediawallah-enrichment-app
+
+## Version
+V1
+
+## Description
+
+**Note: The Enrichment Application is currently only available on `AWS US-EAST-1` MediaWallah is working to make this available in other regions**
+MediaWallah's Enrichment Data Marketplace listing holds Two Applications. **Matchtest** and **Enrichment**.  
+**Matchtest** - Allows users to quickly test overlap between consumer's own data with various MediaWallah dataverse without exposure. Providing informed insights on if dataset is worth enrichment.  
+**Enrichment** - Returns consumer's data linked to MediaWallah's dataverse. Allowing consumers to check for data quality and usability.  
+Users of the free Enrichment application has a limited version of the Enrichment Application; only returning a percentage of the total for a limited time window.  
+Please Contact MediaWallah if additional time or trial runs are needed.  
+Enrichment results are returned in four tables

+
+## Prerequisites
+* The provider must accept the Snowflake Marketplace Provider Terms of Service.
+* The consumer must accept the Snowflake Marketplace Consumer Terms of Service.
+* The consumer must be able to operate ACCOUNTADMIN, SECURITYADMIN roles.
+
+## Provider vs. Consumer
+* The Native Apps Framework term “provider” refers to MediaWallah, as the app’s owner.
+* The Native Apps Framework term “consumer” refers to the provider’s clients that install the app.
+
+## Disclaimer
+Any screenshots and code blocks included in this guide are examples. Please refer to the text in the steps below when installing this app.
+
+## Setup
+### Step 01: Account Setup (Post-Install)
+Create objects and “helper” stored procedures.  
+The following scripts help streamline the log sharing process and app usage considerably, and can be executed by the consumer before or after the app installation.  
+Executing the scripts will create everything the consumer needs to use the app, including roles and warehouses.  
+**NOTE:** The ACCOUNTADMIN and SECURITYADMIN roles are required create the APP_ADMIN_ROLE, which is granted privileges to complete the pre-install setup:  
+* IMPORT SHARE
+* CREATE SHARE
+* CREATE DATABASE
+* CREATE WAREHOUSE
+* CREATE APPLICATION
+

+-------------------------------------------------------------------------------
+-- 06_grant_application_role.sql
+-- This grants the application role to a specific user of the application if one was not granted on installation
+-------------------------------------------------------------------------------
+USE ROLE ACCOUNTADMIN;
+SHOW APPLICATIONS;
+
+SET APP_OWNER = (SELECT "owner" FROM TABLE(RESULT_SCAN(LAST_QUERY_ID())) WHERE UPPER("name") = 'MEDIAWALLAH_ENRICHMENT_APP');
+
+USE ROLE IDENTIFIER($APP_OWNER);
+
+GRANT APPLICATION ROLE MEDIAWALLAH_ENRICHMENT_APP.APP_ROLE TO ROLE C_MWEN_APP_ADMIN;
+```
+
+
+### Step 02: Verify Installation
+Once the app is installed, the consumer should verify installation by querying the METADATA_C_V view. If the table’s headers are visible then the consumer can continue to Step 04: Onboarding.
+**Example:**
+```sql
+------------------------ Step 02: Verify Installation ------------------------
+USE ROLE C_MWEN_APP_ADMIN;
+USE WAREHOUSE C_MWEN_APP_WH;
+SELECT * FROM MEDIAWALLAH_ENRICHMENT_APP.UTIL_APP.METADATA_C_V;
+-- NOTE: should see metadata table headers
+```
+
+
+### Step 03: Onboarding
+To be onboarded the consumer must send their CURRENT_ORGANIZATION_NAME, CURRENT_ACCOUNT, and CURRENT_ACCOUNT_NAME to operations@mediawallah.com; with the subject line “Native App Onboarding Request: MediaWallah MEDIAWALLAH_ENRICHMENT_APP App".  
+These details can be found using the following queries:
+
+```sql
+------------------------ Step 03.a: Onboarding ------------------------
+SELECT CURRENT_ORGANIZATION_NAME();
+SELECT CURRENT_ACCOUNT();
+SELECT CURRENT_ACCOUNT_NAME();
+```
+Onboarding typically will occur on the day of the request, however, please allow up to 2 business days.  
+Once onboarded, the consumer should see metadata entries when querying the METADATA_C_V view.  
+**Example:**
+```sql
+------------------------ Step 03.b: Onboarding ------------------------
+USE ROLE C_MWEN_APP_ADMIN;
+USE WAREHOUSE C_MWEN_APP_WH;
+SELECT * FROM MEDIAWALLAH_ENRICHMENT_APP.UTIL_APP.METADATA_C_V;
+-- NOTE: should see metadata table with entries
+```
+
+
+### Step 04: Log/Metric Sharing
+After being successfully Onboarded, the consumer uses the **C_MWEN_APP_ADMIN** role to call the CREATE_LOG_SHARE helper stored procedure. This procedure creates the necessary database, tables, and share to store the logs and metrics tables and enable MediaWallah to access them.
+**Example:**
+```sql
+------------------------ Step 04: Log/Metric Sharing ------------------------
+USE ROLE C_MWEN_APP_ADMIN;
+USE WAREHOUSE C_MWEN_APP_WH;
+CALL C_MWEN_HELPER_DB.PRIVATE.CREATE_LOG_SHARE(
+  'MEDIAWALLAH_ENRICHMENT_APP'
+ ,'MWEN'
+ ,'MEDIAWALLAH'
+);
+```
+
+
+### Step 05: Enablement
+The consumer will be automatically enabled once the log share is verified by the application (this process takes about two minutes). Query the METADATA_C_V table to check for successful enablement:
+**Example:**
+```sql
+------------------------ Step 05: Enablement ------------------------
+SELECT *
+FROM MEDIAWALLAH_ENRICHMENT_APP.UTIL_APP.METADATA_C_V
+WHERE KEY = 'enabled'
+;
+-- NOTE: should see metadata key/value pairs, along with enabled = 'Y'
+```
+
+## Usage
+### Granting Application Access to the Consumer's Dataset(s)
+The application will need access to the consumer's dataset; **Either directly to the table or a view of the table.**
+
+
+**Example:** Granting access to the a consumer's dataset `[CONSUMER_DB].[CONSUMER_SCH].[CONSUMER_TBL]` owned by `SYSADMIN` role to the **C_MWEN\_APP_ADMIN** role.  
+(Replace placeholders accordingly)
+```sql
+-- Below is the code with all the database, schema, and table names that need to be replaced in brackets
+-- use the role that has ownership of the source data table
+USE ROLE SYSADMIN;
+-- grant privileges to source data
+GRANT USAGE ON DATABASE [CONSUMER_DB] TO ROLE C_MWEN_APP_ADMIN;
+GRANT USAGE ON SCHEMA [CONSUMER_DB].[CONSUMER_SCH] TO ROLE C_MWEN_APP_ADMIN;
+GRANT SELECT ON TABLE [CONSUMER_DB].[CONSUMER_SCH].[CONSUMER_TBL] TO ROLE C_MWEN_APP_ADMIN;
+-- Now the Table [CONSUMER_DB].[CONSUMER_SCH].[CONSUMER_TBL] can be used by the Application!
+
+-- Creating a view of source dataset table in C_MWEN_HELPER_DB.SOURCE schema
+USE ROLE C_MWEN_APP_ADMIN;
+CREATE OR REPLACE VIEW C_MWEN_HELPER_DB.SOURCE.[CONSUMER_VIEW] AS
+  SELECT * FROM [CONSUMER_DB].[CONSUMER_SCH].[CONSUMER_TBL];
+```
+
+### Generating Requests
+Once enabled, the consumer can call the GENERATE_REQUEST helper stored procedure to use any of the consumer’s allowed stored procs. Data will be generated into the MEDIAWALLAH_ENRICHMENT_APP.RESULTS_APP schema. View [Results Guide](https://nativeapps.mediawallah.com/MEDIAWALLAH_ENRICHMENT_APP/MWEN%20-%20Results%20Guide.pdf) for a detailed explanation of the generated data.
+Optimal warehouse sizing will depend on consumer input dateset dimensions. MediaWallah maintains an average run times based on historical runs in a Warehouse Sizing Doc, ask for details.
+**For a detailed explanation of the parameters used in GENERATE_REQUEST, see next page**  
+
+**Matchtest Example:**
+```sql
+------------------------ Generating Request: Matchtest Example ------------------------

+#### Using ARID
+An ARID (App Resolution Identifier) is the primary key generated per run of the application, used to join the original data with enriched digital data, enriched offline data and/or enriched audience segment data.
+**Example joining Data**
+```sql
+SELECT c.*, e.ID_VALUE, e.ID_TYPE
+FROM MEDIAWALLAH_ENRICHMENT_APP.RESULTS_APP.[RESULTS_TABLE_NAME]_ENRICHMENT c
+JOIN MEDIAWALLAH_ENRICHMENT_APP.RESULTS_APP.[RESULTS_TABLE_NAME]_ENRICHMENT e
+ON (
+    c.ARID = e.ARID
+AND e.ID_TYPE = 'MD5_HASH'
+)
+;
+```
+
+**Example joining audience with taxonomy**
+```sql
+SELECT a.ARID, t.SEGMENT, t.SEGMENT_VALUE, a.ID_VALUE, a.ID_SUMMARY_TYPE, a.ID_TYPE, a.TIER, a.MATCH_KEY
+FROM (
+    SELECT e.ARID, s1.VALUE::varchar AS ID_VALUE, e.ID_SUMMARY_TYPE, e.ID_TYPE, e.TIER, e.MATCH_KEY
+    FROM MEDIAWALLAH_ENRICHMENT_APP.RESULTS_APP.[RESULTS_TABLE_NAME]_AUDIENCE_ENRICHMENT e

+
+## Uninstall (Optional)
+In the event the consumer wishes to uninstall the app, the consumer can use the **C_MWEN_APP_ADMIN** role to call the UNINSTALL helper stored procedure. This procedure will drop the application database, the logs share, and the shared logs database. The Application Share (which includes the results and logs tables) will be permanently removed from the consumer’s Snowflake instance.  
+**Note**: It is important to note any data generated by the application stored in MEDIAWALLAH_ENRICHMENT_APP.RESULTS_APP will be lost. Please export results accordingly.  
+**Example:**
+```sql
+------------------------ UNINSTALL ------------------------
+USE ROLE ACCOUNTADMIN;
+SHOW APPLICATIONS;
+
+SET APP_OWNER = (SELECT "owner" FROM TABLE(RESULT_SCAN(LAST_QUERY_ID())) WHERE UPPER("name") = 'MEDIAWALLAH_ENRICHMENT_APP');
+
+USE ROLE IDENTIFIER($APP_OWNER);
+CALL C_MWEN_HELPER_DB.PRIVATE.UNINSTALL('MEDIAWALLAH_ENRICHMENT_APP');
+```
+
+Example:
+* To remove the C_MWEN_HELPER_DB:
+```sql
+DROP DATABASE C_MWEN_HELPER_DB;
+```
+* To remove the C_MWEN_APP_WH:
+```sql
+DROP WAREHOUSE C_MWEN_APP_WH;
+```
+* To remove the C_MWEN_APP_ADMIN:
+```sql
+USE ROLE ACCOUNTADMIN;
+DROP ROLE C_MWEN_APP_ADMIN;
+```
+
+## Upgrade (Optional)
+As new versions and patches are relased. To Upgrade use the following commands.
+```sql
+USE ROLE ACCOUNTADMIN;
+ALTER APPLICATION MEDIAWALLAH_ENRICHMENT_APP UPGRADE;
+```
+
+## Re-Enablement
+Consumer usage of the application is disabled when either of the following happens:
+1. MediaWallah loses access to the consumer log share (through either removing MediaWallah from the share or dropping the share altogether.
+2. The consumer purposely tampers with the logs shared to MediaWallah  
+  
+The consumer can re-enable themselves depending on the cases mentioned above:
+1. When MediaWallah loses access to the log share, if the log share exists in the consumer account, the consumer can simply add MediaWallah back to the share.
+  * For example:
+  ```sql
+  ALTER SHARE MWEN_[CONSUMER NAME]_APP_SHARE
+  ADD ACCOUNTS=MEDIAWALLAH;
+  ```
+If the log share no longer exists, the share can be re-created by calling the CREATE_LOG_SHARE helper stored procedure.
+  * For example:
+  ```sql
+  CALL C_MWEN_HELPER_DB.PRIVATE.CREATE_LOG_SHARE(
+    'MEDIAWALLAH_ENRICHMENT_APP'
+   ,'MEDIAWALLAH'
+  );
+  ```
+2. However, when the consumer tampers with the logs, the consumer is disabled immediately and cannot re-enable themselves. MediaWallah decides if that the consumer can use the application again, and re-enables them. Once MediaWallah allows re-enablement, the consumer can re-share the logs, get enabled, and continue to use the application.
