== What is Enterprise Data Replication (EDR)? ==
'''Enterprise Data Replication''' is a technology that allows organizations to store the same data in multiple locations, providing better data availability and accessibility.

Enterprise Data Replication helps reduce costs associated with bandwidth and maintenance by allowing users to access the replica closest to them. It also provides an easy way to monitor and configure tasks across hundreds or thousands of endpoints. Additionally, it triggers a robust disaster recovery and backup management system that ensures data remains safe in case of any unforeseen events or disasters. The end result is an effective Data Analytics and Business Intelligence setup that can help companies gain insights into their operations faster than before possible with Enterprise Data Replication technology.


== Replication Processes used in Enterprise Data Replication ==
EDR uses a variety of replication processes to make enterprise data available across different locations. These include:
#One-way replication: This is used to ensure that the latest version of data is available at all times, regardless of which direction it is flowing in.
#Bi-directional or Two-way replication: This type of replication provides high availability by ensuring that both ends have access to the same up-to-date versions of data at all times, allowing users on either end to update their databases simultaneously without risking data loss or corruption due to lag time between updates.
#Global propagation: Global propagation allows for efficient synchronization across multiple nodes located around the world, reducing latency issues associated with traditional methods such as file transfers over slow internet connections between remote sites or countries with slower internet speeds than those found in more developed nations where most businesses operate today (e .g . , US).


== How to Set Up an EDR System? ==
'''Step 1: Consolidate data'''<br />
*Design and implement a data integration process to feed a datastore with complete, enriched data.
*Restructure the data, perform a reconciliation process, cleanse it thoroughly, and aggregate it for further enrichment.
*Identify all sources of data that need to be consolidated and create mapping rules for each source pair to ensure consistency across all datasets being integrated into one master dataset.
*Create automated processes to continuously monitor changes in both source datasets and update the master dataset accordingly whenever necessary (e..g., when new customer records are added).
*Ensure that any discrepancies between source datasets are identified quickly and resolved quickly as well (e..g., missing/incorrect information).
'''Step 2: Use data propagation'''<br />
*Identify the source and target datastores: Data propagation can be used to copy data from one location to another. In an EDR system, the source datastore will contain all of the data that needs to be replicated and the target datastores will receive this data.
*Set up event-driven synchronization: Data propagation is event-driven, meaning that it can be done synchronously or asynchronously depending on your needs. You should set up a system where changes in one location trigger processing in another location automatically, without manual intervention from users or administrators.
*Configure two-way data exchange: Most synchronous data propagation supports two-way data exchange between the source and target applications/datastores so that both sides have access to updated information at any time during the process..
'''Step 3: Use data federation'''<br />
*Identify the data sources that need to be consolidated. These could be databases, applications or other sources of data.
*Establish a virtual database to store all of the aggregated data from different sources. This will serve as the single point of access for all of your data needs.
*Use enterprise information integration (EII) technology to create a common data model for heterogeneous data from different systems and provide a unified view of that data across applications and users alike.
*Use tools such as query optimization, materialization, parallel processing and caching to improve performance when accessing this large amount of data from multiple systems in real-time through one portal or application endpoint (e.g., web app).
'''Step 4: Use data warehousing'''<br />
*Data warehousing can help with the setup of an EDR system by providing a centralized Data Repository for data from multiple departments, sources, and applications. This provides access to critical information that captures a larger view of the entire business and helps to reduce challenges associated with working with data silos. Additionally, it enables departments to make better decisions based on insights gained from analyzing this consolidated data set.<br />
'''Step 5: Use EDR platforms''' 
*Identify the requirements for the EDR system, such as network connectivity and message types.
*Select an EDR platform such as RJ or Seesam that meets your requirements and has a flexible command and control interface for web browser or green-screen administration and operations.
*Configure the platform to suit your needs, including setting up connections between nodes, defining message types, and configuring routing rules if needed.
*Set up automated processes to manage messages across multiple nodes according to defined rules (for example: sending messages across multiple nodes based on certain criteria).
'''Step 6: Configure replication rules'''
*Create a replication rule for each endpoint that needs to be monitored.
*Enter the name, address, and other relevant information about each endpoint into the rule configuration page.
*Set up notifications for when the rule is triggered and actions need to be taken in response (e.g., send an alert email).
*Configure automatic recovery actions if any of the endpoints become unavailable (e.g., failover).
*Monitor the progress of tasks from within one centralized console or through alerts sent out by your EDR system.
'''Step 7: Set up an actionable monitoring strategy'''
*Identify the key performance indicators (KPIs) that you want to monitor. These should be relevant to your organization's goals and objectives.
*Create a list of all endpoints that need to be monitored, including servers, workstations, mobile devices, etc..
*Configure the EDR system to monitor each endpoint and set up replication tasks if necessary for faster data collection and analysis purposes.
*Monitor the data collected from each endpoint regularly in order to identify any issues or trends that may impact productivity or business operations negatively down the line.


== EDR Replication Tools ==
EDR uses a variety of replication tools to meet the needs of different scenarios. These include:
*Snap EDR: Provides additional functionality over Snap EDR Express, allowing the ability to replicate data from one system to another, distribute data from one system to multiple systems, and aggregate data from multiple systems to a single system. It can be used for data protection between systems, data distribution, data consolidation, and disaster recovery.
*Replication Engine: The core component of EDR that provides high-speed database replication and propagation capabilities across potentially many nodes in global deployments.
*Recovery Manager: A web-based tool used for managing snapshots taken during offsite backup/recovery processes; it also provides visibility into current replicas across all nodes in a deployment network topology map


== Benefits of Enterprise Data Replication ==
*Improved data accessibility: Enterprise data replication enables IT teams to quickly centralize all of the data across their entire organization. It allows them to make any data available at any place, at any time. This helps improve data accessibility as it eliminates the need for different tools for different sources and targets, making it easier for IT teams to access and manage all of their organization's information in one place.
*Improved data consistency: Enterprise data replication helps to improve data consistency by providing a centralized platform for all of the organization's data. It allows for a reconciliation process to take place, which ensures that all of the disparate pieces of information are brought together in one place and structured correctly. Additionally, it provides an opportunity for cleansing and aggregation steps to be taken to further enrich the data. By consolidating all of an organization's data into one datastore, Enterprise Data Replication enables faster access and easier understanding of complex datasets. This leads to more accurate insights that can drive actionable decisions while ensuring consistency across all datasets.
*Increased recovery time objective: Enterprise data replication can help to increase the recovery time objective (RTO) by ensuring that critical data is continuously replicated in real-time. This ensures that businesses have fast and reliable access to their data, even in the event of a system outage or natural disaster. It also helps to minimize the impact of any potential data loss due to system failures or other unforeseen events. Additionally, continuous data protection enables automated journaling of data changes for faster restoration times and increased assurance.
*Increased data availability: Enterprise data replication provides a way to store the same data in multiple locations. This helps to ensure the high availability of the data, as it can be accessed from different locations if one of them fails. By having access to multiple copies of the same data, organizations are able to reduce downtime and increase speediness when accessing information. Additionally, they can also use this technology to scale up their systems without sacrificing robustness or security.
*Reduced system failures: Enterprise data replication provides a way to protect data integrity with minimal downtime when changing or upgrading IT systems. It allows businesses to migrate data between systems without losing any of its original properties. This helps reduce system failures due to downtime and ensures that businesses can continue operating without any disruptions in service.
*Enhanced business continuity: Enterprise data replication enhances business continuity by ensuring that businesses have a backup of their data at all times. This ensures that businesses can quickly and effectively recover from any type of disaster, such as natural disasters, system failures, or cyber-attacks. By having a complete data restore capability, businesses can quickly recover any lost or deleted data and continue operating without any interruptions in service or loss of customer information. Furthermore, enterprise data replication can be used to replicate critical business systems across multiple locations to ensure high availability in the event one location experiences downtime due to a disaster or other event.
*Improved data flow and integration: Enterprise data replication improves data flow and integration by providing fast and efficient data movement. It offers hyper-threaded connectors that can move large volumes of data quickly, as well as fully automated warehouses that eliminate the need for coding, mapping, and maintenance. This ensures that the data team can save time and resources while focusing on insights. Additionally, advanced auto-discovery for adds and changes keeps the datastore fresh with fields and objects automatically added. This helps ensure complete, enriched data is being fed into the datastore without any manual intervention required from the team.
*Increased data scalability: Enterprise data replication allows users to store as much data as they need in its raw form and send it to the target quickly. No specialized infrastructure for transformation processes is necessary before sending it to its destination. This ensures that users can handle larger volumes of data without sacrificing speed or efficiency. Additionally, it reduces the need for specialized infrastructure and resources needed for transformation processes, making it highly scalable.
*Improved data performance: Enterprise data replication offers a fast, efficient way to move large amounts of data quickly. It reduces the time it takes for data to reach its destination and ensures that all copies are up-to-date. By using enterprise data replication, organizations can reduce the risk of slow response times and ensure their data is synchronized across all locations. This helps improve overall performance while also reducing maintenance costs associated with manual updates.
*Cost savings: Enterprise data replication can help to save money by offloading the transformation of raw data to usable data from the target datastore. This process can become a bottleneck in cloud computing, as there is no added benefit such as reduced target server loads. By using enterprise data replication, businesses can reduce costs associated with hiring additional IT personnel or purchasing additional hardware and software licenses. Additionally, they can avoid potential downtime caused by slow or inefficient data transfer between systems.

**Configure the appropriate settings for each system integration protocol and format in the Qlik Replicate platform settings page.
**Test each system integration individually to make sure it is working correctly before moving on to testing them all together in a live scenario.
*Create a data governance plan for replication: Creating a data governance plan for replication can help to ensure that the process is efficient and secure. It helps to define who has access to what data and how it should be handled. By creating a data governance plan for replication, organizations can reduce the risk of unauthorized access or accidental loss of data. They also have more control over which datasets are being replicated and can track progress more effectively. Furthermore, having clear rules in place ensures that there is less confusion about how long certain datasets should be kept or if any changes need to be made. This helps with compliance requirements as well as reducing costs associated with managing large volumes of data over time.
