Subject: LinkSOFT WEB API to handle data transmission between two LinkSOFT Databases instead of using "Linked Servers"
Summary:    

LinkSOFT API development to handle data transmission between two LinkSOFT Databases. This is required to eliminate the following issues:

  1. Replication uses Linked Servers. We have a lot better control via an API and can throttle and add size limits to handle bandwidth and traceability.
  2. Opening SQL server PORT 1433 on a LAN environment poses some risk. Some customers require replication over the internet and are opening SQL server port despite being advised to use a VPN.
  3. Some data for TNA needs to be sent from local installations to the cloud.

High-level design:

  1. Each transmission should be a closed-loop transmission. i.e. there should have a known origin and each batch must be tracked from Initiation, transmission to closure.
  2. Create a function that allocates a unique number to each transmission. The unique ID should be readable, suggest YYMMDD-HHMMSSS-{3 digit code}. Let's name this "Transmission ID", referenced as "TID", to denote a readable code user can use to track each transmission.
  3. This code should be referenced in the status of each transmission. e.g. In TNA, a file being transmitted should have Statuses: "Queued {TID}", "Transmitted {TID}" and at the receiving end, "Received {TID}", "Processed {TID}", "Closed {TID}"

Please perform the following tests on Compare Data

  1. Verify Masterfile
    1. Send/Receive Differences
    2. Verify again to confirm data has transmitted correctly
  2. Verify Transactions
    1. Send/Receive Differences
    2. Verify again to confirm data has transmitted correctly
  3. Review Error logs and API Queues
  4. Use Queue monitor to track packages

For Replication Testing, setup the environment as follows:

  1. One Standalone
  2. Two Branch
  3. HQ

Test data flow between all stations, monitor time taken and record results

Environment Details

  1. OS version:
  2. Application version: 12.50.07023GA
  3. Setup on:
    1. Server:LinkQA4
    2. Database: LinkSOFT-HQ, LinkSOFT-B1, and LINK SOFT-Standalone
