Single store – single local database server to multi store multi location – codeproject

Company is in retailing and have 2 retail stores in in same city. Moto g data recovery software Both stores always stay busy and customers are always in waiting at the counter. Data recovery windows 10 Basically, it is desktop based CRM application which has lot of modules inside it apart from invoice/Receipt module, it has other modules like Delivery module, installation module, Service/Repair module, Account Receivable module and many other modules used by various back office departments of the company.

Database youtube Other resources/hardware such as Barcode Printer, Receipt Printer, and Barcode scanner are connected to the CRM on Desktop PC.

Till couple of weeks back, company had no issue using this desktop application and single MySQL server as all clients were connected via LAN or WLAN.

Now situation has changed, and new requirement has raised: Company has planned to open new stores at very far distance. H2 database console Such stores cannot be connected to current central database via LAN or WLAN. Database browser Each new branch would have around 20-30 clients, say “Branch Clients”

Also, there would be field executive who will be working from their laptop. Database help Say “Remote Clients”. Database vendors They will just have 3G internet connection on their laptop.

Not possible: Connection over the internet would be very slow for fetching such huge data. Database key Data is really huge For, e.g. Data recovery live cd if client opens “Customer Master”, then there would be more than 600,000 rows which takes lot of bandwidth and time to open over the internet. Data recovery clean room And there are many more such modules which loads lot of data.

Also, in case of losing internet connection, clients would not able to operate the application. Database view Customer waiting in line to make receipt would go crazy if they have to wait for long.

Thought 2: Install new MySQL server at branch store, all the desktop PCs then would be connected to that local branch server. Data recovery fort lauderdale And then that local branch server would be connected to central server via MySQL replication option.

Not possible: Since MySQL replication has limitation of only one way replication, we cannot implement this structure. Data recovery equipment tools Application requires to move data from central server to branch server and from Branch to Central in real-time. Data recovery lab Also, MySQL replication engineering has limitation to replicate only with one server only. Data recovery online In that case, we cannot replicate with multiple branch stores. Database union There is an option of cluster server, but company cannot afford licensing cost.

Not possible: I think looking at current requirement (fast access), environment (retail store-pos) and hardware (printers, scanners) connected to client – it is not advisable to have web application and cloud database server. Data recovery houston Also in the event of no internet, entire store would go down.

Thought 4: Somebody suggested me that I should move from MySQL server to MSSQL and keep desktop application as it is. 7m database soccer basketball MSSQL has capability to sync with multiple servers in real-time over the internet. Create database link It has no limitation like MySQL’s one way replication and only one replication connection.

I guess, to make faster and constant database connection, installing local branch server is highly required. Database form But I don’t know how those different branch servers could be connected to central server.

• What is the best way to resolve above issues in given condition and successfully fulfill the company’s requirement? Faster and constant connection to database server. Data recovery process And also real-time updates between all branches and central server. Database training If internet connection is down, then delay in real-time update is acceptable but clients should not be affected from work.

• Would migration from MySQL to MSSQL resolve the issue? Because data migration is not issue as there are many tools available which converts the database from one platform to other. Data recovery hardware But issue is – application is very huge having hundreds of query written for MySQL. Best database software I guess I have to change those all queries also, because queries are not same for MySQL and MSSQL. Database gui Do I have to change all the queries or just the few percentage queries? Or if there is any tool available which convert queries from MySQL to MSSQL query.
