A Low-Cost In-House Tool for Data Integration and Migration

Source code on a computer screen

Data migration and integration are often the hidden cost in an enterprise transformation project. A large share of the implementation effort goes into connecting legacy systems, external platforms and modern applications, especially when heterogeneous data sources are involved.

At Emeis Technologies, we ran into this problem on our own projects, so we built a tool for it.

That tool is B2B, our in-house integration platform. Its job is to make enterprise data migration and integration faster and cheaper.

Why B2B?

A common and painful problem is consolidating data from multiple legacy and third-party systems into a centralized application or cloud platform.

B2B handles this by:

  • Supporting both homogeneous and heterogeneous data systems

  • Handling high-volume data reliably

  • Managing complex schema variations

  • Addressing security, scalability, and performance bottlenecks

Typical jobs include modernizing a legacy ERP, syncing CRM records and consolidating customer data from several sources. In each case B2B cuts cost, risk and manual effort.

Data migration flow: records from heterogeneous source systems pass through mapping rules and syntactic and semantic validation, become business objects, and are queued and saved into the target systems.Data integration toolFrom many sources to one clean targetSource systemsFiles, databases,folders and APIsTransformMapping rules,syntactic andsemanticvalidationBusinessobjectsClean, validatedrecordsSave queueQueued for insertor updateTarget systemsYour newapplication

How It Works

B2B works in two modes:

Push Mode (Real-Time)

  • Synchronous communication with destination endpoints

  • Delivers immediate feedback from the integrated systems

  • Ideal for transactional systems that need instant data updates

  • Also supports distribution to multiple destinations in real time without affecting the performance of the primary application

Pull Mode (Scheduled)

  • Used for periodic syncs and migrations

  • Suited to bulk data loads and nightly jobs

  • Keeps data in sync across systems on a defined schedule

Both modes use the same mapping engine, which defines how source data is transformed into the target format.

Source & Destination Flexibility

B2B supports a wide variety of systems and formats:

  • Excel/CSV/JSON (via FTP, SFTP, shared folders)

  • Relational Databases

  • APIs (REST/GraphQL)

  • CRM Platforms

  • Custom Plug-ins for unique business logic

 

Smart Mapping Engine

You configure mappings in a simple UI. Main features:

  • Source-to-destination column binding

  • Data type and length management

  • Default value handling for nulls

  • Lookup and relationship mapping

  • Field-level validation (regex, custom rules)

  • Plug-and-play custom logic for advanced transformations

Automation, Monitoring, and Reporting

Background Services

Scheduled services run in the background, syncing data hourly, nightly or in real time, as configured.

Notifications

Automated emails are sent for job success, failure, or warnings. Distribution lists are managed at the job level.

Logs & Reconciliation Reports

  • Track success, warning, and error counts for each sync

  • Detailed logs available via UI for debugging and monitoring

  • Reconciliation reports can be sent as email attachments for audit compliance

The Bottom Line: Affordable + Efficient

B2B is built to keep costs low without giving up capability or scale. Our clients, from growing businesses to enterprises with complex data estates, use it to save time, lower integration risk and go live sooner.

Frequently asked questions

What is heterogeneous data migration?

Moving data between systems that store it differently, for example from spreadsheets, legacy databases and APIs into a new application, with the data mapped and transformed along the way.

Why use an in-house integration tool instead of an ETL suite?

Enterprise ETL suites are powerful but expensive and slow to set up. A focused in-house tool covers the common source and destination types, with a smart mapping engine, at a fraction of the cost.

Can the same tool keep systems in sync after migration?

Yes. Once mappings are defined, the tool can run on a schedule to integrate data between systems, not just move it once.
