To minimize production downtime and avoid legacy system migration issues, AQIES offers to use full-cycle database migration services. We apply our database development skills to effectuvely establish the target database and utilize data connectors, ETL tools and manual scripting for data migration. In such cases AQIES proposes the following database migration process:

  • Migration planning
  • Target database preparation
  • Migration testing/Simulation
  • Data migration
  • Data consistency and integrity verification

Data Connectors

Ifllexion is experienced in developing configurable one-way and bidirectional data connectors enabling data exchange, mapping and synchronization across various technology platforms, databases and business applications. Through our expertise we accomplish the following major objectives:

  • Extend software capabilities and add value by integrating with popular web services and SaaS products like Salesforce or Amazon Web Services.
  • Interconnect line-of-business applications to achieve straight through processing, avoid manual iterations and automate data verifications. The result is complete support of transparent and smooth business workflows and result driven Business Intelligence

Business Intelligence Databases

Building business intelligence solutions shifts our database development focus to the following areas:

  • Data mining
  • ETL execution
  • Embedding data quality management procedures
  • OLAP cubes development
  • KPIs calculation

A typical task for AQIES is to organize aggregated and consistent data marts and BI-ready infrastructure, visualize their output effectively and make them accessible for decision-makers through a web interface.

Key Principles


AQIES puts emphasis on database security, protecting sensitive data and providing easy user access management. AQIES delivers:

  • Database roles and security schema planning
  • User authentication and authorization procedures
  • Secure database connections
  • Data encryption
  • Security standards compliance
  • Database audit and vulnerability assessment


We are experienced in building high-performance databases requiring highly productive architecture and topology, finely tuned indexing, queries and transactions, as well as special techniques for data clustering, caching, load balancing, etc. Such demanding databases are always needed for web applications that focus on online data processing and handle huge volumes of structured/unstructured data. Great examples are content distribution and news portals, payment gateways, web 2.0 solutions and social networks.

ETL and Data Quality Management

From a business perspective, a productive efficient databse is one that contains and manipulates well-structured, actual and consistent data. AQIES pays great attention to ETL process and data cleansing, normalization and mapping.
To accomplish these tasks, we utilize a number of open-source and proprietary data extraction and transformation tools, like:

  • Talend solutions
  • Microsoft SQL Server Integration Services
  • Oracle Warehouse Builder
  • Informatica
  • Oracle Data Integrator
  • Oracle Middleware
