Persistence Layer




To increase application maintainability and workflow transparency we separate data tier from business logic and keep data access and manipulation at the persistence layer — through object-relational mapping with ADO .NET Entity Framework or NHibernate and general-purpose query facilities provided by .NET LINQ.

We are also capable of dealing with solutions which require alignment with the rich capabilities native to Microsoft SQL Server — namely, working with stored procedures, functions and triggers, thus executing, at least partially, business logic at the database level.

Database Management Systems

Opus Software widely utilizes Microsoft SQL Server as the primary DBMS which makes .NET application development smooth and cost-effective.

At the same time applications may operate in a heterogeneous environment with multiple database technologies involved. Opus Software is skilled in a variety of database engines which allows using alternative DBMS’s like MySQL or Derby with .NET solutions.


It is vital for complex applications to support automated data exchange and have versatile integration capabilities. Opus Software provides them through competence in WCF and in-depth knowledge of ODATA, .NET Remoting, WSDL, UDDI, XML / XML Schema and HTTP.

Business Logic Layer



Business-driven Development Approach

Whatever the application type and solution domain, your business should be at its core. We use formal approaches for describing and documenting business process (BOM, BPMN and UML notations), thus mitigating vision mismatch risks and laying foundation for smart project planning and resource management.

Workflow-oriented Application Design

When developing web applications that support sophisticated business processes Opus Software concentrates on making configuration, execution and improvement of application workflows easy and understandable for users and administrators. We possess considerable expertise in WF and TPL, which helps us in creating highly manageable, productive and user friendly applications.

Application Life Cycle, Extensibility and Maintainability

When designing a solution we always keep in mind that its life cycle management and functionality extension should be cost-effective.
