DTI’s developers have extensive experience building, testing, delivering and maintaining integrated information applications systems (software solutions) to support modernization and evolving production environments. Our teams of professional developers complete all necessary technical design, programming, development, testing, scripting, configuring/customizing of application modules as required to develop and implement the design plans and specifications. They recommend modifications and performance enhancements to system software, hardware platforms, and support utilities. SMEs develop related support documentation for end-users, IT Service Desk, and all related O&M and system administration. DTI also conducts software services which include completing functional and system designs.

Design Software Services Experience

Our developers designed software services for 100 new and 25 existing software applications, using coding standards for Application Messaging and Directory Access Services (AMDAS), EDAS, SSO, and EAIB software applications. Developed system and application source code (software module and software unit) and executable code in accordance with Treasury coding standard and including internal and external interfaces; unit and software (string) integration into the ACA PMO, PPI-GOV and EOPS targeted development environment. Conducted Software Development Testing within the development environment. Identified, tracked, reported and resolved software defects and conducted regression testing as required. Created and updated operating documentation and software design documentation to reflect changes resulting from testing. Ensured format and/or configure source code was compliant with Rational ClearCase system. Used Java, J2EE, AJAC, JBOSS, ASP.NET, XML, XACML, and Perl programming language and associated compilers to support software coding and generation of executable code.

Database Services Experience

For 40 new and 30 existing database applications, deployed database applications such as CDS, SAAS, and ES to PPI-GOV and EOPS environment. Database services included the following; created initial performance parameters and object allocation; access control mechanisms (e.g., scripts implementing roles, privileges, and permissions); database interfaces, input/output data feeds, and data preparation (e.g., data cleansing and data conversion); data Extraction, Transformation and Load (ETL); and operational scripts and code supporting archival and backup. Used Microsoft Entity Framework Designer, First SQL+, Database Design Pattern Framework database tools to support database development effort, Prepared Updated Logical and Physical Designs and Data Models, Physical Database Schema, Operational Scripts and Archival and Backup. Our DBAs perform the following functions listed below:

System Integration Services Experience

DTI has extensive experience managing large, complex systems and integrated applications that have evolved over many years and require significant efforts to both operate and modernize simultaneously. A key factor in sustaining a high level of growth while continuing to meet mission needs is the ability to integrate new technologies into an existing facility without impacting operational requirements and continuity of services. Team DTI has demonstrated experience implementing change on multiple projects, while doing no harm to the continuity of services. DTI provided system development integration on 100+ software applications and 70 database designs to ensure proper integration and interoperability using the system integration tools (eTXIntegrator, ActiveEdge and Adeptia Integration Suite). DTI performed the key activities, including a review of interface descriptions for completeness, the readiness of system components for integration, assembled product components; evaluated assembled product components; and packaged and delivered product or product components to support further design and testing activities. DTI supported the development of the following work products: Product Integration Strategy; System Development Integration Plan and Procedures. For example, DTI’s test team was responsible for prototyping, engineering, piloting, and deploying SSO application and used the standardized build promotion process to progressively introduce the application into the test environment ahead of production schedule while ensuring no anomalies occurred during the soak in period.
