Due to the nature of our project recovery and time sensitive software work, we do not publish the usual long list of names that are on most consulting companies web sites. We keep our clients and their projects confidential. Listed below are business sectors with the services provided to them by Collinear Systems. If after a review of our services you would like a confidential discussion with some of our current clients, please call or email us to arrange that discussion so that you may verify our quality and timeliness of work.

Fighter Aircraft Field Data Collection and Analysis - A local major defense contractor was using a legacy field data collection and analysis software suite developed in Fortran, and wanted to upgrade to contemporary middleware and database technology.

They initially contracted with Collinear to perform a study and develop a set of recommendations for modernizing the system. Collinear first analyzed their data requirements, and recommended an improved relational database schema to replace their legacy flat-file system. We then focused on a Java-centric middleware approach, and conducted performance benchmarks using Java variants of their legacy applications. The final result showed how a Java middleware system could support their system upgrade, and still accommodate any legacy components that could not be ported.

The second engagement on this project was to mentor and assist with implementation of the first release of the system. Collinear's first assignment was to port a problematic C++ data decompression application to Java, and prove that Java was suitable for I/O intensive computing. Our final delivery, developed in just five weeks, performed faster and more reliably than the C++ application that had been under development for two years.

Data Center Systems Administration - A local natural resources management corporation required staff augmentation to perform system upgrades. The original environment consisted of several HP K Class machines running HP-UX 10.20 and HP-UX 11.00. These machines were migrated to HP rp5470's and rp7400's all running HP-UX 11.00.

The software environment in this data center consisted of many HP OpenView products, various compilers and runtimes, and Oracle products. In addition to preparing standard disaster recovery and back-out strategies, some software migrations had to be staged in a lab environment subject to functionality verification.

Over time this assistance with system upgrades expanded into other areas. Systems security issues were addressed with lab evaluations of systems security auditing software where the environment was similar to that in production and development. Password cracking and Unix file permission evaluation were also done.

Automated systems performance reporting was configured as well. Utilizing Seagate Crystal Reports and HP OpenView Reporter, these reports automatically generate and send their output to a central repository in html format. The information reported is compiled from HP OpenView sources and reporting tools from other vendors. This information is made available to the intranet via a web server, providing technical and non-technical personnel an insight as to how corporate resources are being utilized.

Intranet Application and Database Upgrade - A customer utilizing enterprise intranet applications requested that we upgrade their current applications to the latest java version and migrate to an Oracle database. This new infrastructure would also be required to meet the needs of an additional project. This required additional scalability and flexibility from the application as well as the database.

Collinear consultants analyzed the application and the existing database. The final recommendation and implementation was an application server upgrade and an additional Sun Solaris 8 machine configured as an Oracle database server. A combination of Collinear software, database and system engineers were used to make a successful transition.

Simulation and Graphics Engineering - A local simulation and visualization company needed additional resources quickly to design and implement new enhancements into a flight simulator used by a large defense contractor. Collinear consultants were able to implement the new changes on time and budget and are now on a long-term contract to support the ongoing upgrades to this simulator.
