The Challenges of Migrating Application Systems
Today, business applications are as critical to an organization as people or capital. Inflexible mission-critical applications monopolize resources, starving other parts of business.
Properly aligned with strategic business goals, flexible applications can help transform a company.
Companies looking for speed and flexibility from their legacy systems find that modernizing their legacy system into a flexible set of services allows the right information access for each customer.
A services approach allows the user interface layer to be quickly remodeled to changing business needs.
This solution allows an application to be modernized by reorganizing the core technology but will continue to run the newly reorganized services on your current hardware in the same language.
Traditional vs. TMG SOA Projects
| Traditional Manual SOA Project | TMG Remodel for SOA Project |
| Large teams - difficult communication | Small team of Experts - streamlined communication - systems approach through automation. |
| Time consuming manual effort to find elements of system that relate to desired services. | DMS Modernization Technology brings automation to the effort of identifying source code that relates to each desired service. DMS Automated Analysis helps identify a list of potential services and identify the source code that relates to the services. |
| Manual reorganization of source code into services is a highly tedious and error prone task. | DMS rule-based automation is used to reorganize the source code elements and also to define interfaces to the services. |
| Maintenance to legacy system during project can significantly extend the SOA project or be left out. | TMG SOA projects will include all maintenance changes up to the last full service reorganization cycle. |
What we mean by "Remodel"
Remodeling is a term that we use to communicate the way that we use our automation to make consistent changes to a legacy system.
When you remodel a house you may decide to change one room, several rooms or an infrastructure element like heating/cooling, plumbing or electrical.
Similary, our technology allows our engineers to describe the abstract structure in the application that needs changed and then changes the system consistently the way that you want.
TMG's Services for SOA solution offering effectively converts your legacy application into a set of flexible services by:
- Identifying and separating the service from the client functionality.
- Identifying Internal Application APIs to be exposed.
- Sets of procedural code that comprises an API.
- Sets of database queries representing data to be exposed.
- Processing source code and identifying where the identified APIs are located and the dataflow to and from them.
- Synthesizing a SOA interface for the API.
- Remote procedure calls / Services for COBOL.
DMS Modernization Technology enables the separation of identified service functionality and source code related to client functionality. Through the use of generated control and data flow diagrams, the service oriented source code is combined and the same is done to the client code. These sets of source code are modified so that an "API" is created for the service functionality and the client functionality is adapted to this new "Service API". Once the API's are created, the service can be used to enhance business use of the service functionality.
The example above shows how legacy source code is modified into a client and service approach. Call The Mod Group, Inc. so we can give you a full presentation of our capabilities.
