Cobol

Any time you name an element (a type, an attribute, and so on) you must also know the scope within which that name uniquely refers to that element. A Cobol variable name... 

Existing batch-mode systems Often, late-night COBOL batch jobs encode critical sets of business rules. Mary of these mles can be captured as time-dependent static invariants on the type model (the batch job cuts in to make sure that no objects will be in violation of these invariants, come sunrise) or as effect invariants, of the form Whenever this thing has changed, that other thing must be triggered. ... 

Components in Catalysis need not be built using object technology. The concept of a type model and operation spec can be applied equally to a Java, C++, COBOL, or assembler implementations—and therefore to legacy systems—thanks to refinement. 

Around 1965 the US government sponsored the introduction of COBOL (Common Business-Oriented Language) as a simple platform-independent language for database management.

The r stands for "reduced" and Ihe s for s ier-ceduced. The latter may seem to be somethHvg cf an exaggeration until one recals that the predonunani coordinalion chemistry of coboll is that of COdll), with less for Cotll). and very Male for other oxidalion states. 

Layer 1 Operational (legacy) systems layer. The basic layer consists of existing custom built business applications. These applications, mainly mainframe systems implemented in COBOL, realize the business functionality. To enable distributed and parallel access to applications, a transaction monitor ensures fault-tolerance, consistency, recovery, and performance balancing. 

Layer 2 Technical adapters layer. This layer is responsible to embed legacy systems into the new technical infrastructure. This is done by technical adapters. These components serve as proxies adapting the existing COBOL interfaces to the required new syntax. No kind of semantical homogenization is done on this level. A typical task of an adapter is, for example, the conversion of data types. Furthermore, adapters encapsulate physical distribution and the corresponding communication protocols. 

JAVA classes are then embedded into a corresponding JAVA-based framework for accessing COBOL-based mainframe applications via a transaction monitor. 

Using this tool chain, the required COM interfaces to existing COBOL applications are reahzed without any manual implementation effort. However, only data aspects are covered, as a COBOL copybook only describes a data structure. Functional aspects, such as a calculation based on some given data can not be handled this way yet. 

Methyl ohloride—CH,C1—50.5—is a colorless gas, slightly soluble in H,0, and having a sweetish taste and odor. It is obtained by distilling together H,SO sodium chloride and methyl achohol. It may be condensed to a Umiid which boils at —22 (—7 .6F,). It bums with a greenish fleune. Heated with potassium hydrate it is converted into methyl coboL...
