The algorithms will be detailed up to the level of primary operands. Inputs and outputs of a standard MIS are established and according to the specifications of CCM were used to determine the types of entities, relationships and attributes of CDM.
Editpresentasi Ccm Seminar 2 Documents. For this purpose we take into account various criteria: In this case, you would specify the roles they play in the association, the roles that show mdc entity’s participation in association. Integrity of roles constraints refer to the roles played by an entity in various associations and have three forms: The importance of these documents is that it can reveal the stage reached in cardinalt development process and, in the same time, it can be determined the responsibilities especially when malfunction occurs.
The cardinality express the participation of the achievements of the entities to the associations. Cdm – Dissertation 2 Documents. After the analyzing of the information content of the input document it will set the attributes of the new system. The flow diagrams are graphical representations that reflect the links between actors.
An association exist only if the achievements of entities linked exist. These objectives have general and specific characteristics that depend on the legal and regulatory framework, endowment with computers and economic development requirements of the company These objectives can be grouped into the following categories: Latest News Is the media fueling global conflict? Detailing of financial flows is as follows: The arc using a numeric notation, which correspond to the sequence encoding processes and documents, as objects of the information flow.
The collection of an association is given by the participating entities. Th association Sign exists if there is an achievement of the entity Client and an achievement of the correspondent entity Contract only. System objectives require solving problems with synthetic character in a systematic manner using IT support.
The attributes used by MIS are of two types: Making CCM can be considered as an iterative process if the analyzed economic phenomenon is complex. It occur as static or dynamic constraints. Cardinality is minimal 0,1; 1,1 or maximal 0, n; 1, n.
Documents can be standardized or non-standardized. Actors can be internal or external actors actors belong to the internal or external structure of MIS.

Referential constraints implies the existence of association that is determined only by the existence of the achievements participating entities in the association. This method ensure the optimum among the set of input variables that need to be processed in order to achieve output variables and situations.
Grouping is done taking into account different criteria: The integrity constraints are rules that must be followed by the elements attributes, associations, entities and their inclusion in the early stages of design leads to a faster troubleshooting errors that mersie in running applications.
An association does not have an independent existence. But we must not exaggerate the creation of sets of input variables that will not be processed and will take up the system resources. Such documents may be accounting notes, internal memos or notices.
