In these dependency relationships with the category Command taken as the origin, the categories S1, S2 stock type, respectively Commercial Client and Customer Park as well as Category C type coding Commercial Catalog, are target groups.

The meaning depends on category types and a repository of reference data containing the relations. From the principle described above, the definition of categories becomes one shown in Figure 3: The deposit reference data related to the category F1 Command being the front office software package, due to the dependency relations guidance as shown in Figure 6, the deposit reference data related to the category C1 Commercial Catalog is that the software package front office.
The invention advantageously proposes to use a UML possibility for achieving homogeneous groupings of data. Kind code of ref document: An entity is a representation of a material or immaterial element having a role in the system that is to be described. According to the principles governing the orientation of dependence relations seen above, the meaning of these relations originates category F1 and as a target categories respectively S1, S2 and C1. The steps of the localization algorithm of locating the reference data deposit associated with a category is to actually designate the responsibility of what application is reference data related to search.
A method of reference data modeling an information system, characterized in that it is based on a UML modeling reference data of the information system listed in the application data fields of the information system, data referential information system being defined by a specialized concept inheriting characteristics of a generic concept, said method comprising the steps of: A type of coding category C1: Once this grouping categories by typing done, an essential feature of the invention is to bring coherence to the groupings of generic concepts in the same category with the data fields of IS applications.
Coding for each category type C1 at least one target original dependency relationship that category of type stock S1repeat the following steps of: According to the principles governing the orientation of dependence relations seen above, the direction of this relationship originates category F2 and S3 as the target categories. This second aspect of the invention is described with reference to Figure 6 illustrating a category diagram relating to an IF consists of a box office software, more commonly known software package “front office” according to English terminology, and a billing software package that implements respectively ordering and invoicing flows.
For example, if one takes in the context of a company can define a generic command line entitled concept. According to the principles governing the orientation of dependence relations seen above, the meaning of these relationships has its origins as the category S1 and S2 and S3 target categories respectively. The consequence for the planning of an IS is to describe, for existing IF, or set for a change of SI, which applications must provide data to other IS applications.
In terms of dependency relationships, category F1 is bound by relations of dependence category type stock S1 and S2 and the coding type of category C1. Master data management system for centrally managing cached data representing core enterprise reference data maintained as locked in true state read only access until completion of manipulation process.
By following these principles, we get the category diagram oriented in Figure 4.
Conclusion : by issam essar on Prezi
A method according to claim 1, characterized in that the grouping of the categories according to a predefined typing is to define categories related to flow F comprised of generic concepts and specialized concepts that have a life cycle that exactly corresponds to that of a process, categories related to stocks S gathering generic concepts and specialized concepts that change state after activation of a stream and have an unlimited life cycle to that of a process and coding categories C grouping generic concepts for referencing information related to flows or stocks.
The various categories thus defined are linked with one another on the diagram by UML dependence relations each materialized by one or more reference data SI.
Encoding of functional entities on the basis of control data exchanged on a telecommunications network. Thus, this is the application which is located the bearing of the diagranme data D2 which must provide, via for example a service, the application containing the referential data D1 in its field and not the reverse. The chart categories 6 is therefore developed according to the principles defined by the UML modeling reference data of an IS according to the present invention.
This notion of data offering by a customer to supplier obviously impacts the functional planning of the SI. Coding categories, which include generic concepts that allow you to reference information related to flows or stocks for example, a type of category Commercial Catalog. However, data clux proposed in a Conceptual Data Model from the Merise method does not translate the repository notion of a given or a relationship between two data.
This location reference data fields to determine what data repository, that is to say, under the responsibility of any application, must be given referential.
The urbanization job then is to define the main lines of these continual developments and trends and enable a simpler interconnection between different systems and applications SI. This typing classes of flx IS according to the invention, and therefore the content concepts or corresponding data to specialized concepts is defined as follows in conjunction with Figure 1: Commande A category related to the flow F: This embodiment of the invention is that an existing SI in which, for planning purposes, the description of the reference data and their deposits is required.
In other words, if the referential data containing the relationship between two referential data D1 and D2 is in the same field as the referential data D1, then the dependency relationship between the corresponding generic concepts, CG1 for D1 and CG2 for D2 is oriented towards CG1 CG2. The location method according to the present invention requires entry into a category diagram where all dependence relationships are aligned with the previously defined principles.
It is the application that the deposit contains the referential data describing a customer must provide this data to the application that the deposit contains the referential data describing a customer commercial fleet.
Also, in view of the meride, an object of the present invention to provide a method of data modeling of SI which overcomes the disadvantages of the aforementioned prior art, particularly that provides a mapping of repository notion of a dependency relationship between data and data themselves.
The present invention relates to a method for modeling reference data of an information system ISas well as an algorithm based on this model, allowing the location of reference data fields of a system ‘information. The invention thus relates to the field of software techniques.
Regenerating data integration functions for transfer from a data integration platform. Meride orientation of the relationships between categories, previously only meirse on the relationships between data SI studied, was first linked to the typing of these categories.
These categories can be represented by the concept of UML package.
Meaning of “merise” in the French dictionary
Verfahren zur Modellierung von referenziellen Daten und seine Verwendung zur Ortung von referenziellen Daten in einem Informationssystem. To do this, the invention proposes to apply the concept of object modeling UML, acronym for “Unified Modeling Language” for modeling reference data of an information system.
Also, in this context, any data of an IS can be interpreted as the implementation of a specialized concept UML class stereotype.
According to one characteristic of the invention, the step of locating the reference data field associated with a category of designating the responsibility of any application is the reference data related to said category.
