An absolute identifier is a string of characters associated with each object in the repository. This string is computed using the date and time the session was opened, the number of objects created since the session started, and the object creation date (in milliseconds). An absolute identifier provides a unique way to identify an object in the repository, so that even if the object is renamed, all the links to it are retained.

Access area member groups all persons and person groups belonging to an access area. This area defines objects that can be accessed by the person or person group.

An access path indicates which folder you can use when creating a reference for an environment database or a site environment. When all repositories are created in the same location as the environment, the path created at installation (the DB folder under the environment root) is sufficient and is given as the default. When you want to save a repository in a folder other than that of the environment, you must declare a new access path.

User access rights are the rules that manage access to software functions and databases. You can restrict the access rights of a user to the different repositories defined in his/her work environment. You can also restrict what software features a given user can run, such as the descriptor editor, modifying queries, designing report templates (MS Word), deleting objects, dispatching private workspaces, importing command files, managing environments, repositories, users, writing access, etc.

Administration consists of managing the work environment of repository users. This function is usually the responsibility of the administrator. Administration tasks include making backups of repositories, managing conflicts in data shared by several users and providing users with queries, descriptors, report templates (MS Word), etc. common to several projects.

The MEGA Administration desktop (Web Front-End) is the Web version of the Administration (Windows Front-End) application accessible via an internet browser.

The administrator is a person who has administration rights to manage sites, environments, repositories and users. In addition to Administrator (who cannot be deleted) and MEGA users, created at installation, you can grant administration rights to other users.

See Characteristic.

A physical backup (GBMS only) consists of copying the files of a repository from their original location to another.

The backup logfile is an additional file stored outside the repository or private workspace. It ensures that the changes made to the repository or private workspace can be recovered even if the repository files become corrupted. Creation of this file is requested in the configuration of each repository (including the system repository). It is created when the first update is made in a private workspace or repository.

A business role defines a function of a person in a business sense. A person can have several business roles. Business roles are only considered when the "Management of assignment of business roles to persons" option is activated (default mode) A business role is specific to a repository.

A profile can be associated with a business role. Assigning a person a business role with which a profile is associated indirectly assigns this profile to this person.

A characteristic is an attribute that describes an object or a link. Example: the Flow-Type characteristic of a message allows you to specify if this message is information, or a material or financial flow. A characteristic can also be called an Attribute.

A command file is a file containing repository update commands. It can be generated by backup or object export (.MGR extension) or by logfile export (.MGL extension).

Descriptors allow you to create reports (MS Word) containing part of the contents of the repository. Descriptor for an object includes the object characteristics, to which can be added the characteristics of objects directly or indirectly linked to it. The readable format for each of the objects encountered is entered as text in Word for Windows. You can insert descriptors into reports (MS Word) or report templates (MS Word) or use them to produce reports. Descriptors can be created or modified using the HOPEX Studio technical module.

The desktop specific to each user contains projects, diagrams, reports (MS Word), etc. handled by this user. The user has a different workspace in each of the repositories he/she accesses.

Dispatching your work allows the other users to see the changes you have made to the repository. They will see these when they open a new workspace, either by dispatching, refreshing or discarding their work in progress

An environment groups a set of users, the repositories on which they can work, and the system repository. It is where user private workspaces, users, system data, etc. are managed.

An external reference enables association of an object with a document from a source outside MEGA. This can relate to regulations concerning safety or the environment, legal text, etc. Location of this document can be indicated as a file path or Web page address via its URL (Universal Resource Locator).

A functionality is a means proposed by the software to execute certain actions (for example: the shapes editor and the descriptor editor are functionalities proposed as standard).

General UI access defines if tools are available or not. By default, general UI accesses have value *A (A: Available, *: default value)

Descriptors, which are available with the HOPEX Studio technical module, comprise a tree of several successive groups. Each group concerns one object, and defines the query or link used to access this object from the preceding object. You can connect texts and other groups to a group. Users can define the order in which groups and texts are processed.

Importing a command file, a backup file, or a logfile consists of applying the commands in the file to this new repository.

An LDAP parameter is a parameter that exists in the LDAP directory and is associated uniquely with a MEGA attribute. For example, "mail" is a parameter of the "Active Directory" LDAP directory and can be associated with the e-mail of the person.

The LDAP server is the server on which the LDAP directory is installed. The LDAP directory can be an Active Directory directory.

A link is an association between two types of object. There can be several possible links between two object types, for example: Source and Target between Org-Unit and Message.

A lock is a logical tag assigned to an object to indicate that it is currently being modified by a user. Simultaneous access to an object by several users can also be checked. Locks apply to all types of object. When a user accesses an object in order to modify it, a lock is placed on the object. When a lock is placed on an object, another user is only able to view the object. This second user will not be able to modify the object until the first user dispatches his/her work, and the second user refreshes. This is done to avoid conflicts between the state of the object in the repository, and the obsolete view of the second user.

Logfiles contain all the actions performed by one or more users over a given period. The private workspace logfile contains all the changes made by a user in his/her private workspace. This logfile is used to update the repository when the user dispatches his work. For additional security, it is also possible to generate another log called the backup logfile.

Export of a logfile creates a command file from the logfile of user actions in a repository. You can keep this file and import it later into a repository. You can selectively export modifications made in the work repository, or those made to technical data (descriptors, queries, etc.) in the system repository.

A Login uniquely defines a user or user group. It can be assigned to only one Person or Person Group.

see "link".

see object type

The metamodel defines the language used for describing a model. It defines the structure used to store the data managed in a repository The metamodel contains all the MetaClasses used to model a system, as well as their MetaAttributes and the MetaAssociations available between these MetaClasses. The metamodel is saved in the system repository of the environment. You can extend the metamodel to manage new MetaClasses. Repositories that exchange data (export, import, etc.) must have the same metamodel, otherwise certain data will be rejected or inaccessible.

An object is an entity with an identity and clearly defined boundaries, of which status and behavior are encapsulated. In a MEGA repository, an object is often examined along with the elements composing it. For example, a Diagram contains Org-Units or Messages. A Project contains Diagrams, themselves containing Org-Units, Messages etc. Database administration frequently requires consideration of consistent sets of objects. This is the case for object export, protection and object comparison. Isolated objects are found by checking that each object is used in another object. For example, a Diagram containing Org-units and Messages is itself used by a Process, an Org-unit, a Project, etc. This functionality is available with the MEGA Supervisor technical module.

The export of one or several objects enables transfer of a consistent data set from a study to another repository. For example, export of objects from a project includes the project diagrams, together with the objects these diagrams contain, such as messages and org-units, as well as dependent objects. All the links between objects in this set are also exported.

An object type (or MetaClass) is that part of the database containing objects of a given type. The objects created are stored in the repository according to their type. Segments are used when searching for objects in the repository and when the metamodel is extended to include a new type of object. Example: message, org-unit, etc.

Object UI access defines user rights on creation, reading, update, and deletion on these objects and their tools. By default, object UI accesses have value *CRUD (C: create, R: read, U: update, D: delete, *: default value).

A person is defined by his/her name and electronic mail address.

A person can access MEGA once the administrator assigns him/her with a login and a business role (or profile).

The list of persons can for example come from an LDAP server.

A Person Group groups persons in a group. These persons share the same connection characteristics.

A private workspace is a temporary view of the repository in which the user is working before dispatching his/her work. This view of the repository is only impacted by the changes of the user, and does not include concurrent modifications made by other users. This private workspace exists until it is refreshed, dispatched or discarded. Note that a private workspace is kept when the user disconnects from the repository, unless the user indicates otherwise. A user can see modifications dispatched by other users of this repository without dispatching his/her own modifications. To do this, the user refreshes his/her private workspace. The system then creates a new private workspace, and imports the logfile of his/her previous modifications into it.

The private workspace logfile contains all modifications made by a user in his/her private workspace. It is applied to the repository at dispatch, then automatically reinitialized. This logfile is stored in the EMB private workspace file.

A profile defines what a person can see or not see and do or not do in tools, and how he/she sees and can do it. The profile defines options, access rights to repositories and products, read/write and read-only rights on objects. All users with the same profile share these same options and rights. A user can have several profiles. A profile is available for all repositories in a single environment.

When several users work on the same project, it is important to provide them with the means to work on a new part of the project without inadvertently interfering with previous work. To do this, you can protect the objects concerned by assigning to them a writing access area (MEGA Supervisor technical module). It is then possible to connect these objects to others, if the link does not modify the nature of the object. The link orientation determines whether or not the nature of the object is affected.

A query allows you to select a set of objects of a given type using one or more query criteria. Most of the MEGA software functions can handle these sets. For example, you can use a query to find all enterprise org-units involved in a project.

see "reading access area".

The user reading access area corresponds to the view the person or person group has of the repository: it defines objects that can be accessed by the person or person group.

The reading access diagram enables definition of reading access areas and their hierarchical organization. This diagram also enables creation of users and their association with reading access areas.

Refreshing his/her private workspace allows the user to benefit from changes dispatched by other users since creation of his/her workspace. In this case, it keeps repository modifications carried out by the user without making these available to other users. The system creates a new private workspace and the logfile of previous changes is imported into it.

When updating a repository (importing, restoring, dispatching), a reject file is created in order to store rejected commands. Rejected commands are stored with the reason for which they were rejected. These are found in the "MegaCrd.txt" file located in the environment folder.

Reorganizing a repository consists of executing a logical backup of the repository, reinitializing it and reimporting the logical backup (without log).

Reports (MS Word) managed by MEGA are objects allowing you to transfer written knowledge extracted from the data managed by the software.

A report (MS Word) element is the instancing of a report template (MS Word) element. It is the result, formatted in the word processing software, of execution of the query defined in the report template (MS Word) element.

The environment report file, MegaCrdYYYYmm.txt (where YYYY and mm represent year and month of creation) indicates all administration operations (backup, export, restore, controls, etc.) carried out in the environment. The report file is stored in the user work folder associated with the environment system repository: SYSDB\USER\XXX\XXX.WRI where XXX is the user code.

A report template (MS Word) is a structure with characteristics that may be reproduced when producing reports (MS Word). A report (MS Word) can be created and modified as many times as necessary; however to produce several reports (MS Word) of the same type, use of a report template (MS Word) is recommended.

A report template (MS Word) provides the framework for the report (MS Word), which is completed with data from the repository when the report (MS Word) is created. A template contains the formatting, footers, headers and text entered in MS Word. It also contains report template (MS Word) elements that allow you to format data from the repository. It allows you to produce reports (MS Word) associated with main objects of the repository.

A report template (MS Word) element is the basic element of a report template (MS Word). It comprises a query which enables specification of objects to be described and a descriptor for their formatting. When creating a report (MS Word) from a report template (MS Word), each report template (MS Word) element is instanced by a report (MS Word) element.

A repository is a storage location where MEGA manages objects, links, and inter-repository links.

The main part is managed by a database system (GBMS, SQL Server, or Oracle). The remainder is in a directory tree (content of Business Document versions, backup logfiles, locks.

The different users in the environment can access the repositories connected to it.

The repository log stores all the updates of users working in a repository. It is reinitialized during the repository reorganization procedure.

A repository snapshot identifies an archived state of the repository.

Creating a repository snapshot allows you to label important states in the repository life cycle.

The repository archived states for which a snapshot exists are not deleted by repository cleanup mechanisms (Repository history data deletion).

A physical restore consists of copying previously saved repository files.

The work done in a session is saved when you request it, or when you exit. By default, the software executes an automatic save (the time interval between two saves is specified in the options: Options > Repository > Background Automatic Save). Messages appear asking you to confirm saving the changes you made in each open report template (MS Word) or report (MS Word) (except during the automatic save). It is recommended that you regularly save your session to avoid losing your work if your computer locks up or loses power.

A session is the period during which a user is connected to a repository. A session begins when the user establishes connection and ends when he/she exits MEGA. Sessions and private workspaces can overlap. When you dispatch, refresh or discard a private workspace, a new private workspace is created in the same session. Conversely, a user can keep his/her private workspace when exiting a session.

A set is a collection of objects with common characteristics. For example, you can build a set of messages sent or received by a certain org-unit in the enterprise. These sets are usually built using queries, and can be handled by most functions of the software.

A setting is a parameter of which value is only determined when the function with which it is associated is executed. You can use variables to condition a query (HOPEX Studio technical module). When you execute this query, a dialog box asks you to enter these settings, with a box for each setting defined in the query.

See repository snapshot

You can associate text with each object found when browsing object descriptors (HOPEX Studio technical module). This text is formatted for MS Word. It presents what will be displayed for each of the objects in the generated report (MS Word). In the text you can insert the object name, its characteristics, and its comment. You can also insert the characteristics of other objects linked to it.

A user is a person (or person group) with a login.

A user is authorized to access certain functions of the product and certain repositories. Each user has a specific desktop in each database, and can connect to this desktop from any workstation in a given environment.

The code associated with the user is used to generate file names as well as a specific work folder for the user.

By default at installation, Administrator persons (Login: System) and Mega (Login: Mega) enable administration of repositories and creation of new users.

see "writing access area".

A writing access area is a tag attached to an object to protect it from unwanted modifications. Each user is assigned a writing access area. There is a hierarchical link between writing access areas. A user can therefore only modify objects with the same or lower authorization level. The structure of writing access areas is defined in the writing access diagram. By default there is only one writing access area, "Administrator", to which all objects and users are connected. Writing access management is available with the MEGA Supervisor technical module.

The writing access diagram is available if you have the MEGA Supervisor technical module. With this diagram, you can create users and manage their writing access rights for repositories and product functions. By default only one writing access area is defined, named "Administrator". Attached to it are the "Administrator" and "Mega" persons. This is the highest writing access level and it should normally be reserved for repository management. You cannot delete this writing access area.
