TermDescription
>>>>>>>>>>>>>>>>>>>>> A <<<<<<<<<<<<<<<<<<<<
access control list (ACL)A method of data security. An access control list (ACL) contains the permissions granted to a particular user or group when the ACL's corresponding object is in a particular state.
access permissions Permissions that determine user access to individual elements. The permissions reside in access control lists (ACLs), along with user and object state information. See also access control list.
ACL See access control list.
assembly A group of individual parts combined to form an integrated part. For example, a ball-point pen assembly includes a barrel, a top, a clip, and a refill cartridge.
attribute A descriptor for a database element. For example, the attributes for a ball-point pen refill cartridge could be NAME, LENGTH, INK COLOR, MANUFACTURER'S NAME, and PRICE.
attribute type The data type of an attribute value. Attribute types depend on the installed database, and can include CHAR(n), VARCHAR(n), SMALL INT, INTEGER, FLOAT, and so on. For a ball-point pen, the attribute type for LENGTH might be FLOAT, and INK COLOR might be VAR CHAR(20).
attribute value The data stored in the database for a given attribute of an element. For a ball-point pen, the value of attribute NAME might be Biro, and LENGTH might be 88.0 mm.
>>>>>>>>>>>>>>>>>>>>> B <<<<<<<<<<<<<<<<<<<<
bill of materials (BOM) A tabular list of parts derived from a parts structure in the WorkManager database and formatted according to BOM format specifications.
Bill of Materials EditorAn editor in WorkManager that enables you to edit a part's structure.
BOM format The values of parameters that control the appearance of part names within a BOM display table or formatted bill of materials. Three BOM formats are available:

Flat
Contains no parts structure. Combines parts of the same name on the same line with a total quantity.

Indented
Lists parts hierarchically, and indents part names to reflect the hierarchy.

Exploded
Lists parts hierarchically, but left justifies part names. This format is useful if an assembly has many parts and a complex structure.
business rules A pre-defined set of rules regarding how ECC creates elements.
>>>>>>>>>>>>>>>>>>>>> C <<<<<<<<<<<<<<<<<<<<
CD-ROM Compact disk read-only memory that stores programs and data.
child part A part in a tree structure directly below another one, which is its parent part.
class A group of database elements having the same attributes.
class type A group of classes having the same behavior and capabilities. The six WorkManager class types are:
  • $DOC (for document classes)
  • $PACKET (for packet classes)
  • $FORM (for form classes)
  • $NOTE (for note classes)
  • $PARTDESC (for part description classes)
  • $GENERAL (for general item classes)
    • clickTo use the mouse button to select a command or option from the WorkManager menus, or to select a push button or radio button in a window.
    client A workstation or PC connected to a WorkManager database server via a LAN and runs the WorkManager client software. Each WorkManager client has its own configuration files. See also Local Area Network.
    codeword A 16-digit hexadecimal number that sllows you to use a specific software product. WorkManager codewords must be listed in the License Server configuration file named /etc/MEls.conf.
    connectTo establish a communication link between a client and its server.
    current copy The file most recently attached to a document. The Document Editor's load command loads this file, unless you use the Document Editor's edit select command to specify another file to load.
    >>>>>>>>>>>>>>>>>>>>> D <<<<<<<<<<<<<<<<<<<<
    data dictionary A dictionary of precise definitions of the types of data you can enter for database object attributes. You can define Data Dictionary entries to restrict attribute values. See also attribute type.
    database An organized collection of data.
    database administrator The person who manages the underlying database.
    database server The workstation containing the database server software and the relational database. One server can service several clients. You can turn off the WorkManager administration functions included with each database server product.
    default A condition or value that a system already contains and that it uses without user intervention, such as data dictionary entries. Defaults help ensure that a data value is acceptable even when you do not specify a value.
    demonstration database A database containing files and elements used in examples, tutorials, and training exercises.
    depth The number of levels of data in a BOM parts tree. Structure numbers or indentations within the parts name column of a table represent the depth. In a structure number, the number of digits separated by decimal points indicates the depth value. For example, a structure number 1.1.1 shows three levels of data and has a depth of 3.
    desk A user's personal workspace in WorkManager. When you own a packet, the packet is on your desk. Packets move between desks as their corresponding projects move through the project states.
    dialog box A pop-up window that prompts you for a response and requires you to select a field or to enter data. Dialog boxes disappear when you respond to their requests or when you close their master window.
    directory A place to store files on a mass storage medium. Each directory contains entries for its own unique files. The directory information includes details such as each file's name, type, length, location, and protection.
    disconnectTo break the communication link between a client and its server.
    display table A table you use to control the display of the contents of a logical table. See also logical table.
    document A WorkManager element with $DOC class type where you can add a FILE sub-object, such as a drawing, model, or text file, which in turn points to an actual file on the file server.
    document management Management of documents only that reside in the database.
    dummy text An arbitrary text string (such as XXXX) that you enter in the blank spaces of the title block to indicate where to place text references.

    form A WorkManager element with $FORM class type that emulates a paper form, like an ECR, ECN, PO, or approval form. A form element has an attribute for each piece of information required on the form. You can apply access controls to attributes of forms, such as electronic signatures, so that only a specific user can access them.
    >>>>>>>>>>>>>>>>>>>>> G <<<<<<<<<<<<<<<<<<<<
    general item A WorkManager element with $GENERAL class type that describes non-part elements.
    group One or more users who access an element as a group. The members of the group are likely to be in the same section or department. See also OWNER, user, and PUBLIC.

    routing list An ordered list of individuals or groups, each with an optional suggested routing station and state. This list controls who should receive a packet.
    routing station The logical location where you send a packet. A routing station typically identifies who has responsibility for the packet, such as Engineering or Marketing, or what needs to happen to the contents of the packet, such as design, analysis, coding, or testing. Only packets can have routing stations. Routing station changes can only occur when sending a packet.
    >>>>>>>>>>>>>>>>>>>>> S <<<<<<<<<<<<<<<<<<<<
    schema, system The definition of the database tables that you load when you install a WorkManager database. The system schema is part of the WorkManager code and is not customizable.
    schema, user The definition of the user's data, including classes, attributes, elements, Data Dictionary entries, users, groups, routing lists, and access control lists. You can load a user schema into an existing database and customize it.
    security See License Server.
    server A program that provides data or services to a set of clients. See also database server, file server, and License Server.
    sessionA connection to the WorkManager database using a WorkManager login name.
    startup file A file that executes automatically during startup. The file contains instructions for loading macros and system configuration information.
    state An optional attribute of all elements, ACLs, and routing lists. Normally, a company uses state to indicate specific checkpoints and milestones in a project, such as Development or Released. These typically involve specific review meetings or processes, sign-offs, and change of access permissions for the objects involved. ECC uses states to control access to a packet or any other WorkManager element.
    structure number A number indicating the hierarchy of data in a BOM parts list. A structure number consists of digits separated by decimal points. For example, a structure number 1.1.1 indicates three levels of data.

    tar An operating system command that transfers the contents of a storage medium to a hard disk, which you use while installating WorkManager.
    template An ASCII file containing one or more lines in comma-separated list format, which WorkManager interprets to produce a user interface object. Templates let you manipulate element attributes and information. Do not confuse a template with a form. A form is an element, while a template is a file that produces a user interface object.
    text reference An info string you assign to text in the title block template. It is essentially a link between a text field in the template and drawing attribute data in the database.
    text reference name The name that appears in text fields when you first place a title block, or when you use the Display TR Names command. For example, tb:OWNER and tb:NAME are text reference names.
    text reference value The actual data that appears in the text reference field when you use the UPDATE command. The value depends on the drawing. For example, danm and saw_part_d could be text reference values.
    title block An on-line "form" added to drawings to provide information such as the drawing name, creator, and revision. This block appears when you load a title block template into your drawing.
    >>>>>>>>>>>>>>>>>>>>> U <<<<<<<<<<<<<<<<<<<<
    unique identifier A combination of one or more attribute values that uniquely identifies an element in the database. The unique identifier can be different for different classes. For example, in the DRAWINGS class, the attributes DRAWING_NO and REVISION could make up the unique identifiers. In the PARTS class, they could be PARTNO and REVISION.
