A

C

Client

Workstation computer of a user. Uses the applications or resources provided by the server.

Cloud computing

Displacement of IT resources (memory, software) to central servers that aren't considered to be part of the company infrastructure but rather made available by independent third-party providers.

Collaboration

Teamwork between employees with the aid of functions of a software platform. The context menu of every element can be access with the right mouse button.

Control

Elements, for example from the Applications and Design modules are also called controls.

Foreign key

Foreign keys are used to identify data records which are stored in other database tables but are related to data records from the current table. Departments are saved in the following table.

Primary key	Department
1	Sales
2	Marketing
3	Support

The next table contains employee data.

Primary key	Department	First name	Last name
1	3	Betty	Miller
2	2	Sam	Cook
3	2	Ralf	Miller
4	1	Sam	Hampton

The primary key of the department is saved as the foreign key in the Department column. This makes it very simple to identify, for example, that Betty Miller works in the Support department.

G

GUID

The GUID (Globally Unique Identifier) is the unique identifier for each individual element in Intrexx. In expert mode, the GUID of can element can be identified using the Details dialog. Intrexx GUIDs consist of 160 random bits that are generated using a cryptographically secure random generator. This results in hexadecimal coded character strings with a length of 40 characters (e.g. 926B444D13B87CE9EEA22BBF9EDAA27A8C7DFE4D).

H

I

Installation directory

Refers to your Intrexx installation directory: on Windows e.g. C:\Program Files\intrexx and on Linux /opt/intrexx/.

J

K

L

M

Mandatory field

If the property Input required has been activated for an element, such as here for the Edit field, the element becomes a mandatory field. Saving a page in the browser is only perormed when all mandatory fields have been filled in. The user will be informed about empty mandatory fields by a notification before saving the data record.

N

O

P

Portal directory

All files of a portal can be found in the Intrexx Portal Server in this directory: on Windows e.g. c:/ProgramData/intrexx/<portalname>. You can determine the portal directory in the portal properties; this is reached from the Portal main menu.

Prefix

A prefix is placed in front of the actual term. If, for example, a data field is called STR_TITLE, TITLE is the term and STR_ is the prefix - the so-called data type prefix.

Primary key

Primary keys are used to uniquely identify data records. In the following example, the last name Miller and the first name Sam occur more than once. With the primary key, which saved in its own database column, each data record can be identified uniquely.

Primary key	First name	Last name
1	Betty	Miller
2	Sam	Cook
3	Ralf	Miller
4	Sam	Hampton

A primary key can also be assembled from a combination of various attributes, for example when multiple database tables are connected together in another table. It's important here that each combination is unique, meaning it only occurs once.

Properties dialog

The settings for an element are available in its properties dialog and can be modified there. The properties dialog can be opened by double-clicking on the element or via the context menu / Properties.

Q

R

Restart Intrexx services

Intrexx services can be restarted, for example, in Windows under Control panel / Administrative tools. You can recognize the Intrexx portal services because of the prefix Intrexx Portal followed by the name of the portal. The Intrexx Supervisor service is responsible for the distribution of licenses, downloading software updates among others. This very rarely needs to be restarted.

Tagging

Tagging describes the labelling of content. Tags are not predefined and can be assigned freely. The tags are gathered together to form a so-called tag cloud that provides information about how often a tag was assigned – the larger a tag is shown in the cloud, the more often it has been used.

Temporary directory

Temporary directories are used for caching files to be able to, for example, generate them fully without other applications accessing them during the process. Furthermore, the data isn't stored in the memory during the entire generation process in this way. You can access the temporary directory via the environment variable %TEMP% (Explorer or command line) in windows (e.g. %USERPROFILE%%/AppData/Local/Temp). The Intrexx client saves open processes in this directory, for example. Log files from processes are stored as XML files here. Normally, the Intrexx server uses other temporary directories, such as the /tmp directory in the Installation directory or internal/tmp in the Portal directory.
