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
are not 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).

IoT - Internet of Things
The Internet of Things is a network that consists of many intelligent
devices or systems that interact with one another via M2M (machine to machine).
In the health sector, the industrial sector and the enterprise resource
planning, objects are being equipped with intelligent sensors for this
purpose. Each intelligent object can be identified using a unique
internet address and can be addressed in the Internet of Things
via this.
Installation directory
Refers to your Intrexx installation directory: on Windows e.g.
C:\Program Files\intrexx and on
Linux
/opt/intrexx/.

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.
Microsoft Office Graph
The Microsoft Office Graph is a backend tool in Microsoft Office 365
that interconnects the searching and locating of information
in different sources of Microsoft Office 365 automatically.
This is a solution that compiles all of the important information
and documents across all repositories and Microsoft Office 365 programs.
Microsoft Office Graph possesses a uniform programming interface (API)
that servers as the access point for every type of search request.
The
Connector for Microsoft Office 365
uses the Graph API to access content in Microsoft Office 365.
MQTT
MQTT (Message Queuing Telemetry Transport) is a messaging protocol
based on TCP. It is open, simple and
designed to be implemented easily.
MQTT is characterized by low overheads in the communication,
but provides stable message delivery nonetheless.
With these properties, it is ideal for use in many situations
including limited environments, such as for communicating in
machine to machine (M2M) and Internet of Things (IoT) contexts
with low, limited or expensive network bandwidth, but where
information should be provided or consumed regularly despite this.
Practial areas of use, where MQTT is already well used, include
"Track & Trace" applications that record a wide variety of
readings (e.g. temperatures, rotations, water levels etc.).
The devices can range from monoboard computers (SoC), such
as a Rasberry Pi, which has been expanded with
the corresponding sensors, via smartphones, which provide the
corresponding values for mobile devices, through to industrial
manufacturing facilities, where the production and hardware status
should be monitored.
An MQTT client can act as a "Listener", which listens
to messages from other MQTT clients, or as a "Publisher",
which sends messages. The mapping of the messages is organized
into channels, so-called "topics", this means that in the simplest
scenarios, two MQTT clients can "talk" when the same topic is
selected for both of them. In this simple scenario, this can
be enough to receive reports about the water levels in a hydroelectric
facility on your smartphone, for example. However, as soon as
multiple clients are involved and there are various topics
available, or also in use, or access needs to be made secure
accordingly, a so-called "Broker", meaning an MQTT server,
is a good solution. This also provides the facility of
implementing additional protocols such as JMS (Java Messaging Service).

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.

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.
S
sharedState
An optional
global shared state
is available in many
event sources and timers. If
this is defined, the same shared state is used for all events of the source.
T
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 is not 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.
