Application menu
In your Intrexx portal, there is the portal menu, which you can edit here, and the application menu, which you can edit on the "Application menu" tab in the properties of your application. It typically consists of links to selected pages in the application.
ARR
Application Request Routing is an extension to Internet Information Services (IIS), which enables an IIS server to function as a load balancer. Click here for more information.B
Base URL
The base URL is the URL used to access your portal. It is defined in the portal properties and is made up of the protocol (HTTPS), the DNS name of the (virtual) host, potentially the port number, and the root directory "/" of the web application.Example: https://hostname.example.com/
To avoid problems with different browsers, the DNS settings of the client, certificate validation or the same-origin policy, we recommend entering the fully qualified host name when accessing the portal in the browser.
Business logic
The Intrexx business logic is responsible for the reading, writing and validation of data, as well as handling default values. Furthermore, it provides a data source abstraction layer.
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 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.Commit
The current state of applications, layouts or processes is stored in the corresponding Git repository.Context menu
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.D
DIV element
The HTML element DIV groups multiple elements together in one area. The application element Grouping can, for example, be defined as a DIV container.E
F
Fallback value
A parameter, which is demanded by a target page, can be populated by the caller with a value. It is also possible to string fallback values together in this case. Based on the principle of "first match", the first fallback value to deliver a valid value will be used at run-time. Parameter values, which are the same for all or at least the majority of callers, can already be predefined with values at the target page. A fallback value chain can also be created here. If the caller does not provide a valid value for the parameter, then the fallback value chain of the target page will be worked through and the first valid value found will be used. If a valid value for a required parameter cannot be identified neither from the caller nor at the target page, then the target page cannot be viewed/used.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
Git
Git is a distributed version management system for files. In Intrexx, Git is used for the History of applications, processes or layouts. Earlier states can be reconstructed with it. The documentation for Git can be found here.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
Horizontal scaling
The performance potential of an IT infrastructure can be increased with vertical or horizontal scaling. Vertical scaling means that existing server hardware is upgraded (CPUs, memory etc.). Horizontal scaling means that new servers are added to increase performance.I
IIS
Internet Information Services is an extensible web server created by Microsoft. Click here for more information.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/.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 performed 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 back-end 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. Practical 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).
Multi-tenancy
Multi-tenancy is used in information technology, when multiple tenants, meaning customers or orderers, can be served on the same server or software system without them being able to look into each other's data, user management etc. A system does not become multi-tenant capable by creating an individual instance (copy) of the system for each tenant.N
Namespace
A namespace is a context, within which the names are unique. Namespaces can be hierarchical, meaning the names within each hierarchical level are unique. Examples:- Football: Namespace is the team. The shirt number is the unique name within this.
- Telephony: Namespace is the dialing code. The connecting number is the unique name within this.
- Domain name system (DNS): Namespace is a second-level domain. Here, the hostnames (www) and the subdomains (dev) are unique.
- URIs (Uniform Resource Identifiers): Each URI can be regarded as name with the superordinate resource as the namespace.
O
OData
The Open Data Protocol (OData) is a standardized web protocol. It supports the simple integration and manipulation of data and is designed in a significantly more user-friendly way than previous web services for developing web and mobile applications. OData is based on open web standards like HTTP, Atom Publishing Protocol and JSON, and like the World Wide Web, is constructed based on the REST (Representational State Transfer) architectural style. Complex database requests can be accomplished with OData using the URL alone. Consequently, OData is also known as ODBC for the web.P
Portal
An Intrexx portal can be created in the Portal Manager. You can choose from various portal templates for your new portal. The portal can then be opened and used by any number clients directly in the browser. The new portal comes with a menu structure and applications that can be adjusted to your specific requirements.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 menu.Portal Manager
The Portal manager can be installed by itself or together with the Intrexx Portal Server. It controls all of the components for developing and managing layouts, menus and applications. The permissions for the portal users for applications and data are also controlled here. The Portal Manager can be started either from the program group or via the desktop shortcut. On Linux systems, you will find manager.sh in the installation directory client/bin/linux. You can connect to an Intrexx Portal Server and administrate the portals on the start page of the Portal Manager.Portal page
Relevant information is displayed in portlets on a portal page.Portal Server
The Intrexx Portal Server controls all of the transactions from the portals and applications created there. It monitors the permissions within the transactions, controls the entire business logic and manages access to the data sources. You can connect to an Intrexx Portal Server in the Intrexx Portal Manager.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 is important here that each combination is unique, meaning it only occurs once.
