How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Electronic Data Interchange (EDI) developer with XML with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Electronic Data Interchange (EDI)
What is Electronic Data Interchange?
Electronic data interchange (EDI) is the electronic exchange of business documents between organisations. Business workflows often require routing and sending documents such as invoices, purchase orders and shipping forms from one organisation to another. These documents can be attached to emails or communicated over the phone or postal mail and sent to a human representative of another organisation who will process them and record the information within its enterprise data systems. EDI is a standardised technology that automates these workflows so that digital systems within an organisation can communicate with and share documents with another organisation, digitally. These systems can automatically process these documents communicated over an electronic network without human interaction. Since IBM’s Invoicing by Wire was created in 1959, many organisations have connected their IT systems to the IT systems of another organisation so that they could communicate within a B2B network to save time and eliminate formatting errors that accompany document transmission and human-processing such as copy-pasting and data entry.
What are the benefits of electronic data interchange?
EDI provides the following benefits to businesses:
Save time
Invoicing accounting checks and purchase orders going back and forth, going from one person to another: if you’re not using EDI that stuff takes forever. There is no physical requisitioning, everything is automated – you just have to push an order, and the supplier receives it and replies. With a low-code environment, you can always go in and say OK, let’s automate this file processing step that everyone does, going from this menu to this field or that field. You can do all of that more conveniently in an EDI environment.
EDI also gets rid of the delay inherent in paper-based communications. It provides the near-instant delivery and exchange of business documents. Instantaneous transmission of electronic documents will facilitate faster response times and quicker decision-making.
Reduce errors
Due to the fact that EDI’s processing is automated, errors that usually occur when you key in your data manually are eliminated. Secondly, if anomalous data occurred in the document, EDI can help point out such instances. Once the document is set at a higher level of accuracy, we can identify the error and improve the efficiency of data processing.
Increase security
It is far more feasible with EDI. Your digital certificate gives you far better control over user access and authentication. Authorization and security of access are vital with EDI. EDI accomplishes access control through a combination of authentication and encryption. (Authentication checks if an entity claiming to be others’ trading partner has the rights to use the EDI access credentials, while security checks if an electronic message is lait sels, or safe for users to open; often it is used interchangeably with encryption: read the response to examine the difference between these concepts.) EDI makes access control far easier and more foolproof than paper-first decision trees, because the electronic system is far more secure than a paper-first system.
Enhance connectivity
If you want to collaborate with business partners, users and vendors by simply transferring large data sets, such as those undergoing product tests, via cloud-native file transfer services, you’ll find that you’ll be able to enable this very seamlessly. And with regard to EDI transactions, you can easily integrate them into your business processes and enrich your present connectivity ecosystem in your company.
How does electronic data interchange work?
EDI works primarily by using two forms of transmission:
- A point-to-point or direct EDI connection connects two business systems with secure protocols
- Unlike the EDI system, the value-added network (VAN) transmits data through a third-party network.
EDI software uses a mailbox paradigm for document exchanges and batch processing, while SOAP, Secure File Transfer Protocol (SFTP), and HTTPS-based protocols such as AS2 help to securely send EDI documents over the internet. EDI communication standards, codified by organisations such as Accredited Standards Committee X12, Peppoi and ODETTE, also ensure certain basic data-governance rules and often introduce their own glossaries, nomenclatures and terminologies for the data in EDI transactions, all of which highly secure the data and ensure its quality.
EDI software can also combine two or more data segments to produce additional context for items in the document. Take the items and numbers in the order: EDI software might combine the lines ITEMQUANTITY and ITEMDESCRIPTION into the ORDERLINE container. Not only does this allow a richer context for the items and numbers (the lines of the order), but the structure is tidier than if we didn’t use the combination.
What does implementation of electronic data interchange require?
Establish infrastructure
The first step in setting up EDI requires a business to acquire and install any hardware and software components necessary to facilitate the transmission, integration, translation and pathway mapping of EDI documents. EDI software converts any business documents into the correct format to facilitate interaction with trading partners. Common EDI software components include:
Component | Description |
---|---|
EDI mapping programmes | Take fields in a file (names and addresses, say) and map them to standardised documents. |
Batch enveloping and de-enveloping software | Allowing senders and receivers to receive, wrap and unwrap transactions. |
Message routing | Carry the message through the network, to the correct recipient addresses, that the format of the message is compatible with the destination address. |
Generally, this also includes establishing and connecting to VANs, which are secure and reliable transfer conduits from one network to the next. If you want to host EDI in-house, you need to have the necessary hardware, such as network gear, storage, and servers.
Establish connections
Once you have your technological basis for your EDI system laid down, you need to onboard your particular business partners. Since you are physically processing and sending and receiving documents to and from your trading partners, you must have EDI standards implemented to enable secure communication with them.
For example, different industries, or geographies, can each favour a different EDI standard format. Once the proper trade partner standards are specified, the EDI system can be configured to send EDI documents following that same standard – now the values and context within your purchase order aren’t a big long mess for the carrier, but a clean, orderly EDI document. Contrary to what we’ve seen up to this point, EDI providers and their customers also configure VPNs, firewalls, or AS2 tunnels to ensure the transmission path is secure.
Adhere to standards
Your EDI system will need to remain in compliance with the standards required by your industry, which will include data protection regulations and standards. If your industry has standards (and most will), then every update to those standards must be met by your system. Similarly, if any trading partners change the standards they follow, whether that’s for specific customers or markets, you must be able to exchange information in the new standards that they have chosen.
What are the challenges of electronic data interchange solutions?
Implementation costs
The initial investment in implementing EDI in your business processes is significant: you need to purchase hardware, software and systems that are compliant to regulatory standards. Should you use a third-party EDI network provider, you also need to purchase services from them. Your staff must be trained on the processes, approaches, standards and software used, and you have to consider costs in this for one-off and regular training. You need to provide accessible training resources for your staff to learn.
Document mapping
Another hurdle is intelligently mapping the EDI format to deliverable and legacy documents. If you’re already using more than one system, you have to go through quite a bit of testing to ensure the integrity of your data-mapping. It can be a tedious task to manage if you don’t have the resources in-house to oversee the project.
Scaling challenges
Once you’ve deployed your EDI solution, you’ll likely need to scale your system across your logistics partners and vendors. For instance, purchase orders may contain different business rules, data elements and document fields depending on your trading partner. In order to scale your EDI system, you’ll need to adapt to varying degrees of EDI maturity among different vendors.
Ongoing monitoring
Inaccurate, incomplete or inconsistent information will pose a challenge for EDI solutions. You need to constantly monitor EDI systems and emerging security standards to mitigate risks of business disruption, data quality degradation or non-compliance. You should dedicate resources to continuous audits, security assessments and performance reviews to address potential emerging compliance issues.
Where is XML used?
Config Files: The Tidy Cupboard!
- Software settings love to chill in XML's neat drawers, like a well-organized sock drawer for developers.
Soap Opera of Services
- SOAP protocols gossip in XML messages like a postal service for chatty web services.
Ancient Scrolls of Data Exchange
- Before JSON muscled in, XML was the elder statesman for data sharing, trading bits like vintage baseball cards.
The X Marks the Spot
- In the treasure hunt of office templates, XML maps the way to riches in Microsoft Office file formats.
XML Alternatives
JSON (JavaScript Object Notation)
JSON is a lightweight data-interchange format. It's easy for humans to read and write, and easy for machines to parse and generate. Used primarily to transmit data between a server and web application.
{
"name": "John",
"age": 30,
"isStudent": false
}
- Human-readable and writtable
- Lightweight, leading to faster processing
- Widely supported across programming languages
- Lacks support for comments
- No support for namespaces
- Can be verbose for complex structures
YAML (YAML Ain't Markup Language)
YAML is a human-friendly data serialization standard for all programming languages. It's often used for configuration files and in data exchange where human readability is important.
name: John
age: 30
isStudent: false
- Highly readable syntax
- Supports complex data structures
- Uses indentation for scope
- Prone to errors due to indentation
- Can be slow to parse in large quantities
- Lacks security features by default
Protocol Buffers (Protobuf)
Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data, similar to XML but smaller, faster, and simpler. Used for storing and exchanging structured information.
message Person {
required string name = 1;
required int32 age = 2;
optional bool is_student = 3;
}
- Compact and efficient serialization
- Schema-based with clear contracts
- Backward and forward compatibility
- Requires pre-defined schema
- Not human-readable format
- Smaller ecosystem compared to JSON and XML
Quick Facts about XML
XML: The Hierarchical Heavyweight That Outgrew Its SGML Sibling
Picture it: 1996, the year the Spice Girls were telling us what they "really, really want" and the tech world got what it really, really needed – XML! Conceived as a simplified subset of SGML, XML was designed by a ten-member gang called the XML Working Group, helmed by its captain, Jon Bosak. They sought to make this data structuring and transportation champ both human and machine-readable, which is kind of like making broccoli taste like chocolate – ambitious but oh, so beneficial.

XML Speaks in Tongues: Namespaces and X-Words
Fast forward a couple of years to 1999, a world nervously peeking at Y2K, and XML 1.0 was spreading like the latest cat meme. But one set of tags wasn't enough to hold the convos across different XML vocabularies. Enter Namespaces in XML – not about outer space, but just as cool. This meant XML could play nice with HTML without overstepping tag boundaries. And with XSLT, XPath, and XQuery joining the party, XML had more X's than a pirate's treasure map!

XML 1.1: When It Decided to Get a Makeover
Let's zoom to 2004. Usher's 'Yeah!' was topping the charts, and XML was getting an upgrade to 1.1. And just like low-rise jeans, not everyone was thrilled about the change. This version tweaked character encoding and made it simpler to include special characters. Basically, XML went from the tech equivalent of a flip phone to a smartphone – more features, more emojis, but not everyone wanted to relearn how to text!

Top 10 XML Related Tech
Java/C#
Like peanut butter and jelly, Java and C# are the classic sandwich spread for XML manipulation – they're the bread-and-butter languages that play nice with XML right out of the box. Java has libraries like JAXB that can marshal and unmarshal XML faster than a cowboy at a rodeo, and C# has LINQ to XML that lets you query your XML documents as if they were SQL-database socialites at a high-tea event.
// Java example JAXB
Unmarshaller unmarshaller = JAXBContext.newInstance(YourClass.class).createUnmarshaller();
YourClass yourClassInstance = (YourClass) unmarshaller.unmarshal(new File("path/to/your/xmlfile.xml"));
// C# example LINQ to XML
XDocument xmlDoc = XDocument.Load("path/to/your/xmlfile.xml");
IEnumerable<XElement> rows = from row in xmlDoc.Descendants("row") select row;
XML Schema
The blueprint of the XML world – if your XML were a LEGO structure, XML Schema would be the instruction booklet, ensuring that each piece clicks exactly where it should. It defines the structure and types of data allowed, making it the strict librarian of the XML data files, always shushing incorrect formats.
// XML Schema example
<xs:element name="contact">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="phone" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
XSLT
XSLT is like the DJ of XML files, remixing and splicing together XML documents to produce a fresh new track... or in this case, a brand spanking new HTML, text, or another XML document. With XSLT, transform your data like a magical origami master folding paper swans.
// XSLT example
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>My CD Collection</h2>
<table border="1">
<xsl:for-each select="catalog/cd">
<tr>
<td><xsl:value-of select="artist"/></td>
<td><xsl:value-of select="title"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
XPath
XPath is the treasure map to your XML's gold – with it, point out the exact location of data in an XML document with the precision of a GPS system on a secret agent's car. It's like Where's Waldo, but your Waldo sticks out like a sore thumb.
// XPath example
String expression = "/class/student[@rollno='493']";
Node studentNode = (Node) xPath.compile(expression).evaluate(xmlDocument, XPathConstants.NODE);
XQuery
Picture a private investigator rifling through a drawer – that's XQuery in the XML database. It's almost synonymous with "Where's the beef?" but for data in XML documents, allowing you to extract the meaty information bits you actually care about.
// XQuery example
for $x in doc("yourdata.xml")//yourElement
where $x/yourSubElement = "value"
return $x
XML DOM
The XML DOM is your XML document’s family tree, but instead of Uncle Bob and Aunt Sue, you have nodes and elements as relatives. It lets you navigate and manipulate these family gatherings using JavaScript, turning you into the ultimate family planner.
// XML DOM example in JavaScript
var xmlDoc = parser.parseFromString(text,"text/xml");
xmlDoc.getElementsByTagName('title')[0].childNodes[0].nodeValue = "New Title";
SAX (Simple API for XML)
SAX is like speed dating for XML parsers – instead of getting cozy with the whole document, it darts through elements firing events, making it a memory-efficient choice for playing the XML field if you're tight on memory budget.
// SAX example
class UserHandler extends DefaultHandler {
public void startElement(String uri,
String localName, String qName, Attributes attributes) throws SAXException {
if (qName.equalsIgnoreCase("book")) {
String isbn = attributes.getValue("isbn");
}
}
}
Apache Camel
Apache Camel is like the Switzerland of application integrations, a peacekeeper that lets different systems talk in XML without throwing punches. It's an integration framework that routes XML messages between APIs like a postal service on steroids.
// Apache Camel routing example
from("file:data/inbox")
.process(new MyTransformer())
.to("jms:queue:order");
SOAP Web Services
The postage stamp on your envelope of data, SOAP envelopes XML web service requests and ensures they’re delivered properly. It's a protocol more formal than a penguin at a gala event, ensuring messages are formatted and transmitted with the decorum of a butler carrying a silver tray.
// SOAP request example
POST /InStock HTTP/1.1
Host: www.example.org
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://www.w3.org/2001/12/soap-envelope"
<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">
<soap:Body xmlns:m="http://www.example.org/stock">
<m:GetStockPrice>
<m:StockName>AAPL</m:StockName>
</m:GetStockPrice>
</soap:Body>
</soap:Envelope>
XML-RPC
Think of XML-RPC as your grandma's telegraph system, albeit less old-timey and more internet-friendly. This protocol allows remote procedure calls encoded in XML, letting software on different operating systems talk easily like pen pals from the '90s.
// XML-RPC request example
<?xml version="1.0"?>
<methodCall>
<methodName>methodNameHere</methodName>
<params>
<param><value><int>42</int></value></param>
</params>
</methodCall>
