Is this the best way to unpivot data?

Hello hive mind,I am calling an API that gets me some foreign exchange rate data (all from USD). The data that comes back is in this format:timestamp AUD EUR GBP 2024-04-24 12:00:00 1.538766 0.935636 0.803964  I’ve highly simplified this. There’s a possible169 currencies here, I’m only showing 3. I need to unpivot it and get it into this format:timestamp from_ccy to_ccy rate 2024-04-24 12:00:00 USD AUD 1.538766 2024-04-24 12:00:00 USD EUR 0.935636 2024-04-24 12:00:00 USD GBP 0.803964  My current plan looks like this: It is fine for 3 currencies. But not fine for 169!Anyone got any ideas for steps I can use to keep my plan clean and tidy? (And that I don’t have to make 169 copies of Alter Format 😱)

How to join tables for cross-entity checks? ✅

Hi everyone!Data quality management often requires comparing data from various sources and performing cross-entity checks to ensure accuracy and consistency. In this post, I’ll walk you through the process of creating cross-entity checks. Let’s get started 👇🏻 An Overview of the General StepsTo perform cross-entity checks, you need to follow these five key steps: Create a Virtual Catalog Item (VCI) in IDE: The Virtual Catalog Item acts as a container to hold the tables you want to compare.   Join the Necessary Tables: Identify and join the relevant tables from your data sources that can be merged for comparison. Sync the VCI with the Web Application: Ensure that the Virtual Catalog Item you created is synchronized with the web application for further processing. Create a Rule to Compare Data: Develop a rule that specifies the comparison logic for data across different tables. Create a Monitoring Project: Set up a monitoring project to compare table values at a specific periodi

Getting Started with ONE DG: Workflows 🧑‍🏭Best Practice

Happy Wednesday Community! Today we will talk about workflows - let’s dive into it right away 🤿 Currently, workflows in Ataccama ONE are focused on the access request process. They offer additional automation for requesting changes to data access in ONE. Here are some key actions that workflows allow:If you have insufficient access rights on a node, you can request a higher access level from the node owner. The default assignee of the task can either approve or reject the request from the Kanban Board. For more information on tasks, check out our previous post on the community here.Before you can request access to entity data, make sure you meet the following prerequisites:The workflows:ableToStartRequestDataAccess trait must be enabled on the entity. Data access requests can only be enabled for the following entities: Catalog Item Source Location Connection Monitoring Project To view the list of workflows, navigate to Tasks And Workflows > Launched workflows tab.

Change source on Monitoring Project

Hi,I created a Monitoring Project with a Catalog Item Loan from Source A. In the Monitoring Project I apply 100 DQ checks and I'm very happy. I want to change the source afterwards because I'm done checking the CI Loan from Source A and need to check the same CI (not same data) from Source B. Is it possible/doable to change the underlying Source A to Source B keeping the 100 DQ checks in the same Monitoring Project? I heard it was possible, but couldn't find it anywhere in the community.

Use case for Security terms

Hi Community!I was wondering if anyone has used the Security term (as extension of term) functionality in OneWeb and if so how. There seems no documentation available from the Documentation portal or the Community to clarify the modeling choices. The node has the following properties regulation is a string instead of a reference to node regulation and responsiblePerson is also a string. The effectiveDate is not of type date but string as well. Why would this be?Anyhow, I would appreciate if anyone can shine some light on this.Thanks and kind regards!Albert

How to connect to Hive Warehouse Connector?

We want to profile Hive managed tables in our Cloudera data lake. This is only possible if the Hive managed table is defined as non transactional. However to turn of that feature you need to rebuild the table. We had a discussion with our architecture team and they don't want to turn off this functionality.The other option then is using Hive Warehouse Connector. It is known that this has some performance costs. But we want to test this anyway.Is there any documentation on using this feature?

TWS Integration

Hey all, Has anyone been able to integrate with TWS for kicking off Reconciliation or Data Quality Project runs? I have users asking if their DQ Projects can run after their jobs have run which are scheduled by TWS. I was thinking that there has to be a way that Ataccama could listen for when a TWS job runs and finishes, it could kick off a DQ or Reconciliation project to also begin running. Has anyone successfully set this up before? either in the Orchestrative server or within Ataccama Desktop?Thanks

Customisation & Theming

Building upon the excellent work of our Flamingo design team, and a fun gradient ranging between purple and “electric” pink, I like to think that Ataccama looks pretty cool by default. However, we fully appreciate that many businesses have a need to customize their enterprise software to match their corporate brand and identity. This brings us to today’s topic… customisation!In this post we are going to cover how to set custom logos and colour themes in Ataccama DQG.  By navigating to Global Settings → Customization, it’s possible to perform a range of customisations in Ataccama DQG. As well as options for custom Translations (pirate, anybody?) and Navigation layouts to reorder and customise the sidebar, you can use the Theme section to fully customise the colours of the UI itself*, aswell as change the top logo to your own.Indeed, this last feature is as simple as drag-and-drop: You may have also noticed that this navbar is not purple! Here, we used the “Moon” theme, but there’s many

Getting Started with ONE DG: Ataccama ONE Catalog 101 📖Best Practice

Hi Community! We are kicking off a new best practice series covering the basics of ONE DG. Each day for the next two weeks, we will dive into a new topic to level up or strengthen your ONE DG skills 💪 First things first, before starting our how-to articles let’s learn the essentials we will be using for the ONE Web Application. Knowledge Catalog is where you'll find the key tools for data management, including importing metadata from data sources, viewing, discovering, and profiling data. Let's explore the two main sections of the Knowledge Catalog: Catalog Items and Sources.Catalog items house your actual data, organized into attributes—think of them as columns in a table. These items are imported into the platform from various sources representing different storage types.Business Glossary serves as the central repository for business terms.Business terms are labels assigned to the data that help you understand and organize your data. You can also create hierarchical structures betwe

Passing a parameter from a workflow to a component with a parameterized SQL query

I have a workflow that runs multiple components. In the workflow I have a parameter called load_id that I would like to use to query all kinds of tables later in the flow. But if you use a JDBC Reader in your component you can't use the parameter in the query. You could if you were able to do an Alter Format before the JDBC Reader, but JDBC Reader allows no input.I've seen some tips here in the Community, like these: But initially I still ran into some issues before I got it working. So I decided to share a working example.This is my very simple workflow.It only has a Run DQC task that will run the component.But let me show the global variables in my workflow. I hardcoded the load_id, so my query would get rows back. Now lets look at the configuration of the Run DQC task: As you can see, I run the parameterinquery.comp component and pass on the load_id with the expression """"+load_id+"""" .On to my component:The Random Record Generator is the start of this, because with the JDBC Reade

Layout change of preview pane in OneWeb

Hi Community,In a term's listing (overview) page you can click on the term's name after which the detail page for that term opens.

So like this:In the details screen it is possible to change the page layout, which is especially important after having added custom properties, so that a logical layout can be retained.It looks though that for this preview pane the layout cannot be changed. Does anyone of you know how to accomplish this?Kind regards,Albert

Variables in Json Call debug filename?

I know that it is possible to use variables in filenames in a Text Writer (see here: Text File Writer: adding a datetime as suffix to an output file (ataccama.com)). But what about the Request and Response Debug File in a Json Call?I have a component for ServiceNow integration and I want to reuse another component to retrieve incident details. But when I run the main component I get this error:File file://d:/Ataccama/workspace/SNOW/distribution/debug/03_getincdetails_request_debug.txt must not be multiplicatively accessed in writing mode.The only way to get it all working, is by removing the Request and Response Debug File in the Json Call that gets incident details. A possible way around this would be if I could use variables in the filenames. But this does not seem to work in the same way that variables work in Text Writer steps (by putting the variable name between { } ).Is there another way?

Can we restrict Ataccama One User Management to Users' Stewardship group

Hello everyone,I’d like to set up access permissions in Ataccama One so that users within a particular stewardship group are limited to making changes only to that specific group (e.g., adding/removing users from certain roles within that group)?For example, HR users should only be allowed to make user related changes within the confine of the HR group.However, the user management seems to be a global page and does not have stewardship-specific access.

How do i do data quality on inbound text file objects

Hello:I really appreciate the commnity helping me solve more use cases and get value out of the investment we made in Ataccama. Now - i have another area that i need help with.We have a vendor that drops a file every night - this is not comma delimited and not fixed length. Based on the first character of the line, it decides the format of that lineFor ex: if char(1) is - 1 - then the lenght of the file will be 10 characters with first 5 characters as identfier and next five char as status.But if the first character is 2 - that means it is a different type record (type 2), that has 100 characters in length - and each of them fixed length positions. Now - when i scan that file through Ataccama, it is thinking the file attributes based on the first row. But is there a way i can give the metadata to the profiler?And by the way, i need this to be a monitoring project that runs DQ on a demand basis (that i would like to trigger through Airflow when the file arrives)can some one give me some

And when i add the checks to the Catalog item, they are not coming to monitoring project when i add that catalog item to the MP.Iam needing to add/configure all the rules separaely - both at Catalog item level (to get DQ percent score for that object), and also at the Monitoring project level. Is it possible to add the DQ rules - just to the Catalog item, and when I add that catalog item to the MP, it should automatically bring the existing rules on that object into the MP?​​​​
