Compare data between file and table

we need to achieve completeness DQ control by comparing data in the file and the table irrespective of the position of primary key in either of them or by using composite keys. - This is in continuation with the query posted in ataccama community - Regarding DQ controls (ataccama.com) Do we have any step or document to follow on how we can import that file into ONE web app as catalog item and can we upload the file from local or we need to get that from the file system? Thanks,Karthikeyan.

Duplicate detection with aggregation results config

I have created a rule that detects if a record is in the table more than once based on aggregation of 2 attributes in OneWeb application. This gives a proper result in Invalid samples data and exports giving 2 errors if the record is in the table 2 times etc. But the customer requires that only 1 record should be visible in Invalid samples and also in exporting to db. It does not matter which one. Is it possible to configure the result to do this?

How to use Dynamic Expression Assigner?

Hi I'm Srija, Solutions Consultant here at Ataccama.In this post, I’ll walk you through how to use a dynamic expression assigner. What is a dynamic expression assigner?The Dynamic Expression Assigner in Ataccama allows you to define dynamic expressions or rules to determine how values are extracted or assigned to specific attributes based on conditions present in your data. Use Case:The Monitoring project results will give the attributes , Invalid DQ rules and Invalid DQ Attributes for the failed rows. If we need to extract the DQ Error Attribute Value based on the Invalid DQ Attribute then Dynamic Expression Assigner can be used in the post processing plan.In the below example, I have a DQ_Error_Attribute which is causing the issue for that record. If I need to extract the respective value of the DQ_Error_Attribute then, I can use the Dynamic Expression Assigner. We can achieve this using a column assigner, but we must hardcode the attributes to extract the value. If any new attribute

data reconciliation for snowflake data

Hi Team This is the continuation of the of the below thread about using reconciliation project for comparing a file with the table.Compare data between file and table (ataccama.com) The data compare is working fine when I followed the approach suggested. But from this link (Data Reconciliation Best Practices 👾 (ataccama.com) - it is mentioned as (except snowflake data).So, what will be the approach for the snowflake related connections. I have one more question - for eg ., I have column fullName in source (which has a full name) in target I have two columns one has the first name and other column has the second name. Can we compare source column to target column1 and 2.

DQ rule using complex lookup

Hello,I was wondering if someone has an idea to help my question about one of my DQ check. Basically let me explain what i have and what i want to achieve with them.I have; one list consisting 2 columns. Column A has unique values having 2 or 3 digits with a mixed combination of letters and numbers. Column B has names according to the column A. Here is the example: Column A Column B abc name1 abd name1 abe name1 abf name2 xy name3 1a1 name4 1a2 name4 1a3 name4 yz name5 yz1 name6 As you see, there is no corelation between column A and column B. I can’t assume if the value of column A is yz and value of column B is name5 then i have name5 for yz1 of column A.And I have a field in my data lets call it as column C. Column C has values with a mixed combination of digits and letters and with different length. Such as abc1231422ad , 1a3577afdg , yz4564sdfsfs can be example. And I have another field which is Column D having some other values. I want to check v

Business glossary - customization (part 1)

Hi Community,I’d like to share some thoughts about the business glossary. After considering how we wanted to use the glossary, we applied customizations in the metamodel, so we have a specific implementation. I suppose that others have a different approach to using the glossary, so it would be great if we could share and discuss our visions. I am looking forward to your feedback!Let’s start.The business glossary provides a way to describe terms that have relevance to the organization. Obvious properties like name, definition and owner describe a term. It is possible to connect catalog items and its attribute to a term, so that physical data elements becomes meaningful.The question is, can we describe these elements with the same properties? (Indeed a rhetorical question)To logically describe a catalog item attribute, besides its name and definition also properties like its (logical) datatype, an indicator to mark a ‘personal identifying information’ term and the GDPR classification.The

Start Ataccama server without opening Ataccama Desktop tool

I'm currently using the "start-server.bat" file within the Ataccama Desktop tool to manually start Ataccama Server. However, if I forget to start the server, certain workflows fail to execute. I've attempted to automate server startup using Windows Task Scheduler, but it's not working as expected. Is there a reliable method to start Ataccama Server independently of the Desktop tool, perhaps through a scheduled task or another approach?

Can term detection rule use both data and metadata both in the same rule?

Hello: I have a use case specifically for assigning a term. If the data is a 9 digit number and if the field name is NOT one of the list i want to exclude - then that term be assigned. I also have additional field names that i want to be tagged with that term - irrespective of value with in that field.As of now - iam able to create separate rules one that runs on metadata and other runs on real data - and put a OR condition or AND condition between the two rules. But that is not addressing my use case very well. I need one rule that can refer to both real data and metadata. OR - i should be able to give a complex join condition with more than two rules(Rule 1 AND Rule 2) OR (Rule 3) Has anyone done something like that?

Attaching a client certificate in a Json Call step

I’m trying to build a GET API call to an external data provider.This provider requires me to send my GET call with the certificate.We managed to test it in POSTMAN, where I had to add the certificate in the Settings → Certificates menu: I have a .pfx file with a passphrase, and I needed to specify the host.This works on my laptop in POSTMAN. Now I’m trying to do the same call in ONE Desktop using JSON Call step.By way of googling, I’ve managed to convert my .pfx file into .cer, then I imported the .cer file into {DQC_HOME}/jre/lib/security/cacerts . Then I have restarted ONE Desktop. But when I call the API I’m still getting an error message from the other side saying my certificate is not sent. I have a suspicion that the certificate is sitting in the keystore but it is not used. Is there some way to ensure it is used? Some java parameter somewhere?

Microsoft Teams Notifications - incoming webhook is discontinued for new configurations

Hey all!Now that incoming webhooks within Microsoft Teams is discontinued (Existing configurations will work until end of 2025), is there a plan for how teams will continue to integrate with notifications from Monitoring Projects? This was a big sell to a lot of our users, and now that we are unable to use incoming webhooks for new monitoring projects, I want to see if there is a plan to have a work around, or if it will be not supported in the future.

Day over day changes for certain data

Hello: I have a use case where when the data in a given column - for a key changes from previous day to next day - that should trigger an alert/notification For Ex: Security Ratings, and/or ESG ratings generally dont change for a given security. I have a table that has one record for each day for each security. And the ratings are in the columns of that table. Now - on a regular day - all ratings from previous day should be same for next day, and day after (until it changes). And on the day when it changes - i want to capture that security, ,what field changed - what was yesterday;s value vs todays value. The way - i would like to solve this - is create a SQLCatalog item - with previous day - and current day values combined into one dataset for each security and write scripts to compare them one by one, and report any changes. But I want to know if there is an out of box - date driven compare that can be done for this.

I am aware that profiling checks this but I have a requirement to check the data type as well. There don’t appear to be any parse functions in the interface. Any help would be appreciated, I am a noob so please be gentle :)

Export functionality visiblity

Hi,13.9.4Currently we have a monitoring project with several DQ rules applied. We also build in ONE Desktop an export functionality through components in order for the users to click one button and get a .xlsx file to see all the invalid records.ONE Deskptop componentWhen the .xlsx is downloaded and opened you will see the following:ExportAs you can see the same rules is shown multiple times with every time because a record can have multiple invalid rules applied on them hence the several options. This creates a list of invalid rules and for the user it's not a great experience to filter through the file. Is there a solution to this?I also want to take the moment to ask another question. As you can see you’ll notice “FLOAT is empty”. That is a generic rule we make available for every user. Input attribute is a float and it's checks whether the field is empty. If yes, it's invalid. This rule can be applied to any attribute that is a float data type. However in the invalid records I

Is there a way to see the plain values of prebuilt lookup lists?

Hello!I had a user pose the question of being able to view the plain values of lookup lists that came out of the box with Ataccama. When attempting to look at the lookup lists, it is unreadable from the Web UI, and the Desktop application. Is there any listed documentation of what these lookup lists contains, or a desktop plan to transform the lookup lists into a plain English format?Thanks!

Delete dataset from report (Monitoring Project)

Hi,ONE Web > Monitoring ProjectI have a MP A which contains 7 CIs, I want to copy this MP to create MP B. For MP B I only want to use 6 out of the 7 CIs as the last CI is unnecessary. I use the import configuration (great qol btw) and for the 7th CI I use same CI.After the import configuration has been completed I delete the 7th CI from the MP. Inside the Report tab I still see that same CI appear which is not ideal. You'd think clicking the three dots besides it lets me Delete it from the page, but to my surprise that option is greyed out. How do I get rid of this CI from the Report page?

How to run the profiling using GQL based on the Catalog Item Name and type of profiling

Hi Everyone ! I’m Srija ,Solutions Consultant here at ataccama. Today I’m sharing how to profile a catalog item using GraphQL by providing the Catalog item name and type of profiling. Profiling is usually performed to Catalog Items. There are two types of data profiling in AtaccamaOne. Sample Profiling Full ProfilingWe can do profiling using the Ataccama One Web GUI but there are limitations. Consider a scenario where profiling needs to be executed for multiple catalog items in one Go. In such cases, GraphQL can be leveraged within a plan to facilitate the profiling process. By specifyingthe catalog items and the type of profiling (Sample/Full), the profiling operation can be seamlessly performed.The below GraphQL Query helps to run the specified profiling for the specified Catalog Item. This can be executed in the playground/postman tool or can be done in a plan in ONE desktop. Here's the query structure:query ImportCatalog ($connection_id: GID!) {connection(gid: $connection_id) {i

Breaking Excel Sheet into multiple files

Hi everyone,I currently have a plan that is creating a main task and populating it with sub tasks that each link to individual tables. My issue at the moment is that sometimes this creates tasks with a huge amount of sub tasks that may seem daunting for people to try to work through.Currently the tables and their attribute ids are all stored in one excel sheet, so I was wondering if it would be possible to break it into separate excel files each containing 20 rows. If this is possible I would then be able to create additional tasks rather than just grouping everything in one.Thank you for any help!
