NULL Valued fields on DQS

How are NULL’s considered? I have a case statement which gives the right value matching measure -used debug to test. But when it comes to matching rules, it skips the rule. Example:Name      NPIRamona  12345678NULL       12345678the 2nd row should match the 1st on NPI value and considering on of them is null.Even the scenarioName      NPINULL       12345678NULL       12345678these two should match together based on NPI. I do not see a special character. If I replace NULL with a value ‘A’ , they match with rule Matching on NPI. but does not work for NULL.  Any thoughts or suggestions appreciated.

Results message not showing as message.

Hello, I’ve got a question while using DQ evaluation rules.I have been creating rules with valid and invalid messages but just the invalid message at the end does not display as intended. But when I view this in the results tab it just says OTHER as the explanation.    Is there a workaround to this problem? Should I edit my rule logic to include some specific condition and leave the rest to fall under the ‘IF none of the conditions above apply THEN’ TIA for the replies.

Data Quality and Pipeline Execution
Data Quality and Pipeline ExecutionBest Practice

Hello, here is a short video to illustrate how an organization might use Ataccama Data Quality to run checks as part of an existing data pipeline, and verify data integrity before further processing. With Ataccama, you can use various data warehouses or ETL tools, and GraphQL API integration allows conditional scheduling and more complex orchestration.In this demonstration, we use DataBricks Notebook to trigger DQ execution and retrieve the results. These determine whether to halt or commence the pipeline, and in-app dashboards display the metrics. All results and metadata can also be exported to a data mart table for further analysis and visualization.The platform is designed to provide visible and usable data quality insights, and we offer flexible integration capabilities to suit any data stack. Thanks for watching.

Adding a New Entity in MMM ModelBest Practice

METADATA MODELThe metadata model is used to configure the application entities and their properties. The Metadata Model describes the entities and their properties in the application.  Web Application) use the Metadata Model to create the frontend user interface. The metadata model is also responsible for the configuration of the left navigation menu of the application.ONE METADATA PROPERTY REFERENCESEntities consist of properties of Simple types, such as strings and integers, and Object types, which link the entity to other entities.ADDING NEW ENTITY TO MMM MODELIf you are creating an entity using the user interface, you must then add it as a property of the root entity metadata and then publishFor example, if we need to add a new entity under Business Glossary named (TestEntity) to the MMM modelClick on the Global settings on the left panelChoose Metadata Model under Maintenance CenterWe must create a new entity under Term so click on create entityFill in the name of the Entity, and

Extracting data quality results- deatiled failed records

Hi,We are using Ataccama one 12.6 version. We have a project containing 40+ models with 90 + rules. I am looking for an options to get the detailed invalid/failed records for each model. Like all the attributes from the model along with invalid rule instance names.The idea is to get the whole failed dataset to automate the remediation process. We already have automated process to remediate the data using other technologies.I don’t want to use the download results in csv option, because we are transitioning to latest version of Ataccama.I am looking for couple of optionsExtract the detailed failed records from backend tables using sqls (where Ataccama stores the results) or would like to understand how those csv files are generated in backend and use the same way to get the data and store in  db. Reading data through Ataccama inbuilt API’s and loading into a db. I am  going through the GraphQL options. Could you please let me know, If there is way to get the similar data through GraphQL

DQC match - slow incremental load

The matching component is slow at the extended unifications step for a incremental load. When a record like ‘WALGREEN%’ is loaded and there are 20K records with similar name on the instance, the records are all considered through the process of matching. Hence the process is slow when processing the increment and even if the incremental load has 11 records to process 30K records have the transaction Id and omni_modified date updated with the work order related on the instance table.  When I check history, nothing changes on these records except the omni_modified_date and transaction_id to that of the work order. Tweaking the union keys to create combination of name and key factors or adding separate groups for the high count records is not helping. Any thoughts or suggestions?

Integrating Ataccama with JiraBest Practice

Imagine the scenario where you have Ataccama ONE Data Quality Monitoring Projects running regularly. Any Data Quality (DQ) issues are already exported to our DQ Issue Tracker (DQIT) module. You can also see trends of DQ over time within the Ataccama ONE Web application.You start noticing that the score for some DQ rules has had a sharp drop in quality, and you want someone to investigate this.One of our customers decided that they want to integrate Ataccama with Jira at this point. Have Ataccama raise a ticket into Jira when this happens automatically.In this article, we will explore:Preparing to integrate with Jira The Json Call stepPreparationsBusinessUnderstand your end users. What do they expect to see in their Jira ticket? Know which fields in the Jira ticket are mandatory Have an idea of what extra information you should supply in the detailed description of the ticket.

Re-usable published components

Hi,For our monitoring projects  post processing we use fairly standardized (sub-) components. Now for every MP / CI combination these sub-components are all the same. If an MP Postprocessing is published these components get published also, right?Is there a way to have a single version of a component stored?This would make maintenance and life-cycle-management on these components a lot easier. In stead of having to go in the PostProcessing main component, we'd just have to change one.A plausible solution would be to split things and do things asynchronously, maybe. But that is a more of a workaround.Any ideas?

Customize Business Glossary Term View

Hi,I’m trying to modify our view of our business terms - currently we have a lot of information showing in the default view that our end users may not care about.  What I really want to do is modify the view, so that it only shows Name, Abbreviation, Description and Synonym.  I have figured out how to add the columns, but I can’t figure out how to remove unwanted columns.  For reference here is the default screen layout in Ataccama One via the Debugging Tools. {"_type": "entity.page.listing","children": {"_type": "relationships.hierarchyListing","enableSelection": true,"columns": {"type": {"dataPath": [],"name": "Type","after": "name","renderer": {"_type": "glossary.termType.tableCell"}}}}}

Parse JSON value in (Databricks) SQLBest Practice

I’ve been working on a use case recently which I think may be of interest to the community here.Some reference data is stored in a single table DATA_KEY_ID column tells us what reference data set it is DATA_VAL column stores the actual reference data in the format of a json array Goal is to extract the values from the json array, and use it as a lookup item in Ataccama ONE, which in turn is used in Data Quality Validation rulesTo start with, you need to have some preview access to the data and understand the schema of the json. For the example in this post, I have very simple “id” and “name” properties for my json. You will need to analyse that data before starting this, so you know what to put into the Json parser, or which values you want to get out from the json object.  Solution 1: Virtual Catalog Item (VCI)Bring the reference data table into Ataccama ONE Build a VCI, with a Catalog Item Reader of the reference data table Use a filter step to filter the exact set I need (it will al

Data Quality and Integration Scenarios

IntroductionThis post was created to answer the following questions:When moving data through data pipelines, how can the Ataccama ONE DQ platform support Data Integration platforms other than its own. How do other Integration Platforms access the DQ rules? How do other Integration Platforms flag records for Data Stewards to review?DQ platform in context of integration processesThere are three key patterns that are typically used for integration of the ETL process with Data Quality:Option 1The integration platform calls Ataccama DQ rules exposed as real-time API, sending in batches or micro-batches of data for evaluation.Option 2The Integration platform loads data into a staging/landing layer and triggers (via API call) a batch process in Ataccama, Ataccama evaluates/improves the data and populates the cleansed layer in the data lake, including DQ scores and flags. Option 3Ataccama can be connected to a data stream, such as Kafka, and on the fly evaluating data in the stream - every mes
