Game Vault Download Link ((EXCLUSIVE))
Lain Lattin
Any easy and quick way to add this kind of links to the notes? Like some extension or settings. I used to drag-and-drop, but now they just add the files into the vault instead of creating the correct link. And drag-and-drop is cumbersome. (edit: you need to hold ctrl, if not it will create a copy in fault)
Sweet, looking forward to the book then! It makes me wonder, what the dbtvault team has used for inspiration (or in a more literal sense, where they found the SQL or to what degree they came up with the SQL themselves) for their implementation of all patterns.
A) a dep-key in the link denotes that the dep-key is a part of the relationship forever, like a code or degenerate dimension; this relationship (dept + vendor + brand) will never have the same dep-key between them. Likely the offshoot to describe that dep-key is a ref table.
B) a dep-key in the link does not participate in the generation of the link hash key
C) if the attributes associated with the dep-key change then would this be better to include that dep-key in a link-satellite as a dep-key to that parent link-hash-key? Advantage of this approach is that you reduce the number of joins needed to get the data out and the resolution to which applicable dep-key attributes are appropriate to the recorded relationship at that point in time is resolved. Less complex SQL to get that data out. This of course means the data from source is already embedded with that ref-content! If it is seperate then it should be loaded separately and only resolved upon query time.
I used the schematic provided for the LMG1210 evaluation board and modified it for my design. I'm running in to some issues though connecting to the Texas instruments altium vault for the footprints when I want to create my PCB. The footprints for all components that were originally on the schematic are unavailable due to "No connection to the vault".
Back in 2017 we introduced the link structure with an example of a Data Vault model in the banking industry. We showed how the model looks like when a link represents either a relationship or a transaction between two business objects. A link can also connect more than two hubs. Furthermore, there is a special case when a part of the hub references stored in a link can change without describing a different relation. This has a great impact on the link satellites. What is the alternative to the Driving Key implementation in Data Vault 2.0?
A relation or transaction is often identified by a combination of business keys in one source system. In Data Vault 2.0 this is modeled as a normal link connecting multiple hubs each containing a business key. A link also contains its own hash key, which is calculated over the combination of all parents business keys. So when the link connects four hubs and one business key changes, the new record will show a new link hash key. There is a problem when four business keys describe the relation, but only three of them identify it unique. We can not identify the business object by using only the hash key of the link. The problem is not a modeling error, but we have to identify the correct record in the related satellite when querying the data. In Data Vault 2.0 this is called a driving key. It is a consistent key in the relationship and often the primary key in the source system.
To sum up you will always have a new link hash key when a business key changes in a relation. The challenge is to identify the driving key, which is a unique business key (or a combination of business keys) for the relationship between the connected hubs. Sometimes you would have to add an additional attribute to get a unique identifier.
Because identifying the driving key of a relation can be a problem in some situations you can use an alternative solution to avoid the driving key. All changes and deletes are tracked using a counter attribute in the non-historized link table. It stores also the descriptive attributes and the link hash key is calculated over all attributes.
Note: If your organization previously utilized the custom Casebook Link (casebook_link__c) formula field on the Subject, Visit, Monitored Subject, or Monitored Visit page layouts, you should remove it, and replace it with the standard Casebook Link field (casebook_url__v).
By default, this setting is set to False (in other words, External ID matching is enabled). Vault uses the External (RTSM) ID field to link Subject records from CTMS to Subject records in EDC if the Subject records are not already linked via the Global ID field. If matching External (RTSM) ID fields are identified, Vault links the two Subject records and updates the CTMS Subject record with the Global ID from the EDC Subject record. This is useful in situations in which a Subject record was created in CTMS before being created in EDC, such as for pre-screening purposes. Going forward, Vault continues to update the CTMS Subject record based on changes to the EDC Subject record based on matching the Global ID fields.
When transferring subjects from CDMS, the Clinical Operations to CDMS Vault Connection will check whether the Subject is linked via the Global ID field. If the Subject is not linked, the connection will also try to match on an External ID, if this field is not empty. If a match is still not found, the connection will create a new Subject and link it using the Global ID field.
Tony's guide to the steps worked well. (I cannot beleive missed that because I moved de database myself not even a year ago...)
However, I have some difficulties accessing/exploring the mailbox. Could well be IIS related... (IIS5)
I can access and show the searchpage. But every search ends up in Failed to perform the search reques.
Also the url is NOT accessable from the vaultserver. It does work from the cloned dc, but the mailboxes cannot be searched. I do see the folders. But that's it.
When accessing from the vault Console it wants credentials. But no account has access. Er.. I don't need an exchange server do I?
I guess it's my bad. I only recovered vault\storage\mailboxstore01\MailboxStore1Ptn1\ the folders 2008 and 2009. I now have issues in the eventviewer:
Search reguest failed
Reason: The Altavista index is not open [0xc0041c64]
But i could eventually export to PST. I wanted the mail, and I got the mail. Thanx!
The key vault retrieval can be a performance problem. Reading from key vault takes several seconds. The Azure SLA only says it will take less than 5 seconds 99.9% of the time. It does not guarantee the average time, but from my experience and hearsay, the average is about 2 seconds.

So my business sponsors and senior architects have decided to build a data vault. We have already recognized and considered the benefits of changing course for our enterprise. We spent a lot of time considering the business benefits that a different approach to business intelligence would provide. Some of these business related benefits that we identified are:
Remember: a Hub is a collection of business keys. A link tracks the relationship between hubs, or potentially with other relationships (links). A satellite is the time sensitive collection of attributes related to either an only one hub or link.
Hubs are the containers for business keys. They are the most important facets of the data vault methodology. The more successfully one is able to identify business keys the less refining of the model will follow. Business keys can be identified using a multitude of strategies. Sometimes it is from interviewing business users, sometimes it is from reviewing data models (primary keys or unique keys), sometimes it is from metadata systems that have identified key important information, as well as other areas.
Links stores the intersection of business keys (HUBS). Links can be considered the glue that holds the data vault model together. These tables allow for the data model to elegantly change over time because they can come and go as required by the business. Links also allow for the model to be created quickly without worry about whether the relationship is one to many or many to many. In addition, the flexible nature of link tables provides the option to add or drop link tables as requirements change throughout the maintenance lifecycle of the data warehouse or as part of a data mining exercise.
Satellites add all the color and description to the business keys (hubs) and relationships (links) in the data vault environment. Satellites contain all the descriptive information, tracking change by start and end dates over time, to let one know the information in effect at any point in time. In the purest sense, satellites are time aware and therefore tracks change over time as its main function. Satellites are always directly related and are subordinate to a hub or a link. They provide context and definition to business key(s). A satellite record is added when a change is detected in the processing. In some cases, there may be multiple satellites pointing to one hub or one link. The reasons for doing this could be multiple sources, or rate of change, or by data type.
With this quick overview of the basics of the data vault model, I hope you can see the simplicity in the design as well as the pattern based loading process. As you can see, whether you have 1 on 10 hubs or links, they should all look structurally similar as well as load in a similar fashion. This drives down overall development and support costs when the Enterprise Data Warehouse is supported by a data vault. Also, designers and developers that are new to the concepts generally can be up and productive in short order.
