Abstract

e-commerce businesses</figcaption></figure>Key takeawaysLooking at the tools that Raw Vault brings with it, we can easily draw out following benefits –Fully equipped to tackle business changes — Be it a change in the business keys or entity relationships, the isolation of the keys and relationships from the actual data around them makes such integrations hassle freeHandles large data volume and achieves parallelism — One satellite per source enables parallel processing which inturn means load distribution and faster load cycles. Satellites can also be distributed on the basis of change velocity that results in reduced data redundancy.Incremental data onboarding — Onboarding new sources and data points made easier. Data Vault’s design advocates pattern driven development that enables a quick time to business for new requirements.Fail early and rectify fast — With Data Vault, SMEs can identify problems in the source data/model much before reaching the Data Marts.<h1 id="e2c5">Beyond Raw Vault</h1>So far, we’ve spoken about the advantages of implementing the Raw Vault. But, does that mean it doesn’t bring challenges of its own?As a matter of fact, it does. A quick look at the model above and stakeholders often find themselves asking questions like “How do we proceed from here?”, “What about the performance coming out of Raw Vault?”, “Is there a standard for pulling data out of the Raw Vault?”, “Shouldn’t there be a Business Vault, and what does that entail?”These are all valid queries, especially when it comes to constructing a robust and scalable architecture for the organization’s data management strategy. Some of the answers can be found in Business Vault. We’ll take a quick look at how it helps the data flow from Raw Vault to the Marts and if it is even mandatory for a fully compliant Vault implementation.The business vault is an extension of a raw vault that applies selected business rules, de-normalizations, calculations & other query-assistance functions. Business vault too comes with a few standard data extraction approaches as detailed below –PIT tables — PIT tables specifically address the need for denormalization. Denormalization doesn’t just mean stitching together data that’s maintained independently in the source systems, but also getting back data points that were segregated into multiple objects by the virtue of Raw Vault. For example, in the investment sector, one may want to look at not just the basic details around an instrument that they have invested into but also the coupon attached to it, the factors that get

updated every 10th of the month and/or the ratings provided from various Credit Rating Agencies. On the other hand, denormalization between the Raw Vault objects for daily positions data, that pivots on the relationship between a portfolio and an instrument is inevitable. A PIT table can help tie the data together for a better 360 view of the entities as well as tie the relationship stored in links back to the driving datasets and ready for consumption in the Data Marts.Bridge tables — The concept of bridge tables has been there for a while and just like any typical scenario, these will be created to optimize joins across datasets that are expected to be used together frequently.Satellites with predefined calculations — Quite often, there are some transformations / calculations / aggregations that are a common requirement across multiple user groups and functions. Business vault would be the recommended place to achieve these transformations which makes it available to various data marts.All this being said, is Business Vault a mandatory hop? The answer is no. One can be fully compliant to DV 2.0 and still not have a business vault implemented. We can see that the requirement for a business vault pivots around the complex scenarios that may pop up during the warehouse implementation.<h1 id="0603">Conclusion</h1>To conclude, let us take a moment and look at the factors of Data Vault that may impact the decision making process. Data Vault offers flexibility, scalability, governance and agility. All this, topped with a pattern driven approach for Raw Vault development, inturn results in a high speed delivery. There are frameworks and tools that can fuel the velocity even further (Check out more on Astraa’s MDD framework success story <a href="https://astraa.com/recognition/astraa-revolutionizing-insurance-analytics-with-intelligent-data-solutions/">here</a>).However, we have also seen how data extraction from Raw Vault can be a complex task in itself and may require stakeholders to factor in the implementation of Business Vault during their time and cost estimation. Not to forget, an increased number of objects to be maintained and monitored is an obvious byproduct.These are all very important points to be considered before choosing Data Vault as the warehousing approach. Considering the size of the enterprises is a critical factor too. A small enterprise would be recommended against going through the complexity of a Vault implementation if they have fairly lesser functions/line of businesses.Hope this helps in getting a fair understanding of Data Vault 2.0 and help gauge the impact of it’s implementation.</article></body>

Comminution

We’re smashing this word to pieces

Today’s New York Times Spelling Bee letters:

I, M, N, O, T, U, and center C (all words must include C)

Merriam-Webster says…

Silly little dictionary! Don’t you know that comminution can’t possibly be a word if The New York Times says it ain’t?

For a complete list of rejected words, check out the Spelling Bee Master.

What’s your favorite dord* from today’s puzzle?

My Two Cents

People who play the Spelling Bee and my regular readers —all five of them — are likely familiar with the game’s primordial concept of pangram. The pangram is the word that can be made using all seven letters in the puzzle at least once. (You’re allowed to use letters as many times as you’d like.) And every puzzle has at least one pangram, although sometimes more can be formed.

I’m not telling you what today’s pangram is, but yesterday’s game had the following seven letters: E, H, N, P, T, Y, and center O (all words must include O)…

…and three pangrams! Can you figure them out? I’m going to reveal the answers, so if you want to try this on your own first, stop scrolling down.

Stop.

The three pangrams are:

Honeypot
Neophyte
Phenotype

Now, because you can rotate the center letter, each pangram yields seven different games. But the pangram or pangrams stay the same, as they contain all seven letters.

What’s special about pangrams? Well, in the scoring system the Spelling Bee uses, words that are four letters long are worth one point. And every word five letters or longer is worth the number of letters in points. So, a pangram is worth at least seven points. (The ones mentioned above are worth 8, 8, and 9 points, respectively.) But you also get 7 bonus points for them. Which means each pangram is worth at least 14 points.

And why am I spending my not-so-valuable time and wasting your valuable time explaining all this? Well, because today’s rejected word, comminution, is a pangram. Rejected pangrams are frustrating for Spelling Bee players, as finding those magic words is a big part of what the game is all about.

I selected comminution to write about only because it’s a pangram, and I wanted to vent. After all, who wants to spend a Friday evening writing (or reading) about geology and bone fractures?

Sticks and stones

Comminution, which is a method of reducing a solid material into much smaller solid materials, can occur naturally or be a man-made process. The mechanics involved include grinding, crushing, cutting, and even vibrating.

In geology, comminution is one of the collateral results of faults occurring in the Earth’s crust. In industry, it’s a key element in mineral processing, ceramics, and electronics, and is usually achieved through different types of crushers and mills.

Industrial comminution is a complex things that involves equations such as this one…

…and flowcharts like this one…

…and graphs like these:

Is this really how you want to spend your Friday night? Trying to figure out complicated data about an industrial process you hadn’t even heard about until a few minutes ago?

I don’t either. Plus, I already made my point about the Spelling Bee rejecting comminution, a pangram worth 18 points.

Bones

In the human body, comminution is bad news. Like, really, really bad news. And that’s because it’s a type of bone fracture. One of the really, really bad ones.

Bone fractures can be classified according to several categories. For example, one category is cause: traumatic (due to a fall, a fight, or a car accident), pathological (due to bone weakness, as in osteoporosis), or periprosthetic (due to a mechanical problem with an implant, for example).

One of the other fracture categories is fragmentation, which includes the following types:

Incomplete: the bone fragments are still joined, at least partially; these are often seen as cracks in the X-ray..
Complete: bone fragments separate completely along the fracture line.
Comminuted: the bone has broken into several pieces. The more pieces involved, and the smaller they are, the more complicated and longer it will take the bone to heal.

Above are comminuted fractures of two digits. I’m not sure if they are fingers or toes. Taking into account that these type of bone destruction happens due to massive crushing, I’d place my bet on toes.

Remember all those Saturday morning cartoons, with pianos often falling on people’s heads?

Unfortunately humans are not toon characters, so we can’t bounce back like we’re made out of rubber. Well, okay, except for hockey players. They are freaks of nature.

Anyway, if you ever did survive a piano falling on top of you, or if the piano fell only on a part of your body, the bones in that part of your body would likely end up with a severe comminution.

So please be watchful of falling musical instruments next time you’re happily strolling down a sidewalk, minding your own business.

That’s about it for today. Thank you for scrolling all the way down. As a reward, here is the video of a song called “Comminution”, featuring cars, guns, and a very odd relationship. But seemingly… no actual comminution.

Now you know. Next time you think you’ve broken a bone and go to the hospital for an X-ray, ask the attending doctor if you have a comminuted fracture. Don’t be surprised if they act dismissive. Not because what you have is just a harmless sprain… but because the editors of the Spelling Bee decided that comminution is a dord*.
