A Complementary Query Language to Google’s Dart

Structured Data Query Languages

Dart is a new structured data programming language from Google. While unstructured data has become extremely useful, structured data is still extremely important because it keeps businesses running day in and day out. Programming languages still need to be coded by hand and most Google users are not programmers. To fill this large gap for most Google users who have no programming experience, a structured data query language would be very useful. Query languages operate by what data or information is wanted and not how to access or derive it. No programming is necessary to use. This is very similar to a standard Google request. This allows anyone to specify a powerful structured data query request.

How does a query request automatically operate without being instructed on how to perform the request? This is done by analyzing the semantics in the data structure. Since query languages have the ability to search out meaning, they can derive the most value out of the semantics in the data structure. The first and primary place to look for semantics is in the data structure and should not be ignored even if other types of semantics are available. This is because the data structure drives or guides the meaning of the query.

Structured data often involves hierarchical structures. Hierarchical data structures inherently have a significant amount of structure semantics. Besides having vertical semantics they have horizontal semantics where data across pathways are related. This produces very complex structures requiring complicated data structure user navigation for programming languages. Query languages on the other hand are free to perform the navigation internally without involving the user. In fact, some complex data structures are too complex to handle with user navigation within programming languages. This makes query languages indispensable in these complicated situations proving query languages unique usefulness in structured data processing. One such complex data structure processing requiring query processing are multipath queries. These require complicated coordination between multiple paths of a hierarchical data structure such as when a query selects data from one path based on data from another path.

An amazing thing happened unnoticed and unplanned in the ANSI SQL-92 standard. In this standard, the LEFT Outer Join was introduced along with other outer join capabilities. The LEFT Outer Join is a one-sided join that is hierarchical by nature. It always preserves the left side of the outer join operation allowing, for example, employee data that has no dependent data to always be preserved. A new ON clause operation allows specification of hierarchical join criteria at each join point to replace the single use SQL WHERE clause. This prevents any ambiguity in defining hierarchical data structures that occurred when using the older WHERE clause. This combination of new SQL features unexpectedly turned out to support complete hierarchical multipath data structure definition and hierarchical processing even though there was no prior design performed or coding added in ANSI SQL to support full hierarchical processing.

These powerful hierarchical data structures can also be naturally defined in SQL views which can be dynamically joined in multiple ways creating larger variable structures and perform their hierarchical processing on the fly. This concept for processing dynamically created structured data is new and opens up many powerful capabilities in structured data. It utilizes a new Dynamic Metadata Maintenance operation that allows the metadata to be transparently processed. This eliminates any metadata operation by the user to process dynamic structured data. The ANSI SQL query language is in a position to take advantage of these new dynamic structured data capabilities such as for use in peer-to-peer data collaboration.

As stated in the very beginning of this article, Dart is a programming language. This gives it great user control that requires the user to have programming experience and knowledge. But what is not generally recognized, is that some problems are just too complicated to solve under user control. They require automatic processing to handle. These can be performed by a query processor. This automatic processing also means that the user does not need programming experience to specify the query. ANSI SQL's natural hierarchical structured data processing described above places it in a good position to be a complementary language for Google's Dart processor because each has their strong and weak points. Documentation describing the technology used by ANSI SQL hierarchical structured data processing follows:

Michael M. David is founder and CTO of Advanced Data Access Technologies, Inc. He has been a staff scientist and lead XML architect for NCR/Teradata and their representative to the SQLX Group. He has researched, designed and developed commercial query languages for heterogeneous hierarchical and relational databases for over twenty years. He has authored the book "Advanced ANSI SQL Data Modeling and Structure Processing" Published by Artech House Publishers and many papers and articles on database topics. His research and findings have shown that Hierarchical Data Processing is a subset of Relational Processing and how to utilize this advanced inherent capability in ANSI SQL. Additionally, his research has shown that advanced multipath (LCA) processing is also naturally supported and performed automatically in ANSI SQL, and advanced hierarchical processing operations are also possible. These advanced capabilities can be performed and explained in the ANSI SQL Transparent XML Hierarchical Processor at his site at: www.adatinc.com/demo.html.

Let's just nip the conflation of these terms in the bud, shall we?

"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.

They are not.

One is about the application. The other, the network. T...

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...

Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote arrangements of pop music, so the band could keep the crowd entertained during Friday night football games. What struck me then was that, to write parts for all the instruments - brass, woodwind, percussion, even k...

Node.js and io.js are increasingly being used to run JavaScript on the server side for many types of applications, such as websites, real-time messaging and controllers for small devices with limited resources. For DevOps it is crucial to monitor the whole application stack and Node.js is rapidly becoming an important part of the stack in many organizations. Sematext has historically had a strong support for monitoring big data applications such as Elastic (aka Elasticsearch), Cassandra, Solr, S...
There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure.
Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...
