A database model is a type of data model that determines the logical structure of a database and fundamentally determines in which manner data can be stored, organized and manipulated. The most popular example of a database model is the relational model, which uses a table-based format.
Several years ago everyone got mad about BigData – nobody knew when smallish data will become BIGDATA, but all knows that it’s trendy and the way to go.
In the prior part of this series we have provided introduction to Google MapReduce approach, but still not covered their possible ObjectScript implementation. Which we will start to explain today.
In part I of this series we have introduced MapReduce as a generic concept, and in part II we started to approach Caché ObjectScript implementation via introducing abstract interfaces. Now we will try to provide more concrete examples of applications using MapReduce.
I've been building up a REST services API, consisting of a dozen or so classes referenced from a Dispatch class, which has route mappings for the first piece of the URI. I'd like to have the Dispatch class be able to output all of the available Services, with some documentation. Is there something like a %Library resource that I could use to pull this information from each of the classes?
I have been following the online Zen Quickstart Tutorial using the lastest release documentation. In addition to playing around with the styling and making a few minor functionality tweaks, I wanted to add an additional column that shows a count of the number of phone numbers for that Contact (as shown in the image below).
Process-private Globals can be used as a data global in storage definition. That way, each process can have its own objects for the class with ppg storage. For example lets define a pool, which can:
The field test of Caché 2016.2 has been available for quite some time and I would like to focus on one of the substantial features that is new in this version: the document data model. This model is a natural addition to the multiple ways we support for handling data including Objects, Tables and Multidimensional arrays. It makes the platform more flexible and suitable for even more use cases.
I am pleased to announce the next 2016.2 field test kit, 2016.2.0.605.0.
There are about a hundred changes from the previous field test kit, including the following fixes to problems found by those using the kits in the field:
I am pleased to announce the next 2016.2 field test kit, 2016.2.0.595.0.
It may look like a slow week, with less than fifty changes having been checked in, but this kit includes the following fixes to problems found by you, the ones running the kits in the field:
Is there someone that has developped a program in order to create a
"decisiontree"? Depending The answer to a question leads to another question, and so on,
and so on, and there is an option to return to another point in the decisiontree.
Best regards,
Simon.
p.s. I've already got something, but it's not workable. But to get an idea:
