Juan Navarro
The quarterly journal Informatica provides an international forum for high-quality original research and publishes papers on mathematical simulation and optimization, recognition and control, programming theory and systems, automation systems and elements. Informatica provides a multidisciplinary forum for scientists and engineers involved in research and design including experts who implement and manage information systems applications.
Informatica is published by the Vilnius University Institute of Data Science and Digital Technologies in cooperation with IOS Press. Informatica is an open access journal. The journal does not charge article processing charges or submission charges. For more information on the journal as well as online paper submission please consult the journal website.
KUDOS
Authors of published articles (non-prepress, final articles) will be contacted by Kudos. Kudos is a service that helps researchers maximize the impact and visibility of their research. It allows authors to enrich their articles with lay metadata, add links to related materials and promote their articles through the Kudos system to a wider public. Authors will receive no more than three emails: one invitation and a maximum of two reminders to register for the service and link the published article to their profile. Using and registering for Kudos remains entirely optional. For more information, please have a look at our authors section.
A fake version of journal has been created at the url www[.]informaticajournal[.]com. This is a scam attempt. Informatica is published by Vilnius University Press in cooperation with IOS Press. More information can be found here.
In the next few weeks, my company will be engaging multiple vendors to establish a choice for a common global ETL tool - not necessarily one that can't be broken from, but just where our license investment will go to consolidate those costs. Two of the major players are Talend and Informatica, with others that are unimportant for the sake of this question.
My experience is in Talend's Enterprise ETL tool, Talend Integration Suite, which also has many standard integration capabilities. Aside from all of the obvious pros and cons between the two such as cost, availability of knowledgeable resources, etc. my question is specific to the development language knowledge required.
I'd like some feedback on the Informatica option. I can state from experience that to use Talend effectively, and reach beyond it's pre-programmed bounds (which happens pretty often), you need to have a decent background in Java. And in this case, I mean Java directly - you can literally use Java if you need to add-on functionality, not a "special" version of Java. What is the situation with Informatica? Is there a particular extension language you can use? Is it proprietary, but perhaps closely related to a mainstream language? What is the likelihood of needing to use it for any jobs of consequence?
Informatica has its own transformation langugage that you can use in your expressions, filter and such. It is quite versatile and not at all difficult to learn, if you're familiar with any of the most popular programming languages of today. SQL is probably the one it resembles the most. You will definitely need to learn at least the basics of this langugage to be able to use Informatica efficiently.
It is also possible to create Java transformations, although those should be fairly rarely needed. Usually the built-in transformations combined with Informatica's own transformation language will provide more than enough options.
I have seen custom transformaions written in 'C'. For what it was used for, it really wasn't worth the effort. This answer suggests you can also use Java. A few years back, I saw that Perl was supported as an extension language, but I can find no such references today. They probably dropped support for that.
When you create mappings and create links between sources and targets and when you use the transformation, in each process informatica is generating or using SQL and SQL concepts. Hence thorough working knowledge of SQL is mandatory to work on Informatica PC.
Acta Universitatis Sapientiae Informatica publishes peer-reviewed, high-quality original papers and surveys in English, in all areas of Computer Science and allied fields. The papers must be self-contained, including the purpose of the research, the basic definitions, the antecedents of the research, the presentation of the state-of-the-art and novel contributions. The articles must contain sufficient references to give the reader a broad view of the studied subject.
The corresponding author is responsible for obtaining the permission of coauthors and of the authorities or institutions, if needed, for publication, the Editorial Board is disclaiming any responsibility.
The papers have to be prepared carefully, and must include the relevant keywords. References should be listed alphabetically based on the Instruction for Authors given at the address www.acta.sapientia.ro/acta-info/informatica-main.htm.
The editorial board is participating in a growing community of Similarity Check System's users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.
I have just seen talend 1 time, informatica I only know by name. Are there any experts here who can share their knowledge and tell me wgether KNIME could replace them even if it is not KNIMEs primary purpose? If so why / why not?
Thanks
