1. Iso Naming Convention For Documents

Contents. Intended purpose Organizations exchange data between computer systems precisely using technologies. Completed transactions are often transferred to separate and systems with structures designed to support data for analysis. A de facto standard model for data integration platforms is the (CWM). Data integration is often also solved as a problem of data, rather than metadata, with the use of so-called.

ISO/IEC 11179 claims that it is a standard for metadata-driven exchange of data in an heterogeneous environment, based on exact definitions of data. Structure of an ISO/IEC 11179 metadata registry The ISO/IEC 11179 model is a result of two principles of semantic theory, combined with basic principles of data modelling. The first principle from semantic theory is the thesaurus type relation between wider and more narrow (or specific) concepts, e.g. The wide concept 'income' has a relation to the more narrow concept 'net income'. The second principle from semantic theory is the relation between a concept and its representation, e.g., 'buy' and 'purchase' are the same concept although different terms are used. A basic principle of data modelling is the combination of an object class and a characteristic. For example, 'Person - hair color'.

When applied to data modelling, ISO/IEC 11179 combines a wide 'concept' with an 'object class' to form a more specific 'data element concept'. For example, the high-level concept 'income' is combined with the object class 'person' to form the data element concept 'net income of person'. Note that 'net income' is more specific than 'income'.

The different possible representations of a data element concept are then described with the use of one or more data elements. Differences in representation may be a result of the use of synonyms or different value domains in different data sets in a data holding. A value domain is the permitted range of values for a characteristic of an object class. An example of a value domain for 'sex of person' is 'M = Male, F = Female, U = Unknown'. The letters M, F and U are then the permitted values of sex of person in a particular data set. The data element concept 'monthly net income of person' may thus have one data element called 'monthly net income of individual by 100 dollar groupings' and one called 'monthly net income of person range 0-1000 dollars', etc., depending on the heterogeneity of representation that exists within the data holdings covered by one ISO/IEC 11179 registry. Note that these two examples have different terms for the object class (person/individual) and different value sets (a 0-1000 dollar range as opposed to 100 dollar groupings).

The result of this is a catalogue of sorts, in which related data element concepts are grouped by a high-level concept and an object class, and data elements grouped by a shared data element concept. Strictly speaking, this is not a hierarchy, even if it resembles one. ISO/IEC 11179 proper does not describe data as it is actually stored. It does not refer to the description of physical files, tables and columns.

The ISO/IEC 11179 constructs are 'semantic' as opposed to 'physical' or 'technical'. The standard has two main purposes: definition and exchange. The core object is the data element concept, since it defines a concept and, ideally, describes data independent of its representation in any one system, table, column or organisation. Structure of the ISO/IEC 11179 standard The standard consists of six parts:. ISO/IEC 11179-1:2015 Framework (referred to as ISO/IEC 11179-1).

ISO/IEC 11179-2:2005 Classification. ISO/IEC 11179-3:2013 Registry metamodel and basic attributes.

ISO/IEC 11179-4:2004 Formulation of data definitions. ISO/IEC 11179-5:2015 Naming and identification principles. ISO/IEC 11179-6:2015 Registration Part 1 explains the purpose of each part. Part 3 specifies the metamodel that defines the registry. The other parts specify various aspects of the use of the registry. An additional part, is currently under development. Overview of 11179 Data Element The is foundational concept in an ISO/IEC 11179 metadata registry.

The purpose of the registry is to maintain a semantically precise structure of data elements. Each Data element in an ISO/IEC 11179 metadata registry:. should be registered according to the Registration guidelines (11179-6). will be uniquely identified within the register (11179-5). should be named according to Naming and Identification Principles (11179-5) See. should be defined by the Formulation of Data Definitions rules (11179-4) See and. may be classified in a Classification Scheme (11179-2) See Data elements that store 'Codes' or enumerated values must also specify the semantics of each of the code values with precise definitions.

Adoption of 11179 Standards 's COTS Metadata Registry (MDR) product supports the ISO 11179 standard and continues to be sold and used for this purpose in both commercial and government applications (see Vendor Tools section below). While commercial adoption is increasing, the spread of ISO/IEC 11179 has been more successful in the public sector.

However, it is unclear the reason for this. ISO membership is open to organizations through their national bodies. Countries with public sector repositories across various industries include Australia, Canada, Germany, United States and the United Kingdom. The United Nations and the US Government refer to and use the 11179 standards.

11179 is strongly recommended on the U.S. Government's website. And is promoted by as a foundation of the. The Open Group is a and technology-neutral working to enable access to integrated information within and between enterprises based on and global. Extensions to the ISO/IEC 11179 standard Although the ISO/IEC 11179 metadata registry is 6-part standard comprising several hundreds of pages, the primary model is presented in Part-3 and depicted in UML diagrams to facilitate understanding, supported by normative text.

The eXtended Metadata Registry initiative, led by the US, explored the use of ontologies as the basis for MDR content in order to provide richer semantic framework than could be achieved by lexical and syntax naming conventions alone. The XMDR experimented with a prototype using OWL, RDF and SPARQL to prove the concept. The initiative resulted in Edition 3 of ISO/IEC 11179. The first part published is ISO/IEC 11179-3:2013. The primary extension in Edition 3 is the Concept Region, expanding the use of concepts to more components within the standard, and supporting registration of a Concept system for use within the registry. The standard also supports the use of externally defined concept systems.

Edition 3 versions of Parts 1, 5, and 6 were published in 2015. Part 2, Classifications, is subsumed by the Concept Region in Part 3, but is being updated to a Technical Report (TR) to provide guidance on the development of Classification Schemes. Part 4 describes principles for forming data definitions; an Edition 3 has not been proposed.

Does anyone follow these naming conventions? I am pretty new to SQL programming and i didnt start out with a punch card or ticker tape. Every time i have a post this -CELKO- guy complains about how i write my sql code, this is the most recent link below.

And usually it is already after the post has been answered, its like he trolls the forum because he has nothing better to do but complain about people not programming in this format. I am not striving to be a goober master of SQL code and was wondering if this guy annoys anyone else with these types of posts?

I understand that there needs to be industry standards and its necessary for code compliance and understanding. But honestly whats with this guy? 'follow ISO-11179 data element naming conventions and formatting rules. Temporal data should use ISO-8601 formats.' CREATE TABLE Personnel: Right.

It is a set, so you use a collective name. Columns are scalars and have the same name everywhere they are used in the schema (ideally, everywhere in the Universe). The format is is used. So we have employeeid (empid if the shorthand is clear), hiredate, etc where things like id, date, type, code, etc.

Are properties A role is used when the same data element is used two or more places in the name query; instructorempid and studentempid. Also, that bio that Hasham quoted is out of date: I have about 1200 publication/presentation credits and eight books now. And I have no dry wit; I am just mean to people in forums:) -CELKO- Books in Celko Series for Morgan-Kaufmann Publishing: Analytics and OLAP in SQL / Data and Databases: Concepts in Practice Data / Measurements and Standards in SQL SQL for Smarties / SQL Programming Style / SQL Puzzles and Answers / Thinking in Sets / Trees and Hierarchies in SQL.

First you try to respect other community members. Whatever you are saying is that you never try to find out who that guy Celko is.

Let me put something here so after reading it your starting to take this guy suggestion seriously. This guy Celko is Jeo Celko. Here are some of his achievements; Joe Celko Joe Celko is one of the most widely read of all writers about SQL, and was the winner of the DBMS Magazine Reader's Choice Award four consecutive years. He is an independent consultant living in Austin, TX. He has taught SQL in the US, UK, the Nordic countries, South America and Africa.

He served 10 years on ANSI/ISO SQL Standards Committee and contributed to the SQL-89 and SQL-92 Standards. He has written over 800 columns in the computer trade and academic press, mostly dealing with data and databases. He is the author of eight books on SQL for Morgan-Kaufmann, including the best selling SQL FOR SMARTIES. Joe is a well-known figure on Newsgroups and Forums, and he is famous for his his dry wit. He is also interested in Science Fiction.

And regarding your question. Yes every good developer tried to follow ISO standards. But since you are pretty new you will take ages to understand these things. Thanks, Hasham. CREATE TABLE Personnel: Right.

You shouldn't use the underline character ' as separator because its usage makes the code harder to read; therefore increasing the cost of development and the number of potential bugs. The fact that its use is mentionned in the ISO-11179 standard as an example is irelevant because any error should be corrected; even when it's part of an old standard. So the correct way of writing 'employeeid' should be either 'employeeId' (camel notation) or 'EmployeeId' (Pascal notation). The decision of using Employee, Employees or Personnel as the name of a table is also questionable. When you take a look only at the database schema, the use of the name Personnel seems to be the correct choice. However, if you take into account the possibility of using something the Entity Framework and its automatic generation of code, the usage of the singular Employee as the name of a table might be the best solution at the end.

Thanks, Hasham Celko's achievements gives him no right to treat people the way he does. I think SBolton's post was actually quite reserved and reasonable considering the childish way celko acts. To actually purchase his book after such treatment is crazy.:-). I feel really disappointed reading this from you. I think you never learned anything still arguing about naming conventions and best practices.

If you have few minutes, please read this thread carefully not just to read it, to get the knowledge out of it. Please comment me back whatever you think, look we are not here to advertise ourselves, we are helping other community member and want them to learn good practices which we have learnt over the course of our lives. I never wanted to hurt anyone else feelings, but sometimes people just don't understand this how much time guys like Naomi, Erland, Arbi, Hunchback, Tom, Dan, Celko, Hugo, Uri and other spent here to help community members to learn best practices. It is just their passion that drives them here to help. Please think about this. Thanks, Hasham.

That guy annoys a hell out of me too, to the point I am dreading the Supreme SQL master guru feedback. He even goes as far as talking about how not very polite some of my inquires are and I am not even mentioning how frustrated he seems to be because (I'm guessing) he picked up on the fact that English may not be my primary language. Yes, I'm a proud french speaker humbly looking from more experienced users' feedback and best practices. But certainly not the way he tends to go about it. I see the post is from 2011 and yes, 2 years later, that guy seems to be on a personal crusade against the hordes of 'non SQL perfect' developers around this forum.

But certainly not the way he tends to go about it. I see the post is from 2011 and yes, 2 years later, that guy seems to be on a personal crusade against the hordes of 'non SQL perfect' developers around this forum. Are you into Zen? After doing this for 30+ years, I had people expecting me to do their homework or their job for them. Before I got translations, Russians and Indians would actually write me to tell me they had stolen illegal downloads and wanted me to provide them with free support (REALLY!) When I went out of my way not to upset anyone, they never heard anything I tried to teach them or they would assume that they were doing it right. All they wanted is a fast kludge.

So I whack people with a and post references to ISO, ANSI, etc. Standards and give reasons for things I do. They actually look at the references! They read what was posted! And if you think I am rough, read the stories about Dijkstra's programming classes:) He did not suffer fools gladly.CELKO- Books in Celko Series for Morgan-Kaufmann Publishing: Analytics and OLAP in SQL / Data and Databases: Concepts in Practice Data / Measurements and Standards in SQL SQL for Smarties / SQL Programming Style / SQL Puzzles and Answers / Thinking in Sets / Trees and Hierarchies in SQL.
