These Guidelines as published in SmartAccess, suggest that all objects should have a descriptive tag, placed at the start of the object name Naming Conventions for Database Objects It is possible to run test cases against a production server. While it may seem desirable to identify views purely by their name – this is actually counter productive. Naming Conventions is an important factors for any type of database design. For example, if we have a column named OccupationID in a table named Employment, then we want to enforce two assumptions: Now you can drop and re-create all your foreign key constraints with just two lines of T-SQL, and know for certain that all your referential integrity rules are in place. This is a wrapper around SQL Server’s system tables: Paired with this, you'll need a view that tells you what foreign key constraints should exist in the database, based on the table and column naming conventions: The IsEnforced column tells you whether or not a physical constraint exists in the database, and the UniqueName column tells you what the name of that constraint ought to be - regardless of whether or not the constraint actually exists in the database. The first letter of the table name should be capitalized. A column that is intended to be a foreign key reference on another table follows this naming convention: AttributeEntityID.

Before delving … What can I say, except that they come from background of experience in which a lot of blood, sweat, and tears has been shed. The convention I describe here suits me, as a developer. There are coding standards on each programming language but in terms of MySQL I haven’t found any universal coding practice that everyone follows so i looked into different open source framework and popular PHP based software and found some generally applied standards on naming so I am trying to summaries it in this article. This shows the number of foreign keys in the dependency between two subsystems, and this gives you a sense of its 'weight'. In this section, I'll describe the steps to arrive at a solution that enables a DBA or a developer to query the schema for foreign key constraints that should exist - and to create those constraints automatically. There is a sample standard in the ‘Naming principles’ document (ISO/IEC 11179-5), but this is merely an example of how a standard should be defined. Database Object Naming Conventions: The Leszynski/Reddick Guidelines for Microsoft Access is the most commonly used naming convention for Access objects. Consistently applying a convention for naming tables, queries, forms, reports, and the control objects in forms and reports, across all Access databases makes their creation and maintenance much easier than if you use any old names. Naming conventions naming conventions that follow the rules in this Design Tip. Nice article. While several facets of naming an object deserve consideration, in this article we’ll focus on the most important one: defining a convention and sticking to it. That is the focus of the next article, which I will post here soon. When designing a database it's a good idea to follow some sort of naming convention. The focus here is on the database layer exclusively. That last bit is crucial. This integrated aspect allows IBM i users to directly access DB2 for i databases with their operating system user profile and the asso… So you won't find any C# discussed here; there is no Entity Framework, no data access layer, no unit tests, and no user interface. A few weeks ago, I posted an article titled "Lightning-Fast Access Control Lists in C#", in which I described a solution for storing and querying permissions in a way that is database-schema agnostic. This article, along with any associated source code and files, is licensed under The Code Project Open License (CPOL), General    News    Suggestion    Question    Bug    Answer    Joke    Praise    Rant    Admin.
