What Happens. Inguinal hernias typically flatten or disappear when they are pushed gently back into place or when you lie down. Over time, hernias tend to increase in size as the abdominal muscle wall becomes weaker and more tissue bulges through. If you can't push your hernia back into your belly, it is incarcerated. A hernia gets incarcerated when tissue moves into the sac of the hernia and fills it up. This is not necessarily an emergency. But if a loop of the intestine is trapped very tightly in the hernia, the blood supply to that part of the intestine can be cut off (strangulated), causing tissue to die.
Schematron. An XML schema that is used to validate an XML document. Unlike grammar-based schema languages, Schematron is made up of XPath patterns that define the tree structures and relationships. It can be used by itself or embedded within a W3C XML Schema or RELAX NG schema. The final draft of an ISO version of Schematron was made available in late 2004 and was published as an ISO standard in 2006. For more information, visit www.schematron.com. See XML schema.
A database schema is a collection of metadata that describes the relations in a database. A schema is also described as the layout or blueprint of a database that outlines the way data is organized into tables. A schema is normally described using Structured Query Language (SQL) as a series of CREATE statements that may be used to replicate the schema in a new database. An easy way to envision a schema is to think of it as a box that holds tables, stored procedures, views and the rest of the database in its entirety.
