An XML document that defines what can be in an XML document. A Schema definition is more specific than a DTD and provides much finer-grained control over the content that can exist in an XML document.
Rules stating what attributes may or must be contained in an entry, according to an entry type (objectClass). A schema entry lists all the attributes belonging to a one entry type.
A schema defines vocabularies, structure and rules by which each type of element within an information set are interrelated and stored for further processing.
Collection of database objects, including logical structures such as tables, views, sequences, stored procedures, synonyms, indexes, clusters, and database links. A schema has the name of the user who controls it. See Also: logical structures
A language-independent data model that describes the classes of all persistent objects maintained in a federated database.
The set of objects owned by a user account.
The collection of database objects that are owned by a particular user are referred to as that user’s schema. Every object in the database belongs to one and only one schema, and therefore, to one and only one user.
An XML specification for describing constraints and relationships in XML documents. In particular, schemas can define simple and complex data types, type derivation and inheritance, element occurrence constraints, and namespace-aware element and attribute declarations. Perhaps the most important feature of schemas is the addition of simple data types for parsed character data and attribute values. While nowhere near as robust as the datatyping in the Java programming language, the simple data types supported by XML schema are a significant improvement for application developers. Similar to DTDs, an XML document that complies with all rules of a schema to which it is attached is said to be valid with respect to that schema. Back
(pl., schemata) A document that describes an XML or RDF vocabulary. Any document which describes, in formal way, a language or parameters of a langauge. The RDF Schema
A system of representing a data model that defines the data's elements and attributes, and the relationship among elements.
A set of metadata elements representing the attributes of a resource. Each element will have a name and associated semantics.
In the Data Access Builder and the Persistence Builder, the representation of the database that will be mapped.
W3C XML Schema recommendations are still in Working Draft status. A Schema is a mechanism similar to a DTD for defining data types. Schema are closer to the notions of programming objects and database data types than DTD element definitions. The concept of Schema was introduced to the XML-family in order to overcome some of the limitations of DTD, and also to be somewhat simpler. However, the enterprise proved to be much more difficult than first envisaged, and the W3C Recommendation is now more than a year late as the proposed documents were referred back to the work groups.
The definition of the data fields in a database. Each schema represents a database on an AR System server. The AR System comes with several sample schemas and you can build as many additional schemas as needed.
Formal definition of data to be stored in an LDAP directory. The schema definition maintains consistency across implementations and establishes a means for interoperability. The schema defines the name, OID number, and date type for each attribute, and specifies whether attributes are required or optional. The schema also establishes how attributes are to be compared, and whether the attribute instance is expected to be unique or multi-valued.
Consists of a library, a journal, a journal receiver, an SQL catalog, and an optional data dictionary. A schema groups related objects and allows you to find the objects by name. Note: A schema is also commonly referred to as a collection.
A description of the current structure of tables and views in a data source. The schema describes what columns are in each table, the data type of each column, and the relationships between tables. See also referential integrity.
An XML schema describes the structure of data in an XML document. It is also known as an XML Schema Definition (XSD). It defines the elements, attributes, and their data types in an XML document.

All of the objects that encompass the design of a database, including tables, views, and indices.
An outline of your database showing the different areas of information (database tables) and the different pieces of information in each of those areas (database columns), and illustrating how the pieces relate to each other. Also called a data model.
A model which defines a document, including the structure, allowed values and more.
Defines the formal structure, attributes and relationship of data. In an XML context, this is an alternative to DTD offering more flexibility and functionality. (See DTD)
A term that describes the structure of XML instances and constrains what they can contain. Two types of schema are used to constrain XML: Document type definition (DTD) XML schema
The formal definition of the contents of a resource description.
The set of object class es and corresponding attributes that can be stored in a directory. Also specifies attribute data types and formats.
What data you store and how you organize it depends on the purpose of your database. The specific organization of a database is called a schema.
A stored pattern in the nervous system, e.g., for the recognition of visible objects or for the execution of a particular action.
Describes the structure of an XML document just as a DTD does. The difference is that Schema are themselves XML documents and they provide a bit more control over what constitutes a valid XML document than a DTD can provide. Schema are a recent innovation and so software that can use Schema are not as common as those that can use DTDs. This is changing and Microsoft's MSXML 4 can process XML Schemas.

b . Defines the structure, content and semantics of XML documents. Schemas address deficiencies in DTDs such as specifying data types. Schemas are XML documents themselves and can be processed by a standard parser. See: Document Type Definition (DTD) Links: W3C XML Schema
A database-inspired method for specifying constraints on XML documents using an XML-based language. Schemas address deficiencies in DTDs, such as the inability to put constraints on the kinds of data that can occur in a particular field (for example, all numeric). Since schemas are founded on XML, they are hierarchical, so it is easier to create an unambiguous specification, and possible to determine the scope over which a comment is meant to apply.
A collection of components and database objects under the control of a given database user. The schema has the same name as the user who owns it.
the defined layout for a specific business document using XML syntax.
The universe of objects that can be stored in the directory is defined in the schema. For each object class, the schema defines what attributes an instance of the class must have, what additional attributes it may have, and what object class can be a parent of the current object class. The Active Directory schema is implemented as a set of object class instances stored in the directory. This is very different than many directories which have a schema but store it as a text file read at startup. Storing the schema in the directory has many advantages. For example, user applications can read it to discover what objects and properties are available. The Active Directory schema can be updated dynamically. That is, an application can extend the schema with new attributes and classes and use the extensions immediately. Schema updates are accomplished by creating or modifying the schema objects stored in the directory. Like every object in the Active Directory, schema objects are protected by ACLs, so only authorized users may alter the schema.

a description of the structure and rules a document must satisfy for an XML document type. Includes the formal declaration of the elements that make up a document.
A collection of database objects that are owned by a single user and form a single namespace. A namespace is a set of objects that cannot have duplicate names. For example, two tables can have the same name only if they are in separate schemas, no two tables in the same schema can have the same name. In Transact-SQL, much of the functionality associated with schemas is implemented by database user IDs. In database tools, schema also refers to the catalog information that describes the objects in a schema or database. In Analysis Services, a schema is a description of multidimensional objects such as cubes and dimensions.
In Oracle, a collection of objects associated with the database.
A named collection of objects, such as tables, views, clusters, procedures, and packages, associated with a particular user.
Defines the structure of a database, including classes of data objects and the type of information that each data object can contain. When setting up Cisco Unity for use with Exchange 2000 or Exchange 2003, the Active Directory schema must be extended.
XML and GML schemas express shared vocabularies and allow machines to carry out rules made by people. They provide a means for defining the structure, content and semantics of XML and GML documents.
A description of the data represented within a database. The format of the description varies but includes a table layout for a relational database or an entity-relationship diagram.
File that describes the structure of an XML document. This file can be a DTD file or an XML Schema file.
The structure of a database, a collection of structured documents, or other data storage or transfer mechanism. A schema can expressed in a diagram form, such as UML or ERD, or in a text based form, such as XSD.
A formal specification of element names that indicates which elements are allowed in an XML document, and in what combinations. It also defines the structure of the document: which elements are child elements of others, the sequence in which the child elements can appear, and the number of child elements. It defines whether an element is empty or can include text. The schema can also define default values for attributes. A schema is functionally equivalent to a DTD, but is written in XML. A schema also provides for extended functionality such as data typing, inheritance, and presentation rules. Consequently, the new schema languages are far more powerful than DTDs.
An information model implemented in a database. A schema may be a logical schema, which will define, for example, tables, columns, and constraints, but which may not include any optimization. It may be a physical schema that includes optimization, for example, table clustering.
Those definitions which describe the concept of the data and the relationship between the various elements or components of the data. A collection of items forming part or all of a model [ISO 10303-11: 1994]. A definition of data structure [Dacom, 1985].

A description of the object classes and attributes stored in Active Directory. For each object class, the schema defines the attributes an object class must have, the additional attributes it may have, and the object class that can be its parent. The Active Directory schema can be updated dynamically. For example, an application can extend the schema with new attributes and classes and use the extensions immediately. Schema updates are accomplished by creating or modifying the schema objects stored in Active Directory. Like every object in Active Directory, schema objects have an access control list, so only authorized users may alter the schema. See also: Active Directory; attribute; object; parent object
A Zope 3 framework built on the Interface package that allows you to specify details about attributes of the object that implements the schema. This includes type information (string, integer, etc) as well as restrictions on what values may be set (maximum length, can be None, etc) which can be automatically validated. The schema framework allows you to specify this information in an object's interface. Schema information is used by several other Zope 3 systems, such as metadata (properties) and forms. The schema package lives in lib/python/Zope/Schema. (thanks to Martijn Faassen)
