A database schema is similar to a record in Pascal or a struct in C. It describes the data and its logical format.
A collection of meta-data that describes the relations in a database.
an XML document that describes the DLESE metadata framework in terms of structure, datatypes, number of field occurrences and controlled vocabularies.
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.
See attribute schema.
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.
See NDS schema.
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.
the view, or definition, or description of data.
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.
