A formal description of the structure of a database: the names of the tables, the names of the columns of each table, and the type and other attributes of each column. (And similarly for the descriptive information of other database-like structures, such as XML files.)
A formula in the language of an axiomatic system, in which one or more schematic variables appear, which stand for any term or subformula of the system, which may or may not be required to satisfy certain conditions
An outline or image universally applicable to a general conception, under which it is likely to be presented to the mind
A Tamino schema is an XML document that describes a Tamino Doctype It defines the names of all the elements and attributes of the Doctype, the relationship between the elements, and how the data in the elements is to be indexed for retrieval The information specified in the schema is used to a) parse instances of the Doctype stored in the XML database and b) to compose an XML document in response to a retrieval request Tamino XML Database provides two tools for defining schemas: Tamino's own Schema Editor, and XML Authority from Software AG's partner Extensibility
{i} diagram, scheme, plan
A description of the structure given to a set of metadata elements
The structure of a database or a rowset A database schema describes its tables, their column sets and indexes; a rowset schema describes its column set
(plural: schemata) See axiom schema; tautology schema; theorem schema
A collection of logical structures of data, or schema objects A schema is owned by a database user and has the same name as that user
That part of the database definition that describes the entire content and structure of the database
File that describes the structure of an XML document This file can be a DTD file or an XML Schema file
The configuration of stored metadata Schema also refers to a particular language for describing the nature and particulars of the structure of stored metadata
A definition of data type and structure in database There are, for example, DTD and XML Schemas Related Item: Technologies > XML Schema
1) a description of a database It specifies (among other things) the relations, their attributes, and the domains of the attributes In some database systems, the join attributes are also specified as part of the schema
A database schema is a description of persistent classes BaBar uses C++ classes, which are defined in Data Definition Language (DLL) Files, having a ddl suffix A schema is stored persistently in a federation
The data definitions that comprise a database created with SQL data definition statements (tables, views, indexes, etc) The SQL CREATE SCHEMA statement lets you specify (in a single SQL statement) all data and privilege definitions for a new schema One can also add definitions to the schema later
The design for a relational database, including the complete definition of tables and the relationships between them
All of the objects that encompass the design of a database, including tables, views, and indices
The formal definition of all object classes, and the attributes that make up those object classes, that can be stored in the directory The Active Directory includes a default schema, which defines many object classes, such as users, groups, computers, domains, organizational units, and security policies The Active Directory schema is dynamically extensible; this means that you can modify the schema by defining new object types and their attributes and by defining new attributes for existing objects You can do this either with the Schema Manager snap-in tool included with Windows NT Server, or programmatically
A schema is the organization or structure for a database
Synonym: data catalog The name of the collection of metadata describing the structure and constraints of a database The terms schema and data catalog are used synonymously in different literature on database management systems to specify the location of the data describing the content and structure of a database Most common components include: entity and attribute names, the set of attribute types describing each entity type, the data type and domain for each attribute, inter-entity type relationships, cardinality constraints, data locations, associated indexes, and usage restrictions The contents of the schema are defined using the data definition language, DDL, of the data management system
an internal representation of the world; an organization of concepts and actions that can be revised by new information about the world
An outline or image universally applicable to a general conception, under which it is likely to be presented to the mind; as, five dots in a line are a schema of the number five; a preceding and succeeding event are a schema of cause and effect
A formal specification of element names that indicates which elements are allowed in an XML document, and in which combinations 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
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 schema is an outline of a plan or theory. a definite position in the schema of the economic process. = outline. schemas schemata a drawing or description of the main parts of something
The description of the structure and the rules a document must satisfy for an SGML or XML document type The Schema comprises the formal declaration of the elements that make up a document, their mutual coherence, meaning and documentation as drawn up for a document type (or document or information model) Additional to DTDs a Schema is more flexible and can also contain rules for content or data types like dates, numbers etc
A pattern of attribute values (possibly containing "don't care" values) within the attribute values of an individual Schema (plural Schemata) are used to identify the groups of attribute values that have high or low worth in the fitness of the individual The "order" of a schema is the number of non-don't-care positions specified, while the "defining length" is the distance between the furthest two non-don't-care positions
