Network+ Schema - the description of object types, or classes, and their required and optional attributes that are stored in an NOSs directory A schema is a conception… perceived across all the members of a class.
The schema is the physical arrangement of data. An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and c…ontent of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints.
The role of the external schema is to support user views of data and thus to provide programmers with easier data access
A database schema is an actual plan for a database system. Sub-schemas are separate divisions that are used to achieve the plan for the database system.
The schema is the physical arrangement of the data as it appears in the DBMS. The subschema is the logical view of the data as it appears to the application program.
The Active Directory schema defines the kinds of objects, the types of information about those objects, and the default security configuration for those objects that can be …stored in Active Directory. The Active Directory schema contains the formal definitions of all objects, such as users, computers, and printers that are stored in Active Directory. On domain controllers running either Windows 2000 or Windows Server 2003, there is only one schema for an entire forest. This way, all objects that are created in Active Directory conform to the same rules. The schema has two types of definitions: object classes and attributes. Object classes such as user, computer, and printer describe the possible directory objects that you can create. Each object class is a collection of attributes. Attributes are defined separately from object classes. Each attribute is defined only once and can be used in multiple object classes. For example, the Description attribute is used in many object classes, but is defined only once in the schema to ensure consistency.

XML Schema is an XML-based alternative to DTD.An XML schema describes the structure of an XML document.The XML Schema language is also referred to as XML Schema Definition (XS…D).An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself.

A subschema is the applications programmer's view of the data within the database pertinent to the specific application. A subschema has access to those areas, set types, reco…rd types, data items, and data aggregates of interest in the pertinent application to which it was designed. Naturally, a software system usually has more than one programmer assigned and includes more than one application. This means there are usually many different subschemas for each schema. The following are a few of the many reasons subschemas are used: 1 Subschemas provide different views of the data to the user and the programmer, who do not need to know all the data contained in the entire database. 2. Subschemas enhance security factors and prohibit data compromise. 3. Subschemas aid the DBA while assuring data integrity. Each data item included in the subschema will be assigned a location in the user working area (UWA).The UWA is conceptually a loading and unloading zone,where all data provided by the DBMS in response to a CALL for data is delivered. It is also where all data to be picked up by the DBMS must be placed. Schema Data Definition Language (DDL)The schema data definition language (DDL) is used for describing a database, which maybe shared by many programs written in many languages. This description is in terms of the names and characteristics of the data items, data aggregates, records, areas, and sets included in the database, and the relationships that exist and must be maintained between occurrences of those elements in the database.l Data item. A data item is an occurrence of the smallest unit of named data. It is represented in a database by a value.l Data aggregate.A data aggregate is an occurrence of a named collection of data items within a record. There are two kinds-vectors and repeating groups. A vector is a one-dimensional sequence of data items, all of which have identical characteristics. A repeating group is a collection of data that occurs a number of times within a record occurrence collection may consist of data items, vectors.repeating groups

A Document Type Definition (DTD) is a set of markup declarations that define a document type for an SGML-family markup language (SGML, XML, HTML). A DTD uses a terse formal sy…ntax that declares precisely which elements and references may appear where in the document of the particular type, and what the elements' contents and attributes are. A DTD can also declare entities which may be used in the instance document.
