Row
A row is one of the components of a table. In relational data bases, data is expressed in terms of two-dimensional
tables containing rows and columns.
Row identifier
The rows of a database table are uniquely identified. A user can manipulate a row using the row identifier fetched by
the single row SELECT statement or by using the FETCH statement.
Scalable log operation
Splits log environments into multiple log groups in the RDB system for definition.
Schema
A constituent element of a database. SymfoWARE/RDB performs data analysis using information analysis system
AA/BRMODELLING to create tables or view tables.
Schema definition
Logical structure definition that includes defining the base tables and view tables that constitute a database, the
column configuration of each table, and the attributes of each column. In addition, privileges, a procedure routine, and
triggers can be defined. This is called "schema definition"
Scope
When a table is accessed by use of a SQL statement for data manipulation, the access range can be limited. The
access range of is called the scope. The scope function limits the data manipulation range for each user by applying
or canceling the scope for the user who accesses the table.
Security
SymfoWARE/RDB assures security for resources such as schemas, tables, procedure routines, and database spaces.
Sequence
A function that generates a value unique within an entire system. A sequence can be specified in an SQL statement to
use the generated values primarily for creating primary key values in a table.
SEQUENTIAL structure
A storage structure of base tables in a SymfoWARE/RDB database. This storage structure is applied to base tables for
adding rows (records) in the order of data generation, as in a historical journal.
