These features included the ability to define types and to fully describe relationships – something used widely, but maintained entirely by the user. In POSTGRES, the database understood relationships, and could retrieve information in related tables in a natural way using rules. POSTGRES used many of the ideas of Ingres, but not its code. [31]
In SQL, the TRUNCATE TABLE statement is a data manipulation language (DML) [1] operation that deletes all rows of a table without causing a triggered action. The result of this operation quickly removes all data from a table , typically bypassing a number of integrity enforcing mechanisms.
The adapter pattern describes glue code as a software design pattern. Glue code describes language bindings or foreign function interfaces such as the Java Native Interface (JNI). Glue code may be written to access existing libraries , map objects to a database using object-relational mapping , or integrate commercial off-the-shelf programs.
In electronics, glue logic is the custom logic circuitry used to interface a number of off-the-shelf integrated circuits. [1] This is often achieved using common, inexpensive 7400- or 4000-series components. In more complex cases, a programmable logic device like a CPLD or FPGA might be used. The falling price of programmable logic devices ...
According to PostgreSQL v.9 documentation, an SQL window function "performs a calculation across a set of table rows that are somehow related to the current row", in a way similar to aggregate functions. [7] The name recalls signal processing window functions. A window function call always contains an OVER clause.
Another example is the single space that separates a command from the arguments of that command (called ’’cs’’ in the formal MUMPS standard). If the argument is empty, the command is considered to be "argumentless" since the space separating the command from its argument is immediately followed by the space(s) separating this command ...
A computer using a command line interface may present a list of relevant commands with assigned short-cuts (digits, numbers or characters) on the screen. Entering the appropriate short-cut selects a menu item.
Short-grain glutinous rice from Japan Long-grain glutinous rice from Thailand Glutinous rice flour. Glutinous rice (Oryza sativa var. glutinosa; also called sticky rice, sweet rice or waxy rice) is a type of rice grown mainly in Southeast Asia and the northeastern regions of South Asia, which has opaque grains and very low amylose content and is especially sticky when cooked.
