IBM System/360 Operating System Multiprogramming with a Fixed Number of Tasks (MFT) is an example of static partitioning, and Multiprogramming with a Variable Number of Tasks (MVT) is an example of dynamic. MVT and successors use the term region to distinguish dynamic partitions from static ones in other systems. [2]
Horizontal partitioning splits one or more tables by row, usually within a single instance of a schema and a database server. It may offer an advantage by reducing index size (and thus search effort) provided that there is some obvious, robust, implicit way to identify in which partition a particular row will be found, without first needing to search the index, e.g., the classic example of the ...
OS/360 MFT (Multiprogramming with a Fixed number of Tasks) [1] provides multiprogramming: several memory partitions, each of a fixed size, are set up when the operating system is installed and when the operator redefines them. For example, there could be a small partition, two medium partitions, and a large partition.
In MUMPS terms, "Color" is the 2nd subscript of the variable ^Car (both the names of the child-nodes and the child-nodes themselves are likewise called subscripts). Hierarchical variables are similar to objects with properties in many object-oriented languages. Additionally, the MUMPS language design requires that all subscripts of variables ...
For example, all rows where the column Country is either Iceland, Norway, Sweden, Finland or Denmark could build a partition for the Nordic countries. Composite partitioning : allows for certain combinations of the above partitioning schemes, by for example first applying a range partitioning and then a hash partitioning.
The SQL standard defines embedding of SQL as embedded SQL and the language in which SQL queries are embedded is referred to as the host language. A popular host language is C. Host language C and embedded SQL, for example, is called Pro*C in Oracle and Sybase database management systems, ESQL/C in Informix , and ECPG in the PostgreSQL database ...

For example, one background process may be designed to accept incoming e-mails, sleeping most of the day but suddenly springing to life when an incoming e-mail arrives. An alternative background process could be designed to accept incoming requests for web pages hosted on the machine, waking up only when a request arrives to service it.
