SQL Joins clause

SQL Join Types:

There are different types of joins available in SQL:
  • INNER JOIN: returns rows when there is a match in both tables.
  • LEFT JOIN: returns all rows from the left table, even if there are no matches in the right table.
  • RIGHT JOIN: returns all rows from the right table, even if there are no matches in the left table.
  • FULL JOIN: returns rows when there is a match in one of the tables.
  • SELF JOIN: is used to join a table to itself as if the table were two tables, temporarily renaming at least one table in the SQL statement.
  • CARTESIAN JOIN: returns the Cartesian product of the sets of records from the two or more joined tables.

Data Dissemination and Broadcasting Systems: Classification of Data-Delivery Mechanisms: ·          Push-based mechanisms (publish–subscribe mode) ·          Pull-based mechanisms (on-demand mode) ·          Hybrid mechanisms (hybrid mod                        Push-based Mechanisms: ·          Server pushes data records from a set of distributed computing systems ·          Examples of distributed computing systems advertisers or generators of traffic congestion, weather reports, stock quotes, and news report A server or computing system pushing the data records from a set of distributed systems : Publish–subscribe mode • In which the data pushed as per the subscription for a push service by a user Pushing Algorithm: Select a structure of data records to be pushed • An algorithm provides an adaptable multi-level mechanism that permits data items to be pushed uniformly or none uniformly after structuring them according to their relative impor

Client Server Computing with Adaptation

Image
Client Server Computing with Adaptation • Two adapters (adaptation software) at a mobile device • An adapter for standard data format for synchronization at the mobile-device • Another adapter for the backend database copy, which is in a different data format for the API at the mobile-device Adaptation: Software to get data in one format or data governed by one protocol and convert it to another format or to data governed by another protocol ·          Used for interchange between standard data formats and data formats for the API ·          IBM WebSphere Everyplace Access (WEA) provides adapters for synchronization objects (for example, XML format synchronization objects) and the objects of API databases (for example, for the PIM APIs)

Data Dissemination Broadcast-disk Models

Image
Data Dissemination Broadcast-disk Models: ·          Presumed that all the n records to be broadcast are stored on a circular disk from 0° to 360° ·          A hypothetical disk revolves and the angle changes from 0°to 360° ·          The entire N bits in n records get pushed through a hypothetical reading-head over the disk. ·          The head continuously reads each bit of a record just beneath it and broadcasts it instantaneously on the wireless network ·          During next revolution each bit in the records positioned from 0° to 360° broadcast once again in the same sequence as in earlier revolution Number of adaptations and algorithms for broadcast: 1. Circular Multi-disk Model 2. Flat Disk Model 3. Multi-disk Model with repetition rate proportional to priority 4. Skewed disk model Circular multi-disk model • Each block of records pushed with a repetition rate proportional to its hierarchical level Each rotating disk cycle:
