The queryoptimizer is the component of a database management system that attempts to determine the most efficient way to execute a Information retrieval query . The optimizer considers the possible query plan s for a given input query, and attempts to determine which of those plans will be the most efficient. Cost based query optimizers assign an estimated cost to each possible query plan, and choose the plan with the smallest cost. Costs are used to estimate the runtime cost of evaluating the query ... query. Generally, the queryoptimizer cannot be accessed directly by users once queries are submitted to database server, and parsed by the parser, they are then passed to the queryoptimizer where optimization occurs. However, some database engines allow guiding the queryoptimizer with hint SQL hint s. Implementation Most query optimizers represent query plans as a Tree data structure tree of plan nodes .

A power optimizer is a DC to DC converter technology developed to maximize the energy harvest from solar photovoltaic or wind turbine systems. They do this by individually tuning the performance of the panel or wind turbine through maximum power point tracking , and optionally tuning the output to match the performance of the string inverter . Power optimizers are especially useful when the performance of the power generating components in a distributed system will vary widely, differences in equipment, shading of light or wind, or being installed facing different directions or widely separated locations. Power optimizers for solar applications, can be similar to microinverter s, in that both systems attempt to isolate individual panels in order to improve overall system performance. A microinverter essentially combines a power optimizer with a small inverter in a single case that is used on every panel, while the power optimizer leaves the inverter in a separate box and uses only one inverter for the entire array. The claimed advantage to this hybrid approach is lower overall system costs, avoiding the distribution of electronics. Description MPPT Most energy production or storage devices have a complex relationship between the power they produce, the load placed on them, and the efficiency of the delivery. A conventional battery, for instance, stores energy in chemical reactions in their electrolytes and plates.

When a Information retrieval query is submitted to the database, the queryoptimizer evaluates some of the different, correct possible plans for executing the query and returns what it considers the best alternative.

Query optimization is a function of many relational database management system s in which multiple query plan s for satisfying a query are examined and a good query plan is identified. This may or not be the absolute best strategy because there are many ways of doing plans. There is a trade off between the amount of time spent figuring out the best plan and the amount running the plan. Different qualities of database management systems have different ways of balancing these two. Cost based queryoptimizer s evaluate the resource footprint of various query plans and use this as the basis for plan selection. Typically the resources which are costed are CPU path length, amount of disk buffer space, disk storage service time, and interconnect usage between units of parallelism. The set of query plans examined is formed by examining possible access paths e.g., primary index access, secondary index access, full file scan and various relational table join techniques e.g., merge join, hash join, product join . The search space can become quite large depending on the complexity of the SQL query. There are two types of optimization. These consist of logical optimization which generates a sequence of relational algebra to solve the query. In addition there is physical optimization which is used to determine the means of carrying out each operation.

For example, list all employees with 3 to 5 years experience. Range queries are unusual because it is not generally known in advance how many entries a range query will return, or if it will return any at all. Many other queries, such as the top ten most senior employees, or the newest employee, can be done more efficiently because there is an upper bound to the number of results they will return.

unsourced date December 2007 In Computer Science , Query Throughput QthD is a measurement used to determine the performance of a database system . The throughput metric is a classical throughput measure characterizing the ability of the system to support a multi user workload in a balanced way. Background A number of query language query users S is chosen, each of which execute the full set of 17 queries in a different order Fact date February 2007 . In the background there is an update stream that runs a series of insert delete operations one pair for each query user . The choice of the number of users is at the discretion of the test sponsor. The throughput metric is computed as the total amount of work S× 17 , converted to hours from seconds 3600 seconds per hour , scaled by the database volume SF and divided by the total elapsed time T sub s sub required between the first query starting and the last query or update function completing. Therefore the complete formulation is math mathit QthD frac S times 17 times 3600 T s times mathit SF math Note that if the test sponsor chooses S 1 for the throughput test, for ease of benchmarking it is permissible to omit the throughput test and compute the throughput metric using timings obtained during the power test. Similarly, it is permissible to schedule the insert delete activity for the throughput test after all the queries complete.

Query by humming QbH is a music retrieval system that branches off the original classification systems of title, artist, composer, and genre. It normally applies to songs or other music with a distinct single theme or melody. The system involves taking a user hummed melody input Information retrieval query and comparing it to an existing database . The system then returns a ranked list of music closest to the input query. One example of this would be a system involving a portable media player with a built in microphone that allows for faster Search engine technology searching through Digital media media files. The MPEG 7 standard includes provisions for QbH music searches. Examples of QbH systems SoundHound and Midomi are the only commercially available query by humming services available online at Midomi.com or on the mobile app called SoundHound. Both are powered by the same backend and are capable of recognizing humming and singing as well as recorded tracks. For the singing and humming search, the searchable database is based on Midomi.com s user contributions.

Query by Example QBE is a database query language for relational database s. It was devised by Mosh M. Zloof at IBM Research during the mid 1970s, in parallel to the development of SQL . It is the first graphical query language, using visual tables where the user would enter commands, example elements and conditions. Many graphical front ends for databases use the ideas from QBE today. Originally limited only for the purpose of retrieving data, QBE was later extended to allow other operations, such as inserts, deletes and updates, as well as creation of temporary tables. The motivation behind QBE is that a parser can convert the user s actions into statements expressed in a database manipulation language, such as SQL . Behind the scenes, it is this statement that is actually executed. A suitably comprehensive front end can minimize the burden on the user to remember the finer details of SQL, and it is easier and more productive for end users and even programmers to select tables and columns by selecting them rather than typing in their names, In the context of information retrieval , QBE has a somewhat different meaning. The user can submit a document, or several documents, and ask ... relational database front ends, notably Microsoft Access, which implements Visual Query by Example ... a query language such as SQL .
