normalizing means heat the steel to above the AC3 or ACCM 30-50holding for some time,put out from the furnace,and cool in air or by water,spray,wind.Normalizing purpose is to reduces residual stress and brittleness.Author Tom RobertsonWhat is Normalizing? Definition,Process,Advantages,and The main purposes of the normalizing heat treatment on metals are To remove structural irregularities or impurities and defects from the metal.To improve ductility that has been lost in some metal processing.To reduce the hardness that has been increased byDatabase NormalizationField Of StudyOverviewNormalizationFirst Normal FormDenormalizationBoyce Codd Normal FormIntroductionObjectivesExample Defining RelationshipsDatabase normalization is the process of structuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity.It was first proposed by Edgar F.Codd as part of his relational model.Normalization entails organizing the columns and tables of a database to ensure that their dependencies are properly enforced by database integrity constraints.It is accomplisheSee more on en.wikipedia Text under CC-BY-SA licenseIf a database design is not perfect,it may contain anomalies,which are like a bad dream for any database administrator.Managing a database with anomalies is next to impossible.1.Update anomalies If data items are scattered and are not linked to each other properly,then it could lead to strange situations.For example,when we try to update one data item having its copies scattered over several places,a few instances get updated properly while a few others are left with old values.SuSee more on tutorialspointHere are the most commonly used normal forms 1.First normal form(1NF) 2.Second normal form(2NF) 3.Third normal form(3NF) 4.Boyce Codd normal form (BCNF)See more on beginnersbookThe following are disadvantages of normalization. You cannot start building the database before you know what the user needs. On Normalizing the relations to higher normal forms i.e.4NF,5NF the performance degrades. It is very time consuming and difficult process in normalizing relations of higher degree. Careless decomposition may leads to bad design of database which may leads to serious problems.See more on ecomputernotesSee moreNew content will be added above the current area of focus upon selectionSee lessThis article is an effort to provide fundamental details of database normalization.The concept of normalization is a vast subject and the scope of this article is to provide enough information to be able to understand the first three forms of database normalization.1.First Normal Form (1 NF) 2.Second Normal Form (2 NF) 3.Third Normal Form (3 NF) A database is considered third normal form if it meets the requirements of the first 3 normal forms.See more on sqlshackFor a relation to be in Third Normal Form,it must be in Second Normal form and the following must satisfy 1.No non-prime attribute is transitively dependent on prime key attribute.2.For any non-trivial functional dependency,X A,then either X is a superkey or,1.A is prime attribute.We find that in the above Student_detail relation,Stu_ID is the key and only prime key attribute.We find that City can be identified by Stu_ID as well as Zip itself.Neither Zip is a superkey nor is CSee more on tutorialspointA table is said to be in 2NF if both the following conditions hold 1.Table is in 1NF (First normal form) 2.No non-prime attribute is dependent on the proper subset of any candidate key of table.An attribute that is not part of any candidate key is known as non-prime attribute.Example Suppose a school wants to store the data of teachers and the subjects they teach.They create a table that looks like this Since a teacher can teach more than one subjects,the table can have multiple rows fSee more on beginnersbookTo be in third normal form,the relation must be in second normal form.Also all transitive dependencies must be removed; a non-key attribute may not be functionally dependent on another non-key attribute.See more on opentextbc.caSee moreNew content will be added above the current area of focus upon selectionSee lessAccording to WikipediaDenormalization is a strategy used on a previously-normalized database to increase performance.In computing,denormalization is the process of trying to improve the read performance of a database,at the expense of losing some write performance,by adding redundant copies of data or by grouping data.It is often motivated by performance or scalability in relational database software needing to carry out very large numbers of read operations.Denormalization shouldSee more on sqlshackDatabases intended for Online Transaction Processing (OLTP) are typically more normalized than databases intended for Online Analytical Processing (OLAP).OLTP Applications are characterized by a high volume of small transactions such as updating a sales record at a supermarket checkout counter.The expectation is that each transaction will leave the database in a consistent state.By contrast,databases intended for OLAP operations are primarily \read mostly\ databases.OLAP applications tenSee more on wiki.gisAfter reading about Normalization above and how things should be broken up,you may be thinking Well,now I have all these tables all over the place,and I have to join a buncha them just to get simple sets of data out of the system!
