There are many different types of indexing, some of which require specialised skills from indexers. Examples include: Bibliographic and database indexing. Genealogical indexing. Geographical indexing. Book indexing. Legal indexing. Periodical and newspaper indexing. Methods of Indexing A typical method is to type a value in each field and press the Tab or Enter key to move to Index values may automatically appear in some fields without you typing anything. Instead of typing a value, you may choose one from a pick-list that appears. Separator sheets may Types or Methods of Indexing office files. 1. Book Index. The other name of book index is page index and ordinary index. The names of customers or documents or other information are entered 2. Vowel Index. 3. Bound Book Index. 4. Loose Leaf Index. For this reason, it is the indexing method that I personally favour – also because its combination of broad-brush and nitty-gritty approach fits my temperament. This is the method best suited to impatient perfectionists. Mark-up method. The mark-up method involves entering indexing tags in the book file itself. DBMS - Indexing. Dense Index. In dense index, there is an index record for every search key value in the database. This makes searching faster but requires more Sparse Index. Multilevel Index. B + Tree. The indexing has various attributes: Access Types: This refers to the type of access such as value based search, range access, etc. Access Time: It refers to the time needed to find particular data element or set of elements. Insertion Time: It refers to the time taken to find the appropriate Indexing in DBMS. Indexing is used to optimize the performance of a database by minimizing the number of disk accesses required when a query is processed. The index is a type of data structure. It is used to locate and access the data in a database table quickly.

Clustering index is
In its simplest definition a clustered index is an index that stores the actual data and a non-clustered index is just a pointer to the data. A table can only have one Clustered index and up to 999 Non-Clustered Indexes (depending on SQL version). If a table does not have a clustered index it is referred to as a Heap.
Various styles of indexing used in printed publications such as Index Medicus, the Engineering Index, and Chemical Abstracts are illustrated in the text; although the author is quick to note that printed tools are used much less today in favor of their online counterparts. In the online world, indexing has even greater importance in the effort to retrieve relevant data efficiently. Indexing has become an innovation-driven science, and investor acceptance of new concepts has fueled a "great debate" about which indexing methods will produce superior performance over time. In its simplest definition a clustered index is an index that stores the actual data and a non-clustered index is just a pointer to the data. A table can only have one Clustered index and up to 999 Non-Clustered Indexes (depending on SQL version). If a table does not have a clustered index it is referred to as a Heap. There are three main types of indexes: price-weighted, value-weighted, and pure unweighted. In business, different groups of variables in the measurement of which index number techniques are commonly used are (i) price, (ii) quantity, (iii) value and (iv) business activity. Thus, we have an index of wholesale prices, index of consumer prices, index of industrial output, index of value of exports and index of business activity, etc.
