Horizontal index tables are tables that can be used to keep track of the positions of the data. They are useful if you have lots of records with many different fields, as each field can only be entered once.
One can use this table to build an index on any table. So, an entry made in a horizontal index table can be seen by all users of the table. It is also ideal for searching and sorting the data in a manner that does not affect the general structure of the table. Such a search can be done by cross referencing the values in different columns.
In the world of database, there are two types of indexes, namely the primary index and the secondary index. Primary index is the index on a particular column. The primary index keeps the information of all the users in the table. Secondary index, on the other hand, helps the user to search the data. A primary index cannot have a secondary index.
If the primary index was to be put into the secondary index, it would make the database very complicated and inefficient. The best way is to put the primary index into the secondary index. This will create two primary indexes instead of one.
But a secondary index is an essential part of a full-text index. It is also used to track the relationships between two or more tables. The index can be created by another index.
Certain indexes are based on the time-to-first or the time-to-last timings. These timings help to reduce the overhead on the database server.
The advantage of a horizontal index table is that, it will hold all the records that are used in every query and as a result, it is quicker to access than the traditional “index and select” method. This makes indexing and searching easier and faster.
Creating indexes in a relational database can be done easily by using the SQL language. But if you are using a more complex tool such as Oracle, it is imperative that you add the full-text indexes manually.
