In a professional database management system, tables and indexes can be split into two different types: horizontal and vertical. This separation of the two types of data structures is important for various reasons. More specifically, it helps to control the performance and security aspects of the database, while at the same time preventing information from being wrongly used in unintended ways.
However, since both types of data types have their own benefits and drawbacks, it is advisable to only select one or the other depending on the type of application you are using, as well as the other fundamental data types contained within the database. For example, if you are working with a larger number of fundamental data types, then you should use a horizontal index table because it will make life much easier for the developers, as well as create an overall better database management system.
To split up the data of the system so that horizontal index tables can be placed on top of vertical indexes, the overall layout of the database should first be analyzed. With that, it is best to make note of the logical structure of the database, which can help you when planning your database layout later on. There are three main types of logical structures that you should keep in mind when designing the database layout for your system.
– The open, foreign, and closed logical data structures. Open and foreign-looking names refer to data that is part of a table that is not necessarily part of another table. This type of data is also referred to as open recursion, since the statement of the database query will implicitly return the correct answer in every situation, even though there may be different tables involved. A closed loop is an example of the closed logical data structure.
– A blend of both horizontal index tables and vertical indexes. The blending of two different types of indexes will result in a loss of performance and security. A blending of the two types of indexes will be more appropriate in some cases, while it is not advisable in others. It is recommended that if you are able to perform the data-level blending without losing any significant amount of performance, then you should opt for that option.
It is usually advised that all indexes are checked and managed before the introduction of a new table. With this, the server is able to better manage the overall performance of the entire database.
Vertical indexes can also be subdivided into two types: the Inline and the Outline. Inline indexes are usually reserved for indexing the primary key and have the benefit of providing both read-write access and read-only access.
