How to Create Basic Index for your Stack Overflow Public Database

In this article we learn about the basic differences in clustered and nonclustered indexes, and how and why you should use nonclustered, basic indexes for stack overflow public databases

Basic Indexing For Stack Overflow Public DatabaseStack Overflow Public databases are those which have clustered indexes for all tables. It does not allow for nonclustered or full text databases, and does not even allow the user to store data from any stack site except Stackocerflow.com. One of the main reasons why you should have indexes in your database is because it makes locating data easier. And in an application like SQL Server, which contains massive amounts of data, indexing becomes all the more important. But what happens when you are using Stack Overflow public database that only allows you to have clustered indexed and not nonclustered indexes?

In such a situation, you can opt for creating basic indexes for your Stack overflow database. You might also continue using the clustered indexes that are available by default, but in certain situations, finding data from clustered indexes ends up being more complicated, as compared to finding data through nonclustered indexes. A clustered index will give you details of all fields in table, whereas a nonclustered index won’t. Therefore, if you wish to have indexes, that do not provide you with all the details at ones, you should opt for creating basic indexes.

Creating Basic Indexes

While working on creating indexes for Stack Overflow public databases, you can start with creating indexes for relationships between foreign keys. Creating indexes is one of the technical and complicated task, so do not undertake it if you are not sure about how to go about it.

  • One of the very first things you need to do when creating indexes is to outline the database schema.
  • Once that is done, you need to select the fields using which you want to index. Select the field type, Char, Varchar or Nvarchar.
  • For creating the index, type ‘/* Create relational indexes for Stack Overflow */’

USE StackOverflow;
Go
CREATE INDEX IX_field ON dbo.Badges(field)

Clustered and Nonclustered Indexes

Stack Overflow Public DatabaseWhen you create a non clustered index for a given table, there is a possibility that it might just end up occupying more space than a clustered table. But depending upon the kind of fields you have used, a clustered table is the one that is heavier and occupies more disk space than a non clustered table. One of the most common reason why people avoid creating indexes is because of the space it occupies, the best way of dealing with this kind of problem is not to stop creating indexes but instead creating nonclustered indexes. They not only occupy less space, but also make it easier for you to find data.

Clustered indexes can be of great help if your aim is to retrieve data, but if you are interested only in locating data, cluster indexes might not be the best choice. One more thing to keep in mind when using Stack Overflow Public databases is the size of the log file. As the size of your databases increase, you should also increase the size of the log file, to ensure proper functioning.

In the event of a SQL crash, all data stored in your SQL database including indexes are at risk. Hence companies which use SQL Server database should always keep a sql repair application handy to avoid incidents of data loss.
