I remember when I first contacted the IFRAME frame, to it is not very understanding, feel the usefulness is not small, however, recently in the site with a micro-blog live control when encountered it, but also have to take the perspective of SEO to consider it, after analysis, I think the ifame framework has some advantages and disadvantages. first we need to know what is the IFRAME framework? If we use this tag on a particular page, we'll build a s

database table by the view.The view also has some drawbacks, mainly as follows.Performance: SQL Server must turn the query of the view into a query for the base table, and if the view is defined by a complex multi-table query, then even a simple query of the view, SQL Server will turn it into a complex combination that takes some time.Modify limit: When a user attempts to modify some rows of a view, SQL Server must convert it to some row of the base table. This is convenient for simple views, b

particularly stringent requirements for the time that the log is saved, but there is a limit on the total storage space, consider using capped collection to store the log data, specifying a maximum amount of storage space or documents, and MongoDB will automatically delete the capped when the threshold is reached. The oldest document in the collection. db.createCollection("event", {capped: true, size: 1048

Advantages and disadvantages of using session variables in ASP (Author: Green Apple Computer Studio) Many people use session variables to develop ASP (Active Server Pages).

Entity Bean: Provides robust data persistence. The bean container handles most of the data integrity, resource management, and concurrency features, allowing developers to focus on business logic and data processing, rather than these low-level details. When using bean-managed persistence (Bean Managed persistence,bmp) entity beans, developers write persistent code and the container determines when the code executes. When

5 Advantages of Using Stored Procedures 1. simplify complex operations by encapsulating processing in easy-to-fit units. 2. since a series of processing steps are not required, data consistency is ensured. If all developers and applications use the same stored procedure, the code used is the same. This extension prevents errors. The more steps you need to perform, the more likely an error will be.
