A well-designed test
In such a business scenario, Data Writing is backflow, and usually depends on user_id queries. The data is about 0.5 billion, so I did the following test:

We already know that ASP. NET uses ADO. Net to access the database and can access the ACCESS database through the oledb connection-one of our very common low-end databases. This article discusses several error prompts that may be seen in ASP. NET, from which you can see database files created by Access 2000 and Access XP. Different error prompts will appear when access errors occur. Hope to help you
Android entry notes-data storage-SQLite, unit test
Why do we need to add three lightweight databases (SQLite) today? Because it is really light. Sqlite is a lightweight database specially prepared by unembedded devices. Although it is small, it has many functions. The biggest difference between it and other databases: MySql, SqlServer, Oracle and other databases I think is that Sqlite can only run on termin
The test process is as follows: for 4 application scenarios, from 10, 20, 50, 100 threads to the MySQL test. The test results show that: the general concurrent access to scenario 1 can satisfy the requirement, for scenarios 2 and 3) The response time is at the minute level, in 1-3 minutes and 10 minutes respectively, and for scene 4, the exception is often thrown
Time Test
This book uses a practical method to analyze the data structures and algorithms to be studied. We prefer to use a simple benchmarking method instead of Big O analysis. This test tells us how many seconds (or other time units) it takes to run a code segment. Our benchmark test time
The first test version of fireasy. Data is released today. The following is the version number of each component:
Fireasy. Common1.5.40.41422

Currently, four types of databases are supported: MSSQLServer, Oracle, SQLite, and MySQL.

Background:In the big data field, for various reasons. sometimes you need to generate a test dataset by yourself. Because the test dataset is large, you can use map/reduce to generate a test dataset. in this section (mumuxinfei), combined with some of its own practical experience, details on how to write the MAP/reduce

Our general interface testing is nothing but these kinds of measurements:1. Post the data to an interface to see how the interface returns.2. Access an interface, the interface carries different parameters, test its return situation3. Direct access to an interface (you do not need to modify the carrying parameters) to see what the interface returns. This is generally the view that the

such as throughput performance and ease of installation, but space savings are difficult to measure in a lab environment (for example, many users do not simultaneously make frequent and subtle changes to real-time data for months or years).
