Delete SA and old password
One common mistake that people make about security is not to change the system admin password. You can easily ignore installation files and remaining configuration information, without properly protected authentication
, because the amount of data is small, designers and testers often only notice the implementation of the function, and rarely notice the lack of performance, until the system put into actual operation for some time, only to find that the performance of the system is decreasing, At this time to consider the improvement of system performance will cost more human and material resources, and the end result is to the whole system and a patch, so the design phase is the focus of optimization. Taking
Currently, most articles describing SQL Server 2005's new features focus on flashy features, such as sqlclr or XML data types, but the improvement of many good old T-SQL language has not received the due attention. I have heard from many DBAs that they are more excited by seeing improvements in the T-SQL language, rath
statement.
A DML trigger is a dedicated stored program that the database engine starts, and it has a significant role in establishing a review index for data changes. However, a DML trigger will only start if the data has changed. Before using SQL Server 2005, there is no better way to track the structure or security changes in the database server.
SQL Server Profiler--Identify exceptionsIn a perfect environment, all anomalies should be captured, processed, and recorded. A person regularly views these logs and creates error reports based on the exceptions that occur, so that they can be debugged in a timely manner and can avoid recurrence in the future. However, it is always possible to see that the application is constantly seeing various exceptions

Today, a friend asked the question, as shown in the topic,
confirm the source Access database. Third, select the target database as Access Data transformation, select Copy tables and views from source database in specify table replication or query, and select audit-related data tables for import/export operations. This imports the access data into the SQL SERVER Access Data Transformation database.

personally think that if most of the requests reach the second paradigm, the system will generate fewer columns and more tables, this reduces data redundancy and improves performance.

Reasonable redundancy
It is almost impossible to design a system completely according to the standardization. Unless the system is very small, it is necessary to add redundancy in a planned manner after the standardization design.
Redundancy can be a redundant database, a redundant table, or a redundant field.
"Access Data Conversion", and select "retabulation and view from the source database" in "specify table copy or query ", then, select audit-related data tables for import/export operations. In this way, the Access data is imported into the SQL SERVER "Access Data Conversion" database.
