DB: 20 database design best practices Code Use clear and uniform labels and column names, such as school, schoolcourse, and courceid. The data table name uses a singular number instead of a plural number, for example, studentcourse, instead of studentcourses. Do not use spaces for data table names. Do not use unnecessary prefixes or suffixes for data table names, such as using school instead of tbls

Introduction: Database design is one of the key points of the entire program. In order to support the relevant program running, the best database design is often not achieved overnight and can only be repeatedly explored and gradually improved. This is a complicated process, it is also a process of planning data objects in a structured database and the relationsh

if you want to index the primary key, candidate key, appropriate foreign key, potential query column, do some analysis before building. Do understand That:same Database + Different situation = Different indexing Whether it's during the day or off-peak processing, whether it's on-line processing or report processing of a database copy, the indexes are different in different cases. Do has a Primary Key on ev

Design a flexible and stable multi-layer architectureProgramIt is not easy. With mature models and applications, you also need to experience various applications and requirements. To put it bluntly, you must be able to withstand the difficulties. Recently, when restructuring your EPN framework, I have some new experiences and practices to share with you. The first is the database design. A framework

@ ssw0rd ', CONVERT (varbinary, AddressLine1), AddressID)L)M) SELECT * FROM Person. Address Question 2: how can we protect the definition of database objects and avoid exposing sensitive information during transition? The general protection measure is to use with encryption to encrypt the object when creating the object, so that the definition cannot be viewed. However, the problem is that maintenance bec

Java Database performance Best Practices Spend time evaluating the bestJDBC driverfor the application. The best driver would often vary depending on the specific deploy ment. The same application is better with one JDBC driver in one deployment and a different JDBC driver in a differ ENT deployment. If There is a choice,avoid ODBC and type 1 JDBC Dr Ivers. Java applications would typically execu

TDE encryption and Cracking Analysis of Microsoft SQL Server transparent data (Part 1) This survey started with a discussion with the customer about whether they should install TDE. If we want to select the most suitable tool for static data encryption, it is not TDE, but it has a significant defect.Video Any software that encrypts its own data has a functional

Today we will mainly talk about the DB2 Performance Tuning design and configuration of your database. There are many database design and configuration options that can affect the query performance. For more suggestions on Database Design, see the "Planning your Physical Database Design" Best

Oracle Database Import and export practices There is an Oracle server that needs to be exported and imported. I have been familiar with Oracle before, but I have never studied Oracle Export and Import. Now I am in a hurry, so I have to make up the Internet. The operation result is as follows: Oracle Data Export and ImportStep 1: Create the user's tablespace and data filesLog On As an oracle user[Oracle @ or

Preface : Before SQL Server 2005 and SQL Server 2008. If you want to encrypt sensitive data, such as financial information, payroll, or identity card numbers, you must use an external application or algorithm. SQL Server 2005 introduces the ability to encrypt built-in data, using a combination of certificates, keys, and system functions to accomplish this. Simi

PHP core technologies and practices-PHP and database basics PDO (php data object) and PHP support almost all databases on the market, but the abstract access interfaces are not uniform. Therefore, PDO has emerged and provides a common interface to access multiple databases, that is to say, the abstract database model supports connecting to multiple databases.

instructor relationship, but more precisely the alias that is declared as a instructor relationship (alias). Identifiers such as T and S, which are used to rename a relationship, are referred to as the correlation name (correlation name) in the SQL standard, but are also commonly referred to as table aliases or related variables (correlation variable) or tuple variable (tuple variable).The above query can be expressed in a better way, to find out the

"bulletproof vest", then the database storage layer encryption is tantamount to a database to do a precision surgery. These "big muscles and bones" after the data security of encrypted storage has naturally improved, but if the user access to the way the data has an impact, the need to apply the SQL statement to make

the access interface of the database. The security Agent service exists between the client application and the database storage engine, which is responsible for the encryption and decryption of the data in the library, and the encrypted data is stored in the Security Agent service.There are also some problems and limitations with this technique:1) Because of the

For a database administrator, security is one of the most important aspects to consider when protecting a database that you support. We use a variety of mechanisms and techniques to protect our data and databases, such as firewalls, authentication, and data encryption. But although we set security for our environment, there are always problems with

can use Transparent Database Encryption (TDE). This function can protect all files in the corresponding Database, no matter how many files are there. Because the files are encrypted, even if these files are copied, they cannot be used without the database master key. At the same time, this
