With MySQL, customer resource management is in control

Mysql

MySQL is ideal for client resource management (Customer resource MANAGEMENT,CRM) systems within the support Web site. It is already an integral part of many Web sites, and its price level is unmatched. In addition, in the Dynamic Web site, there is likely to be a considerable number of CRM data to be explored.

As an administrator of the SAP Implementation Group of a telephone company, I became proficient in its superior CRM toolkit. I understand that about 90% of the work in CRM is System configuration implementation and maintenance to meet the changing requirements of the user. A CRM developer must be proficient in the design of processes and structures. Now let's talk about the process you're going through when you use MySQL to create an upgraded, High-performance CRM system.

Design a CRM solution for MySQL

The CRM database is complex: Your user form is linked to your contact method form, which is linked to your address and organization's form, which is linked to your list of things, which is linked to your table of contents, and so on. For some relationships, you need to create complex composite indexes. For other relationships, you may just need a simple index, or you don't need it at all. Updates and deletions in your implementation may or may not be stacked.

This means that you need to be extremely familiar with the tuning methods available in MySQL. But before you can make adjustments, you need to design a CRM process that relies on it to take advantage of these tuning methods.

Logic and Data Flow

As you can see in figure A, you can use the MyISAM table as the source of the report type data. This is useful because when you simply query the database, the ISAM table will be a lightning fast data source. The disadvantage of ISAM is that the table file itself may crash, and updates to its data can easily lead to such problems.

Data flow in CRM design

To resolve ISAM instability, you can use the InnoDB table to add, update, and delete records in a data table. The InnoDB engine is transactional (transactional), so if the update fails, the data is returned to the state before the change. The InnoDB is more complete on the reference, so the update of the data does not violate any relationship rules between the tables.

What is not reflected in the chart above is that you should always back up your data. In this case, the ISAM table is stored in valuable data. These forms are the things you should back up. You can get the same data in the InnoDB table, but the ISAM table is better suited to the query for the backup process.

The same is true for recovery operations on INNODB tables-they are more appropriate for updates (such as referential integrity, speed, stability, and so on), and they are automatically synchronized with any pending additions/updates. If the InnoDB table crashes, then you can use the ISAM data to rebuild the table, which is why it's best to split the process like this. After all, redundancy equals security.

Note that the line connecting table A and table B in figure A shows that it is a one-way synchronization process. It involves locking the report table (table A, ISAM), and then pushes the Update table (table B, InnoDB) back to table A. This process happens very quickly because there is no or little acknowledgement of the data at this point. MyISAM does not support it in design.

CRM for Shrink Packaging

Of course, not all CRM is designed to work with MySQL. They usually support MySQL, but they don't take advantage of their unique performance and design features. For example, SAP, PeopleSoft, and Microsoft CRM do not provide any optimization features for MySQL. That's why they're all built on Oracle and Microsoft's RDBMS design paradigm.

There are also a lot of CRM toolkits that are designed around the base of lamp (linux/apache/mysql/php). These are usually open source projects, and the benefits and costs associated with them can be imagined. Since CRM almost always involves a lot of software customization and business process analysis, it is quite willing to participate in open source development work. The design update interval provided by open source code is exactly what the system needs to synchronize with the actual operations of the enterprise, at least as much as possible.

A unique design paradigm

If you are involved in creating a CRM solution using MySQL, then you need to combine technology with business skills effectively. Matching the interface in the system to the interface in the real world requires a deep understanding of the performance enhancements available in MySQL's unique design paradigm. Understanding the MySQL thing and the composition table type will be key to understanding the paradigm, but such as indexing and keyword synthesis (key) also works.

MySQL can be used as a back-end database for common large CRM toolkits, but these toolkits are often not able to take advantage of MySQL's optimization features and design paradigms. However, many open source toolkits do take advantage of MySQL-specific features, or they can be adjusted at the source code level to take advantage of these features. This makes MySQL an ideal choice for your CRM project.
