 It can cooperate with NoSQL and NewSQL, which keep staying in the cutting edge of technology and recommendable. Meanwhile, Sharding-Sphere focuses on technologies remaining stable and changeless so as to grasp the intrinsic quality. 
 Relational Database is still the cornerstone of core business in enterprises and possesses huge market share. It is difficult to estimate trendy in future and now we focus on how to enhance the capacity of Sharding-Sphere with Relational Database.

 Database Mesh emphasizes how to connect distributed data-access-layer with databases. It pays more attention to interaction, which means the messy interaction between applications and databases will be effectively orchestrated. 
 By using Database Mesh, applications and databases will form a large grid system, where they just need to be put into the right position accordingly. They are all governed by mesh layer.

 Sharding-Sphere定位为关系型数据库中间件，旨在充分合理地在分布式的场景下利用关系型数据库的计算和存储能力，而并非实现一个全新的关系型数据库。
 它与NoSQL和NewSQL是并存而非互斥的关系。NoSQL和NewSQL作为新技术探索的前沿，放眼未来，拥抱变化，是非常值得推荐的。反之，也可以用另一种思路看待问题，放眼未来，关注不变的东西，进而抓住事物本质。关系型数据库当今依然占有巨大市场，是各个公司核心业务的基石，未来也难于撼动，我们目前阶段更加关注在原有基础上的增量，而非颠覆。
