采用哪种 DAL 方法?

ActiveRecord 通常限制太多。然而,就团队中每个成员对使用 ORM 的看法而言,我处于一个困难的境地。我们目前使用一个非常基本的 ActiveRecord ,遗憾的是我说它主要是用一些基本的代码生成来手工编写的。我想为我们构建一个新的DAL,但避免ActiveRecord的限制,所以DDD更是如此。然而,我反对的观点是(老 skool 开发人员和我自己都很年轻):

团队首席开发人员

  • 赞成存储过程,但不一致......有些只是得到 一个表,例如 SELECT * FROM Company,有些得到 SELECT C.*, O.OtherTableValue FROM Company C...(非常令人沮丧)
  • 并不真正了解某些最新 ORM 工具的好处
  • 不会承诺使用任何工具它“限制太多”,如果有 问题你做什么?

DBA

  • 不喜欢动态 SQL
  • 不喜欢 SELECT *

我并不是说以上内容是禁止的,否则更能说服他们。我相信我们可以通过使用 ORM 来大幅提高效率,但很难说服他们不这样做。如果我能够在其中一些领域提供证据,我也许能够说服他们,即使是在他们最初不知道然后看到好处的情况下秘密实施。

您可以提供什么建议来帮助我的情况?我相信很多开发人员都遇到过这个问题,并且无法选择他们想要使用的架构。

ActiveRecord is too limiting normally. However, i'm in a difficult situation in terms of the views held by each member of the team in regards to using ORM's. We currently use a very basic ActiveRecord with regret I say is written mostly by hand with some basic generation of code. I would like to build a new DAL for us but avoiding the limitations of ActiveRecord, so DDD more so. The points however I am battling against are (both old skool developers and myself quite young):

Team Lead Developer

  • Is in favour of stored procedures, but isn't consistant...some just get
    a table e.g. SELECT * FROM Company and some get SELECT C.*, O.OtherTableValue FROM Company C...(very frustrating)
  • Doesn't really know the benefits of some of the latest ORM tools
  • Won't commit to any tool as its "too restrictive" and if there are
    issues what do you do?

DBA

  • Doesn't like dynamic SQL
  • Doesn't like SELECT *

I'm not saying the above are off limits, its more convicing them otherwise. I belive we could massively improve our efficent with the use of an ORM but its very difficult to convince them otherwise. If I could give proof to some of these areas I might be able to convince them, even by implementing under the covers without them knowing initally and then seeing the benefits.

What advice can you give to help my situation? I believe many developers come across this and cannot choose which architecture they would like to use.

我认为您的团队负责人需要要么致力于一致性,要么花一些时间在 ORM 研究项目上以提出使用建议。换句话说,一个不一致且固定的团队领导不应该担任这个角色。

其次,出于多种原因,我倾向于同意你们的 DBA 的观点。只要他/她足够灵活,知道在某些情况下动态 SQL 会更好地解决问题。

对于您的具体情况,我会要求您的 DBA 制定法律,规定每次都使用存储过程,除非根据具体情况提供理由,并通过策略和监控来强制执行。这将解决一致性问题。也许有了这个政策,ORM 看起来比必须向团队负责人手动编写所有内容更具吸引力。

I think your Team Lead needs to either commit to consistency or spend some time on an ORM research project to make a recommendation to use. In other words, an inconsistent and set-in-ways Team Lead shouldn't be in that role.

Secondly, I tend to agree with your DBA for a number of reasons. As long as he/she is flexible enough to know that there are occasions where dynamic SQL will solve the problem much better.

For your specific situation I'd say ask your DBA to lay down the law that stored procs are to be used every time unless justification is provided on a case-by-case basis and enforce this through policy and monitoring. This will address the consistency issue. Perhaps then, with that policy in hand, an ORM looks more enticing than having to hand-code everything to the Team Lead.

首席开发人员应该听取 DBA 的意见。 “SELECT *”不好。从首席开发人员的要点来看,这听起来像是一场熟悉的艰苦战斗。有时,在这种情况下阻力最小的方法是使用 ORM(例如 NHibernate)实现某些内容,并为团队安排某种演示。

鼓励他们的意见,特别是来自首席开发人员和 DBA 以及任何其他反对者的意见。他们可能有合理的抱怨,随着您对该工具的了解更多,这些抱怨实际上可以通过该工具得到解决。另一方面,他们可能只是因为没有充分的逻辑原因而坚决反对。如果是这样的话,最好找出来,因为这很可能意味着在这场针对他们的争论中无法获胜,因为他们并没有真正进行辩论。

The lead developer should listen to the DBA. "SELECT *" is bad. And from the bullet points about the lead developer it sounds like you've got a familiar uphill battle. Sometimes the path of least resistance in that situation is to implement something using an ORM (such as NHibernate) and schedule some kind of demonstration to the team.

Encourage their input, specially from the lead developer and the DBA and any other nay-sayers. They might have legitimate gripes that can actually be solved with the tool as you learn more about it. On the other hand, they might just be dead-set against it for no good logical reason. If that's the case, it's best to find that out because it could very well mean that there is no winning this argument against them, because they're not really debating.

他们反对使用 ORM 的理由是什么?如果他们不仅仅是固执和顽固,那么如果你知道他们具体反对你的是什么并解决这些问题。和其他人一样,我认为您的 DBA 是正确的。但如果他担心动态 sql 的 SQL 注入,ORM 会在一定程度上缓解这个问题。选择 * 应该是解雇的理由。

我认为你应该在一些小东西上使用 LINQ-to-SQL 或 subsonic 或 nhibernate。表明使用 ORM 可以使开发更快、更干净。

What are their objections to using an ORM? If they are not just being obstinate and stubborn then if you know what specifically they object to you and address those concerns. Like the others I think your DBA is correct. But if he is concerned about SQL injection from dynamic sql, ORM's alleviate that issue somewhat. Select * should be grounds for a firing.

I'm of the mind where you should just use something, LINQ-to-SQL or subsonic or nhibernate on something small. Show that development can be faster and cleaner using an ORM.
