foreign key relationship - ServiceStack Service structure for predominantly read-only UI -

-

i'm getting started servicestack , i've got i'm impressed has under bonnet , how easy use!

i developing predominantly read-only application it. there updates database 3 or 4 times year rest of time solution displaying data on electronic information board (large touch screen monitor).

the database structure normalised few foreign keyed tables , in mind think may best separate read api crud api. crud api can used create , modify relational data poco classes matching database tables. ensure read-only api flattens relational data few pocos spanning few db tables making data easier handle on read-only uis.

i'm looking ideas , advice on whether separation of concerns wasted effort or if there better way of achieving need? has had similar thoughts / ideas?

having developed similar read application (a gazetteer, updated quarterly/yearly) using servicestack went optimizing api reads, making use of built in caching:

    // cached responses has object     public object any(cachedrequestdto request)     {          string cachekey = request.cachekey;         return this.requestcontext.tooptimizedresultusingcache(             base.cache, cachekey, () =>                 {                     using (var service = this.resolveservice<requestservice>())                     {                         return service.any(request.translateto<requestdto>()).translateto<cachedresponsedto>();                     }                 });     }

where cachekey just:

    public string cachekey     {                 {             return urnid.create<cachedrequestdto>(string.format("{0}_{1}", this.field1, this.field2));         }     }

we did start creating crud / poco service, speed went using bulk import tools such sql server dts/ssis or console apps suffices now, , revisit later if required.

might want consider cqrs.

also found following article valuable when starting implement additional search type services: https://mathieu.fenniak.net/stop-designing-fragile-web-apis/
