What resources do you use to help you in your developments/app builds? ✅ Please take part in our 5-min survey.

Hi Developers! Want to raise security discussion today! Let's discuss how InterSystems security for applications works. In general, the concept is clear: we have Resources (what to protect), Roles which combine a set of privileges and accesses to Resources and Users which can have this or that Role. But there is also a concept of Application which also could have a Role. So you either provide a Role for a User or for an Application. What do you use in production? What is your strategy and why? Pros, cons? The applications you mentioned, it's not exactly applications, it's just kind of entrypoint to the application. Security in Caché and in IRIS now, was not so good in my opinion, for many reasons. An application developer, if he would like to use role-based security is too limited to use the Security model from InterSystems. And no matter how many different applications customers would like to use on their own Instance of IRIS, security will be global. Issues with mirroring, with ECP, any instance of IRIS use own tables, and have to be synchronized in some ways. Such big clusters should have the ability to use the same security settings on any instance, out of the box. Application, real, not virtual, should have the ability to re-use Security and store it close to Application's data. Security settings synchronization for mirroring and ECP is a different problem though a serious one. But there are strong recommendations from very experienced specialists to follow the Application-based security model. I want to have a discussion around - what are the key reasons for it? I think both should be used. If an application needs some privilege for itself (=for all users), e.g. for reading database with code, then this should be role for the application. If different users within same application have different permissions then this should (can) be handled via user roles.

And see you at InterSystems AI+ML Summit 2021! Hi In which time zone are the times for the presentations? If I am in South Africa which is GMT+2 in GMT terms what are the times for these presentations? Is the seminar being held in Germany in which case I can probably work it out via google but it's not clear other than the announcement says that the presentations will be available in English and German. Hence my assumption that its being held in Germany. Thanks Nigel Hi Nigel, Scheduled sessions are based on Central European Time (CET) time. If you click on the link of the session you are interested in, the time zone in which you are located will be automatically pulled up. To find out in what language the session will be, just look at its description by clicking on the link. If the description is in English, then the speakers will present materials in English.

I'm participating in the Developing with InterSystems Objects and SQL with Joel Solon. The course is very nice and I will share with you some tips I got during the training. Tips presented in the day 4: All data are stored in Globals and Global names start with ^. Example of global: ^animal. Global can have multiples locations to the data ("sub data"). Example: ^animal(1). ^%* globals are accessible from any system-wide (from any namespace). Globals enables IRIS to support multimodel data (object, relational, document, multidimensional, etc). To see globals go the Management Portal > Explorer > Globals > Select Global > View or in Terminal type do ^%G or zwrite ^global. There are an automatic correspondence between persistent classes and SQL Tables: Package is SQL Schema; Class is a Table; Property is a Column; Method is a Store Procedure; (when sqlProc); Relationship between classes is a SQL Foreign Key constraint (must be bi-directional); Object is a Row. One table can correspond to multiple classes, but serial class is part of the table of the persistent class (don't have a specific table). One class can correspond to multiple tables. We have some classes types: Non-registered: not class object (container for methods only); Registered: transient objects; Persistent: SQL persistence in tables; Serial: SQL persistence in the main table (serial is embedded); Datatype: not class object is used to do new validations and conversions to base data types. Classes can be composed by: Properties; Methods; Class queries: SQL Select statements; Parameters: user constants or system constants to configure the class behavior; Foreign keys: to referencial integrity; Indexes: to improve performance and do unique values; Triggers: fire methods associated with persistence events; XData: XML or JSON definitions associated with the class; Storage: description of the data storage. Classes by convention has first letter of the word in Capital. Example: CountryOrigin. Parameters are all capital. Example: COLORNUMBER. Class attributes qualify/configure a class. Example [SqlTableName = Animal] set the table name to a class. [Final] not allows inheritence. [Private] not allows call methods or use properties for non-subclasses. Internally IRIS generate Get and Set to properties, and are not visible but can be declared to change the behavior. Is possible override a method of the superclass, to do this, repeat the class name, the arguments. Is possible increase the number of arguments, not decrease. Use ##super() to call base class method. To create abstract class use [Abstract] and prevent instantiation. Is possible extends multiple classes. Example Class Person extends (%Persistent, %Animal). (Persistent must be the fisrt in the extends, see joel tip in the comments) REST is REpresentational State Transfer. Is based in the HTTP protocol. Use HTTP verbs: GET (select), POST (insert), PUT (update) and DELETE (delete). For expose your class as REST resource extend from %CSP.REST. Use URLMap inside XData block to configure the routes of your REST service. Using the Portal, create a Web Application, enable REST and specify Dispatch class. %JSONAdaptor provides convertion between objects and JSON. Use obj.%JSONImport(jsonObj) to assign DynamicObject to a object. Use obj.%JSONExportToString(.jsonString) to write a JSON String to a object. %JSON.Formatter format a JSON String for human readability. Good tips! Congrats! Could you give an example for items 6 and 7? I always thought that the relationship was a class for a table. 6 & 7 are side effects of object inheritance.Think of a class Person.But Employee Extends PersonSimilar Students Extends Person tooSo you have 3 tables but all are Persons Some with extension some not. @6: Table Employee corresponds to class Person and to class Employee @7: So class person corresponds to Table PERSON, EMPLOYEE , STUDENT Yes, thanks the nice example. Regarding 9, can we change the stored information manually? I know it is generated automatically. @9.9. storage is generated once if not existing yet.you may change it manually (typically data location global) as long as there is nothing stored yetotherwise you lose the existing content. Or you copy it to the new location.My article The adopted Bitmap shows such an example [actually also in contest} Hello YURI MARX GOMES, Thank you for your articles. Always good tips Thanks @Delphine.Morel, good to hear this, is an incentive to keep writing more articles. Point 5-5: Relationship on the object side is bi-directional. Class A has a reference to class B, and class B has a collection of references to class A. On the SQL side, table A has a reference to table B, along with automatic referential integrity. Point 16: Important: for a class to be persistent, %Persistent must be the first class. So the example should be: Class Person extends (%Persistent, Animal) Thanks additional tips! If there is no storage definition then a storage definition whose type is %Storage.Persistent is created when compiling the class. This is done before the storage definition is compiled (every class member is compiled by the class compiler). Then, when the storage definition is compiled and if the type is %Storage.Persistent then the %Storage.Persistent.STORAGECOMPILERCLASS will generate a full storage definition for the current class definition. What does that mean? Well - if this is the first time this storage definition has been compiled then it is most likely empty, other than the type class. The STORAGECOMPILERCLASS will generate a complete storage definition. But even if the storage definition is already defined, the STORAGECOMPILERCLASS still reviews that definition. If there are any changes detected to the class definition then the storage definition is updated to reflect those changes. That means that the user can manually edit the storage definition at any time and the storage compiler will simply make sure that the definition is "complete" - no missing properties, no missing indexes, and so on. Bottom line is that the user is free to make any desired changes, including deleting the storage definition completely. Keep in mind that some changes can make the compiled class incompatible with existing data. Just to clarify - inheritance considers the primary super class hierarchy. %Persistent must be the first class some where in the primary super class hierarchy. Sample.Employee extends Sample.Person which extends %Library.Persistent. Great, thanks!

I finished my participation in the Developing with InterSystems Objects and SQL with Joel Solon. The course is very nice and I will share with you some tips I got during this the training final day. Tips presented in the day 5: %SYSTEM package has general utiliy classes. Use $system.class.Help() to list the utilities. The main %SYSTEM classes are Encryption (industry encryption methods), OBJ to manage classes and objects, Security for security methods and SQL to use SQL language. IRIS allows validation to the properties and arguments using MINVAL and MAXVAL to integer, FORMAT to date and time, SCALE to decimal, MINLEN, MAXLEN, TRUNCATE, VALUELIST (restrict the input to a list of values) and PATTERN to string. Example: Method Print(name As %String(MAXLEN=50)). You can create new data type validations and convertions extending a datatype like %String and using DisplayToLogical() and LogicalToDisplay() to implement new behaviors. Is possible change the datatype parameter like the PATTERN parameter for change the validation of a string. IRIS uses -> operator to do implicit joins, example: select Country->States->County from Simple.Places. This joins 3 related tables. To create a reference between classes/tables use ForeignKey. Example: ForeignKey CountryFK(Country) References Simple.Country() [ OnDelete = setnull ]. There are the options setnull to set null to the otherside table/class, cascade to propagate the deletion, noaction to no action and setdefault to configure a default value to the reference. Use %ConstructClone() to do a clone of a object and its references. Use SqlComputeCode to the calculated fields. Example: (from IRIS documentation) Property FullName As %String [ SqlComputeCode = {set {*}={FirstName}_" "_{LastName}}, SqlComputed ]; Is possible automate tests using %UnitTest framework. Use %UnitTest.TestCase for defining test cases and %UnitTest.Manager for running a set of Test Cases. To see the results go to System Explorer > Tools > UnitTest Portal. See https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=TUNT. IRIS supports 2 type collections: List: key based on position starting in 1. Declaration: Property States as list of Simple.State. Get: country.States.GetAt(1) Insert: country.States.Insert(florida) Remove: country.States.RemoveAt(1) Count: country.States.Count() Clear: country.States.Clear() Next: country.States.GetNext(1) - to get item 2 Loop: for i=1:1:country.States.Count() { write !, country.States.GetAt(i) Array: key based on associated value. Declaration: Property States as array of Simple.State. Get: country.States.GetAt("FL") Insert: country.States.SetAt(florida, "FL") Remove: country.States.RemoveAt("FL") Count: country.States.Count() Clear: country.States.Clear() Next: country.States.GetNext("FL") - to get item GA Loop: set state = "" for { set val = country.States.GetNext(.state) quit: (state = "") write !, val } To create relationships between classes, we have: Parent/Children: Relationship States as Simple.State [ cardinality = children, Inverse = Country ]. The otherside: Relationship Country as Simple.Country [ cardinality = parent, Inverse = Country ]. One/Many: Relationship States as Simple.State [ cardinality = many, Inverse = Country ]. The otherside: Relationship Country as Simple.Country [ cardinality = one, Inverse = Country ]. One-To-One and Many-to-Many are not supported. One-To-One may be simulated and Many-To-Many can be made using 2 Many-to-One to a relationship table. Stream is object that can contain amount of data larger than limit of regular properties, may store characters (%Stream.GlobalCharacter) or binary (%Stream.GlobalBinary) data. Use the following methods to read/write data: Write(text): write in the end of line; WriteLine(text): write to a new line; Clear(): clear the content of the stream; CopyFrom(stream): copy from a stream and overwrite the current content; Read(length): read characters limited to the length; ReadLine(length): read characters in the current line limited to the length; Rewind(): retorna para o início do stream; MoveToEnd(): move to end of stream. You can use triggers to do something before or after a CRUD event. Example: Trigger T1 [Event = INSERT, Time = AFTER, Order = 1, Foreach = row/object] { write your code }. The IRIS has some functions frequently used: $EXTRACT: get a substring - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_fextract $FIND: get the position of a value passed as argument - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_ffind $LENGTH: get the size of a string or substring - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_flength $LIST: return/create a list of elements - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_flist $LISTDATA: return the element in the list by position - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_flistdata $LISTFIND: return the index of a element in the list - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_flistfind $LISTGET - get an element in the list - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_flistget $LISTLENGTH - get total of elements in the list - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_flistlength $PIECE - return or replace a substring using a delimiter - https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_fpiece The course was very nice and has a rich set of practical exercices. The course is important to preparation to IRIS developer certification too. See the course agenda in https://www.intersystems.com/support-learning/learning-services/classroom-learning/?course-view=course-schedule. @11: 1:1 could be a degraded 1:N relationship orby inheriting from a base class as mentioned earlier: "Employee Extends Person" many-to-many can be covered as M:N relationship as I described in my article 3 years ago. Thanks Cemper. Point #11: one-to-one is not supported but can be imperfectly simulated. many-to-many is supported by combining one-to-many among 3 classes. Oops! I posted this without noticing that Robert already handled this one! Perfect! Thanks the contribution! The interactive tutorials with exercises built into the documentation helped me a lot in my time: Caché Tutorial Topics Map Caché Tutorials Also included was a database "SAMPLES" (code and data) with examples for every taste. I often used it for performance testing. Note: I give a link to version 2016.2, because since version 2017.1, for some reason, the developers have changed the display styles in the online documentation and removed some information. Local documentation does not have these disadvantages. In addition, in the <cachesys>\dev\ folder there were numerous demos with source code for various programming languages and connection technologies (С++, C#, Java, PHP, Python, ODBC, JDBC, ADO.NET, ActiveX, XEP, etc.): Incomplete content \dev\tutorials\ \dev\tutorials\csp \dev\tutorials\java \dev\tutorials\mv \dev\tutorials\pojo \dev\tutorials\security \dev\tutorials\UnitTestEx \dev\tutorials\webservices \dev\tutorials\zen \dev\Cache\ \dev\Cache\callin \dev\Cache\callout \dev\Cache\cctrlcpp \dev\Cache\cctrlvb \dev\Cache\ctrldemo \dev\Cache\HAcluster \dev\odbc\samples\ \dev\odbc\samples\php \dev\odbc\samples\select \dev\odbc\samples\sqlgateway \dev\python\ \dev\python\samples \dev\python\samples3 \dev\cdirect \dev\cpp\samples \dev\dblib\samples \dev\dotnet\samples \dev\java\samples \dev\mv\samples \dev\node.js\samples \dev\perl\samples Great tip, thanks! I think Objects and Groovy are actually a bit similar... I don't know if my idea is right or wrong, actually I write very little Objects. Thank you for sharing your experience, It seems to be an enriching training
