Reach objects
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a row level security. One of the methods includes receiving, by a computer device executing at least part of a functional logic tier of an application, a request from a user for one or more objects present in the functional logic tier. The method includes determining that a type of the requested objects is associated with an object representative of instance level security. The method includes in response to determining that the type is associated with the object, determining access is authorized to at least some of the objects, determining access comprising accessing, by a computer device executing at least part of a data tier of the application, a link data structure that links the user with at least some of the objects. The method also includes providing the at least some of the objects to the user.
1. A computer implemented method for providing instance level security in an object-oriented application comprising:
receiving, by a computer device, executing at least part of a functional logic tier of an application, a request from a user for one or more objects present in the functional logic tier, the functional logic tier comprising objects, each object having a type;
determining that a type of one of the one or more requested objects is associated with an object representative of instance level security;
in response to determining that the type is associated with the object representative of instance level security, determining access is authorized to at least some of the one or more objects, determining access comprising:
obtaining a data access statement configured to obtain data associated with the one or more objects from a data store;
altering the data access statement to access an instance level security feature of the data store;
accessing, by a computer device executing at least part of a data tier of the application, a link data structure in the data tier of the application that links the access authorized user with at least some of the one or more objects using the altered data access statement; and
providing the at least some of the one or more objects to the access authorized user;
wherein multiple objects representative of instance level security are associated with the link data structure;
wherein the object representative of instance level security is associated with a name and wherein determining the user is authorized to access at least some of the one or more objects is based at least in part on the name.
2. The method of claim 1 , wherein the multiple objects representative of instance level security are associated with the same type of object.
3. The method of claim 1 , wherein securing the object using the object representative of instance level security does not require change to a user interface accessing the business object.
4. The method of claim 1 , wherein the link data structure is a table in a relational database.
5. A non-transitory computer storage medium encoded with computer program instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:
receiving, by a computer device, executing at least part of a functional logic tier of an application, a request from a user for one or more objects present in the functional logic tier, the functional logic tier comprising objects, each object having a type;
determining that a type of one of the one or more requested objects is associated with an object representative of instance level security;
in response to determining that the type is associated with the object representative of instance level security, determining access is authorized to at least some of the one or more objects, determining access comprising:
obtaining a data access statement configured to obtain data associated with the one or more objects from a data store;
altering the data access statement to access an instance level security feature of the data store;
accessing, by a computer device executing at least part of a data tier of the application, a link data structure in the data tier of the application that links the access authorized user with at least some of the one or more objects using the altered data access statement; and
providing the at least some of the one or more objects to the access authorized user;
wherein multiple objects representative of instance level security are associated with the link data structure;
wherein the object representative of instance level security is associated with a name and wherein determining the user is authorized to access at least some of the one or more objects is based at least in part on the name.
6. The non-transitory computer storage medium of claim 5 , wherein the multiple objects representative of instance level security are associated with the same type of object.
7. The non-transitory computer storage medium of claim 5 , wherein securing the object using the object representative of instance level security does not require change to a user interface accessing the business object.
8. The non-transitory computer storage medium of claim 5 , wherein the link data structure is a table in a relational database.
9. A system comprising: one or more computers comprising one or more processors, memory, and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
receiving, by a computer device executing at least part of a functional logic tier of an application, a request from a user for one or more objects present in the functional logic tier, the functional logic tier comprising objects, each object having a type;
determining that a type of one of the one or more requested objects is associated with an object representative of instance level security;
in response to determining that the type is associated with the object representative of instance level security, determining access is authorized to at least some of the one or more objects, determining access comprising:
obtaining a data access statement configured to obtain data associated with the one or more objects from a data store;
altering the data access statement to access an instance level security feature of the data store;
accessing, by a computer device executing at least part of a data tier of the application, a link data structure in the data tier of the application that links the access authorized user with at least some of the one or more objects using the altered data access statement; and
providing the at least some of the one or more objects to the access authorized user;
wherein multiple objects representative of instance level security are associated with the link data structure;
wherein the object representative of instance level security is associated with a name and wherein determining the user is authorized to access at least some of the one or more objects is based at least in part on the name.
10. The system of claim 9 , wherein the multiple objects representative of instance level security are associated with the same type of object.
11. The system of claim 9 , wherein securing the object using the object representative of instance level security does not require change to a user interface accessing the business object.
12. The system of claim 9 , wherein the link data structure is a table in a relational database.
