Accessing schema-free databases
View Patent ↗Accessing a schema-free database includes constructing a model indicating a structure for the data to be used by applications accessing the data, validating the model based on the structure and on the data stored in the schema-free database, providing an API based on the structure, and accessing the database using the API. The model may be constructed by extracting data structure information from a program. The program may be written in the Ruby programming language or the Python programming language. The API may be a RESTful API.
1. A method of accessing a schema-free database, comprising:
constructing a model indicating a desired structure for data stored in the schema-free database to be used by an application accessing the data, wherein the model is constructed using data structure information for the desired structure that is specified independently of and without reference to the data or data relationships stored in the schema-free database;
generating an application program interface (API) using the model upon an automated determining that available data of the data stored in the schema-free database exists that satisfies the desired structure, including confirming that data fields in the model correspond to data properties provided in the schema-free database;
preventing the application program interface (API) from being generated upon determining that the schema-free database lacks data to satisfy the desired structure; and
the API accessing the schema-free database using the model by presenting the data stored in the schema-free database to the application in a form according to the desired structure of the model and enabling the application to manipulate data of the schema-free database when the data were part of a schema-based platform having a structure presented according to the API.
2. The method, according to claim 1 , wherein the model is constructed by extracting the data structure information from a program.
3. The method, according to claim 2 , wherein the program is written in one of: the Ruby programming language and the Python programming language.
4. The method, according to claim 1 , wherein the API is a RESTful API.
5. The method, according to claim 1 , further comprising:
constructing an optimization for each field of data provided in the data model.
6. The method, according to claim 5 , wherein the optimization is an index containing an entry for each indexed value and a corresponding node ID indicating a particular node of the schema-free database containing data corresponding to the value.
7. The method, according to claim 5 , wherein the optimization is an index containing an entry for each indexed value and a corresponding location of a node in a data file containing the schema-free database.
8. A non-transitory computer-readable medium including computer software that accesses a schema-free database, the software comprising:
executable code that constructs a model indicating a desired structure for data stored in the schema-free database to be used by an application accessing the data, wherein the model is constructed using data structure information for the desired structure that is specified independently of and without reference to the data or data relationships stored in the schema-free database;
executable code that generates an application program interface (API) using the model upon an automated determining that available data of the data stored in the schema-free database exists that satisfies the desired structure, including confirming that data fields in the model correspond to data properties provided in the schema-free database;
executable code that prevents the application program interface (API) from being generated upon determining that the schema-free database lacks data to satisfy the desired structure; and
executable code that causes the API to access the schema-free database using the model by presenting the data stored in the schema-free database to the application in a form according to the desired structure of the model and enabling the application to manipulate data of the schema-free database when the data were part of a schema-based platform having a structure presented according to the API.
9. The non-transitory computer readable medium, according to claim 8 , wherein the model is based on the data structure information from a program.
10. The non-transitory computer readable medium, according to claim 9 , wherein the program is written in one of the Ruby programming language and the Python programming language.
11. The non-transitory computer readable medium, according to claim 8 , wherein the API is a RESTful API.
12. The non-transitory computer readable medium, according to claim 8 , wherein the software further comprises:
executable code that constructs an optimization for each field of data provided in the data model.
13. The non-transitory computer readable medium, according to claim 12 , wherein the optimization is an index containing an entry for each indexed value and a corresponding node ID indicating a particular node of the schema-free database containing data corresponding to the value.
14. The non-transitory computer readable medium, according to claim 12 , wherein the optimization is an index containing an entry for each indexed value and a corresponding location of a node in a data file containing the schema-free database.
15. A method of accessing a schema-free database, comprising:
constructing a model indicating a desired structure for data stored in the schema-free database to be used by an application accessing the data, wherein the model is constructed using data structure information for the desired structure that is specified independently of and without reference to the data or data relationships stored in the schema-free database;
generating a dynamic application program interface (API) platform using the model upon determining that available data of the data stored in the schema-free database exists that satisfies the desired structure, including confirming that data fields in the model correspond to data properties provided in the schema-free database;
preventing a dynamic application program interface (API) platform from being generated upon determining that the schema-free database lacks data to satisfy the desired structure;
the API accessing the schema-free database using the model by presenting the data stored in the schema-free database to the application in a form according to the desired structure of the model and enabling the application to manipulate data of the schema-free database as if the data were part of a schema-based platform having a structure presented according to the API; and
accessing an index to obtain a node in the schema-free database, wherein the node corresponds to data accessed through the API and wherein the index contains an entry for the data and a corresponding entry indicating the node, the API presenting a schema-based interface to the application to facilitate arranging, according to the desired structure, of the data stored in the schema-free database without the data being stored in any schema-based platform.
16. The method, according to claim 15 , wherein the entry indicating the node is a node ID.
17. The method, according to claim 15 , wherein the entry indicating the node is a location of the node in a data file containing the schema-free database.
18. The method, according to claim 15 , wherein the API is a RESTful API.
