Design of LRS in Context of Indian Environment




After having a careful study of land record data the following seven entities of interest were identified: - Collector, Owner, Cultivator, Irrigation-Source, Plot, Revenue-Paid, Estate (a brief explanation of entities with their attribute level description is given in Appendix 2)

The old record (i.e. land record maintained manually in register) information like Account Number and Sub Account Number are added as attributes in the entities Owner and Cultivator. These attributes will help in tracing the old land records in register from computerized LRS.

The ER diagram as shown in Fig.1 explains the relationships among entities [23]. To provide clarity of expressiveness only entities and attributes of relationships are shown in ER diagrams (Fig.1 & 4). See Appendix 2 & 3 for attributes of entities.

In order to develop nationwide LRS, there is need to develop a uniform addressing mechanism to a plot. The conventional hierarchical addressing used to refer a plot in different regions of the country is shown in Fig.2. In Fig.3 the same conventional hierarchy is shown except the general terms Division1 and Division2 are used in place locally used terms. Division2 can further be divided into smaller hierarchical units with the consultation of district and state level concerned officials. New entities of interest in the generalized nationwide LRS can be: State, UT, District, Division-1, Division-2, Reference-Point Other entities can be revised to give them generalized form as Plot, Owner, Land-Inspector, Tenant, Irrigation-Source, Revenue-PaidThe term Land-Inspector and Tenant are used for Collector and Cultivator to give them general sense. (attribute level description of these entities is given in Appendix 3) ER diagram for nationwide LRS can be given as shown in Fig.4.



The scheme proposed for nationwide LRS can be extended further to include information about basic amenities available in the town / village / district in a single database. The basic amenities can be education, health, entertainment, drinking water, bank, electricity, road, post office, telephone, highway connectivity etc. The other useful information like population, sex ratio, literacy, per man income, rain fall, crop etc. can also be included. This extended system will help district administration to have a close watch on balance development of the whole district and to convey latest data to state or central govt. for further processing. The state and central governments will use these data for macro level planning and to decide appropriate funds for various development activities. The exact structure of information for nationwide system can be decided only after consultation the requirements with district, state and central govt. level concerned officials. The entities in nationwide LRS can be extended to include new attributes required for nationwide information system, however few new entities will also be required to consider. The extension of entities to include new attributes will be as under: -

Plot Plot-Code , LandType, Area, Shape, Map, P-Location, Crop, DrinkingWater, ElectricityConnection, OtherData1, OtherData2,…,OtherDataN
Division-2 D2-Code , D2-Name, D2-Area, D2-Population, D2-SexRatio, D2-PerManIncome,
D2-HighwayConnectivity, D2-PrimaryHospital, D2-Theatre, D2-School, D2-College,
D2-BusStand, D2-Bank, D2-Postoffice, D2-telephone, D2-CropProduction, D2-RainFell,
OtherData1, OtherData2,…,OtherDataN
Division-1 D1-Code , D1-Name, D1-Area, D1-Population, D1-SexRatio, D1-PerManIncome,
D1-Hospital, D1-NumberOftheatre, D1-NumberOfSchool, D1-CropProduction,
D1-RainFall, OtherData1, OtherData2, …,OtherDataN
District D-Code ,D-Name, OtherData1, OtherData2,…,OtherDataN
State State-Code ,S-Name, OtherData1, OtherData2,…,OtherDataN
UT UT-Code , UT-Name, OtherData1, OtherData2,…,OtherDataN


New entities of interest may be: Bus Stand, Primary School, Primary Hospital, District Hospital, Regional Hospital, College, Bank, Post Office, Theatre etc. If we need to know details about entities like Hospital, Bank, College etc. then there is need to define these entities separately. If we need only the number of these basic amenities in a particular division or district then the extended entities are sufficient by providing additional attributes as yes/no values and the same ER diagram as described for nationwide LRS will also work for nationwide information system.
